多焦点人工晶状体ACRYSOF ReSTOR的临床应用

Clinical Application of ACRYSOF ReSTOR Multifocal lntraocular Lens

目的探讨多焦点人工晶状体ACRYSOF ReSTOR的临床应用价值。方法对28例(30眼)白内障患者实施超声乳化并植入ACRYSOF ReSTOR人工晶状体(MIOL),对照组26例(30眼)植入ACRYSOF Nat-ural单焦点人工晶状体(SIOL)。术后3个月检查患者的裸眼远、近视力、矫正远、近视力及最佳远视矫正状态下的近视力,对比敏感度,并发症,并调查两组患者不同距离下的视物舒适与否、是否存在眩光等视觉症状及是否需要依赖眼镜。结果两组患者裸眼远视力、最佳矫正远视力、最佳矫正近视力无明显差异(P>0.05);裸眼近视力及最佳矫正视远度数的近视力,MIOL组明显优于SIOL组(P<0.05);两组患者的对比敏感度在各空间频率段差异均无显著性(P>0.05)。仅1例(3.33%)单眼植入MIOL患者诉头晕、眩光等症状,其他患者均无明显不适,满意程度较高。 MIOL组术后脱镜率为86.67%,SIOL组所有患者需配戴眼镜,两组有显著差异(P<0.05)。MIOL组2例(6.67%)、SIOL组3例(10%)发生后发性白内障,两组比较差异无显著性(P>0.05) 结论ACRYSOF ReSTOR多焦点人工晶状体能同时提供良好的远、中、近视力,提高白内障患者术后的生活质量。

Objective To evaluate the clinical effect of ACRYSOF ReSTOR muhifocal intraocular lens. Methods Fifty four patients （ 60 eyes ） with cataract were randomly divided into two groups. One group including 28 patients （ 30 eyes ） received ReSTOR multifocal intraocular lens implantation（ MIOL group） and the other group including 26 patients（30 eyes） received ReSTOR natural monofocal intraocular lens implantation （SIOL group）. Measurements were taken at 3 months after operation, including uncorrected distance naked acuity, best corrected distance visual acuity, near naked acuity, best corrected near visual acuity and distance corrected near visual acuity. The contrast sensitivity and complication were also evaluated. A questionnaire was adopted to evaluate visual function related quality of life, satisfaction and glasswearing conditions. Results The difference of distance naked acuity,best corrected distance visual acuity and best corrected near visual acuity between the two groups was not significant （ P 〉 0.05）. Near naked acuity and distance corrected near visual acuity were better in the muhifocal group than in the monofocal group（P 〈 0.05）. There were no significant differences between the MIOL and SIOL group in contrast sensitivity for all spatial frequencies（ P 〉 0.05 ）. Two patients（3.33 % ） with unilateral MIOL complained glare. 86.67% patients had no longer to wear glasses in the MIOL group,but almost all patients in the SIOL group had to wear glasses. The difference was significant （ P 〈 0. 05 ）. Two patients with after-cataract were found in the MIOL group and three in the SIOL group. The difference was not significant （ P 〉 0. 05 ）. Conclusion In addition to providing the distance acuity,the ReSTOR multifocal IOL helps to enhance the middle and near vision, so as to improve the patients＇ quality of life after operation.
