目的：比较亲水性球面和非球面人工晶状体(intraocular lenses, IOL)对术后高阶像差(higher order aberrations, HOA)的影响。 方法：66例78眼行白内障超声乳化术并顺利植入球面Softec或者非球面Ocuva人工晶状体。术前和术后第3mo使用VISX Wavescan像差计进行像差测量与比较。 结果：两组间统计学无显著性差异。术后的高阶像差均方根值(root-mean-square, RMS)：Softec组0.27±0.11，Ocuva组0.28±0.13，球面像差（spherical aberration, SA）：Softec组0.11±0.07，Ocuva组0.11±0.08。 结论：与球面Softec人工晶状体比较，Ocuva非球面人工晶状体似乎没有减少术后高阶像差的优势。

AIM: To compare the effect of spherical and aspheric hydrophilic intraocular lenses (IOL) on postoperative higher order aberrations (HOA). METHODS: Uneventful phacoemulsification was performed in 78 eyes of 66 patients with implanting either spherical Softec or aspheric Ocuva lenses. Preoperative and postoperative 3rd month aberrometry was performed with Visx Wavescan aberrometer to be compared. RESULTS: There was no statistically significant difference between two groups. Postoperative root-mean-square (RMS) value of HOA: 0.27±0.11 in Softec and 028±0.13 in Ocuva group, spherical aberration (SA): 011±0.07 in Softec and 0.11±0.08 in Ocuva group. CONCLUSION: Aspheric Ocuva IOL seems not to have an advantage of decreasing postoperative HOA compared to spherical Softec IOL.
