ReSTOR多焦点人工晶体的临床应用研究

目的探讨ReSTOR多焦点人工晶体的临床应用效果。方法选取30例（60眼）老年性白内障患者,按统一标准分为两组,其中双眼非同期植入ReSTOR多焦点人工晶体者15例设为MIOL组;双眼非同期植入单焦点人工晶体者15例设为SIOL组。均行角膜缘透明角膜切口,应用超声乳化术摘除白内障联合人工晶体植入。术后1?d观察术眼的屈光状态,裸眼远、近视力;术后1个月观察术眼的屈光状态,裸眼远、近视力,矫正远、近视力,最佳远矫下近视力,焦距深度,对比敏感度,远近立体视锐度,问卷调查视觉质量、各视觉功能区满意度及脱镜率。结果术中术后无严重并发症。两组患者术后均有良好的远视力;MIOL组患者同时获得良好的近、中程视力。术后对比敏感度MIOL组较SIOL组有所下降,但无功能性意义。MIOL组有80%（12例）的患者裸眼近立体视锐度≤60?s,SIOL组所有患者裸眼近立体视锐度≥400?s,差异有统计学意义（χ2=26.28,P＜0.05）;MIOL组有93.33%（14例）的患者矫正近视力下近立体视锐度≤60?s,SIOL组有33.33%（5例）患者矫正近视立下近立体视锐度≤60?s,差异有统计学意义（χ2=12.59,P＜0.05）。MIOL组视近脱镜率80%。结论ReSTOR多焦点人工晶体植入安全有效,可为患者提供良好的全程视力及双眼视觉,患者满意度较高。

ReSTOR multifocal intraocular lens

Objective To evaluate the clinical effect of the ReSTOR multifocal intraocular lens.Metheods 30 age-related cataract patients(sixty eyes) were divided into two groups with the same standard.All patients accepted phacoemulsification and IOL implantation.15 patients were bilaterally implanted with the Alcon ReSTOR step-progressive-diffraction foldable multifocal IOL(MIOL)and 15 with Alcon Nature blue-filter foldable monofocal IOL(SIOL).Distance visual acuity,near visual acuity and depth of focus were observed...
