方法：观察组为年龄相关性白内障患者20例40眼，术前角膜规则散光一眼1.50～2.50(平均2.15±0.87)D，植入散光晶状体，另一眼角膜散光<1.50D，平均0.78±0.26D，植入多焦点人工晶状体(MIOL)。对照组为同期双眼均植入MIOL的20例40眼年龄相关性白内障患者，规则角膜散光≤1.00D，平均0.62±0.34D。比较术后3mo观察组的散光晶状体眼与MIOL眼的远近裸眼视力及对照组与观察组患者双眼合视的远近裸眼视力。

结果：观察组患者Toric人工晶状体眼的裸眼远、近视力分别为0.81±0.32和0.58±0.27，MIOL眼远、近视力分别为0.76±0.28和0.67±0.24，两眼间差异无统计学意义(t=0.797，P>0.05； t=1.243，P>0.05)； 观察组双眼合视的远近视力分别为0.90±0.33和0.79±0.22，对照组双眼合视的远近视力分别为0.92±0.25和0.85±0.28，两者比较差异无统计学意义(t=0.601，P>0.05； t=0.875，P>0.05)。

结论：双眼存在程度不同角膜散光的白内障患者，一眼植入多焦点人工晶状体、另眼植入散光人工晶状体同样可以提高患者术后的脱镜率。

METHODS:Twenty patients(40 eyes)were included into the observation group. One eye with corneal astigmatism 1.50-2.50D(2.15±0.87D)was implanted astigmatic IOL(Acrysof Toric, Alcon); another eye with corneal astigmatism less than 1.50D(0.78±0.26D)was implanted MIOL. In the control group, 20 patients(40 eyes)with corneal astigmatism less than 1.00D(0.62±0.34D)were implanted MIOL in both eyes. 3 months after surgery, uncorrected distant vision and near vision with one eye and both eyes were observed in two groups.

RESULTS: In the observation group, uncorrected distant vision and near vision were 0.81±0.32 and 0.58±0.27 with Toric IOL, 0.76±0.28 and 0.67±0.24 with MIOL. There were no statistical differences(t=0.797,P>0.05; t=1.243,P>0.05). Uncorrected distant vision and near vision with both eyes were 0.90±0.33 and 0.79±0.22 in the observation group, 0.92±0.25 and 0.85±0.28 in the control group, there were no statistical differences(t=0.601, P>0.05; t=0.875, P>0.05).

CONCLUSION: MIOL and matching astigmatic IOL are good choice to increase vision without glasses for cataract patients with corneal astigmatism.
