corneal surgery |
|
- The clear covering of the eyeball is called the cornea. Surgery is performed on the cornea for two main reasons. One is to remove scarring and clouding that interferes with vision. The other purpose of surgery is to change the curve of the cornea to correct vision problems such as nearsightedness or farsightedness. Operations on the cornea can performed either with traditional surgical tools or as laser surgery. |
