The main added concern with LASIK for patients with high myopia is the risk of cornea thinning. This is because with the LASIK procedure, a cornea flap is cut first with the femtosecond laser before the doctor can proceed to correct your high myopia with the excimer laser. Due to the cut flap in LASIK, there is an added risk of corneal thinning.
You may want to consider the alternative no cut flap, surface-based “Trans-PRK” procedure. In TransPRK, there is no need to cut a cornea flap as the excimer laser vision correction is done on the surface. Instead of a cut corneal flap, a protective bandage lens is places on the surface to promote surface healing and removed after five days.
Thus, there is no concern about cornea flap complications and also less risk of cornea thinning.
