There will be some risks, because this operation is irreversible and the thinned cornea will not grow back. The operation done five years ago cost 6200 yuan in Beijing 306 Hospital. I remember that there was a hospital called Runshi at that time, and the same expert was invited, only 4000 yuan. It is estimated that the doctor from 306 Hospital went to acupuncture. My sister did it at a colleague's place, and the effect was not as good as that of 306.

If it is high myopia, it is easy to form keratoconus because there is a gap in the middle of the cornea after operation. In that case, we can only change the cornea, but the chances are not great. As for the rebound, I have been doing it for five years, often staying up late, playing computer and video games, but my eyes are basically the same. I am 900 degrees nearsighted.

I think if you don't like beauty very much or your glasses are very high, you should wait. After all, this is irreversible. As a person who has experienced it personally, I will give you advice.
