目的:通过比较蓝光滤过型多焦点人工晶状体ReSTOR与蓝光滤过型单焦点人工晶状体Natural植入术后早期全程视力及脱镜率,了解ReSTOR植入后的临床效果。方法:收集在我院行超声乳化白内障摘出联合人工晶状体植入术的患者27例33眼,按植入人工晶状体种类的不同分为ReSTOR组(12例15眼)和Natural组(15例18眼),术后3mo测量患者最佳矫正远视力、最佳矫正远视力下的近视力,最佳矫正远视力下的中程视力(40,63,100cm),问卷调查两组患者的脱镜率及视物不良现象。结果:两组患者术后最佳矫正远视力无明显差异,ReSTOR组患者的最佳矫正远视力下的近视力和40cm,63cm,100cm下的中程视力及脱镜率较Natural组患者佳,差异有统计学意义(P<0.05)。结论:初步应用表明ReSTOR多焦点人工晶状体术后能获得较好的功能性视力。

·AIM:To compare overall visual acuity and the rate of spectacle independence after implantation of ReSTOR multifocal intraocular lens(IOL)and Natural single-focal IOL in patients with age-related cataract.METHODS:A total of 27 patients with age-related cataract were divided into two groups at random.One group of 12 patients(15 eyes)received ReSTOR multifocal IOL,another group of 15 patients(18 eyes)received Natural single-focal IOL.3 months after surgery,we observed patient’s best-corrected distance visual acuity(BCDVA),distance-corrected near visual acuity(DCNVA),independence on spectacles and the distance-corrected visual acuity in distance of 40cm,63cm and 100cm.RESULTS:BCDVA in the multifocal group were not statistically different from the single-focal group.DCNVA,independence on spectacles and the distance-corrected visual acuity in distance of 40cm,63cm and 100cm were statistically better in the multifocal group compared with the single-focal group(P<0.05).CONCLUSION:The ReSTOR multifocal IOL may obtain excellent overall visual acuity.
