蓝光滤过型折叠人工晶体在白内障超声乳化手术中的应用

目的探讨蓝光滤过型折叠人工晶体在白内障超声乳化手术中的临床应用。方法对90例93眼白内障患者在行超声乳化白内障吸除后植入蓝光滤过型人工晶体,其中有80例83眼植入Acrysof Natural型折叠人工晶体,10例10眼植入Acrysof IQ型非球面人工晶体。结果 90例93眼患者术后均无自述视物时亮度、颜色异常等,术后第一天视力≥1.0者38眼,≥0.5者62眼,≥0.1者85眼,0.1以下者8眼;术后第一周视力≥1.0者48眼,≥0.5者78眼,≥0.1者93眼;术后一个月进行屈光检查仅有4眼出现+0.50D散光;术后有36眼有不同程度的角膜水肿及后弹力层皱折,大部分均于术后3天内完全消失,少部分于术后7天消失。术后有1眼人工晶体后襻脱入前房。结论在白内障超声乳化手术中植入蓝光滤过型折叠人工晶体,具有切口小、术后散光小、无术后蓝视症,除了吸收紫外线外还吸收部分蓝光,其吸收光谱非常接近于自然状态,它最大可能地保留了人眼对光线的滤过、吸收和通过的特性,临床观察效果满意。

Objective To report the clinical application of Blu-ray filtering inlraocular lens folding in Phacoemulsification cataract surgery. Methods Implanting Blue-ray filtering intraocular lens folding to 93 eyes of 90 Cataract patients after phaco.Among these,83 eyes of 80 patients have been implanted Acrysof Natural Folding intraocular lens,10 eyes of 10 patients have been implanted Acrysof IQ Aspheric intraocular lens. Results All procedures were performed on 93 eyes of these patients without blue-sight disease.At the postoperative 1 day of follow-up,the visual acuity of 40.9% of the surgical eyes was above 1.0, 66.7% was above 0.5, 91.4% was above 0.1.eight eyes were below 0.1. At the postoperative 1 week of follow-up, the visual acuity of 51.6% of the surgical eyes was above 1.0, 83.9% was above 0.5, 100% was above 0.1.Carried out Optometry after 1 month,4 eyes showed ＋0.50D Astigmatism.After the operation ,36 eyes showed different degrees of corneal edema and Descemefs layer fold, with most of them disappeared at^er 3 days, and few of them disappeared alter 7 days. But there was 1 Inlraoeular lens was take into anterior chamber after the operation. Conclution Phacoemulsification cataract surgery in the implantation of foldable inwaocular filtering-ray crystal, with a small incision,small postoperative astigmatism, blue-sight disease .in addition to the absorption of ultraviolet absorption, but also some blue, very close to its absorption spectrum natural slate, it retains the greatest possible human eye to light of filtration, absorption and through the characterizes, clinical observations with satisfactory clinical result.
