Lasik

LASIK is an acronym for Laser In Situ Keratomileusis. LASIK is another type of refractive surgery that uses a laser to reshape the cornea. Rather than removing the outer layers of the cornea like PRK, a surgeon performing LASIK first uses a special cutting instrument to cut a thin flap into the top of the cornea. This outer flap is folded back and the exposed inner tissue of the cornea is then reshaped with the laser. Afterward, the flap is folded back into place. This preserves the outer layers of the cornea and helps to speed healing.
