中文摘要：

目的通过观察行飞秒激光辅助白内障手术联合Restor＋2.5 D和Restor＋3.0 D多焦点人工晶状体（MIOL）双眼植入术后3个月患者的双眼全程视力、对比敏感度、视觉干扰现象及主观满意度等指标,综合评价其术后视觉质量及老视矫正的效果。方法连续选择自2015年3月至2017年3月就诊于重庆爱尔麦格眼科医院的双眼白内障合并老视患者105例（210只眼）,采用信封法随机分为观察组和对照组,观察组行飞秒激光辅助白内障超声乳化吸出联合双眼先后植入Restor＋2.5 D和Restor＋3.0 D MIOL,对照组行飞秒激光辅助白内障超声乳化吸出联合双眼植入Restor＋3.0 D MIOL。术后早期观察患者的并发症情况。术后3个月检查两组患者单眼与双眼的离焦曲线及对比敏感度,并填写MIOL植入术后的满意度调查问卷。裸眼远视力、对比敏感度及满意度评分采用均数±标准差（x±s）进行描述。治疗前后的组内比较采用配对t检验,观察组与对照组的组间比较采用独立样本t检验,两组间术后并发症、视觉干扰及满意度调查的比较采用卡方检验。结果观察组与对照组术后角膜水肿、高眼压及黄斑囊样水肿等并发症发生率的比较,差异无统计学意义（χ~2=0,0.10,0.84;P〉0.05）。所有患者术后裸眼远视力较术前均有明显改善,差异有统计学意义（t=1.97,P〈0.05）。观察组与对照组患者术后均获得了满意的双眼远视力,二者差异无统计学意义（t=1.02,P〉0.05）。对两组患者进行33 cm的近距离视力测试,对照组的裸眼视力较好,但组间差异无统计学意义（t=1.89,P〉0.05）。对两组患者进行67 cm的中距离视力测试,观察组视力明显好于对照组,差异有统计学意义（t=2.35,P〈0.05）。将观察组与对照组患者术后产生眩光、光晕及色差等视觉干扰现象的情况进行比较,差异均无统计学意义（χ~2=0.43,0.46,0.06;P〉0.05）。在暗视状态?

英文摘要：

Objective Through the observation of femtosecond laser assisted cataract surgery combined with Restor＋2.5 D and Restor＋ 3.0 D multifocal intraocular lens（ MIOL） implantation in eyes of patients 3 months after the whole binocular visual acuity and contrast sensitivity,visual interference and subjective satisfaction index,comprehensive evaluation of the postoperative visual quality and the effect of perception of presbyopia. Methods Continuous selection from March 2015 to March 2017 in eyes with cataract patients with presbyopia Chongqing Aier Mega Eye Hospital in 105 cases（ 210 eyes）,were randomly divided into observation group and control group using the envelope method,the observation group underwent femtosecond laser assisted phacoemulsification combined with implantation of Restor ＋ 2. 5 D and Restor＋3.0 D eyes has MIOL,the control group underwent femtosecond laser assisted phacoemulsification combined with implantation of Restor ＋ 3. 0 D MIOL eyes. The complications of the patients were observed early after operation. 3 months after surgery, the monocular and binocular defocus curves, contrast sensitivity,and satisfaction questionnaire of MIOL implantation were examined in the two groups. The uncorrected visual acuity, contrast sensitivity and satisfaction score were described by mean standard deviation（ x±s）. Before and after treatment were compared by paired t-test,the observation group compared with the control group using independent samples t-test was used to compare the complications,visual disturbance and satisfaction between the two groups by Chi Square test. Results There was no significant difference in the incidence of complications such as corneal edema,intraocular pressure and cystoid macular edema between the observation group and the control group（ χ~2= 0,0.10,0.84; P〈0.05）. The uncorrected visual acuity of all patients improved significantly compared with that before operation（ t = 1.97,P〈0. 05）.There was no significant difference in binocular distant vision
