Preoperative Evaluation in Descemet Membrane Endothelial Keratoplasty for Secondary Penetrating Keratoplasty Graft Failure

Over the past decade, Penetrating Keratoplasty (PKP) graft failure has been increasingly managed by Descemet Membrane Endothelial (DMEK). Moreover, Anterior Segment Optical Coherence Tomography (AS-OCT) is becoming as essential modality for perioperative evaluation. Our aim to share important surgical considerations and modifications based on preoperative evaluation using AS-OCT and, consequently, present our clinical outcomes of DMEK performed secondary PKP failure.
