01: Background Patients with failed penetrating keratoplasties(PK) are sometimes offered repeat surgery with an artificial or donor cornea Both transplants involve removing the diseased recipient cornea, and replacing it with the donor or prosthetic cornea OBJECTIVE: To assess the effectiveness of artificial versus donor corneas in individuals who have had one or more failed donor corneal transplantations
02: Types of studies No randomized controlled trials or controlled clinical trials were identified.
05: Conclusions The optimal management for those individuals who have failed a conventional corneal transplantation is not known. To date, there have been no controlled trials comparing the visual outcomes and complications of artificial corneal devices.
