摘 要:目的观察衍射型非球面多焦点人工晶状体(IOL)植入术后的远期视觉质量。方法回顾性队列研究。收集2009年9月至2011年1月在郑州大学第一附属医院眼科行超声乳化白内障吸除联合IOL植入术的白内障患者130例(170只眼),其中男性67例,女性63例,年龄50.0-78.0岁,平均(66.5±10.1)岁。依据术中植入的IOL的不同类型分为3组:非球面多焦组42例(57只眼)、非球面组43例(57只眼)、球面组45例(56只眼)。分别于术后1年、3年、5年,观察裸眼及矫正远、中、近视力;昼夜有、无眩光的对比敏感度;以i-Traee视觉功能分析仪分析眼内像差、调制传递函数;远、近立体视觉;远期并发症及生活质量问卷调查。对术前计数资料行χ2检验;对所有计量数据资料先行正态分布检验,符合正态分布的术前数据再行方差齐性检验和单因素方差分析;对术后不同的指标评价时先行3组间非参数Kruskal-Wallis检验;有差异者两两组间再行非参数Mann-Whimey U检验比较。结果术后1年、3年和5年,非球面多焦点组裸眼中视力[0.30(0.10,0.50)、0.30(0.10,1.00)、0.30(0.10,0.50)]优于非球面组[0.40(0.10,0.70)、0.40(0.20,1.00)、0.40(0.20,0.50)],差异有统计学意义(Z1=-3.32、-1.73、-3.01,P1=0.00、0.01、0.00);亦优于球面组[0.40(0.30,1.00)、0.40(0.20,1.00)、0.40(0.20,1.00)],差异亦有统计学意义(Z2=-5.77、-3.19、-4.49,P2=0.00、0.00、0.00);非球面多焦点组裸眼近视力[0.25(0.00,1.00)、0.30(0.00,1.00)、0.30(0.00,1.00)]优于非球面组[0.50(0.18,1.00)、0.50(0.18,1.00)、0.50(0.18,1.00)],差异有统计学意义(Z1=-5.57、-5.37、-4.93,P1=0.00、0.00、0.00);亦优于球面组[0.60(0.18,1.00)、0.60(0.18,1.00)、0.60(0.18,1.00)],差异亦有统计学意义(Z2=-7.00、-6.91、-6.53,P2=0.00、0.00、Objective To observe the clinical effect of long term visual quality after the implantation of the aspheric diffractive multifocal intraocular lens.MethodsThis was a retrospective cohort study.One hundred and thirty cases of age-related cataract (170 eyes) after phacoemulsification cataract extraction combined with IOL implantation were collected from September of 2009 to January of 2011 in the First Affiliated Hospital of Zhengzhou University.There were 42 patients (57 eyes) with aspheric multifocal group, 43 patients (57 eyes) in the aspheric group and 45 patients (56 eyes) in the spherical group according to the different types of IOL implanted.At 1 year, 3 years and 5 years after operation, the following parameters were assessed: uncorrected and best corrected distance, medium and near vision acuity, contrast sensitivity, wavefront aberrations, modulation transfer functions (MTF), stereopsis, visual function and quality of life (VF/QOL) questionnaire survey.ResultsAt 1 year, 3 years and 5 years after operation, the uncorrected medium visual acuity in aspheric diffractive multifocal IOL group(0.30(0.10, 0.50), 0.30(0.10, 1.00), 0.30(0.10, 0.50)) was better than that of eyes in aspheric IOL group(0.40 (0.10, 0.0), 0.40 (0.20, 1.00), 0.40 (0.20, 0.50)) (Z1=-3.32,-1.73,-3.01, P1=0.00, 0.01, 0.00) and spherical IOL group (0.40(0.30, 1.00), 0.40(0.20, 1.00), 0.40(0.20, 1.00)) (Z2=-5.77,-3.19,-4.49, P2=0.00, 0.00, 0.00).And the near vision in aspheric diffractive multifocal IOL group(0.25(0.00, 1.00), 0.30(0.00, 1.00), 0.30(0.00, 1.00)) was also obviously better than that of eyes in aspheric IOL group (0.50(0.18, 1.00), 0.50(0.18, 1.00), 0.50(0.18, 1.00)) (Z1=-5.57,-5.37,-4.93, P1=0.00, 0.00, 0.00) and spherical IOL group(0.60(0.18, 1.00), 0.60(0.18, 1.00), 0.60(0.18, 1.00)) (Z2=-7.00,-6.91,-6.53, P2=0.00, 0.00, 0.00). At 5 years after operation, the mean higher-order aberration f
