AbstractAim: Aphakia with insufficient capsular support is a challenging situation that can be managed by multipleoptions. The purpose of this study is to evaluate iris claw IOL implantation as one available option as regards visualoutcome and complications.Methods: This was a prospective interventional study that included 26 eyes of aphakic patients with insufficientcapsular support diagnosed preoperatively or acquired intraoperatively. Data analyzed included best corrected visualacuity (BCVA), intraocular pressure (IOP), central endothelial cell density (CECD) and anterior chamber angle depthby optical coherence tomography preoperatively and postoperatively for 24 months.Results: 26 eyes of 17 patients received iris claw IOL implantation for correction of aphakia with insufficientcapsular support. Mean age of the patients was 32.8 ± 20.9, 13 patients (50%) underwent secondary implantationand the other 13 (50%) underwent primary implantation of iris claw IOL. The mean preoperative LogMAR BCVA was1.11 ± 0.28 improved to 0.63 ± 0.18 at 9 months postoperatively p-value (<0.001). Preoperative IOP was 18.7 ± 4.9mmHg, postoperative was 15.9 ± 3.5 mmHg. Preoperative CECD was 3337.6 ± 801.9 cell/mm2 changed to 2837.4 ±640.9 cell/mm2 at 3 months then to 2676.1 ± 664.4 cell/mm2 at 9 months postoperatively p-value (0.03) and then to2636.6 ± 652.6 cell/mm2 at 24 months postoperatively. Preoperative anterior chamber angle depth was 41.1 ± 4.4and postoperative was 42.8 ± 2.9.Conclusion: Iris claw IOL implantation is a safe option in cases of aphakia with insufficient capsular support withsignificant improvement in final visual acuity and early loss of endothelial cell density.
