摘　　要：目的:比较双眼植入多焦点人工晶状体(IOL)和单眼视设计两种方法对白内障术后视功能的影响。方法:选择2011-01/2012-01于本中心诊断为双眼白内障患者45例90眼,分为多焦点组23例和单眼视组22例,分别植入AcrySofReSTOR+3D多焦点IOL(SN6AD1,美国Alcon)和单焦点非球面AcrySofIQ(SN60WF)IOL。记录术后3mo时两组患者裸眼远、近、中距离视力,以及对比敏感度、立体视、视功能和生存质量调查问卷,评价患者主观的视觉功能和脱镜率。对计量资料中两组数据进行正态性检验分析,满足正态分布者行t检验,对计数资料行χ2检验。结果:术后两组双眼裸眼远视力(t=2.001,P=0.052)、中距离视力(t=1.304,P=0.199)、近视力(t=1.642,P=0.108),差异无统计学意义。各空间频率对比敏感度差异无统计学意义(P>0.05)。未矫正远距离立体视差异有统计学意义(P<0.05)。两组术后脱镜率均大于96%。主要视觉干扰中,复视、夜间视物困难和眩光多焦点组比例较高。结论:双眼植入多焦点IOL与单焦点IOL单眼视设计基本均能获得全程视力,术后脱镜率以及视功能无差异(P>0.05)。AIM： To compare visual function in patients with bilateral diffractive multifocal intraocular lenses （IOLs） and patients with monovision.METHODS：This study comprised consecutive bilateral cataract patients 45 cases （90 eyes） between March 2011 and January 2012. All cases were divided into two groups： multifocal IOL group （23 patients） with implantation of AcrySof ReSTOR ＋3D（SN6AD1） multifocal IOLs, monovision group （22 patients） with implantation of AcrySof IQ（SN60WF） IOLs. Parameters analyzed 3 months postoperatively included binocular uncorrected distance, intermediate, and near visual acuities, stereo vision, photopic, mesopic contrast sensitivity function without glare; spectacle independence and subjective visual symptoms. The independent-samples t test was used to compare the measured data which met normal distribution. The Chi-square test was applied to compare categorical variables. RESULTS： There were no significant differences between groups in bilateral uncorrected distance vision（t=2.001, P=0.052）, intermediate （t=1.304, P=0.199） and near vision（t=1.642, P=0.108）. Percentage of patients wearing spectacle for distance vision were less than 4% in all groups. On the questionnaire, patients in multifocal IOL group complained with double vision, trouble in night vision and halo.CONCLUSION： Pseudophakic monovision and multifocal IOL achieved distance vision, intermediate vision and near vision.
