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. |

corneal transplant |
|
- The cornea is the clear covering of the eyeball. With corneal transplantation, a part of a person's cornea is removed. It is then replaced with a portion of a cornea from a donor eye. In some cases, only the surface portion of the cornea needs to be removed. This is referred to as lamellar keratoplasty. In the majority of cases, however, the entire thickness of the cornea must be replaced. This is called penetrating keratoplasty. |
