PURPOSE: The aim was to evaluate the results of three different secondary intraocular lens implantation (IOL) procedures in aphakic eyes without capsular support
METHODS: In this retrospective comparative case series, 90 eyes of 90 patients who underwent secondary IOL implantation for correction of aphakia were enrolled. Patients were divided into three groups based on the secondary IOL implantation procedure: anterior chamber iris-fixated IOL (AC-IFIOL), retropupillary iris-fixated IOL (RP-IFIOL), and scleral-fixated posterior chamber IOL (SF-PCIOL). The efficacy and safety of each procedure were assessed at follow-up.
RESULTS: All eyes had aphakia caused by a previous cataract surgery. A final corrected distance visual acuity of 20/40 or better was achieved in 22 eyes (62.9%) implanted with an AC-IFIOL, in 12 eyes (50%) with an RP-IFIOL, and 18 eyes (58.1%) with an SF-PCIOL. At final visit, mean postoperative endothelial cell loss was 175 cells/mm(2) (7.2%) in the AC-IFIOL group, 255 cells/mm(2) (11.4%) in the RP-IFIOL group, and 135 cells/mm(2) (5.9%) in the AC-IFIOL group (P > 0.05).
CONCLUSIONS: The study showed that AC-IFIOL, RP-IFIOL, and SF-PCIOL implantation had similar visual outcomes and mean corneal endothelial cell loss.
