摘　　要：目的评价新型＋3．00D非球面ReSTOR人工晶状体（IOL）植入术后的功能性视力，并与＋4．00D非球面ReSTORIOL进行对比。方法病例财照研究。选取2009年1月至2010年12月在天津医科大学眼科中心行超声乳化白内障吸除手术的患者60例（120只眼），分为2组，分别植入＋3．00D非球面ReSTOR（＋3．00D组）和＋4．00D非球面ReSTORIOL（＋4．00D组）。术后6个月检查两组患者的对比敏感度以及在不同照度（100cd／m2和6cd／m2）下的裸眼远视力、最佳矫正远视力、最佳近视力、60cm中距离视力，并进行离焦曲线的绘制以及脱镜率和患者满意度的涮金。采用独立样本t检验进行统计学分析。结果＋3．00D组患者在照度为100cd／m2（6cd／m2）下的裸眼LogMAR远、中、近视力分别为0．10（0．24）、0．24（0．41）、0．14（0．41），＋4．00D组患者则分圳为0．09（0．23）、0．42（0．48）、0．15（0．36）。两组仅在中距离视力上的差异具有统计学意义（t=3．476，P=0．001）。＋3．00D组的近点远移了7cm。＋3．00D组和＋4．00 D组分别有76％（23／30）、73％（22／30）患者在日常生活中不需戴镜，两组均未发现明显的视觉十扰现象。与＋4．00D非球面ReSTORIOL相比，＋3．00D非球面ReSTOR IOL提高了中距离视力。Objective To evaluate the visual outcome of ＋ 3.00 D aspheric intraocular lens （IOL） implantation and compare it with the previous ＋ 4. 00 D aspheric AcrySof ReSTOR multifi）cal IOL. Method It was a case-control study. Sixty patients （120 eyes） from the Tianjin Medical University Eye Center between Jan. 2009 and Dee. 2010 were enrolled into two groups. Twenty patients were assigned to each group respectively. Parameters analyzed included contrast sensitivity, distance uncorrected and best- corrected visual acuity, distance corrected near visual acuity, intermediate visual acuity （60 cm） under bright light condition （100 cd/m2） and dim light condition （6 ed/m2）, through-focus measurement, spectacle independence survey 6 months after second-eye surgery, lndepemlent-samples t tests were used to statistically analyze. Results In the ＋ 3.00D ReSTOR group, LogMAR visual acuity in bright （dim） light was 0. 10 （0. 24）, 0. 24 （0. 41 ）, 0. 14 （0. 41 ） at distant, intermediate and near distance, respectively. While in the ＋4. 00 D ReSTOR group, it was 0. 09 （0. 23）, 0. 42 （0. 48）, 0. 15 （0. 36）, respectively. There was significant difference at intermediate vision between these two groups （P =0. 001 ）. The best near distance was approximately 7 cm out in the ＋ 3.00 D IOL group. The percentages of patients not wore glasses for daily activities in ＋ 3.00 D and ＋ 4. 00 D ReSTOR groups were 76% （23/30） and 73% （22/30） , respectively. No significant visual interference problems were noted in both groups. Conclusion The ＋ 3.00 D aspheric AcrySof ReSTOR IOL achieves a more satisfactory intermediate distance vision when compared with the ＋ 4.00 D aspheric IOL.
