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 as those who have astigmatism.
LASIK works by reshaping the cornea with a cool 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.
LASIK is popular because it is a quick procedure with a high success rate. The surgery takes about 10 minutes and only requires local anesthesia in the form of eye drops. LASIK does not typically cause much discomfort. The results are often immediate and adjustments and sometimes be made in the future to correct vision if there are any changes.
