• 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.
Why is Lasik Done?
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:
-
Nearsightedness (myopia). You see things clearly when they’re close to you, but things farther away are blurry.
-
Farsightedness (hyperopia). You see faraway things more clearly, but closer things are blurry.
-
Astigmatism. This can make everything blurry because of how your eye is shaped.
.
What are the Advantages of Lasik Surgery?
-
There’s very little if any pain involved.
-
There aren’t any bandages or stitches.
-
If your vision changes as you age, your doctor can adjust it.
-
You probably won’t need to use glasses or contacts as much, or at all, after Lasik.
