LASIK is a out-patient procedure intended that reduces dependency on eyeglasses or contact lenses.
LASIK stands for Laser-Assisted In Situ Keratomileusis and permanently alters the cornea, the clear covering of the front of the eye, using a highly specialized laser.
LASIK surgery addresses nearsightedness, farsightedness, and astigmatism. Bascially, an eye surgeon cuts a flap in the stroma, and then uses the laser to excise material under the flap. LASIK usually takes less than one minute per eye.
