Penetrating Keratoplasty - Cornea Research Foundation of.

Eye banks recover, prepare and deliver donated eyes for cornea transplants and research. The first successful cornea transplant was performed in 1905 and the first eye bank was founded in 1944. Currently, in the United States, eye banks provide tissue for over 80,000 cornea transplants each year to treat conditions such as keratoconus and corneal scarring.

Cornea is the transparent front surface of the eye. Normally, when looking straight on at the eye, you look right through the cornea and see the coloured iris and black pupil of the eye. Corneal transplantation or corneal grafting or keratoplasty involves removal of diseased or damaged cornea and its replacement by donated corneal tissue.

A cornea transplant replaces diseased or scarred corneal tissue with healthy tissue from an organ donor. There are two main types of cornea transplants: traditional, full thickness cornea transplant (also known as penetrating keratoplasty, or PK) and back layer cornea transplant (also known as endothelial keratoplasty, or EK).

Conductive keratoplasty, or CK, is an alternative to laser surgery for people who are over forty and have hyperopia, astigmatism, or presbyopia.Developed by Refractec, the process received FDA approval for reduction of hyperopia, and in March 2004 received the first FDA approval for vision technology to improve presbyopia.
