Reduction of Nd:YAG Capsulotomy Rates After Implantation of a Single-Piece Acrylic Hydrophilic Intraocular Lens with 360° Squared Optic Edge: 24-Month Results

BACKGROUND AND OBJECTIVE: Posterior capsule opacification remains a significant problem following cataract surgery. The aim of the study was to evaluate the incidence of symptomatic posterior capsule opacification requiring Nd:YAG capsulotomy in patients who underwent cataract extraction and implantation of the Rayner C-flex 570C intraocular lens (IOL) (Rayner Intraocular Lens, Ltd., Sussex, UK). PATIENTS AND METHODS: A retrospective study of 3,461 eyes that underwent cataract extraction and insertion of the Rayner C-flex IOL from January 2004 to December 2005. The cases that received Nd: YAG capsulotomies were evaluated. RESULTS: Over a 24-month period, 3,461 Rayner C-flex IOLs were implanted. Nd:YAG capsulotomy was performed in 58 of these cases. The rate of Nd:YAG capsulotomy was 0.6% at 12 months and 1.7% at 24 months. The mean time to Nd:YAG capsulotomy was 9.3 months (range: 1.3 to 22.7 months). The follow-up period was 5.3 to 29.0 months. CONCLUSION: The incidence of symptomatic posterior capsule opacification with the Rayner C-flex IOL is low.
