Setting: Taipei Municipal Yang-Ming Hospital, Taipei, Taiwan. Methods: A prospective study of 70 cataractous eyes treated by phacoemulsification with IOL implantation was carried out. The eyes were randomized into 2 groups based on IOL type: 1-piece PMMA IOL; 3-piece silicone IOL. The amount of IOL tilt and decentration was measured and anterior chamber depth (ACD) determined by Scheimpflug photography using an anterior eye segment analysis system (EAS-1000, Nidek). All eyes were examined 1 week and 1 to 6 months after surgery. Results: No statistically significant differences were found in the amount of tilt and decentration between 2 IOL types throughout the study. The ACDs were relatively constant in both groups through the early postoperative periods. Conclusion: The stability of PMMA and silicone IOLS were the same after phacoemulsification.journal article10.1016/S0886-3350(98)80359-398509072-s2.0-0031760983https://api.elsevier.com/content/abstract/scopus_id/0031760983
