To demonstrate a simulation model for donor preparation in Descemet membrane endothelial keratoplasty (DMEK).


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, demonstrating all the steps was recorded.


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.


The described simulation model can assist surgeons and eye bank technicians to learn steps in donor preparation in DMEK.
