Descemet Membrane Endothelial Keratoplasty Under Failed Penetrating Keratoplasty Without Host Descemetorhexis for the Management of Secondary Graft Failure

Abstract

DMEK under PK without host descemetorhexis is a feasible surgical alternative for the treatment of graft failure after PK. It is associated with equivalent levels of efficacy and safety compared with Descemet membrane stripping DMEK techniques but simplifies the surgical procedure and avoids potential intraoperative complications associated with Descemet stripping. Further studies with a larger sample and a longer follow-up are necessary to confirm our preliminary outcomes.
