摘　　要：目的探讨非球面零球差及负球差人工晶状体眼高阶像差的差别，以客观评价零球差非球面人工晶状体的临床效果。方法临床病例对照研究。选取2012年10月至2013年3月在郑州人民医院眼科相继接受双眼白内障超声乳化联合零球差人工晶状体植入术的患者30例（60只眼），对照组选取同期接受双眼白内障超声乳化联合负球差人工晶状体植入术的患者30例（60只眼），并在年龄（5岁之内）、性别和眼部情况方面进行严格配对。术后3个月观察术眼的屈光状态、裸眼视力及矫正视力，并观察术眼的焦点深度。由i-trace波前像差仪测量高阶像差。运用方差分析进行统计学分析。结果二组裸眼视力及矫正视力比较无统计学意义；等效球镜比较差异无统计学意义；零球差组焦点深度〉对照组（F=1．421，P=0．046）；零球差组的球差Z（4，0）为（0．04±0．04）μm，垂直彗差Z（3，-1）为（-0．01±0．13）μm，与负球差组比较均有统计学意义（F=5．769、0．574，P=0．024、0．041，均P〈0．05），而二组水平彗差Z（3，＋1）、三叶草、总高阶像差差异无统计学意义（F=2．599、2．618、1．951，P=0．086、0．078、0．110，均P〉0．05）。结论零球差非球面人工晶状体较负球差人工晶状体相比，在有效减少球面相差的同时，可使患者保留一定的焦点深度，从而拥有更好地视觉质量。Objective To study the difference of postoperative high-order aberration and binocu-lar visual quality between two kinds of IOL： Zero Spherical Aberration Intraocular Lens （Akreos AO）, Negative spherical aberration Intraocular Lens （Tecnis ZA9003）, in order to assess the visual quality and investigate the clinical results. Methods Sixty patients （120 eyes） with cataract tender- went surgery from October 2012 to March 2013, and were divided into 2 groups. Group 1： unifocal and aspherical intraocular lens （Zero Spherical Aberration Akreos AO）, Group 2： unifocal and aspheri-cal intraocular lens （negative aberration Tecnis ZA9003）. Ocular refraction, distance visual acuity and depth of focus were observed at 3 months postoperatively. The aberrations were measured with the i-Trace wavefront aberrometer. ANOVA was used to analyze the data. Results There was no signifi-cant difference in the UCDVA and BCDVA among eyes with these IOLs. The mean spherical equiva-lent had no statistical difference between groups. The Akreos AO group was better in depth of fo-cus, the difference had statistical significance （F =1.421, P =0.046）. Spherical aberration Z（4,0） was 0.04±0.04 μm, while vertical coma Z（3,-1） was -0.01±0.13 in Akreos AO group, the difference com-paring the other group had statistical significance （P 〈0.05）. There was no difference in Z（3,＋1） （hor- izontal coma）, trefoil and total high-order aberration between the two IOL groups （P 〉0.05）. Con-clusions This study shows the evidence that Zero Spherical Aberration lens provides the patients bet-ter quality of vision because of the decreased spherical aberration and increased focus depth.
