PURPOSE: To determine the long-term efficacy and safety of the foldable silicone CeeOn Edge(R) model 911 intraocular lens (IOL). SETTING: Eye Clinic, Klinikum Minden, Germany. METHODS: A high-refractive-index silicone lens with a sharp edge was implanted after phacoemulsification in 42 eyes of 36 patients. Best corrected visual acuity (BCVA) and occurrence of complications were evaluated during a 3 year follow-up. RESULTS: No significant postoperative complications were seen. At 3 years, 26 eyes of 22 patients were available for examination. The BCVA was 0.5 (20/40) or better in 92% of eyes and 1.0 (20/20) or better in 39%. No posterior capsule opacification (PCO) was observed, and neodymium:YAG capsulotomy was not indicated in any patient. CONCLUSIONS: This pilot study indicates that the performance and safety of the foldable silicone CeeOn Edge lens are excellent. The results support the theory that a sharp edge on the IOL prevents the development of PCO.
