A corneal transplant is a surgical procedure that replaces a disc-shaped segment of an unhealthy cornea with a similarly shaped piece of healthy donor cornea. Only human donor tissue can be used in corneal transplantation surgery. This operation is also called a corneal graft or keratoplasty.
If a donor cornea is unsuitable for transplant, eyes may be used for research and training, when consent is given for that purpose.

Conditions that require a corneal transplant
The two most common reasons for requiring a transplant are: bullous keratopathy – a condition in which the cornea becomes permanently swollen keratoconus – a corneal dystrophy in which the central zone of the cornea thins and becomes irregularly curved. Other reasons are: lattice, granular, macular and Fuch's dystrophy herpes virus infection of the eye corneal scarring due to hereditary or congenital corneal clouding severe bacterial infection.Corneal transplantation procedure
Corneal transplant is the oldest and most common form of human (other than ). In Australia, approximately 2,000 corneal transplants are performed each year.Corneal transplantation success rates
Cornea transplant operations are very successful. According to the Australian Corneal Graft Registry, the average one-year transplant survival rate is approximately 90 per cent, decreasing to 75 per cent at five years.Cornea donation
Almost anyone can donate their corneas (or other parts of their eyes). Unlike in organ donation, age and blood type are unimportant in determining cornea donor suitability. Similarly, donor eye colour and eyesight quality are not barriers to donation.Register as a donor
Telling your next of kin about your wishes is crucial for you to become a cornea donor at the time of your death. Individuals can also register with the .Using donated corneas
An eye bank is notified on the death of a potential donor who meets preliminary donation criteria. Retrieval of the cornea typically occurs within hours of death.If a donor cornea is unsuitable for transplant, eyes may be used for research and training, when consent is given for that purpose.
