Viability of preloaded Descemet membrane endothelial keratoplasty grafts with 96-hour shipment.

After 48 hours of shipping, tri-folded DMEK grafts demonstrated a comparable ECL to scrolled DMEK grafts, with a marginally significant trend demonstrating 4.3% less ECL in tri-folded as compared with scrolled grafts. 4 5 However, there has been limited investigation into the effect of extended shipping on DMEK grafts with a comparison between these two methods. 6 In 2019, over 28 000 corneas were exported internationally from the USA for keratoplasty. 7 The ease of said international transplants would be greatly improved if grafts could be preloaded and were to remain viable during prolonged shipping.
