目的研究非球面散光型人工晶状体植入治疗合并角膜散光白内障患者的临床疗效。方法将合并角膜规则散光〉1 D的年龄相关性白内障患者117例（158眼）分为两组,行超声乳化白内障吸出术后,Toric组69例（92眼）联合植入非球面散光型人工晶状体,对照组48例（66眼）联合植入非球面人工晶状体,术后比较两组患者的自觉症状、视力、全眼散光、客观视觉质量等指标。结果平均随访15.2月。术后3个月时,Toric组的全眼散光（0.65±0.38）D明显小于对照组（1.84±0.46）D,Toric组的裸眼视力（0.80±0.23）明显高于对照组（0.59±0.14）,Toric组对比敏感度、MTF cut off值、100%对比度下视力、20%对比度下视力及患者主观视觉质量的改善程度均优于对照组。Toric组在末次随访时人工晶状体旋转（7.1±4.2）°。结论非球面散光型人工晶状体可以为合并角膜散光的白内障患者提供良好的术后主观、客观视觉质量。

英文摘要：

Objective To research the clinical efficacy of aspheric Toric intraocular lens（ IOL） in the treatment of cataract patients with corneal astigmatism. Methods One hundred and seventeen age-related cataract patients（ 158 eyes） with more than 1. 0 diopter（ D） of preexisting corneal astigmatism were divided into two groups. The Toric group（ 92 eyes in 69 cases） received the aspheric Toric IOL implantation after phacoemulsification,and the control group（ 66 eyes in 48 cases） received the aspheric IOL. The postoperative symptoms,uncorrected visual acuity（ UCVA）,total astigmatism and objective visual quality indicators were examined. Results With an average followup of 15. 2 months,the total astigmatism in the Toric group（ 0. 65 ± 0. 38） D was significantly lower than that in the control group three months after the operation（ 1. 84 ± 0. 46） D,while the UCVA in Toric group（ 0. 80 ± 0. 23） was higher than that in the control group（ 0. 59 ± 0. 14）. The postoperative contrast sensitivity,MTF cut off value,visual acuity at 100% contrast,visual acuity at 20% contrast and the improvement of subjective visual quality in the Toric group were higher than those in the control group. The mean rotation of IOLs in the Toric group was（ 7. 1 ± 4. 2） degrees. Conclusion Aspheric Toric IOL can provide good subjective and objective visual quality for cataract patients with corneal astigmatism.
