What is LASIK and how does it work?
LASIK is an acronym that stands for Laser in-situ Keratomileusis, which means to shape the cornea, using a laser. Using an instrument called a microkeratome, a thin flap of corneal tissue is folded back. The excimer laser is then used to precisely remove a predetermined amount of tissue from the inner cornea to correct the nearsightedness, astigmatism, or farsightedness. The corneal flap is then repositioned without stitches, and the eye is then operated on.
