What should be paid attention to in laser correction of myopia? You must know
Sihaiwang: in recent years, the incidence of myopia is also higher and higher, and the trend is younger. After many young people get myopia, they will wear contact lenses for the sake of beauty, but some people think it's troublesome to wear contact lenses, so they go to do laser correction for myopia, but this operation can't be done by anyone. The following three conditions are met before they can be done.
All femtosecond laser surgery is a new method of laser surgery. Its advantages are: no flap, no knife, no pain, more safety and comfort. But like other myopia laser surgery, they have the following contraindications:
I. laser surgery for myopia can be performed only when the patient is over 18 years old
Professor Wu Junshu pointed out that the best age for myopia correction is generally between 18-50 years old. For teenagers under 18 years old, the cornea of the eyeball is in the development stage, the axial length of the eye is also growing, and the diopter is not stable, so matching lenses is still an ideal choice. In addition, the myopia degree and astigmatism degree of patients should be relatively stable, that is to say, the myopia degree in recent two years should not continue to deepen.

2. Operation should be careful if corneal thickness is not enough
In addition to the problems of age and myopic degree, if the patient has some autoimmune diseases, such as systemic lupus erythematosus, it is not recommended to have myopia surgery now. In addition, there are some patients whose eye conditions are not allowed, such as the corneal thickness is not enough, the diopter of myopia is more than 1000 degrees, and the cornea of the eye has a potential risk of keratoconus. For such people, Professor Wu Junshu suggests not to correct the refractive surgery.
3. Myopia surgery can only cure the symptoms but not the root causes
The vast majority of myopia is incurable, even if the excimer laser surgery is widely carried out at present, only a concave lens has been cut out in the corneal stroma of myopic patients, the myopia state of the eyeball itself has not been corrected, and there is still a risk of complications, so the key is to prevent myopia as soon as possible and delay the development of myopia.
To prevent myopia, it is best to reduce the time of continuous use of eyes as much as possible. When reading for 40 to 45 minutes, let your eyes rest for about 10 minutes in the form of looking far or closing your eyes. At the same time, use less video terminals such as computer and mobile phones. In addition, you can also strengthen outdoor activities.
