Corneal transplants are taken from a donor and given to a recipient. The damaged cornea is removed and replaced with a donor cornea. There are some risks with this type of procedure, including hemorrhage or infection of the transplant area. Some other complications can include development of cataracts or glaucoma, rejection of the transplant cornea by the body or an irregular astigmatism development.
