方法：选择2013-06/2014-07在我院进行超声乳化白内障吸出及人工晶状体植入术合并角膜散光的白内障患者38例46眼作为研究对象，其中20例24眼患者植入Toric人工晶状体，18例22眼患者植入Acrysof IQ人工晶状体，对两组患者的临床疗效进行分析。

结果：两组患者术后裸眼视力进行比较，差异有统计学意义(F=5.783，P<0.05)； 观察组患者术后1wk，1、3mo裸眼视力明显高于术前，其差异均有统计学意义(P<0.05)； 观察组患者术后裸眼视力明显高于对照组，其差异有统计学意义(t=5.248，2.573，2.782； P均<0.05)。两组患者术后散光情况进行比较，差异有统计学意义(F=5.482，P<0.05)； 观察组患者术后1wk，1、3mo的散光改善情况明显优于手术前，其差异有统计学意义(P<0.05)； 观察组患者术后散光改善情况明显优于对照组，其差异有统计学意义(t=6.591、3.287、2.167，P均<0.05)。远视力研究中植入Toric人工晶状体有75%的患者不需要配戴眼镜。

结论：Toric人工晶状体植入治疗白内障合并角膜散光具有良好的矫正作用，且能明显提高患者术后视觉治疗，有良好的预测性，因此值得在临床推广应用。

METHODS: Thirty-eight patients(46 eyes)with corneal astigmatism undergone phacoemulsification and IOL implantation in our hospital from June 2013 to July 2014 were observed. Twenty cases(24 eyes)received Toric IOL, 18 cases(22 eyes)got Acrysof IQ IOL. The clinical efficacy of the two groups was analyzed.

RESULTS:The difference on visual acuity after surgery between the two groups was statistically significant(F=5.783, P<0.05). The uncorrected visual activity of the observed group after 1wk, 1 and 3mo was significantly higher than that before the operation, the difference was statistically significant(P<0.05); The uncorrected visual activity of the observed group was significantly higher than that in the control group, the difference was statistically significant(t=5.248, 2.573, 2.782; all P<0.05). The difference on the degree of astigmatism after surgery between the two groups was statistically significant(F=5.482, P<0.05). At 1wk, 1 and 3mo after the operation treatment, the degree of astigmatism in the observed group was lower than that before operation, the difference was statistically significant(P<0.05); The degree of astigmatism in the observed group was lower than that in the control group, the difference was statistically significant(t=6.591, 3.287, 2.167; all P<0.05). The results of distance vision study suggested that 75% patients with IOL implantation do not need to wear spectacles.

CONCLUSION: Phacoemulsification associated with Toric IOL implantation has good correction effect and prediction for cataract and corneal astigmatism patients, and can improve the visual activity significantly, so it is worthy of clinical application.
