双眼角膜散光白内障分别植入多焦IOL和散光IOL的临床观察

目的：观察双眼存在不同程度角膜散光的白内障患者分别植入多焦点人工晶状体、散光人工晶状体的临床效果。

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。

Multifocal intraocular lens and matching astigmatic intraocular lens for cataract patients with corneal astigmatism

AIM: To observe clinical results of multifocal intraocular lens(MIOL)and matching astigmatic intraocular lens(IOL)for cataract patients with corneal astigmatism.

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.
