目的 评价Acrysof Toric人工晶状体矫正白内障伴角膜散光患者的远期临床效果及其在囊袋内的旋转稳定性.方法 回顾性非随机临床研究.选取在浙江大学医学院附属第一医院眼科已行白内障超声乳化吸除联合Acrysof Toric人工晶状体植入术的白内障患者21例(23眼),年龄53～84岁,均为术后24个月以上.观察术前术后的裸眼视力(UCVA)、最佳矫正视力(BCVA),术前角膜散光、总散光,术后角膜散光、残留散光,人工晶状体轴位等.术前术后比较采用配对t检验.结果 术后最后一次随访时,患眼的UCVA (logMAR)为0.16±0.13,BCVA( logMAR)为0.06±0.09.术前总散光(-2.98±1.22)D,术后残留散光(-0.57±0.78)D,两者比较差异有统计学意义(t=6.371,P＜0.05).术前预留散光(-0.53±0.70)D,与术后残留散光比较差异无统计学意义.术前角膜散光(2.23±1.17)D,术后角膜散光(1.89±1.22)D,两者比较差异无统计学意义.Acrysof Toric人工晶状体轴位偏离既定轴位度数平均为(2.84±2.66)°,1只术眼(4％)的人工晶状体轴位偏离7°,余术眼(96％)的人工晶状体轴位偏离均≤5°.结论 白内障超声乳化术后植入Acrysof Toric人工晶状体具有良好的远期临床效果和旋转稳定性,是一种安全、有效、预测性好的治疗伴角膜规则散光白内障的方法.
目的 評價Acrysof Toric人工晶狀體矯正白內障伴角膜散光患者的遠期臨床效果及其在囊袋內的鏇轉穩定性.方法 迴顧性非隨機臨床研究.選取在浙江大學醫學院附屬第一醫院眼科已行白內障超聲乳化吸除聯閤Acrysof Toric人工晶狀體植入術的白內障患者21例(23眼),年齡53～84歲,均為術後24箇月以上.觀察術前術後的裸眼視力(UCVA)、最佳矯正視力(BCVA),術前角膜散光、總散光,術後角膜散光、殘留散光,人工晶狀體軸位等.術前術後比較採用配對t檢驗.結果 術後最後一次隨訪時,患眼的UCVA (logMAR)為0.16±0.13,BCVA( logMAR)為0.06±0.09.術前總散光(-2.98±1.22)D,術後殘留散光(-0.57±0.78)D,兩者比較差異有統計學意義(t=6.371,P＜0.05).術前預留散光(-0.53±0.70)D,與術後殘留散光比較差異無統計學意義.術前角膜散光(2.23±1.17)D,術後角膜散光(1.89±1.22)D,兩者比較差異無統計學意義.Acrysof Toric人工晶狀體軸位偏離既定軸位度數平均為(2.84±2.66)°,1隻術眼(4％)的人工晶狀體軸位偏離7°,餘術眼(96％)的人工晶狀體軸位偏離均≤5°.結論 白內障超聲乳化術後植入Acrysof Toric人工晶狀體具有良好的遠期臨床效果和鏇轉穩定性,是一種安全、有效、預測性好的治療伴角膜規則散光白內障的方法.

Objective To evaluate the long-term clinical efficacy and rotational stability of the Acrysof Toric intraocular lens (IOL) in correcting preoperative astigmatism in cataract patients.Methods This retrospective and nonrandomized 24-month or longer follow-up study included 23 eyes of 21 patients having phacoemulsification cataract surgery with implantation of an Acrysof Toric IOL.The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), preoperative corneal astigmatism, preoperative refractive cylinder, residual refractive cylinder, postoperative corneal astigmatism and Toric IOL axis were measured.Preoperative and postoperative data were compared with a paired t test.Results The UCVA (logMAR) was 0.16±0.13 and BCVA (logMAR) was 0.06±0.09at final follow-up.The mean refractive cylinder decreased significantly after surgery from (-2.98±1.22)Dto (-0.57±0.78)D (t=6.371, P＜0.05).There was no significant difference between preoperative [(-0.53±0.70)D] and postoperative corneal astigmatism.The anticipated residual refractive cylinder and the virtual refractive cylinder showed no statistical difference.The mean rotation of the Toric IOL was 2.84°±2.66° at final follow-up.One eye (4％) had an IOL rotation of 7°,the remaining eyes (96％) had an IOL rotation of less than 5°.Conclusion The results indicate that Acrysof Toric IOL implantation show good long-term clinical efficacy and rotational stability.It is a safe, effective and predictable method for managing astigmatism in cataract patients.
