It is a pain-free procedure and the surgery only takes 15 minutes. In this article, we will explain why LASIK surgery is done, what are its risk factors and how is the procedure carried out.

Why LASIK surgery is performed

LASIK eye surgery is performed when you have the following vision problems:

Myopia - When your eyeball is a little longer than its normal size, myopia occurs It is a common vision condition in which you can see near objects, but the far-away objects are blurry.

Hyperopia - It is another vision problem that occurs when you have a shorter eyeball that is too flat. This makes near vision blurry.

Astigmatism - It occurs when the shape of the cornea is irregular, and causes blurry vision. This surgery isn't for people who have very large pupils, severe myopia, and age-related eye diseases and who participate in contact sports.
