title: Effect of the Nd:YAG laser on polymethylmethacrylate, HEMA copolymer, and silicone intraocular materials.
abstract: Recent trends of cataract extraction feature both small surgical wounds and preservation of posterior capsules. The development of safe, reliable, and flexible implant materials that can withstand near impact with a Nd:YAG laser during secondary posterior capsule discissions are required. An in vitro experiment was performed to analyze the effects of Nd:YAG laser irradiation on polymethylmethacrylate (PMMA), hydroxyethylmethacrylate (HEMA), hydroxyethylhydroxymethylmethacrylate (HEMA-MEMA) copolymer combination, and a silicone compound. The HEMA and HEMA-MEMA compounds were the least susceptible to Nd:YAG laser damage in this laboratory setting.
