目的：比较常规上方透明角膜切口与角膜地形图引导切口并植入球面人工晶状体的白内障合并角膜散光患者术后波前像差的差异。方法对我院收治的术前存在角膜散光的年龄相关性白内障患者60例，按患者入院顺序随机分入对照组与实验组，术后3个月测量两组患者术后人工晶体眼的波前像差并比较。结果波前像差检查显示：对照组总体像差（RMSg）、慧差、高阶像差（RMSh）、3阶像差（RMS3）及5～6阶像差高于实验组（P<0.01）。结论对于合并角膜散光的白内障患者，角膜地形图引导超乳切口联合人工晶状体植入可以减少人工晶体眼的慧差、高阶像差及总像差，从而提高患者的视觉质量。

Objective To compare the wavefront aberration differences of cataract patients coexisting corneal astigmatism after phacoemulsification surgery through different designed corneal incision.Methods 60 patients with corneal astigmatism were randomly divided into 2 groups,control group and experimental group. The wavefront aberration was measured and compared.ResultsThe values of RMSg,coma aberration,RMSh,RMS3,RMS5 and RMS6 of control group were obviously higher than that of experimental group.Conclusion Corneal topography guiding incision phacoemulsification surgery and the implantation of IOL can decrease the coma aberration,high-order aberration and general aberration of pseudophakic eyes.
