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.
