摘　　要：目的:通过观察白内障超声乳化摘除联合ReSTOR衍射型多焦点人工晶状体植入术后患者的视力、受眩光、光晕干扰程度及老视镜脱镜率,评价衍射型多焦点人工晶状体眼的视觉质量。方法:将60例(68眼)年龄相关性白内障患者随机分为2组,分别行白内障超声乳化摘除并植入ReSTOR SA60D3衍射型多焦点人工晶状体(多焦组)和Natural SN60AT单焦点人工晶状体(单焦组),观察术后裸眼及最佳矫正远、近视力,受眩光、光晕干扰程度及阅读时戴镜情况。结果:两组患者术后裸眼远视力、最佳矫正远视力和最佳矫正近视力均无显著性差异(P>0.05)。多焦组术后裸眼近视力和最佳视远矫正时近视力明显优于单焦组(P<0.05),且近距离阅读时不需戴老视镜的患者多焦组22例(73.3%),而单焦组仅4例(13.3%),差异有统计学意义(P<0.05)。多焦组患者术后受眩光、光晕干扰较单焦组明显(P<0.05)。结论:ReSTOR衍射型多焦点人工晶状体能提供良好的远、近视力,有效降低患者对老视镜的依赖,提高了白内障患者术后的视觉质量。Objective ： To obverse visual acuity, visual symptom and the rate of spectacle independence after implantation of a multifocal intraocular lens （MIOL） in patients with agerelated cataract. Methods： Sixty patients （68 eyes） with age-related cataract were enrolled in two groups. ReSTOR SA60D3 MIOL and Natural SN60AT monofacal intraocular lens were specially implanted after phacoemulsification. Uncorrected distance visual acuity （UCDVA）, best-corrected distance visual acuity （BCDVA）, uncorrected near visual acuity （UCNVA）, best-corrected near visual acuity （BCNVA）, distance-corrected near vision acuity （DCNVA）, visual symptom and the rate of spectacle independence were observed. Results： UCDVA and BCDVA in multifocal group were not statistically different from those in monofocal group （P 〉 0.05）. UCNVA and DCNVA were statistically better in multifocal group than in monofocal group （P 〈 0.05）.The multifocal group hashigher rate of speetable independence than the monofoeal group （73.3% versus 13.3%） （P 〈 0.05 ） when reading.The visual symptom such as glare and halo were more serious in multifoeal group than in monofoeal group （P 〈 0.05 ）. Conclusions： Aerysof ReSTOR apodized diffractive multifoeal intraoeular lens may provide an excellent distance and near visual acuity, and decrease the dependence of spectacle.
