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. Copyright © 2018 Wolters Kluwer Health, Inc. All rights reserved.
