From eye donation, corneas can be transplanted.
Corneas are the clear dome-shaped part of an eye. They cover the colored iris and provide much of the eye's ability to focus and see clearly. Hereditary conditions, scarring after infection, irregular shaping and swelling can all cause the cornea to distort light, leading to a reduction in vision.
Most often performed on older people, cornea transplants can restore sight for people whose sight cannot be corrected by glasses or contacts alone.
As one of the most common and successful transplants performed in the United States, corneal transplants increase vision for about 40,000 people each year. Choosing to become an eye donor is the easiest way to give the gift of sight to someone who is otherwise left in the dark.
