LASIK stands for laser in-situ keratomileusis and is a popular surgery to correct vision problems. LASIK can help people who are nearsighted or farsighted, as well those who have astigmatism.
LASIK works by reshaping the cornea with a laser, which allows light to be correctly focused onto the retina. A laser is used to create a small flap in the cornea, which is peeled back so another laser can reshape the cornea. The flap is then placed back and the surgery is complete.
