摘要 目的 比较在白内障合并青光眼病例中植入A cryso f R eSTOR (衍射型多焦点人工晶状体)及

A cry sof N atural (单焦点人工晶状体)后人工晶状体眼的视功能状态,评价多焦点人工晶状体在白内障合并青光眼病例中应用的临床效果及安全性。方法 将24例青光眼合并白内障患者(已行滤过性手术或虹膜根切术)在随机化基础上按自愿选择的原则分为两组,多焦点人工晶状体组11例(11眼),单焦点人工晶状体组13例(13眼),行白内障超声乳化吸除术,按分组植入不同类型的人工晶状体。术后1周、1个月、3个月观察术眼非矫正远、近视力,最佳矫正远、近视力,矫正远视力下近视力。结果 多焦点人工晶体组患者术后3个月平均裸眼远视力(0 78 0 11),平均裸眼近视力(0 63 0 09),矫正远视力下近视力(0 67 0 17)。术后裸眼远近视力较术前有显著提高。单焦点人工晶体组患者术后3个月平均裸眼远视力(0 77 0 11),平均裸眼近视力(0 36 0 17),矫正远视力下近视力(0 13 0 09)。结论 通过适当的选择患者,衍射型多焦点人工晶状体可为青光眼合并白内障患者提供良好的远、近视力,降低患者术后对眼镜的依赖。
