Koenig Steven B. M.D.; Harris, Gerald J. M.D.Cornea: March 1991 Original Articles: PDF Only Buy Abstract Persistent donor corneal epithelial defects following penetrating keratoplasty may lead to graft failure.

This technique is simple and completely reversible, and it allows continued observation and instillation of topical medication during the postoperative period. © Lippincott-Raven Publishers.
