A. LASIK sculpts the cornea, the front part of the eye. The cornea doesn't change much over the years, although there is a less than 5% chance you will need an enhancement/ touch up. LASIK, however, does not stop the natural/biological changes as we age from occurring, like cataracts or presbyopia. These changes will happen with or without LASIK and you may once again need some glasses correction to see your best.
