Cornea transplant or corneal transplantation, also called keratoplasty, is a procedure to replace the damaged or diseased cornea with a healthy, donated human cornea or an artificial cornea. If an artificial or prosthetic cornea is used the procedure is known as a keratoprosthesis or artificial cornea transplant. The procedure restores vision, reduces eye pain, and improves the appearance of the cornea if it is white and scarred due to damage.
There are two types of corneal transplant surgery, one is replacing the entire cornea with the healthy donor cornea also called full corneal transplant or penetrating keratoplasty. Second is a partial corneal transplant also called Lamellar keratoplasty where only part of cornea is replaced.
Please note that corneal transplant is only performed when other types of treatments are not effective. The doctor will let you know if the procedure is the only option you have to treat this problem.
