Corrective Eye Surgery
Corrective eye surgery, also known as laser eye surgery or refractive surgery, is a surgical procedure that corrects vision problems. There are different types of correction eye surgeries available to today’s patient. Two popular procedures are:
LASIK: LASIK stands for laser in-situ keratomileusis. LASIK eye surgery is used to correct vision in people who are nearsighted, farsighted, and for some types of astigmatism. It cannot correct all vision problems. LASIK works by reshaping the cornea by making a flap in the outer layer of the cornea so that the underlying tissue can be accessed. Numbing drops are used to eliminate pain. Most patients report a dramatic improvement in vision after undergoing LASIK surgery.
PRK: With PRK, the cornea is reshaped by removing a microscopic amount of tissue from the corneal stroma using a beam of light (laser). No flap is created. Recovery time is generally longer with PRK than with LASIK. However, since there is no flap, there are some benefits to PRK.
