Abstract

Silicone, as manufactured today, appears to be a biocompatible material. The safety and efficacy of silicone lenses are primarily related to the intraocular lens (IOL) design. We compared the edge finish of two three-piece polypropylene loop foldable silicone IOL designs (Allergan Medical Optics) and three one-piece designs (Staar Surgical Co., CooperVision-Cilco). Except for an early Staar one-piece design, all lenses including the more recent Staar lenses had acceptably smooth edges with minimal molding flash.

摘要

就目前生产的情况来看，硅酮似乎是一种生物相容性材料。硅酮晶状体的安全性和有效性主要与人工晶状体（IOL）的设计有关。我们比较了两种三件式聚丙烯袢可折叠硅酮人工晶状体设计（爱尔康医疗光学公司）和三种一体式设计（STAAR外科公司、库博光学-Cilco）的边缘光洁度。除了STAAR早期的一体式设计外，包括最新的STAAR晶状体在内的所有晶状体边缘都足够光滑，成型飞边极少。
