Explanation:
Astigmatism is a common vision problem caused by an error in the shape of the cornea. With astigmatism, the lens of the eye or the cornea, which is the front surface of the eye, has an irregular curve. This can change the way light passes, or refracts, to your retina. This causes blurry, fuzzy, or distorted vision.
Some people with astigmatism can be treated with laser eye surgery, the most common of which is laser in situ keratomileusis (LASIK). ... An excimer laser changes the shape of the cornea by removing tissue. When the cornea heals, it usually has a more even and spherical curve.
