Endothelial Cell Viability of Nonscrolled “Endo-Out” Preloaded Descemet Membrane Endothelial Keratoplasty Graft

We herein demonstrate that despite the DMEK graft being in a fully opened, nonscrolled configuration in the preloaded glass cannula, with the endothelial side facing outward, the endothelial cells were found to be viable. The evaluation and assessment of the DMEK graft were determined to be suitable for transplantation. We demonstrate that surgeons may likely accept such grafts with confidence.
