If i get lasik eye surgery will i have perfect 20/20 vision and no longer need my glasses?

Potential, 4 awhile: Depending on your unique corneal variables ( astigmatism, level of myopia/hyperopia, corneal thickness, posterior corneal curvature) if all acceptable, then you have about an 95 to 98% chance to be out of your corrective spectacle/contact lenses. At least for awhile anyway. As you age, other factors enter the glasses freedom era, such as presbyopia, cataracts, corneal elasticity changes.
