目的：评估角膜地形图引导的陡轴切口和Toric晶状体对白内障合并角膜散光治疗的临床疗效。方法回顾分析对2013年1月至2014年12月白内障合并角膜散光患者52例（66只眼）A术式术后的裸眼视力、角膜散光情况，B术式术后的裸眼视力、总合散光及Toric晶状体在囊袋内的稳定性。结果 A术式术后各时间点裸眼视力与术前比较提高，术后1周、1个月、3个月与术前相比，散光度均明显减小（ P ＜0）；B术式后各时间点裸眼视力均显著高于术前，术后1周、1个月、3个月全部眼总合散光明显改善（ P ＜0），最大IOL旋转度未超过4°。结论角膜地形图引导的陡轴切口和Toric晶状体植入是治疗白内障合并角膜散光易行、安全、有效的治疗方法。

Objective To evaluate the clinical efficacy of topography-guided steep corneal cuts and Toric intraocu-lar lens implantation for the treatment of corneal astigmatism in cataract patients.Methods This is a retrospective obser-vational study.Author enrolled 52 patients (66 eyes) who had cataract and corneal astigmatism.Patients received either to-pography-guided steep corneal cut ( group A;40 patients, 50 eyes) or standard corneal cut with AcrySof Toric IOL implan-tation ( group B;12 patients, 16 eyes) .Uncorrected visual acuity, astigmatism and Toric IOL rotational stability were eval-uated.Results In both groups, postoperative uncorrected visual acuity improved significantly at 1 week, 1 month, and 3 months after surgery ( P <0.05).Astigmatism also significantly reduced in both groups after the surgery ( P <0.05).In group B patients, the largest IOL rotation did not exceed 4°.Conclusion The topography-guided steep corneal cuts and Toric IOL implantation for cataract patients with astigmatism is an easy, safe, and effective treatment.
