摘　　要：目的评估中高度角膜散光合并白内障植入非球面Toric IOL的临床疗效。方法回顾分析对2012年10月至2013年3月在北京世纪坛医院眼科就诊的20例22只眼白内障合并中高度角膜散光的患者行白内障超声乳化联合非球面Toric IOL植入术后的裸眼视力、最佳矫正视力、角膜散光情况及Toric IOL在囊袋内的稳定性。结果术后3个月裸眼视力明显好于术前矫正视力，差异有统计学意义（P〈0．05），其中裸眼视力〉／0．5的占77％。术前预计残余散光是（0．40±0．25）D、术后残余散光是（0．52±0．28）D，两者比较差异无统计学意义（P〉0．05）。术后3个月IOL旋转度数（3．69±1．35）°，最大旋转度数5°。结论中高度角膜散光合并白内障植人非球面Toric IOL是一种安全、有效并可预测治疗方法。Objective To evaluate the clinical efficacy of AcrySof SN60AT Toric IOL in correct- ing pre-operative corneal high astigmatism in cataract patients. Methods This was a retrospective observational study. This study enrolled 20 cases （22 eyes） with cataract combined high astigmatism underwent implantation of AcrySof SN60AT Toric IOL in cataract surgery. The preoperative and post- operative 3 months uncorrected distance visual acuity （UCVA） and best-corrected distance visual acu- ity （BCVA）, postoperative residual astigmatism, and IOL rotational stability after postoperative 1 week, 1 month and 3 months were evaluated. Results The postoperative 3 months UCVA was bet- ter than BCVA. 77% of eyes showed the 0.5. The postoperative residual astigmatism was 0.52＋ 0.28D and the preoperative residual astigmatism was 0.40±0.25D, there was no statistically difference between them. The mean IOL rotation was （3.69±1.35）o at 3 months follow-up. Conclusions Im- plantation of high power toric IOL in cataract surgery is a safe, effective and predictable method for correcting corneal high astigmatism.
