Transport and Preservation Comparison of Preloaded and Prestripped-Only DMEK Grafts.

Purpose: This study compares the effect of the transport of conventionally prestripped Descemet membrane endothelial keratoplasty (DMEK) tissue with the DMEK revolutionary advanced Preloadable Injection Device (RAPID) preloaded transport system from Geuder AG (Heidelberg, Germany). Endothelial cell loss, tissue integrity, endothelial cell phenotype, and viability were assessed and compared.

Methods: Twelve DMEK grafts were prestripped by the cornea bank and transported using the following 2 conditions: conventional flask (n = 6) or a preloaded transport cartridge (DMEK RAPID, n = 6).
