About The Study: This randomized clinical trial found that endothelial cell loss and morphometry 1 year after Descemet membrane endothelial keratoplasty (DMEK) were not affected by cornea donor diabetes status. With comparable 1-year graft success with tissue from donors with and without diabetes demonstrated in this trial, these findings support the use of corneas from donors with diabetes for endothelial keratoplasty procedures.
