keratoplasty

Excision of corneal tissue and its replacement by a cornea from a human donor. This can be done either over the entire cornea (total keratoplasty) or over a portion of it (partial keratoplasty). Two main techniques are used: (1) the penetrating keratoplasty in which the entire thickness of the cornea is removed and replaced by transparent corneal tissue; (2) the lamellar keratoplasty in which a superficial layer is removed and replaced by healthy tissue. Common indications to perform keratoplasty are therapeutic (e.g. keratoconus, corneal ulcer) or cosmetic (e.g. removing an unsightly opacity). Syn. corneal transplant. See ciclosporin; granular dystrophy; eye bank; corneal graft; immunosuppressants.

Patient discussion about keratoplasty

Q. Has anyone had experience with a corneal transplant because of keratoconus?

A. my uncle had to do a transplant- it took 5 weeks until he could see anything , another year to get his vision straightened up. but now he is fine! i know that he looked for information in the "National Keratoconus Foundation". they were very helpful (and nice!), they have a website with information on all forms of treatment:
