An 8-year-old child has 100 degrees after mydriasis. Do I need glasses?

Today, I would like to share with you a user’s consultation. The child is 8 years old and 100 degrees after mydriasis. Do I need glasses?
Question: A few days ago, 150 naked eyes were checked, and 100 degrees after pupil dilation. The doctor asked to wear glasses. What should I do?
A: Judging from the data checked above, the refraction after mydriasis is indeed 100 degrees myopia in both eyes. This is what we call true myopia. For 8-year-old children, myopia growth is expected to be faster. It is recommended to Carry out active prevention and control. The main considerations are from three aspects: 1. Environmental factors: mainly to improve lighting, go outdoors as much as possible, outdoor lighting is much higher than indoor, and artificial lighting is currently difficult to simulate, outdoor time is at least 10h a week, but after entering myopia, The role of outdoor prevention and control is relatively limited, so the second optical method needs to be combined; 2. Optical control: the optical effects involved in special defocus can control the development of myopia, this category mainly includes OK mirrors, new music frame mirrors, multi-focus soft Mirrors, multifocal RGP, etc., if you mind wearing glasses for a long time, you can give priority to OK glasses (but need to try to evaluate before you can finalize), if you don’t mind wearing glasses for a long time, you can give priority to new music learning; 3 . Drug control: Low concentration atropine is a prevention and control method that can control myopia, but this drug is currently not officially approved by SFDA in China, the purchase route is relatively limited, and the side effects are also unclear, so usually the above two controls are still Consider using it if it is insufficient. Therefore, for the current situation, it is recommended to increase outdoor + optical correction. Before adopting prevention and control measures, try to improve the eye axis examination as much as possible to facilitate subsequent evaluation of prevention and control effects.
The user asked: Thank you! At present, we should try our best to increase the degree of vision and protect it. The glasses still have to be paired, right, but do they wear them all the time, even in life?
A: Yes, the current focus is still on controlling the development of myopia. Wearing a frame lens, in principle, it is recommended to wear it regularly (unless there is an inclination, you can consider not wearing it). If you are wearing a control lens such as Xinlexue, it is recommended to wear it regularly. You can wear it regularly to ensure the control effect.

Children with myopia need early intervention

The earlier myopia occurs, the greater the chance of developing deep myopia and pathological myopia, and the higher the risk of complications. Myopia is irreversible, and childhood is a critical period of vision development. Once a child is found to have myopia problems, he should intervene as soon as possible to stabilize the child’s myopia degree and control the degree of further development. How do children and adolescents use their eyes healthily? 1. The use of electronic products should not exceed 1 hour per day; 2. Persist in outdoor exercise for more than 2 hours a day; Start at the age of 3 and 3, regular eye examination; 4. The reading distance is at least 40 cm; 5. Use the eye for 40 minutes, rest Or look out for 5-10 minutes.

The past and present of a new type of artificial lens special scissors

The design stems from seeing a pair of scissors in the kitchen one day in life. It is very special. Unlike ordinary scissors, one of the two cutting edges is jagged and the other is the same as ordinary scissors. I asked my wife what this is doing use? Answer: “Cut food! In addition to vegetables, cutting raw meat or bone-bearing fish is super easy to use, and the one-sided zigzag design will be firmly bitten when cutting, and will not slip… “Barabara said a lot, I joked, “If the shopping guide of the supermarket can introduce you like you, the sales of this pair of scissors must be very good!” What impressed me most in this conversation was that “the single-sided zigzag design can It bites the food well and prevents slipping during the cutting process!” Reminds me that the ophthalmic intraocular lens also needs to be cut during the removal operation. The lens is very easy to slip during this process, but it is currently on the domestic market. None of the surgical scissors has a zigzag design! If the zigzag cutting edge design can effectively prevent slip, why not use this design for crystal cutting? With this idea in mind, he found another ordinary pair of scissors from home and used these two scissors to cut different kinds of food in the kitchen for comparison. Finally, it was concluded that the sharpness of the serrated scissors is almost the same as that of ordinary scissors, but the anti-slip effect is indeed better than the serrated ones. Although it is a very small verification, but at this moment, I can’t suppress my inner excitement, I immediately started to design and draw the crystal shear, and I found a manufacturer to create a sample. After many modifications and adjustments, I got a more satisfactory artificial crystal shear , Tried it out in a simulated environment, and it performed extraordinary! He also designed a double-edged saw-shaped crystal cutter and applied for a patent together. (The picture is the original design manuscript and the first sample of scissors, please ignore my non-professional hand painting) The product is suitable for cutting intraocular lens in intraocular lens replacement surgery. (What is an intraocular lens? For details, see: “Science | Cataract Ultrasound Emulsification”) Product Features Zigzag cutting edge: increase the friction between the cutting edge and the crystal, effectively reduce the possible slippage of the crystal during the cutting process, thereby reducing Complications occur. Lengthening of cutting edge: the crystal can be cut at one time without cutting back and forth multiple times, improving the efficiency and safety of the operation. Small blade design: It can enter the eye through a 2mm incision. The arc design of the blade: better protection of the corneal endothelium, iris tissue and posterior capsule to avoid side injury caused by surgical operation.

A first look at the topographic map of Placido disk cornea

In a fitting, safe, and effective orthokeratology fitting process, accurate interpretation of the corneal topography can definitely play a multiplier role, and understand the actual role of each important parameter in the corneal topography. Guide the selection of lenses, evaluate the shaping effect of the lenses, and at the same time can speculate the position of the shaping mirror at night. I will introduce to you how the corneal topography map guides the fitting of orthokeratology. The basis of the corneal topography of the placido disc is the reflection of the concentric rings on the cornea. Simply put, the projection of the placido disc on the corneal surface can be used to calculate the shape of the corneal surface through the distribution of these placido discs on the corneal surface. On the corneal topography, the closer the concentric ring spacing, the steeper the corneal curvature; the farther the concentric ring spacing, the flatter the corneal curvature. However, the result of the corneal topography we see is not the shape of the cornea itself, but the shape of tears formed on the surface of the cornea. Therefore, when making corneal topography, we must ensure that the tear film on the cornea surface is complete and smooth, so that a more accurate corneal topography can be made. There are several modes of corneal topography: the first type of axial map (Axialdisplaymap), generally fits the surface of the cornea at the center of the cornea more accurately, but for the surrounding cornea, it is not very accurate. The second type of tangential display map (Tangentialdisplaymap), which is closer to the true curvature of the cornea, is also commonly used when fitting corneal orthopaedics. The third type of elevation map (Elevation display map), which can reflect the shape of the real corneal anterior surface, can be divided into an absolute height map and a relative height map.

Dr. Wang Kai personal experience | Answers to questions related to full femtosecond surgery

The purpose of writing this article is to make science popularization for friends who plan to perform myopia surgery and are suitable for full femtoseconds. I have done a lot of refractive surgery in the past few years, and I myself underwent full femtosecond myopia surgery three years ago and successfully removed my glasses. Therefore, I would like to start from the dual identity of a refractive surgeon and a patient after full femtosecond surgery, and talk about several issues of vision recovery after full femtosecond surgery. 1. The “white haze” myopia refractive surgery in front of the “lens” is different from cataract surgery and fundus surgery, because patients have different expectations for surgery. The latter can be said to “send charcoal in the snow” to help patients solve the hidden dangers of blindness and keep the patients’ eyes bright; while the former is “improving the icing on the cake” in order to pursue better visual quality and free patients from the shackles of glasses. So my patients with myopia surgery often report to me: “Doctor, I have a week after surgery, and my vision has reached 1.2. Why do I still feel hazy when I see things? Is there something wrong with the surgery?” This question involves Quan Fei. The operation principle of second myopia surgery: it is a process of using a full femtosecond laser to pre-scan the corneal stroma layer to separate a “convex lens”, and then manually separate and remove the “convex lens” through a small incision of 2mm~4mm. After the “convex lens” is taken, the upper and lower layers of the cornea must be adhered and healed together, which requires a process. Before it fits perfectly, the “white fog” in front of the eyes is very common. Just like a fog in front of the camera lens, everyone’s “white fog” disappears at a different rate. Young people (such as those in their 20s) There may be no “white fog” in three days. If you are older (in your 30s or 40s), it may take three weeks for the white fog to disappear. 2. The speed of vision recovery speed In addition to the problem of “white fog”, the optimal time of postoperative vision is also different. The vast majority of people may achieve vision of 1.0 or more on the first day after surgery; however, there are also individual patients, such as me, who have vision of 0.6 and 0.8 on the first day after surgery, and have arrived after more than 3 months or even nearly half a year. 1.2. Therefore, if the dioptric power of the surgical design is no problem, the surgical process is smooth, the laser scanning is very smooth, and the recovery of vision is generally only a matter of time and individual differences. Don’t worry. Figure 1. Schematic diagram of the principle of full femtosecond myopia surgery. 3. Dry eye and night vision quality problems In the early stage after corneal surgery, due to laser cutting of the cornea, a small amount of nerve plexus structure regeneration takes a period of time. Most patients will have dry eye phenomenon, which will generally recover gradually within six months. More artificial tears can effectively relieve. In addition, due to changes in the corneal refractive index in the surgical treatment area, there will be night glare and dark vision decline in the early stage. Night glare and dark vision decline will alleviate or disappear from 3 to 6 months after surgery. Some dark pupils have large The patient may continue to exist, but it will alleviate over time; looking at the phenomenon of “ghosting”, “flower eyes” and visual adjustment functions in the vicinity, it will take three days for the young people to recover quickly, and the people in their thirties or forties may be slower. It takes 3 weeks to a month. This is related to the visual adjustment function and can generally be restored. In addition, patients do not need to cover their eyes alternately to compare which vision is clearer. In the period of vision recovery, it is meaningless to compare monocular vision-take my own example, my main eye is the right eye, but the left eye can be early after surgery Obviously clearer than the right eye; but after half a year after surgery, the right eye has better vision than the left eye. Therefore, the recovery speed of the eyes may also have a sequence, do not rush. 4. How to treat the hidden complications of myopia surgery Whether it is full femtosecond, half femtosecond or superficial surgery, it belongs to corneal laser surgery. The most serious long-term complication that doctors worry about is secondary keratoconus because of this Once complications occur, the consequences are serious. However, the technique of myopia surgery is very mature, and the probability of secondary keratoconus has been reduced to a very low level. Preoperative examinations will try to exclude the risk of such complications and ensure that the residual thickness of the cornea is safe enough. No surgery is absolutely safe and perfect. It is also unrealistic to completely avoid such complications. Myopia surgery is ultimately a matter of personal choice. If you choose not to perform surgery, you should wear glasses honestly. Despite the inconveniences associated with myopia, it can be accepted; if you choose to perform surgery, go to the professional ophthalmology department to check according to the process, after the evaluation result is appropriate, find an experienced refractive

Myopia Science Essay

With the advent of the information age, electronic products are constantly pouring into our lives, and the age of myopia is increasing year by year. In addition to paying attention to the prevention and control of myopia in children and adolescents, more and more adults have good vision “The requirements are getting higher and higher. The daily requirement is not only to see, but also to see clearly, comfortably, and even beautifully. So for myopia, the first thing we want to emphasize is “prevention”, try to keep outdoor activities accumulated for more than 2 hours per day, let our eyes fully “eye bath”, follow “20 (20 minutes)-20 (20 Feet, about 5 to 6 meters)-20 (20 seconds)” golden rule, these can be simple and effective as a daily eye protection method. Of course, for people who have developed myopia, it is especially important to find regular medical institutions for “intervention” in time. Try to prevent yourself from developing into high myopia, because the risk of fundus diseases in high myopia will increase significantly. Regarding correction methods for refractive errors, there are non-surgical correction methods and surgical correction methods. As a non-surgical correction method, frame glasses are durable. In addition, there are contact lenses (soft lenses, rigid oxygen-permeable contact lenses (RGP), orthokeratology lenses). Children and adolescents can generally control the development of myopia by wearing orthokeratology lenses (about 70% effective). At present, the use of 0.01% atropine eye drops has also become one of the methods for children and adolescents to control myopia, with an effective rate of about 50% to 60%. Surgical correction methods mainly include corneal refractive surgery, intraocular refractive surgery, and scleral refractive surgery. For some people who have a desire for lens removal, they can go to a qualified ophthalmology hospital for a preoperative professional evaluation to decide whether they can undergo surgery because Each surgical procedure has different indications and contraindications. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.Important: why there is no way to cure myopia that has occurred! ! !

After myopia surgery, is the corrected visual acuity above 1.0?

Question 1: Will my vision “bounce” after myopia surgery? To answer this question, let’s start with the cause of myopia. Myopia is generally too long, and the light is only focused in front of the retina, not on the retina. This causes myopia to blur distant objects, and myopia surgery is Find a way to let the light fall on the retina. &nbsp. There are two main parts of the eye that can change the angle of light refraction. One is the lens and the other is the cornea. Currently there are two main types of myopia surgery, one is ICL lens implantation and the other is laser correction surgery. It acts on the cornea, mainly in full femtoseconds and half femtoseconds. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb&b The principle of surgery is to use a laser to polish the cornea to make the corneal curvature flat and allow the light to refocus on the retina. The polished part is the stroma of the cornea, which cannot be regenerated. &nbsp. Speaking of which, you should be able to understand that since the regeneration is not possible, the corrected power is generally stable. It can also be said that the correction of myopic power by laser correction surgery is one-time, and there is no possibility of retreat. &nbsp. Generally speaking, the structure of the adult’s eyeball is mature, and the degree of myopia will basically stabilize. Some people may have myopia surgery, and their vision may drop again, but this is not the “pot” of myopia surgery itself. It may be that myopia is caused by excessive eye use after a long period of time. &nbsp. So after myopia surgery, if you want to keep the effect, you should follow the doctor’s advice and cultivate good eye habits. &nbsp. Question 2: Why should myopia surgery be done after the age of 18? &nbsp. The better period for myopia surgery is roughly 18-50 years old. The ophthalmologist will evaluate the myopia patient’s own specific conditions and adjust the treatment age range appropriately, but generally will not advance the age range of myopia correction surgery. &nbsp. Since the age is less than 18 years old, people’s eyeballs are still in the period of growth and development, and surgery at the developmental stage often has little effect. Even if the operation itself is highly completed, there is still a high probability of visual regression after surgery. &nbsp. Premature surgery not only affects the degree of vision recovery, but also affects the future development of the eye and the structure of the eyeball. &nbsp. Question 3: Is there a risk for myopia surgery? Objectively speaking, there is no zero-risk medical behavior, as is myopia surgery. &nbsp. First of all, it is necessary to know that myopia surgery is contraindicated. Not everyone can perform myopia surgery. For example, patients with uncontrolled glaucoma, keratoconus and other eye diseases are not suitable for myopia surgery. &nbsp. Secondly, if you want to control the risk, the key is to choose the operation method that suits you. Different myopia operations have a suitable population. For example, in patients with myopia whose cornea thickness is relatively thin, it is not possible to achieve a safe corneal thickness range after laser cutting, so ICL lens implantation should be considered. &nbsp. These must go through a comprehensive and rigorous preoperative inspection to ensure that accurate and sufficient information is collected for doctors to evaluate to determine whether myopia surgery can be performed and which surgery is suitable. &nbsp. In Kunming Eye Hospital, there are more than 20 preoperative examinations for myopia surgery. The basic examination items include: ophthalmology examination, intraocular pressure examination, corneal topography, corneal thickness, anterior chamber depth, mydriasis, scanning laser fundus examination, Fundus examination under the slit lamp, strabismus measurement, tear secretion, etc., ensure safety and controllable risks. &nbsp. Question 4: After myopia surgery, the corrected visual acuity is more than 1.0 after surgery? Outpatients often have such patients asking: “Since I have spent money on surgery, I have to have a postoperative vision of 1.5. Seeing it clearly, can the doctor do it for me?” &nbsp. I believe that many people will also have this idea, that the higher the postoperative correction of vision, the better. &nbsp. In fact, in general, postoperative corrected vision depends on the eyes

How to protect eyes scientifically in daily life

Now that myopia has become a problem that troubles all parents and friends, how can we improve myopia? In addition to medical correction methods, daily care is also particularly important. The most important thing is to look at the normal close distance and 45 minutes, and look at it for about ten minutes. It is best to guarantee more than two hours a day. If you can’t guarantee outdoor activities, at least make sure to stand in front of the window and watch from a close distance with your eyes. At the same time, you must keep doing eye exercises, at least 1 or 2 times a day. In daily life, you must Use your eyes correctly, including the posture of writing and reading. Your eyes must be a foot away from the book, your chest should be punched from the table, and your sitting posture should be upright. The light of reading is also very important. You must study in moderately strong and dark light. , Reading books is also very harmful to the eyes. In addition to these aspects, we must also ensure our balanced diet. Usually eat more vitamin-rich foods, such as carrots, blueberries, tomatoes, corn, etc., to the eyes A certain benefit, another one is myopia to more than 300, it is best to wear glasses all the time, if it is below 300 degrees, you can’t see clearly, you can wear your daily life when you are on the blackboard, you don’t need to wear it, protect your eyes Fight for the night!

I heard that myopia surgery is easy to cause inflammation in summer?

Question 1: I heard that myopia surgery is easy to cause inflammation in summer? A friend left a message saying that I saw it on the Internet: it is hot in summer and sweats a lot, and it is easy to cause wound inflammation, so it is not appropriate to perform myopia surgery in summer. Is this true? &nbsp. First of all, both laser correction surgery and ICL crystal implantation are minimally invasive surgery, which can be performed only with local anesthesia. The incision is small, the recovery is fast, and it is not affected by the season. &nbsp. In the case of full femtosecond surgery, the surgical incision is only 2-4 millimeters, and the actual laser time on the operating table may be more than ten seconds. &nbsp. Secondly, myopia surgery will have a series of measures to reduce the risk of hidden eye problems from preoperative to postoperative. &nbsp. A series of standard inspections before surgery, including the possibility of screening for eye diseases. If there is inflammation or inflammation of the eye, it will generally be treated first. Before the operation, the doctor will also let the patient drop eye drops to further “disinfect and disinfect” the eyes. &nbsp. Moreover, regular eye hospitals also have very strict disinfection regulations for operating rooms and procedures, and follow the doctor’s instructions after surgery, and it is generally not easy to cause inflammation and other problems. &nbsp. Question 2: Myopia surgery when I was young, would I be blind when I was old? Is it true that “myopia will cause blindness in myopia surgery, or cause cataracts, glaucoma and other eye diseases”? Is it true? &nbsp. Will you be blind? Let’s start with the principle of myopia surgery. Take laser correction surgery as an example. It polishes on the stroma of the cornea. Think of the eyeball as a basketball. Laser correction surgery is equivalent to the ball. The surface is scratched and has no effect on the bladder. &nbsp. It does not touch the deeper tissues of the eye, nor does it change other eye structures, which means that the surgery itself does not have the conditions for blindness. &nbsp. As for myopia surgery, aging will cause cataracts and glaucoma and other eye diseases. It is even more nonsense. When people are old, they will suffer from blinding eye diseases such as cataracts. It is generally due to age, which leads to lens degradation and surgery. It has nothing to do with itself. &nbsp. Q3: After myopia surgery, will the baby drop off? As mentioned above, myopia surgery does not go deep into the retina. The surgery itself will not cause retinal detachment. Whether it is laser correction surgery or ICL crystal implantation, it will not affect the normal delivery of pregnant women. &nbsp. The true cause of retinal detachment is high myopia (greater than 600 degrees). The abnormal growth of the eye axis of patients with high myopia causes atrophy and other degenerative diseases such as atrophy of the retina and other tissues. The vitreous changes from colloid to liquid, and liquid substances pass through the retinal hole Entering the back of the retina, under the action of gravity to produce traction on the retina, it is easy to cause retinal detachment or perforation. &nbsp. Question 4: Ophthalmologists do not perform myopia surgery themselves? In fact, whether or not to perform myopia surgery is an individual’s choice of subjective will. Although the current myopia surgery has developed very mature, but the personal willingness to remove the lens is still a major factor. &nbsp. Second, myopia surgery is not for everyone. With the idea of ​​performing myopia surgery, the first thing to do is preoperative eye examination to see if it meets the surgical conditions. Only those who meet the conditions can perform myopia surgery. &nbsp.Ø&nbsp. Who can perform myopia surgery? &nbsp.1. Myopic degree is above 50 degrees 2. Age between 18-50 years old 3. 2. The diopter has been stable in the past two years (the development speed is no more than 50 degrees per year) 4. 4. Those who wear invisible eyes will be inspected and operated after stopping for 1 week with soft mirrors, and for 1 month with hard mirrors No active eye disease 6. No systemic metabolic diseases 7. I have the desire to take off my glasses. Also, if the doctor has myopia surgery, it is impossible to judge from the appearance alone, right.

Low dose atropine for myopia

Now low concentration of atropine (0.01% atropine) is very common in the treatment of myopia in children. However, 0.01% of atropine is not listed in China. Its practical high-concentration and low-dose atropine treatment is also very effective. I have also been using 1% atropine to treat myopia in children. Age: 5-13 years old myopia range&nbsp.50°-300°Routine ophthalmological examination before treatment, exclude glaucoma, corneal disease and other diseases and contraindications that affect vision. Usage: Eye drops once a week. It is generally recommended to use it after school on Friday during school. The pupils will dilate after medication and rest at home on Saturday and Sunday. This will have little impact on learning and life. I basically got used to it on Monday. The next few days will have little effect. Review once a month. Can persist for several years. &nbsp. Many examples have been used in this way, and the results are good. Some eyesight returned to above 5.1. The degree of myopia is significantly reduced. &nbsp.&nbsp.13 years old and above, myopia time is longer, myopia degree is higher, generally no method. I have written several times to share on Weibo

Myopia and prevention-everything you need to know is here!

Introduction: Myopia is divided into simple myopia and pathological myopia. Pathological myopia is a pathological ocular disease of the fundus and will not be discussed here. Simple myopia is divided into middle and low myopia (below 600 degrees) and high myopia (above 600 degrees). The causes of myopia are divided into two categories: genetic factors and environmental factors. Environmental factors are currently known mainly for close work and study. The genetic factors that cause myopia are not important because they are inevitable and only for understanding: the main evidence of genetic factors for myopia includes family aggregation and ethnic differences (the highest incidence of yellow races, followed by Caucasians, and black races) . Environmental factors include: 1. Short-distance work: Evidence of scientific research transfer: The incidence of myopia in elderly people with a significant number of years of study has increased significantly. For the elderly who read and write daily, the incidence of myopia and the degree of myopia of students increased significantly. For occupations requiring close-range work, the number of myopic people has increased significantly. The incidence of urban myopia is much higher than that of rural areas. 2. Form deprivation: in children and adolescents, during visual development, due to various reasons, such as congenital cataract, congenital ptosis, corneal scars, etc., blocking external light from entering the eyeball, leading to amblyopia and form deprivation myopia occur. 3. Nutrition: The relationship between nutrition and myopia is quite controversial. Some scholars believe that vitamin deficiency can cause myopia, such as vitamin A, vitamin D, lack of animal protein in food can cause myopia, and sweets can increase the incidence of myopia. 4. Systemic and eye diseases: tuberculosis, syphilis, childhood febrile diseases (such as measles, etc.) and infection lesions (sinusitis, tonsillitis), etc. may be related to the occurrence or aggravation of myopia. Summary: The above factors are only a summary that may cause myopia. The causes of myopia are complicated. It is still in the research stage and is only for the reference of parents and friends. To avoid the occurrence or aggravation of myopia, the best and most accurate method is: 1⃣️reduction Time to use your eyes at close range, rest for 30 minutes with your eyes at close range for 10 minutes. 2⃣️ Ensure sufficient light when working and studying at close range. 3⃣️ Balanced nutrition, eat less sweets. 4⃣️ Timely detection of false myopia, active treatment to avoid the occurrence of true myopia, or after the occurrence of true myopia, actively seek help from an ophthalmologist to avoid rapid progression of myopia.

Paradox of the pricing of myopia surgery

I often see the price list of myopia surgery in many private hospitals, which can be described as dazzling and dazzling. Take the LASIK price list of a private hospital as an example: corneal topography/aberration guided LASIK of Zeiss femtosecond combined with the latest model of Amax, 20,800 yuan/binocular Zeiss femtosecond combined with the aberration mode of the latest model of Ames LASIK, 17800 yuan / corneal topography / aberration guide LASIK of the latest model of Amarus femtosecond combined with Amarus, 19800 yuan / aberration mode LASIK of the latest model of LASIK, amalgamated by the latest model of Amaze Binocular eagle vision femtosecond combined with eagle vision excimer Q value guidance LASIK, 14300 yuan / binocular eagle vision femtosecond combined with eagle vision excimer aberration optimization LASIK, 13300 yuan / binocular Intralase femtosecond merged eagle vision excimer Q value guided LASIK, 11800 yuan/Binocular Intralase femtosecond combined with eagle excimer aberration optimization LASIK, 9500 yuan/binocular. Is it dizzy, is it dizzy? The price chaos gradually attracts charming eyes, I don’t know which one is suitable. I believe that no matter which myopic patient arrives at the hospital, his head will be big, his scalp numb, and he will be taken away. Don’t panic, let me analyze it for you. Through such a price list, we first know that this hospital is still quite powerful and local, with a full set of refractive surgery equipment such as ZEISS, Eagle Vision, Armas, Intralase and so on. Unlike some private hospitals that apparently have only one set of equipment, they list the price list of three sets of equipment, and they are clearly fooling people. Don’t you be fooled by your wealth? No, it may be even worse. If you want me to say that if a doctor is serious and responsible, and can eat the temper of every device, the aberration optimization LASIK at the price of 9500 can fully achieve the same effect as the 17800 aberration mode LASIK, because one is Amax Aberration optimization, one is the aberration optimization of Eagle Vision equipment, the only difference is that the flap making equipment is different. The same two Q-value guided operations are also different in valve making equipment, and the other are the same, but the price is 11800 and 14300, and the latter is not necessary to spend 2500 more. Speaking of which, it’s true that the refractive surgery is worth the price and the price is the same. As the saying goes, clever women can’t cook without rice. If the equipment is limited, it is really stretched. But there are too many devices and there are also troubles. Because each set of equipment can be operated correspondingly, how should it be priced? It can’t be the same, can’t explain it? As can be seen from the price list, the price setter has divided several brands into three, six, and nine in accordance with the mentality of the Chinese. For example, the latest models of Zeiss and Amers in Germany are the first, the German Eagle is the second, and the American Intralase is the third. Then there is the ridiculous price ladder above. I once wrote a comparison about the femtosecond platform, if you are interested, you can take a look. Department of Ophthalmology Dr. Zhao Wei: Nanojoule femtosecond, aerospace femtosecond, carved green femtosecond, 3D full femtosecond, silly and unclear-Femtosecond platform comparison is completely different due to femtosecond valve control , But why was it used by merchants to harvest leeks? The blame is only on the mentality of the Chinese, not seeking the best, but seeking the latest and most expensive. This is also the price people pay for pursuing vanity. One of the most critical paradoxes of surgical methods is, how do you know whether you should do corneal topography-guided surgery, Q-value guidance, or aberration optimization? As can be seen from the price, topographic map guidance>Q value guidance>aberration optimization. According to the logic of the price maker, that is to say, topographic map guidance is the best and aberration optimization is the worst. In fact, it is the same. From the three surgical methods, the degree of personalization is the highest, and the remaining two are reduced in turn. That is to say, the first kind is more tailor-made, the second and the third kind are standard operations, and the degree of personality is low. Of course, if you are suitable for the first kind, then of course suitable for the other two. As a result, when you arrive at the hospital, there will inevitably be a sales nurse who will advertise the benefits of the most expensive one. To put it bluntly, such a large surgery price list is actually for the first surgery. Of course, as far as you choose which kind of surgery to do for you first, the two say

Can’t read the computer optometry list? Don’t worry, the ophthalmologist teaches you the skills in 3 minutes

Do you feel the same? I believe that many parents with children have a deep understanding that the end of the annual holiday is a big visual test for their “little beast”. “Check the light, see if there is myopia, hyperopia and astigmatism.” It has become a “mandatory question” after many children’s holidays. However, many parents feel that the big head is not only to take the children to check their eyesight, but also that the refractory list after the check is only a few letters, a few mathematical symbols and Numbers, what it feels like it’s like the Morse code, you can’t understand it and you don’t know what the child’s eyes are. Don’t worry, Dr. Ophthalmologist takes you to unlock the optometry list in 3 minutes! What does the data on the computer optometry list stand for? When you get a computerized optometry list, the general distribution should look like this: there is the examination time, patient-related information and relevant examination data. The information at the top of the optometry sheet is often the date and time, the examination number and name information (may also be a number) of the child’s examination. This is a very basic thing, and most parents can understand it. Next I will give Everyone talk about dry goods, it is recommended to take a small book to write down! 1. Vision: In the R(Right) and L(Lift) optometry sheets, R(Right) represents the right eye, and L(Lift) represents the left eye. Below R(Right), it is related data indicating the vision condition of the right eye, and below L(Lift) is the related data indicating the vision condition of the left eye. 2. Refraction: SPH, CYL, AXSPH (S) stands for spherical lens, which means myopia or farsightedness (“+” means farsightedness; “-” means nearsightedness; “number” means the corresponding value). CYL (C) stands for cylindrical lens, which means astigmatism (“+” means farsighted astigmatism; “-” means nearsighted astigmatism; “number” means the corresponding value). AX refers to the axis of astigmatism ↓↓↓ In order to deepen everyone’s impression, we will further understand through this report: ↓↓↓ The first picture: represents the right eye 275 degrees myopia, astigmatism 125 degrees, the axis of astigmatism is in the direction of 169 degrees . The second picture shows the child’s left eye myopia is 175 degrees, astigmatism is 175 degrees, and the axis of astigmatism is in the direction of 171 degrees. 3. Other data: VD, PD, OD, and OSVD12.0 represent the lens distance, PD64mm represents the interpupillary distance; OD represents the right-eye vision, and OS represents the left-eye vision. 4. Common questions: Why are there four sets of data displayed under the left and right eyes? In fact, it is very simple, in order to ensure the accuracy of each measurement result, so each vision inspection will generally be performed on each eye. Three consecutive measurements, then based on the measurement results, calculate the average value as the test result for evaluation, that is, the bottom set of data. Can I read the optometry list now? Don’t worry, let’s go back and look at the first computerized optometry list. Use this list to test whether we have the ability to read computerized optometry lists. First look at the situation of the right eye: right eye 250 degrees myopia, astigmatism 150 degrees, astigmatism axis in the direction of 5 degrees. Look at the situation of the left eye: myopia 350 degrees left eye, astigmatism 225 degrees, astigmatism axis is located in the direction of 180 degrees. Comprehensive diagnosis: The child has myopia and astigmatism problems. Myopia in the right eye is 250 degrees and astigmatism is 150 degrees. In the left eye, myopia is 350 degrees and astigmatism is 225 degrees. How is it? Is it easy to see the computer optometry list now? Haven’t read it yet? It doesn’t matter, leave a message below, send me the specific situation of the child, I will help you answer it in detail online! Don’t rush away, the key point about the child’s optometry has not been finished! The child optometry, why do ophthalmologists recommend going to a professional institution or hospital? Most parents see that their children have vision problems, so they quickly take their children to check their vision. But where should I check? Some parents think that it doesn’t matter where they go, so they may choose a general eyewear store on their doorstep. However, what these parents do not know is that most of the general optician shops near the community do ordinary optometry instead of professional medical optometry, which can easily lead to inaccurate children’s degrees and mismatched mirrors. For example, a child who was originally myopic at 250 degrees may wear 300-degree glasses because of an inaccurate examination. If the child wears glasses that are not suitable for a long time, not only can the child not correct the vision, but the degree of myopia will increase faster. Ophthalmologists have always recommended that parents find that their children have vision problems, and try to take their children to a professional medical institution for inspection. This is the reason! So, ordinary optometry and

Why is the effect not good after the second synergistic operation?

This is a more tragic question. Patients who encounter this kind of thing can be said to be more difficult and more sad. “Who is worse than me?” The person who did not perform well after the first myopia operation was very painful himself, and he had to endure the consequences of poor visual quality while suffering psychologically. I have seen such a person, and everyone around him thinks he is crazy. People who have experienced an unsatisfactory operation will have more or less mental and physical problems. But there must be a cause for the accident. There is no love for no reason, no hate for no reason, and no patient who complains for no reason. I always think that those who feel that the postoperative effect is not good, and the result went to the surgery hospital or the surgeon, and the result was no problem, everything was answered well, not a trusted hospital, not a reliable doctor, or a doctor May not achieve the ability to solve problems without making mistakes or finding problems. If the doctor who gave you the first surgery didn’t do well in the first operation, it is very nervous to have the second surgery done by him. On the contrary, for a doctor who can do the second synergistic operation, his first operation must be very reassuring. The second operation is not effective, and choosing the same doctor in the same hospital may be a taboo. Secondly, the second efficiency surgery is not a separate operation. In the strict sense, there are many ways to have multiple laser devices. Each laser device will have a corneal topography guide and a general aberration guide method. To be honest, it is difficult for a refractive surgeon to master the skills of the first operation to ensure perfection as much as possible, not to mention the second increase. The operation is effective. It is said that a doctor can perform thousands of initial operations a year, but the second synergistic operation may not encounter a case for half a year. Practice makes perfect, practice shows the truth, so small number of cases also determines that it is difficult for doctors to gain experience from it, and make a second operation to the extreme. Third, if you use the wrong method and design the wrong plan for the second synergistic operation, it will definitely not work well. I remember that some doctors still use standard methods to increase patient efficiency. In some cases, the light area of ​​the second surgery is too small, or it is seen that the literature uses full femtoseconds to perform the second surgery, and ICL is used to perform the second synergistic surgery to solve myopia combined with corneal astigmatism. The result can be imagined. Fourth, it is still a question of expectations. Patients who perform poorly at the initial surgery often have high expectations. For this patient, the same is true for the second operation. Sometimes despite improving eyesight and improving the quality of vision, the doctor thinks that I have tried my best. You see, your glare, halo and night vision have been greatly improved. But the patient was still not satisfied. Just like some cosmetic surgery patients will go on to the point of non-stop cosmetic surgery and want to stop. I hope that every patient who wants to perform myopia surgery will not have problems, and even if there is a problem, do not rush to perform a second operation. If you want to perform second-efficiency surgery, you must find a reliable center and doctor for a comprehensive examination and evaluation. It is best to find a variety of expert consultations and listen to various suggestions. Finally, you need to understand the feedback of patients who have done this surgery. Finally make your own decision. But one thing, using painting as an example, the second synergistic surgery is definitely not to solve the process of restoring a bad painting to a blank paper, but to correct the wrong color and the strokes in the wrong position. Some paintings are easy to repair, while others are difficult. Even if they are repaired, they may not meet the requirements of collectors. Because, everything cannot be repeated.

Is it difficult for people with high myopia to have love?

This is a matter of knowledge. My answer is: “Even my own descendants will be affected.” My answer is very simple, because I always like to answer questions about Zhizhi in a simple and rough way. This answer makes someone very disdainful, or very disagree with my statement, commenting that my answer is not as good as a layman. Today we will talk about this high myopia problem. In fact, the implication of my answer is that high myopia may also affect the marriage problems of future generations. I don’t know what the comment means, maybe the level is limited and I don’t understand Either stepped on his tail, he is a high degree of myopia, so the answer to me is unfair. My answer has two meanings: First, high myopia can certainly have love, as for easy, not easy, it depends on the nature. In theory, high myopia is disadvantaged in the process of competing for spouses in terms of survival rules. Second: Because of the high probability that high myopia will be inherited, its children are also likely to be high myopia, so they will also encounter the same problems as their parents on the road to love. I remember seeing an American movie “One Thousand Hairs”. The story is about the future world. Genes determine fate. People with perfect genes become the mainstream of society, while natural humans with imperfections are reduced to the margins of society. The male protagonist is such a person with imperfect natural genes. Since his birth, his natural genes have determined his myopia, lack of height, and heart disease. He can only live to 30 years old. And his only dream is to wander into space, but imperfect genes prevent him from realizing his dream. For this dream, he corrects his vision by wearing stealth, interrupts the lengthening of his leg bones and improves his height, and carefully cleans the dandruff hair every day to ensure that he does not expose any clues. Finally, he successfully mixed into the inspirational story of the shuttle. Although it is a science fiction movie, it tells the truth. People are born with different genes, some are tall, some are short; some are black, some are white; some are beautiful, some are ugly; some are either nearsighted, farsighted, or astigmatism, and some People have perfect corneal shape and vision, and they are not short-sighted despite how they misuse their eyes… do you say the world is fair? It is indeed unfair, but this is the law of nature-genetic polymorphism determines the survival of the fittest, survival of the fittest, natural selection, so as to ensure that life continues to progress and humans dominate the world. Theoretically, if any genetically deficient organism does not adapt to this world, most of it will be eliminated. For example, a short giraffe will starve to death because of insufficient food; a gazelle that does not run fast will be the first to be thrown down by a lion; an eagle with poor eyesight must be the first to starve to death… So, the giraffes we see are all with long necks, the gazelle are especially capable of running, and the eagles are all good hunters who are well aware of the problems. Nature is fair and cruel, and the last laughs are the excellent genes that win with life. The same is true of humans. In fact, at the time of embryos, embryos with bad genes have already spontaneously aborted. For those human beings who were born in luck, such as people with leukemia, heart disease, and Down syndrome, if a problem is found before birth, the general hospital will also recommend induction of labor. Because even if you do not induce labor, you will die of illness after birth. And those who are genetically ill after birth, of course, generally cannot survive the childbearing age, so there will be no offspring. And those who are fertile, but because of the difficulty in survival and spouse selection, are weaker than those who are healthy, thus ensuring that the bad genes will gradually die out, and the excellent genes will be retained. To give a simple example, for example, the bureaucrats of the dynasties were expensive, the relatives of the emperor and the relatives were generally beautiful and handsome. why? Because this kind of people are often right in marriage, beautiful men and women. Therefore, a good appearance gene is guaranteed. On the contrary, in a wild place, it is often difficult to see beautiful boys and girls. I used to watch movie novels in the past and often said that in the remote villages of certain ethnic minorities, I often see beautiful women with beautiful national fragrances. Now think about it, it’s all a joke. Excellent genes can’t be continued and selected. How can a beautiful woman appear? Therefore, when we reach the place where ethnic minorities gather, your mentality must fall. Having said so much, I just want to say that high myopia, including congenital high myopia and acquired myopia, has genetic problems. Correct the commenter’s point of view, the height of the acquired is close

Are there any hobbies that prevent and control children’s myopia?

“Many parents read the article published yesterday: Does table tennis play a role in myopia prevention? Ask, if you want to give your child an interest class, is there any interest in preventing myopia?” ① 2 hours of outdoor activities during the day ; ② reading and writing to keep one punch, one foot, one inch and ③ 20-20-20 rule (20 minutes at a short distance to look at a distance of 20 feet, that is, 6 meters, 20 seconds away) is a “natural remedy” for the prevention and control of myopia. Therefore, the interests and hobbies that can satisfy the above three laws are all prevention and control of children’s myopia. &nbsp. One of the more difficult things to do is actually Article ②-Keep a punch and a foot while reading and writing. It is very difficult for children to maintain a good reading and writing posture. Once a bad posture is formed, it is difficult to correct it, and parents cannot supervise the child’s reading and writing posture at school. Therefore, this seemingly easy second item is the most Not easy to do (outdoor activities are relatively easy to do). &nbsp. Many children are using keratoplasty (or other methods) to control myopia, which is equivalent to the “antidote” of myopia, but poor reading and writing posture is the “poison” of myopia. Myopia control can not only use the “antidote” Without eliminating the effects of “poisons”. So correcting bad reading and writing postures (eliminating “poisons”) is important. &nbsp. Our clinic found that children who practice calligraphy, especially writing brushes, can maintain a good reading and writing posture: they sit straight while writing, and the angle of the head is relatively small. Therefore, if you want me to recommend a hobby, I would recommend training calligraphy for children-write brush characters! The reasons are as follows: when writing with a brush, the brush is required to be perpendicular to the paper (it cannot be written vertically, and the writing is not good), or even to “hang the elbow” (Figure 1), so it is easy to do “one punch, one foot, one inch”. For children, when writing with other pens, it is easy to “lie down” on the table, and the distance between the eyes and the book is far less than one foot (33 cm). It is easier to develop good reading and writing postures after practicing writing brush characters, and to maintain “one punch, one foot, one inch”. When forming good reading and writing postures, even when writing with a pen or ballpoint pen, it is easy to maintain the same as writing brush characters. habit. Figure 1 Posture when writing brush characters (pictures from the Internet)&nbsp. Writing brush characters in the title is one of the good interests that is beneficial to the prevention and control of myopia.

What is fast and slow mydriatic refraction?

“Why should mydriasis be mydriatic? What are the conditions for mydriatic refraction? What does fast mydriasis and slow mydriatic refraction mean? Should I use fast or slow mydriatic refraction? How about mydriatic medicine? How long does it take after taking the medicine? Effective, how long to recover? Does it affect the child’s eyes?-These questions are answered here. “One, why do mydriasis optometry? Children have a strong regulation effect, and different ages have different adjustment ability. The younger the age, the stronger the adjustment ability. In the process of optometry, if the tension or spasm is adjusted, the ciliary muscles cannot be fully relaxed and additional adjustments will cause interference to the optometry. In this case, the refraction result of myopia is higher than the actual (such as easy to wear glasses) Promote the progress of myopia), the refraction result of farsightedness is lower than the actual. Therefore, in order to obtain accurate diopters, children with refractive errors need to fully paralyze the ciliary muscles before performing optometry, which is what we usually call mydriasis optometry. Therefore, mydriasis is a side effect of optometry for ciliary muscle paralysis. Mydriasis can cause photophobia, tearing and other discomfort, which is an undesirable situation. Therefore, the expression of “mydriatic optometry” usually said is very inaccurate, it should be said “ciliary muscle paralysis optometry”. &nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&bb&nbsp.&nbsp.&bb The need for ciliary muscle paralysis optometry and precautions Generally, children under 12 years of age should do ciliary muscle paralysis optometry. In addition, the following conditions also require ciliary muscle paralysis optometry•&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Correction of poor vision or fluctuation of vision .&nbsp.&nbsp.Retinal retinoscopy results are unstable•&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.The difference between retinoscopy results and subjective refraction results is significant .&nbsp.&nbsp.People with obvious inclination or implicit inclination•&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Visual fatigue symptoms are not consistent with refractive errors &nbsp.&nbsp.&nbsp.&nbsp. High hyperopia or high astigmatism (high astigmatism is easy to cause adjustment fluctuations and unstable adjustment)&nbsp. In addition, also need to pay attention to: The younger the age, the stronger the adjustment, and the stronger the ciliary muscle paralysis agent needed. Generally children under the age of 8 need to use strong ciliary muscle paralysis agents, such as atropine. •&Nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Light-colored iris (Caucasian) races are more sensitive to ciliary muscle paralysis agents and require weaker paralysis drugs. •&Nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp.&nbsp. Pharmaceutical type: drops or gel eye drops, second choice ointment. Three, fast and slow mydriasis optometry-three kinds of ciliary muscle paralysis agents commonly used in clinic are ideal. The ciliary muscle paralysis agents used for optometry should have the following characteristics: 1. Fast onset; 2. Ciliary Strong muscle paralysis; 3. Less adverse reactions; 4. Rapid recovery; 5. It is better not to have a dilated pupil effect (at present, there has not been developed a ciliary muscle paralysis agent that only paralyzes the ciliary muscles but does not have pupil dilation) &nbsp. The ciliary muscle paralysis drugs commonly used in children in ophthalmology clinical work are all M-type choline receptor blockers, including

Why should the prevention of blindness and blindness start from the baby?

“Youth does not control near (look), the old comers are sad” read today a 2nd phase of big data research (6597 and 2579 respectively) at the University of Ophthalmology, Erasmus Medical Center, Rotterdam, The Netherlands Patients over 55 years old) report (Verhoeven, 2015). Participants underwent comprehensive eye examinations, including best corrected vision, objective optometry, fundus photography, visual field, and macular/optical disk coherence tomography (OCT). The researchers counted the cumulative risk and odds ratio (OR) of various types of refractive errors and low vision/blindness, and used screening information and patient medical records to determine the cause of visual impairment of low vision/blindness. &nbsp. Note: The WHO (World Health Organization) low vision standard is corrected vision between 0.3 and 0.05, and the blind standard is corrected vision less than 0.05. &nbsp. Several important conclusions are summarized as follows: 1. One third of patients with high myopia (≤-6.00D) are due to low vision and blindness caused by myopic macular degeneration (Figure 1). &nbsp. Figure 1 Myopic macular degeneration is the main cause of low vision and blindness in myopia above 600 degrees.&nbsp.2. The risk of low vision and blindness in the high myopia group above -10.00 is 22 times higher than other groups, -6.00D~ -10.00D 6 times higher myopia group (Figure 2). ——The higher the myopia degree, the faster the risk of visual damage increases. &nbsp. Figure 2 The risk of low vision and blindness in both eyes of high myopia&nbsp.3. The cumulative risk of visual impairment (low vision and blindness) in the high myopia group increases rapidly with age (starting at 60) (Figure 3). The older the age, the higher the risk. &nbsp.3 Cumulative risk of low vision and blindness in both high myopia, emmetropia and high hyperopia abscissa: diagnosis of low vision and blind age ordinate: cumulative risk of visual impairment&nbsp. Summary In all refractive errors, high myopia The most serious visual impairment is, the higher the degree of myopia, the faster the risk of visual damage increases, and irreversible myopic macular degeneration is the most common cause. Before the age of 60, the visual impairment of patients with high myopia is not obvious, and the visual damage (low vision and blindness) begins to explode rapidly at the age of 60. The way to avoid complications of high myopia is to control myopia, and only the time window of childhood can do myopia control. Therefore, parents should pay full attention to the problem of children’s myopia, young children emphasize prevention of myopia (delay the occurrence of myopia), school-age children emphasize control of myopia, and avoid the development of high myopia (Figure 4). People with high myopia will have a fairly long life cycle before the age of 60 is the “latency” of visual impairment, and will not show obvious visual problems. Because of the existence of a “latency period”, myopic patients can easily ignore and ignore risks. Refractive surgery does not reduce the risk of complications of myopia, but the popularity of refractive surgery will also mask the risk of a large number of patients with high myopia complicated by visual impairment. In the future, we should strengthen the eye health education for patients with high myopia who have undergone refractive surgery. It is estimated that the life expectancy of the generation after 00 in the future will reach 90, even over 100 years old. If the 60-year-old suffers visual impairment due to myopia complications (low vision/blindness), there will be 30 to 40 years of life that can’t be taken care of. It seriously affects the quality of life… and unlike cataracts (curable), macular degeneration is irreversible and incurable, so preventing blindness and curing blindness must start with the baby! &nbsp. Figure 4 Prevention of myopic visual impairment starts from childhood

What should I do if my child is short-sighted? The pros and cons of these 5 correction methods, an ophthalmologist comprehensive analysis for you

When children take kindergarten as elementary school, middle school as elementary school, and middle school as university element, they read and write too much, play piano at the critical stage of vision development, and high nearsightedness becomes inevitable. Myopia has become a major public health problem recognized by the world, especially the vision health of adolescents. Our youth myopia rate has reached as high as 50%-60%, and nearly half of the global myopia population is in China! A recent survey found that the myopia rate of Shanghai college students actually reached 95.5%, of which one-fifth was diagnosed with high myopia. We all know that high myopia can often cause blinding complications such as retinal detachment and choroidal neovascularization. Therefore, controlling or slowing the development of myopia is very important. Children and adolescents are in the stage of growth and development, and are the stage with the heaviest learning burden, and this stage is also the period where myopia develops fastest! Once myopia occurs, if it is not effectively controlled, there is a high possibility that the myopia degree will increase by 1.00-2.00D every year. Some scholars once called for the implementation of “93 academies” in the country: classes at 9 o’clock in the morning and school at 3 o’clock in the afternoon, without doing homework or playing with electronic products. But parents all know that this is difficult to achieve. Therefore, every winter and summer vacation, the ophthalmology clinics of various hospitals are always packed with anxious parents and ignorant children. I inevitably have to face the question of parents often: “Doctor Wang, is there any good way to control myopia? Nowadays, there are a variety of methods for controlling myopia on the market, which ones are effective?” “Is there any way to do it? It is better to control the degree of increase? It is best to lower the point…” The child is myopic. Since myopia cannot be cured at present, the most important thing for parents is how to control the development of myopia. Faced with the myriad of myopia control measures in society, parents often have no choice. Combined with the “Myopia Management White Paper (2019)”, today I will give you an analysis of several current myopia control methods that are more clinically effective: Method 1: Low-concentration atropine is found in randomized controlled clinical trials of 30 children’s myopia studies in the world. Glasses, atropine eye drops can significantly inhibit the progress of children’s myopia, and it is very effective! Especially when children start using low-dose atropine early, myopia can be better improved. The ATOM series of tests by the National Eye Centre of Singapore and the Institute of Ophthalmology of Singapore prove that the application of 0.01% concentration of atropine to control myopia in children, the 5-year average equivalent spherical lens progress is -1.38D; 0.01% concentration is 5 years compared to other concentrations of atropine. The length increases the least. Regarding the research of low-dose atropine, the most exciting discovery is to combine it with orthokeratology. As a combination therapy, 80% to 90% of myopia cases can be controlled, and only a low dose of atropine can only control 40%. It should be noted that although low-concentration atropine can effectively control the deepening of myopia, it cannot eliminate myopia. Moreover, atropine therapy should last at least 2 years. -Comprehensive evaluation-Recommendation: For children 6-12 years old with myopia development ≥0.5D in the past 1 year, 0.01% atropine can be used as the first-line medication to control the development of myopia. Advantages: effective, low cost. Disadvantages: some patients will have eye redness, foreign body sensation, difficulty in seeing near and fear of light after dropping the medicine; the effect on high degree is poor. Recommended index: ★★★☆☆ Method 2: Orthokeratology Orthokeratology is to wear a hard-breathable contact lens with special geometric design to make the curvature of the central area of ​​the cornea flat and regular in a certain range. Therefore, the reversible physical orthopedic treatment method for temporarily reducing the myopic refractive power and improving the naked eye vision. Why can orthokeratology control myopia? Many existing studies have found that orthokeratology can reduce peripheral hyperopia defocus, even improve the adjustment function of the human eye, and play a role in controlling myopia. If a child’s degree increases by 100 degrees per year, the correct increase in myopia may be reduced to 40-50 degrees per year after proper wearing of orthokeratology. -Comprehensive evaluation-Advantages: good effect, 40%~60% control effect Disadvantages: expensive, complicated fitting, long-term follow-up required. The requirements for lens care operations are high, and young children or children with poor self-care ability need parents to help care. Recommendation index: ★★★★☆Method 3: 2 hours of outdoor activities per day In 2017, a set of survey data from the World Health Organization showed that the rate of myopia among Chinese teenagers is 70%

Some considerations for myopia surgery

  Myopia laser surgery has strict requirements on the patient’s age, eye condition and physical condition, and not everyone is suitable for it. Therefore, you must patiently cooperate with the doctor to do a detailed examination before surgery. Preoperative preparation:   If you consider receiving refractive surgery, you must judge whether your basic conditions are met:   1, age 18 or older (special circumstances, such as high hyperopia, anisometropia, can be under 18 years old);   2, nearly two The diopter of the year is relatively stable (the diopter change is better than 100 degrees within two years);    3. There are no organic diseases of the eye, no active inflammation, physical health, no serious diseases, and mental health. &nbsp.&nbsp.&nbsp.   Intraoperative cooperation:   Operation requires patient cooperation. The degree of patient cooperation will play a very important role in the surgical effect. Generally, the following points need to be noted during operation:   1. The entire operation process should be enlarged Eyes, don’t blink at random, don’t turn your eyes casually.   2. When doing femtosecond laser to make corneal lens or corneal flap, relax and actively cooperate.   3. On the operating table, keep your hands on both sides of your body or in front of your chest. Do not touch the face disinfection area without permission. If you feel unwell, you can tell your doctor not to move around at will. &nbsp.&nbsp.&nbsp.  Postoperative instructions:   1. After the operation, the medicine should be used according to the doctor’s instructions to avoid eye trauma and prevent foreign matter from entering the eye. Try to avoid splashing water into your eyes when washing your face and hair. Do not apply eye makeup within 1 week after surgery.   2. It is still necessary to pay attention to eye hygiene after the operation, do not use eyes too tired, do not watch the computer, mobile phone and TV continuously for too long, do not play games.   3. It is recommended not to drive at night after the operation, and driving during the day is generally not affected.   4. Please do not swim within 1 month after surgery, try not to participate in basketball, football and other ball activities. &nbsp.
