A corneal transplant comprises the replacement of a diseased or scarred cornea with a new one. In corneal transplant surgery, the surgeon removes the central portion of the cloudy cornea and replaces it with a clear cornea, usually donated through an Eye Bank. After the surgery, eye drops, to aid the healing, would be needed for several months. The chances of success of this operation have risen dramatically because of technological advancement, such as less irritating sutures or threads, which are often finer than a human hair, and the surgical microscope. Corneal transplantation has restored sight to many, who, a generation ago, would have been blinded permanently by corneal injury, infection, or inherited corneal disease or degeneration.

What does the donor cornea come from?
The healthy donor cornea, used for transplantation, is supplied by an Eye Bank. Eye Banks collect, evaluate, store and distribute donated corneas. The corneas are collected from human donors within 6 hours of death. Stringent tests are performed to ensure the safety of the person receiving the cornea. The Eye Bank verifies the donor's medical history and cause of death and performs blood tests to ensure that the deceased person did not have contagious diseases like AIDS, hepatitis B or C, Rabies , Septicemia , Active leukemia etc. to ensure that the person in whose eye cornea is transplanted, is not caught by these dreaded diseases.
