Donor tissue preparation for Descemet membrane endothelial keratoplasty

Abstract

Descemet grafts for transplantation in DMEK procedures can be surgically prepared from organ-cultured corneal rims and stored for an additional 3 weeks with acceptable endothelial cell loss. Because the donor tissue can be dissected directly from organ-cultured corneoscleral rims, donor preparation for DMEK can be readily accessible to most corneal surgeons.
