Photorefractive Keratectomy (PRK) is where the surface of the lens is reshaped by a laser burning away part of the lens to correct vision. Laser-Assisted In Situ Keratomileusis (LASIK) is a procedure where the lens of the eye is mostly cut off, then flipped over and reshaping is done to the underside and then the "flap" is placed back in position. The advantage of LASIK is much quicker healing with very little or no scar tissue and far less discomfort. PRK required drops to be placed in the eyes for a week or two after the procedure to slow the healing process to prevent scar tissue.
