Abstract

Purpose: To compare the results of foldable acrylic intraocular lens (IOL) implantation through a clear corneal incision with those of rigid IOL implantation in eyes having pars plana vitrectomy (PPV). Setting: Tertiary referral-based university institute. Methods: A consecutive retrospective comparative chart review was performed in all eyes that had PPV and foldable IOL implantation between May 15, 1999, and November 1, 2000 (n = 30), and all eyes that had PPV and rigid IOL implantation between April 1, 1996, and May 14, 1999 (n = 30). Preoperative baseline data and postoperative outcome data were recorded. Pars plana vitrectomy and associated vitreoretinal procedures were performed as indicated according to individual circumstances. A minimum of 1 week of follow-up information was available for all eyes. Results: Baseline characteristics in both groups of patients, including age, sex, eye involved, and phakic state, were similar. The preoperative visual acuities were also similar, ranging from 20/30 to hand motions; the mean visual acuity was 20/200. The IOL was implanted in all eyes uneventfully and did not restrict fundoscopy. The mean follow-up was significantly longer in the rigid IOL group (20 months) than in the foldable IOL group (7 months) (P<.001), probably because of the earlier case acquisition. The mean postoperative best corrected visual acuity was 20/200 in the foldable IOL group and 20/100 in the rigid IOL group. There was no difference between the 2 groups in the rate of postoperative retinal detachment, recurrent macular hole, or repeat PPV. Elevated intraocular pressure (IOP) on the first postoperative day was more common in the rigid IOL group than in the foldable IOL group (P = .078) because more patients in the rigid IOL group had surgery for diabetic ocular complications and these patients had a greater IOP rise. Conclusion: Acrylic IOLs can be safely implanted in conjunction with PPV in selected cases.
