NEW WINDOWS FOR SIGHT
Ophthalmologists perform over 40,000 corneal transplants each year in the United States. Of all transplant surgery done today -- including hearts, lungs and kidneys -- corneal transplants are by far the most common and successful.
WHAT IS THE CORNEA?
The cornea is the clear front of the eye that covers the colored iris and the round pupil. Light is focused while passing through the cornea so we can see. To stay clear, the cornea must be healthy.
If the cornea is damaged it may become swollen or scarred. In either case, its smoothness or clarity may be lost. The scars, swelling or an irregular shape cause the cornea to scatter or distort light, resulting in glare or blurred vision.
A corneal transplant is needed if vision cannot be corrected satisfactorily or painful swelling cannot be relieved by medications or special contact lenses.
