title: Long-term results of the foldable CeeOn Edge intraocular lens.
abstract: OBJECTIVE
  To determine the long-term efficacy and safety of the foldable silicone CeeOn Edge(R) model 911 intraocular lens (IOL).
  
  
  METHODS
  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.
