LASIK/PRK
LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.
All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea.
Photorefractive Keratectomy Eye Surgery
Also known as PRK, this type of laser eye surgery can help if you are nearsighted, farsighted, or have astigmatism. It works best if your eye problem is mild or moderate.
All laser vision correction surgeries work by reshaping your cornea, the clear front part of your eye. Think of it like a windshield — light travels through it just and focuses on the retina in the back of your eye.
During PRK, an eye surgeon uses a cool pulsing beam of ultraviolet light on the surface of your cornea. LASIK, another type of laser surgery, works underneath your cornea.
