It depends on each individual, most importantly the thickness of your cornea. LASIK works by ablating, or destroying, some of the inner layer of your cornea. By doing so, it effectively flattens the cornea and corrects your vision. The higher the prescription the more tissue needs to be ablated. So if you have a really high prescription and a thin cornea, LASIK would not be an option. There are a few other procedures that may be an option if LASIK isn’t. Go see your eye doctor and get more information.
