Replacement of damaged tissue on the eye’s clear surface, also is ref2242ed to as a corneal transplant, keratoplasty, penetrating keratoplasty or corneal graft.
Indications include: Scarring from eye herpes, fungal keratitis, keratoconus, hereditary factors, chemical burns, eye trauma, and failed corneal transplantation.
Replacement of the full thickness of the central part of the cornea with a donor cornea.
Replaces central corneal tissue with healthy corneal tissue.
An abnormal cornea affects vision by scattering or distorting light and causing glare and blurred vision.
Used to treat damaged cornea from chemical burns, trauma or keratoconus.
The grafted cornea is covered by corneal epithelium that migrates from the limbus.
42,000 cases a year.
Most common indication for cornea transplant is for Fuch’s corneal dystrophy.
Most successful of all transplants.
Graft survival at 8 months 93%.
Descemet’s Stripping Endothelial Keratoplasty (DSEK) uses only a very thin portion of the cornea for transplant, and may be superior to the more conventional full-thickness corneal transplant procedure for better vision outcomes and stability, as well as fewer risk factors.
Donor corneas are checked for clarity and are screened for presence of diseases such as hepatitis and AIDS.
A penetrating keratoplasty, involves the removal of the central portion of the diseased cornea and replacing it with a matched donor button of cornea.
