Corneal transplantation, also called corneal grafting, replaces a damaged or diseased cornea, the transparent front portion of the eye covering the iris, pupil and anterior chamber, with donated tissue. It takes two main forms, penetrating keratoplasty, in which the entire cornea is replaced, and lamellar keratoplasty, in which only part of it is replaced, and it is typically performed by an ophthalmologist on an outpatient basis, with donors of any age, including children, able to contribute tissue. The procedure is recommended for corneal blindness when medicine, conservative surgery for keratoconus or corneal cross-linking can no longer restore the cornea, and as of 2021 success rates reached roughly 41 percent or higher.

FAQs
Can a corneal transplant be rejected?
Yes. It can happen at any time and is usually treatable with steroids if found quickly.
Yes. Transplant rejection, where the immune system attacks the new cornea, is one of the recognized complications of a cornea transplant. The NHS notes that it can happen at any time after the transplant and can usually be treated with steroids if it is found quickly. Other possible problems include the new piece of cornea becoming cloudy or getting dislodged, which may mean more surgery.
