LASIK, an acronym for Laser-Assisted in Situ Keratomileusis, is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses.
Public information from the official LASIKFDA site:
"LASIK is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A knife, called a microkeratome, is used to cut a flap in the cornea.
A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced."
