PURPOSE: The purpose of this study was to evaluate the safety and efficacy of iris claw intraocular lens implantation for correction of aphakia in vitrectomized eyes without capsular support. METHODS: This was a prospective interventional case series. Twelve aphakic vitrectomized eyes without capsular support underwent iris claw intraocular lens implantation. The main outcome measures were changes in uncorrected visual acuity, best-corrected visual acuity, spheric equivalent, corneal endothelial cell density, corneal thickness, central macular thickness, and complications. RESULTS: Mean follow-up was 15.58 +/- 3.80 months with no intraoperative complications. Postoperatively, uncorrected visual acuity increased significantly at all follow-up visits (P < 0.05). Mean best-corrected visual acuity increased 10 letters/2 lines at the final follow-up visit (P = 0.023). Mean postoperative spheric equivalent at the last visit was -1.68 +/- 063 D, and the spheric equivalent was within +/-2.00 D of emmetropia in 9 (75%) eyes. Mean central macular thickness increased only at postoperative Month 3 (P = 0.043). Mean endothelial cell density loss was 23.87% at the last visit. Mean corneal thickness did not change during follow-up (P > 0.05). No corneal edema was observed. Complications were transient intraocular pressure increase (n = 1), cystoid macular edema (n = 1), and haptic dislocation replaced by surgery (n = 1). Retinas remained attached in all eyes. CONCLUSION: Secondary iris claw intraocular lens implantation is clinically safe and effective to correct aphakia in vitrectomized eyes without capsular support. Larger studies with longer follow-up are warranted.
