Definitions for "LASIK"
See Laser Assisted In-situ Keratomileusis.
(LAY-sik): Acronym for LAser in SItu Keratomileusis. Type of refractive surgery in which the cornea is reshaped to change its optical power. A disc of cornea is raised as a flap, then an excimer laser is used to reshape the middle layer of corneal tissue, producing surgical flattening. Used for correcting myopia, hyperopia, and astigmatism.
Laser Assisted in-situ Keratomileusis combines the advantages of a skilled surgeon and the excimer laser. In this procedure, a microkeratome first creates a thin flap of tissue on the cornea. The flap is folded back and the laser gently sculpts the cornea, altering the shape to correct the curvature. The flap is returned to its original position, adhering without stitches. LASIK is a proven procedure for treating higher degrees of nearsightedness and astigmatism.
