dc.description.abstractPurpose: To analyze and compare the outcomes and complication rates of secondary implantation of flexible, open-loop, anterior chamber intraocular lenses (AC IOLs) and single-piece, scleral-fixated, posterior chamber IOLs (PC IOLs). Setting. Departments of Ophthalmology, Gaziantep University Medical Faculty, Research Hospital, Gaziantep, and Inonu University Medical Faculty, Research Hospital, Malatya, Turkey. Methods: This study comprised 124 eyes of 113 aphakic patients (61 men, 52 women) with insufficient capsule support who had secondary IOL implantation from January 1997 to June 2001. In Group 1 (n = 73 eyes), a flexible, open-loop AC IOL was implanted and in Group 2 (n = 51 eyes), a single-piece, scleral-fixated PC IOL. The mean follow-up was 34 months (range 6 to 53 months) and took place at several different clinical settings. The mean interval between the initial cataract operation and secondary IOL implantation was 63 months (range 6 months to 12 years). The postoperative outcomes, safety, efficacy, and complication rates were analyzed, and the preoperative and postoperative best spectacle-corrected visual acuities (BSCVAs) were compared. Results. The postoperative mean BSCVA was 20/34.8 +/- 45.2 (SD) in Group 1 and 20/32.1 +/- 33.7 in Group 2; the difference was not significant (P =.718). A BSCVA of 20/40 or better was achieved in 62 eyes (84.9%) in Group 1 and 45 eyes (88.2%) in Group 2. A BSCVA of 20/25 or better was achieved in 40 eyes (54.8%) and 33 eyes (64.7%), respectively. The difference between the 2 groups was not significant (P =.472). Complications occurred in 25 eyes (34.2%) in Group 1 and 13 eyes (25.5%) in Group 2 (P >.05). The most frequent complications in Group 1 were early transient corneal edema, intraocular pressure elevation, cystoid macular edema, hyphema, secondary glaucoma, and iris capture or pupil decentration and in Group 2, suture erosion, a tilted or decentered IOL, fibrin reaction, and vitreous prolapse into the anterior chamber. Conclusions: The AC IOLs and PC IOLs were safe and effective for secondary implantation to correct aphakia. Secondary implantation of the scleral-fixated PC IOL seemed to provide a more favorable outcome and a lower complication rate than the open-loop AC IOL in complicated cataract cases with inadequate capsule and zonular support. As scleral-fixated PC IOL implantation is technically more difficult than AC IOL implantation, the decisive factor in choosing a secondary IOL is surgical experience. Long-term comparison of both techniques is required.en_US
