摘　　要：目的:比较超声乳化同轴3.0mm切口与2.2mm切口联合MI60型人工晶状体植入对白内障患者视觉质量的影响。方法:前瞻性病例对照研究。采用随机数字表法,将实施超声乳化年龄相关性白内障手术的患者100例100眼随机分为两组,传统3.0mm切口组50例50眼,2.2mm切口组50例50眼。观察患者术后1wk,3mo的最佳矫正视力(BCVA)、对比敏感度(CS)及手术源性散光(SIA)。并由2位工作人员在末次随访完成VF和QOL问卷调查。结果:术后1wk,3mo,两组矫正视力差异均无统计学意义(t=-1.366、-1.688,P=0.148、0.107)。2.2mm切口组在夜视(3、6c/d)及夜视加周边眩光(1.5、3、6c/d)条件下,术后1wk对比敏感度值优于3.0mm切口组,差异有统计学意义(P<0.05)。术后3mo两组对比敏感度差异无统计学意义(P>0.05)。术后1wk,3mo,2.2mm切口组SIA分别为0.46±0.29、0.43±0.26D;3.0mm切口组SIA分别为1.55±0.59、0.89±0.28D,两组差异具有统计学意义(t=-7.348、-3.788,P=0.000、0.000)。两组病例平均VF得分差异无统计学意义,但视觉适应一项得分2.2mm切口组优于3.0mm切口组,差异具有统计学意义(t=-3.348,P<0.05)。结论:同轴2.2mm切口超声乳化联合人工晶状体植入较同轴3.0mm切口治疗年龄相关性白内障手术相比,能有效减少SIA,且视觉适应性更优,具有更佳的视觉质量。AIM：To study and compare the outcomes of coaxial 2. 2 mm phacoemulsiflcation with conventional coaxial 3 mm small-incision cataract surgery. METHODS： A randomized prospective study was conducted on 100 patients with age - related cataract：coaxial 2. 2 mm micro - incision cataract surgery was performed in 50 cases （50 eyes）, and coaxial 3 mm small incision cataract surgery was performed in 50 cases （ 50 eyes） . Statistical analysis was takenwith the data of the two groups. Visual acuity, VF and QOL were compared at intervals of 1wk and 3mo after surgery. In addition, surgically induced astigmatism （ SIA ） was analyzed. Statistic analysis was taken by Student＇s t-test and Chi-square test. RESULTS：There was no significant difference on BCVA （t=-1. 366, -1. 688; P=0. 148, 0. 107） between these two groups. One week and 3mo after the surgery, SIA was （0. 46±0.29）D, （0. 43±0. 26）D in the 2. 2 group; and （1. 55±0. 59） D, （0. 89±0. 28） D, in 3. 0 group. The differences between these two groups were statistically significant （ t=-7. 348, -3. 788; P = 0. 000, 0. 000 ） There were no statistically significant differences on VF scores between two group, while it＇s got a better score in 2. 2 groups on vision adaptation. （t=-3. 348, P〈0. 05）. CONCLUSION：Coaxial 2. 2mm micro-incision cataract surgery could significantly reduce SIA and obtain morestable status of VF and QOL. This suggests that the coaxial 2. 2 phacoemulsification surgery implanted AkreosMI60 intraocular lens could get earliervisual rehabilitation postoperation.
