PURPOSE: To compare the incidence of retinal detachment within 6 months of cataract surgery complicated by vitreous loss in eyes with a posterior chamber intraocular lens (PC IOL) or an anterior chamber IOL (AC IOL).
SETTING: Department of Ophthalmology, Kaplan Medical Center, Rehovot, Israel.
METHODS: In this retrospective consecutive nonrandomized comparative case series, all cases of cataract surgery complicated by vitreous loss between January 1991 and March 1998 were reviewed. Included were patients who had thorough anterior vitrectomy and primary IOL implantation and at least 6 months follow-up. Exclusion criteria were congenital and traumatic cataract, previous intraocular surgery, and previous retinal detachment. Patients receiving an unsutured single-piece poly(methyl methacrylate) (PMMA) PC IOL formed the PC group, while those receiving flexible open-loop single-piece PMMA AC IOLs formed the AC group. The incidence of postoperative retinal detachment in the 2 groups was compared.
RESULTS: Of the 151 eyes of 149 patients, 66 received a PC IOL and 85 received an AC IOL. Two eyes (3.0%) in the PC group and 2 (2.4%) in the AC group developed retinal detachment; the difference between groups was not statistically significant (P = 1.00, Fisher exact test).
CONCLUSIONS: In eyes that have vitreous loss and thorough anterior vitrectomy, AC IOL implantation did not appear to increase the incidence of retinal detachment.
