LASIK, which stands for laser in-situ keratomileusis, is a popular surgery that can correct vision in people who are nearsighted or farsighted, or who have astigmatism.
It’s one of many vision correction surgeries that work by reshaping your cornea, the clear front part of your eye, so that light focuses on the retina in the back of your eye.
When light doesn’t focus on your retina the way it should, your vision is blurry. Doctors call this a refractive error. The basic types include:
Are younger than 18, Take certain medications, Have a lot of recent changes to your vision prescription, Have thin or uneven corneas, Have eye conditions such as glaucoma or very dry eyes, Have other health issues such as diabetes,lupus,or rheumatoid arthritis.
