方法：选择老年性白内障合并角膜散光的患者34例为研究对象，进行白内障超声乳化摘除联合Toric人工晶状体植入，观察术前和术后3mo的临床效果，包括裸眼视力(UCVA)，最佳矫正视力(BCVA)，全眼残余散光，人工晶状体转动度数，视远脱镜情况。

结果：所有患者Toric人工晶状体均成功植入。术前UCVA 0.15±0.06，术后UCVA上升至0.65±0.15(P<0.01)； 术前BCVA 0.37±0.13，术后BCVA上升至0.85±0.19(P<0.01)； 全眼散光由术前2.14±0.69D降低至0.73±0.36D(P<0.01)，97%的患者人工晶状体转位<5°，平均旋转2.6°±1.3°，术后3mo视远脱镜率达95%。

结论：Toric人工晶状体能够有效矫正白内障合并的角膜散光，晶状体在囊袋内具有良好的稳定性，提高了患者的术后视觉质量。

METHODS: In this is a retrospective observational study, 34 senile(39 eyes)cataract patients with corneal astigmatism underwent phacoemulsification combined with Acrysof toric IOL implantation. The preoperative and 3mo postoperative uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), postoperative residual astigmatism, toric lens axis, and spectacle independence were detected and compared.

RESULTS: Thirty-four patients(39 eyes)underwent phacoemulsification combined with Acrysof toric IOL implantation successfully. Preoperative UCVA was 0.15±0.06, 3mo postoperative UCVA increased to 0.65±0.15(P<0.01). Preoperative BCVA was 0.37±0.13, 3mo postoperative BCVA increased to 0.85±0.19(P<0.01).Preoperative corneal astigmatism was 2.14±0.69D and the postoperative residual astigmatism was 0.73±0.36D(P<0.01), 97% IOL rotation was <5%, the mean IOL rotation was 2.6°±1.3°, 95% patients were independence with spectacle at distance at 3mo postoperative.

CONCLUSION: Implantation of Acrysof totic IOL for correcting astigmatism is effective, the IOL has good rotation stability, and provides postoperative visual function.
