Corneal transplantation involves replacing a scarred or diseased cornea with a donor cornea. This procedure, also called keratoplasty, aims to restore corneal clarity and improve vision by using healthy donor tissue. The graft can be full-thickness (penetrating keratoplasty) or partial-thickness (lamellar keratoplasty), and the donor tissue is sutured into place with careful post-operative care to minimize rejection and astigmatism.

Enucleation means removing the entire eyeball, which is not a tissue replacement. An ocular prosthesis is a cosmetic device worn after eye removal. Radial keratotomy reshapes the cornea with incisions to change refractive power, not replace the corneal tissue.
