Purpose: To report one year clinical results of single piece acrylics soft intraocular lens (1P-IOL) (SA30AL, Alcon, USA) and compare them to three piece acrylic soft IOL (3P-IOL)(MA30BA, Alcon). Method: Fourteen patients with age related cataract were enrolled to the prospective study under the written informed consent and underwent phacoemulsification and aspiration, and insertion of 1P-IOL in one eye and 3P-IOL in the other. Nine cases were female, five were male, and averaged age was 71 (59-80). Operative interval was 2 days in 12 cases and 5 days in the other. All surgeries were performed by single surgeon (S. Y. ). Patients were examined at day 1,day 7, 1 m, 3 m, 6 m, and 12 months postop in a single blind manner. Results: Final BCVA was better than 20/20 in all eyes. Postoperative parameter including flare count (1P; 85 3P; 74 ), corneal endothelial cell loss(1P; 10.1%, 3P; 8.6%), IOL tilting, and IOL decentration revealed no significant difference at one year postop in both eyes. Light scattering evaluated with anterior segment image analysis system (EAS-1000, Nidek) showed no difference in anterior or posterior surface of optics at one year postop, however, it increased by time in all cases. No case had significant posterior capsule opacification or YAG laser capsulotomy during observation period. Conclusions: Single piece acrylicIOL may be equally advantageous to 3P-IOL, although long term prognosis should be determined.
