Abstract
To evaluate the efficacy of combined procedure of Descemet’s membrane endothelial keratoplasty (DMEK) and posterior iris-claw-fixated intra ocular lens (IOL) implantation in the management of aphakic bullous keratopathy (ABK). Sankara eye centre, a tertiary eye care centre. A prospective case series analysis. A prospective study comprised ten eyes of ten patients who underwent DMEK and posterior iris-claw-fixated IOL. Mean follow-up period was 12–36 months. Pre-operative and post-operative best corrected visual acuity (BCVA), endothelial cell density (ECD) and complications were noted. A total ten eyes of ten patients underwent DMEK. Out of ten patients BCVA improved from 1.00 to 1.60 LogMAR with mean and SD of 1.40 ± 0.20 to +0.20–0.40 LogMAR with mean and SD of 0.30 ± 0.07, with a significant p value of <0.001, Mean ECD of the donor tissue pre-operatively was 2367 cells, whereas 24 months post-operatively it was reduced to 1798 cells. Mean reduction in ECD pre procedure and post procedure was 569 (24 %). Iris-fixated IOL appears to offer simplicity in implantation and may be combined with DMEK in ABK. This procedure provides a faster visual recovery than other endothelial keratoplasties with iris-fixated IOL.
