Abstract

Purpose:To demonstrate a simulation model for donor preparation in Descemet membrane endothelial keratoplasty (DMEK).Methods:The inner transparent membrane of the onion (Allium cepa) was used as a simulation model for human Descemet membrane (DM). Surgical video (see Video, Supplemental Digital Content 1, http://links.lww.com/ICO/A663) demonstrating all the steps was recorded.Results:This model closely simulates human DM and helps DMEK surgeons learn the nuances of DM donor preparation steps with ease. The technique is repeatable, and the model is cost-effective.Conclusions:The described simulation model can assist surgeons and eye bank technicians to learn steps in donor preparation in DMEK.
