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.
