摘　　要：目的 探讨Canon Staar KS-3Ai非球面人工晶状体及Canon Staar KS-3球面人工晶状体植入术后，两组之间人眼波前像差的差异。方法 老年性白内障患者71例（80眼），随机分为两组，每组40眼，行超声乳化白内障吸除术联合人工晶状体植入术，分别植入Canon Staar KS-3Ai非球面人工晶状体及CanonStaarKS-3球面人工晶状体，术后3个月做波前像差检查。测量人工晶状体眼的球差、第三、第四、第五、第六阶像差及总体高阶像差，对检查结果进行T检验。结果 瞳孔直径在5．0mm状态下Canon Staar KS-3Ai非球面人工晶状体组的球差、第四、第五、第六阶像差及总体高阶像差均明显低于Canon Staar KS-3球面人工晶状体组，两组间差异具有统计学意义（P〈0．05）.结论 非球面人工晶状体眼视觉质量明显优于球面人工晶状体眼。Objective To compare wavefront aberration in pseudophakic eyes with two different types of intraocular lenses （IOLs） implantation in order to obtain an objective evaluation of the optical quality of these pseudophakic eyes. Methods 71 patients （80 eyes） were selected randomly to accepted phacoemulsification and implanted IOLs of Canon Staar KS-3 and Canon Staar KS-3Ai. Examine the Spherical Aberration, RMS4, RMSS, RMS6 and RMSh at 3 months after cataract surgery. Results For a 5.0mm optical zone, the Spherical Aberration, RMS4, RMSS, RMS6 and RMSh in eyes implanted with Canon Staar KS-3Ai showed significant reduction（P〈0.05）. Conclusion Our study shows the optical quality of eyes implanted with aspheric IOLs was significantly better than spherical IOLs.
