摘　　要：目的评价AcrySof Toric人工晶状体（IOL）在长眼轴高度近视患者晶状体囊袋内的旋转稳定性。方法前瞻性病例对照研究。植入AcrySof Toric IOL的白内障患者，根据眼轴长度分为两组，正常眼轴组42例（46只眼），长眼轴组13例（17只眼），术后1d，1周，1个月，3个月散瞳记录IOL轴向。结果（1）IOL的旋转度：术后1d，正常眼轴组为（5．32±3．81）°,长眼轴组为（6．24±3．67）°,两组比较差异无统计学意义（t=0．87P〉0．05）；术后1d到1周，正常眼轴组为（0．26±0．53）°,长眼轴组为（0．35±0．61）°,两组比较差异无统计学意义（t=0．57P〉0．05）；术后1周到1个月，正常眼轴组为（1．04±0．97）°,长眼轴组（1．47±1．12）°,两组比较差异无统计学意义（t=1．50 P〉0．05）；术后1个月到3个月，正常眼轴组为（0．26±0．74）°,长眼轴组为（0．53±1．28）°,两组比较差异无统计学意义（t=1．00P〉O．05）。（2）裸眼视力：正常眼轴组术前：〈0．1为20只眼，0．1-0．3为26只眼；术后3个月：0．4～0．6为10只眼，0．7～0．9为22只眼，≥1．0为14只眼。术前术后比较差异有统计学意义（Fisher’s exact=92．00，P〈O．05）。长眼轴组术前：〈0．1为12只眼，0．1—0．3为5只眼；术后3个月：0．1-0．3为1只眼，0．4～0．6为9只眼，0．7～0．9为5只眼，≥1．0为2只眼；术前术后比较差异有统计学意义（Fisher’s exact=30．67，P〈0．05）。（3）散光度数：正常眼轴组术前：（-1．97±0．53）D，术后：（-0．56±0．25）D，术前术后比较差异有统计学意义（t=14．38，P〈0．05）。长眼轴组术前：（-2．06±0．56）D，术后：（-0．71±O．30）D，术前术后比较差异有统计学意义（t=8．76，P〈0．05）。结论术后3个月内，AerySof Torie IOL在高度近视患者的大晶状体囊袋中有较好地旋转稳定性。Objective To evaluate the rotational stability of AcrySof Toric Intraocular lenses （IOL） in the capsular bag with long axial length. Methods A prospective case control study. Fifty-five patients who were performed cataract extraction and AcrySof Toric IOL implantation were included. They were divided into two groups according to axial length, normal axial length group included 42 patients （46 eyes） and long axial length group included 13 patients （17 eyes）. One day, 1 week, 1 month, and 3 months after IOL implantation, the AcrySof Toric IOL axis was measured. Results Rotational stability： one day after implantation, the mean AcrySof Toric IOL axis rotation was 5.32±3.81° in the normal axial length group and 6.24±3.67° in the long axial length group, there were no statistically significant differences between the two groups （t =0.87, P 〉0.05）, from one day to 1 week after implantation, the mean AcrySof Toric IOL axis rotation was 0.26±0.53° in the normal axial length group and 0.35±0.61° in the long axial length group, there were no statistically significant differences between the two groups （t =0.57, P 〉0.05）, from 1 week to 1 month after implantation, the mean AcrySof Toric IOL axis rotation was 1.04±0.97° in the normal axial length group and 1.47±1.12° in the long axial length group, there were no statistically significant differences between the two groups （t =1.50, P 〉0.05）, from 1 month to 3 months after implantation, the mean AcrySof Toric IOL axis rotation was 0.26±0.74° in the normal axial length group and 0.53±1.28° in the long axial length group, there were no statistically significant differences between the two groups （t =1.00, P 〉0.05）. The uncorrected visual acuity： for both groups, there were statistically significant differences between before and after implantation （P 〈0.05）. Refractive cylinder： for both groups, there were statistically significant differences between before and after implantation （P 〈 0.05）. Conclusions The
