Unfolding Techniques for the DMEK Graft
In Descemet membrane endothelial keratoplasty (DMEK), graft unfolding is often perceived as the most difficult step and the most challenging to learn [1–3]. Of course, the best way to learn anything is by practice, and for DMEK surgery, there exist both an animal eye model  and a method for simulating the operation using an artificial anterior chamber (which is how we teach graft unfolding at our wet-lab courses). Beginning surgeons may also be comforted to know that most clinical outcomes during the “learning curve” of the operation approximate those obtained by more experienced hands [5–7].
