| Popis: | Introduction: Iris-claw Intraocular Lens (IOL) is one of the alternatives to correct aphakia without sufficient capsular support. This technique is preferred because it has a simple procedure. Iris-claw IOL was originally designed to be fixated on the anterior chamber. The use of retropupillary fixation is increasing because the location is more physiologic and it shows less risk to corneal endothelial damage. Purpose: To describe safety and efficacy of iris-claw Artisan IOL in correcting aphakia without sufficient capsular support. Methods: This is a descriptive retrospective study of patients with aphakic iris-claw Artisan IOL implantation in National Eye Center Cicendo Eye Hospital, Indonesia from July 2017-July 2019. Patients were divided into prepupillary and retropupillary group. The Uncorrected Visual Acuity (UCVA), Best-Corrected Visual Acuity (BCVA), Safety Index (SI), Efficacy Index (EI), and complications were recorded. The procedure is safe if SI value ≥ 1.0 and effective if EI value ≥ 1.0. Results: There were 54 eyes in the retropupilary group and 17 eyes in the prepupillary group. In the prepupillary group, there were 94.11% eyes with SI ≥ 1.0, the mean SI was 1.79 ± 1.02, 50% of eyes with EI ≥ 1.0, and the mean EI was 0.77 ± 0.20. In the retropupillary group, there were 96.29% eyes with SI ≥ 1.0, the mean SI was 2.49 ± 2.23, 74.07% of eyes with EI ≥ 1.0, and the mean EI was 1.75 ± 1.64. Postoperative UCVA and BCVA were improved significantly compared to preoperative visual acuity in both groups (p < 0.05) Conclusion: Prepupillary and retropupillary iris-claw IOL implantation are safe. Retropupillary fixation technique is more effective in improving visual acuity. |
