What is Successful management of a retained host Descemet's membrane after penetrating keratoplasty (PKP) — A case report about?

## Introduction and importance To report the 21st case showing the rare occurrence of retained Descemet's membrane (DM) following penetrating keratoplasty (PKP). We intend to investigate possible etiologies, expected sequelae, and outcome of neodymium-dpoed yttrium alumnium garnet (Nd: YAG) laser membranectomy. ## Case presentation Our case is a 74-year-old male who underwent PKP surgery in the right eye secondary to corneal decompensation following cataract surgery in addition to corneal thinning secondary to superficial keratectomy related to the pre-existing climatic droplet keratopathy (CDK). Postoperative assessment revealed a retro-corneal membrane within the anterior chamber, which was affecting his vision. ## Clinical discussion Based on the post-operative course and the decreased vision as an indication for intervention, it was decided to excise the retained DM. Membranectomy with Nd: YAG laser was performed, and the patient's visual acuity measurement improved from 20/400 to 20/25. However, the endothelial cell count decreased from 1479 to 520 cells/mm^2^ (35 % loss) at 15 months post YAG membranectomy with clear graft. Histopathological examination confirmed the clinical
