Although it may be desirable for vitrectomized cases with aniridia and aphakic bullous keratopathy without capsule support to undergo DSAEK, one of the major problems is lenticule detachment during surgery or in the postoperative period. To perform DSAEK in such cases, special surgical techniques are needed in order to facilitate adhesion of the lenticule. Herein, we describe a suture technique for attaching the endothelial lenticule in DSAEK for aniridic and aphakic cases that have undergone vitrectomy for traumatic vitreoretinal disease.Keywords: traumatic aniridia, aphakic bullous keratopathy, Descemet-stripping automated endothelial keratoplasty, vitrectomy
