Cornea Surgery
The cornea is the structure you touch if you accidentally poke yourself in the eye. It is obviously very sensitive and is actually completely colorless and transparent, like a curved window that allows light to pass freely into the eye. Most corneas are round (like the surface of a basketball.) When the cornea is shaped like a football, this causes a condition caused astigmatism.
Astigmatism produces blurred vision that can be made clearer by wearing glasses. Diseased corneas can be surgically replaced via a corneal transplant. This is sometimes necessary when the normal cornea becomes cloudy due to age or injury. Cornea surgery is most often performed to correct vision, whether you’re nearsighted, farsighted, or have an astigmatism. There are two ways to do this: laser and implants.
Laser Vision Correction (LVC) Surgery
If you are nearsighted, it is because your cornea is either too steeply curved or your eye is too long. In these cases, LVC surgery is performed to flatten the cornea. On the other hand, if you are farsighted, LVC is used to increase the curvature and thereby steepen the cornea. In the case of an astigmatism, certain parts of the cornea are too steep while other parts are too flat. Again, LVC is used to reshape the cornea and eliminate astigmatism. Types of LVC cornea surgery include PRK, LASIK, and LASEK.
