Purpose: To evaluate the outcomes of secondary Descemet membrane endothelial keratoplasty (DMEK) after failed primary DMEK. Design: Retrospective, interventional case series. Participants: Fifty-five DMEK recipients 42 to 89 years of age. Methods: An initial consecutive series of 1655 DMEK surgeries was reviewed to identify cases of secondary DMEK after failed primary DMEK (n 1⁄4 55). A paired ...

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, consequent...

PURPOSE To compare the morphology of clear corneal incisions (CCIs) created with a femtosecond laser (Catalys) or a keratome (2.65 mm steel) during phacoemulsification using anterior segment optical coherence tomography (AS-OCT) and analyze the intended versus the achieved morphologic characteristics of femtosecond laser-generated CCIs. SETTING Northwestern University Feinberg School of Medic...

To relate a case not described previously in the national multilateral ophthalmological literature of Descemet’s membrane. A 59-year-old pseudophakic woman diagnosed with bullous keratopathy underwent penetrating keratoplasty an unusual finding multiple layers membrane, which were variable shape and thickness. In addition, ovoid bodies negative Gocott-Gomori (GMS) color present. Discussion Conc...
