keratoplasty
Pronunciation: ker-AT-oh-plas-tee
Corneal transplantation surgery involving replacement of diseased corneal tissue with healthy donor tissue.
Full Definition
Keratoplasty encompasses various surgical techniques for corneal transplantation, ranging from full-thickness penetrating keratoplasty to partial-thickness procedures like DSEK, DMEK, and DALK. The choice of technique depends on which corneal layers are affected by disease. Donor tissue is obtained from eye banks and must be carefully matched for size and quality. Post-operative management includes immunosuppressive medications to prevent graft rejection.
Usage
Usage note: Specify the type of keratoplasty (penetrating, lamellar, endothelial) for clarity in surgical documentation.
