Abstract

Various complications following intraocular lens (IOL) surgery result in explantation of the lenses. Haptic fibrosis may necessitate cutting the IOL haptics prior to removal. In this study we used the neodymium: YAG (Nd:YAG) laser to cut polypropylene and poly(methyl methacrylate) (PMMA) haptics in vitro and in rabbit eyes. In vitro we were able to cut 100% of both haptic types successfully (28 PMMA and 30 polypropylene haptics). In rabbit eyes we were able to cut 50% of the PMMA haptics and 43% of the polypropylene haptics. Poly(methyl methacrylate) haptics were easier to cut in vitro and in vivo than polypropylene haptics, requiring fewer shots for transection. Complications of Nd:YAG laser use frequently interfered with haptic transections in rabbit eyes. Haptic transection may be more easily accomplished in human eyes.

摘要

人工晶状体（IOL）手术后的各种并发症会导致晶状体被摘除。襻纤维化可能需要在摘除前切断人工晶状体的襻。在本研究中，我们使用钕：钇铝石榴石（Nd：YAG）激光在体外和兔眼中切割聚丙烯和聚甲基丙烯酸甲酯（PMMA）襻。在体外，我们成功切割了100%的两种襻类型（28个PMMA襻和30个聚丙烯襻）。在兔眼中，我们能够切割50%的PMMA襻和43%的聚丙烯襻。聚甲基丙烯酸甲酯襻在体外和体内比聚丙烯襻更容易切割，切断所需的激光发射次数更少。Nd：YAG激光使用的并发症经常干扰兔眼中襻的切断。襻切断在人眼中可能更容易完成。
