摘　　要：目的:测定衍射折射型多焦点人工晶状体眼术后远期的视觉质量。方法:采取随机对照临床试验研究方法,将67例白内障患者分两组,其中30例33眼植入多焦点人工晶状体,37例37眼植入单焦点人工晶状体。术后3mo和1a进行裸眼远视力、中间视力、近视力、矫正远、中、近视力和对比敏感度检查。视功能和生存质量调查问卷评价患者主观的视觉功能。结果:(1)术后多焦点组裸眼近视力优于单焦点组(P<0·05),中间距离视力亦优于单焦点组(P<0.05),两组裸眼和矫正远视力、近视力及最佳矫正远视力下近视力差异无显著性。术后1a和3mo相比,差异无显著性意义。(2)术后两组对比敏感度均低于正常范围,空间分布差异无统计学意义。(3)两组术后多焦点组脱镜率达83%,而单焦点组脱镜率为32%,两组比较差异有显著性(P<0·05)。多焦点组4例有眩光。多焦点组患者对全程视力的满意度高于单焦组患者。结论:多焦点人工晶状体能提供良好的全程视力,但近视力更好,视觉症状轻,脱镜率更高,有效地提高白内障患者术后的视觉质量。AIM：To evaluate visual quality and the quality of life in patients after the implantation of the apodized diffractive Acrysof ReSTOR multifocal intraocular lens（IOL）.METHODS：Sixty-seven patients （70 eyes） with age-related cataract were divided into two groups.Thirty cases （33 eyes） were performed with phacoemulsification and implanted with the apodized diffractive Acrysof ReSTOR multifocal intraocular lens （MIOL）, and the other 37 cases （37 eyes）were implanted with AcrySof Natrural monofocal intraocular lens （SIOL）.The uncorrected distance and near visual acuity, best distance and near visual acuity and intermediate uncorrected visual acuity were examined after surgery in all patients. Contrast sensitivity function was tested. The quality of life was observed by questionnaire at 3 months and 1 year. RESULTS：There was no significant difference between the two groups about the uncorrected,the corrected distance and near visions（P〉0.05）,while the postoperative near visual visions without corrected in the multifocal group was significantly better than that in the monofocal group （P〈0.05）.There was no significant difference in the multifocal group at 1 year and 3 months. Contrast sensitivity of eyes with MIOL was lower than that with SIOL. The spectacle independence in MIOL and SIOL groups were 83% and 32%. Intermediate uncorrected visual acuity in MIOL group was better than that in SIOL group. There were four patients complained with halo. Patients in MIOL group were satisfied with the better near visual acuity. CONCLUSION： The apodized diffractive Acrysof ReSTOR multifocal IOL may provide excellent full range of vision and higher percentage of spectacle independence, then improved quality of life for patients after phacoemulsification
