The latest data from the Ministry of Education shows that in recent years, the overall myopia rate of my country's overall myopia has risen significantly, reaching 33%, which is 1.5 times that of the world average. It is particularly noteworthy that myopia has become a major public health issue affecting children and adolescents. The special survey carried out in 2020 shows that the overall myopia of children and adolescents in my country has reached 52.7%, of which about 35.6%of the primary school stages, and high school in high schools as high as 80.5%.

Summer is now "picking the tide" again

Over 80 % of high school students, many of them choose to perform myopia after the college entrance examination, so there will be a wave of "mirror picking" every summer vacation. The reporter learned in Beijing Tongren Hospital, which is good at ophthalmology that the number of myopia surgery has recently risen by 30%from the past, and nearly 100 average daily operations. Nearly 60%of patients are high school students who have just ended the college entrance examination and college students.

How many categories of myopia surgery? What is the difference?

What are the most common myopia surgery at present? Experts tell us that according to different surgery methods, myopia surgery is roughly divided into two categories.

One category is corneal laser surgery, such as full femtosecond myopia surgery, semi -flying myopia surgery, etc., through femtosecond laser or species laser cutting some corneal tissues to achieve the purpose of correcting myopia. Here we have to science the concept of femtosecond. The so -called femondo is a very small unit. How small is it? 1 Ferthlose is equal to 1 trillion -dollar seconds. Femittond laser is a laser emitted in the form of pulses, with only a few femtoseconds.

The other is crystal implant surgery. The crystals are implanted in the eyes through minimally invasive surgery, just like a pair of contact lenses implanted in the eyes.

What is femtosecond laser surgery? What are the characteristics?

Qi Ying, chief physician of Beijing Tongren Hospital's refractive correction center: It is characterized by a flying laser, one is short time, and the other is the space that works specially. So one is accurate, and the other is no damage to the surrounding tissue, so this is its advantage. The previous surgery (cornea) petals were made with a rotary knife to make a cornea, so sometimes the patients might be nervous, they did not cooperate well, or there was a problem with the quality of the blade, and some complications would occur. Flying laser, new technology, use it to make (cornea) petals, higher accuracy and higher safety factor. Another is that we can achieve personalized petals. We can follow the patient's eyes, such as corneal thickness and corneal flexion. Different people can choose different parameters, more humane and safer.

Is everyone suitable for myopia surgery?

In my country, myopia surgery has been applied for many years and is relatively mature technology, but can everyone take off their glasses in this way? Under what circumstances is not suitable for myopia surgery?

Medical staff reminded that myopia surgery has strict taboos, including unstable, suspicious or clear conical cornea, acute eye inflammation, and severe retinal disease. Diseases that affect corneal wound healing, such as severe scar constitution, diabetes, lupus erythematosus and other connective tissue diseases, are not suitable for myopia surgery.

Qi Ying, chief physician of the refractive correction center of Beijing Tongren Hospital: There should be no acute symptoms of eyes like rheumatoid diseases, or more severe eyes that affect vision eyes, or some retina's lesions. There is also a comprehensive inspection and system examination of the eyes. The thickness of the cornea, the (cornea) terrain diagram of the eye must meet the standards of surgery to perform myopia surgery.

Why should my myopia surgery from 18 to 50 set the age section?

Every summer, many friends who end the college entrance examination will perform myopia surgery. Why is it concentrated at this time? Because myopia surgery requires the lower limit of age, it is to be at least 18 years old, and there are also regulations on the upper limit of age. In the case of physical conditions, why is myopia surgery limited to age?

Qi Ying, chief physician of Beijing Tongren Hospital's refractive correction center: In fact, we basically set the age of myopia between 18 and 50 years old. It is relatively young and pays attention to beauty and exercise, so there may be some age, over 50 years old, he still has the needs of mirroring, and he can also do it, and he is a bit relaxed. The reason why we used to be 50 years old was because everyone knows that after 50 years of age, they are about to spend their eyes. If you look closely at the close distance, if you do the myopia, the flower eye will worsen or advance in advance, so you may have to wear a flower mirror immediately It is time to set this age. Under the age of 18 belongs to the period of physical development, the degree of children is not very stable, so this time.

Can myopia surgery solve myopia once and for all?

A surgery can take off the glasses, so it is not terrible at all, just go to the surgery. I believe many people will have such an idea. Will I never get myopia again after myopia surgery? Is there any possibility of rebound? Can myopia surgery really solve our eye disease once and for all?

Qi Ying, chief physician of Beijing Tongren Hospital's Quick Correction Center: In fact, myopia surgery is not once and for all. It is still necessary to remind everyone that our surgery is just a cure for you to take off your glasses. Therefore, there are some patients with high myopia, or possibility of pathological myopia. After the operation, he will still have some complications of the bottom of the eyes, such as retinal degeneration, crack holes, macular bleeding, so generally we postoperative postoperative operations after surgery. Patients will recommend that he three months, half a year, one year, and follow -up every year. The purpose of the follow -up is to check whether he has returned to his degree, and then one is to see if there are some complications like conical cornea. The most important thing is to check his eyes and see if there are some degenerations in the bottom of the eyes. It is not that the myopia is correct, and there will be no lesions in the eyes. Essence How to avoid vision after myopia surgery?

After myopia surgery, how to protect the eyes to avoid vision and return?

Qi Ying, chief physician of Beijing Tongren Hospital's Quick Correction Center: Generally, the first week after my myopia surgery is to keep the eyes from entering the water. In case of some dirty water, it will cause eye infection. Because the wound is not closed, the water cannot enter the water. Essence Another one is to use the eyes. In fact, the first day of the patient's vision was 1.0, 1.2 on the first day after surgery, it was normal, but we still don't recommend that he use his eyes too early, look at mobile phones, iPad, computers. One is because there will be a little dry and dry after surgery. If you use your eyes too early, it will be uncomfortable; there is another one. Although the end of the vision is good, sometimes you will have a little flowers when you look at it. You have to look at it hard. One is prone to fatigue, and there is one, and the degree may return. So within a week, we do not recommend excessive eyes.
