Retinal detachment surgery in eyes with iris-fixated phakic intraocular lenses: Short-term clinical results

Abstract

PURPOSE: To evaluate the safety of retinal detachment (RD) surgery in eyes with iris-fixated phakic intraocular lenses (pIOLs) and the efficacy of the pIOLs in correcting myopia after RD surgery. SETTING: Single university-based tertiary referral center. DESIGN: Retrospective case series. METHODS: Eyes that had RD surgery (RD group) and healthy fellow eyes (control group) of the same patients were evaluated over 1 year. Surgical success, corrected distance visual acuity (CDVA), anterior chamber depth (ACD), endothelial cell density (ECD), and intraocular pressure (IOP) were assessed preoperatively and postoperatively to evaluate the safety of the surgery. The uncorrected distance visual acuity (UDVA) and spherical equivalent were assessed to evaluate the efficacy of the pIOL after RD surgery. RESULTS: Twenty-two eyes of 11 patients were assessed. Reattachment was achieved in 10 eyes (90.9%) with the first intervention. After 1 year, the mean UDVA was 0.16 +/- 0.15 logMAR (SD) in the RD group and 0.09 +/- 0.12 logMAR in the control group (P=.332). The mean CDVA was 0.03 +/- 0.07 log MAR in the RD group. The differences in the mean postoperative ACD and ECD between the 2 groups were not significant (P=.088 and P=.270, respectively). The mean IOP in the RD group was significantly higher than in the control group up to 1 month postoperatively; thereafter, the difference was not significant. CONCLUSIONS: Preservation of a pIOL during RD surgery did not diminish the safety of the surgery. The efficacy of the pIOL in correcting myopia was not markedly compromised.
