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.

摘要

白内障摘除术的近期趋势包括手术切口小和保留后囊。需要开发出安全、可靠且灵活的植入材料，使其在二次后囊切开术中能够承受钕：钇铝石榴石激光的近距离冲击。进行了一项体外实验，以分析钕：钇铝石榴石激光照射对聚甲基丙烯酸甲酯（PMMA）、甲基丙烯酸羟乙酯（HEMA）、甲基丙烯酸羟乙酯-甲基丙烯酸羟甲酯（HEMA-MEMA）共聚物组合和一种硅酮化合物的影响。在本实验室环境中，HEMA和HEMA-MEMA化合物对钕：钇铝石榴石激光损伤最不敏感。
