摘　　要：目的观察近视性屈光参差患者双眼高阶像差（higher order aberrationsHOA）的异同。方法用NIDEK公司的OPD—Scan波前像差仪与角膜地形图ARK-10000对双眼屈光参差≥2．0DS的近视患者进行像差检查，分别对高度数眼组和低度数眼组之高阶像差进行分析并比较。结果高度数眼组与低度数眼组的高阶像差，球差，彗差相比均无统计学意义（P〉0．05）.高阶像差，球差，彗差与近视屈光度均无明显相关性（P〉0．05）.结论近视性屈光参差患者双眼的高阶像差，球差，彗差与屈光度无关。Objective To observe the similarities and differences of higher order aberrations in both eyes of anisometropia. Methods Using the Nidek OPD-Scan （ Nidek,Gamagori, Japan） aberrometer ,the aberrations was performed on 27 anisometropic cases whose refractive difference between both eyes was greater than 2.0DS, and then the difference of higher order eberrations between both eyes was compared and analyzed. Results There was no statistical difference of high order aberration, spherical aberration and coma between the high refraction eye and the low refraction eye （P 〉 0.05）. High order aberration,spherical aberration and coma all have no distinguished correlation to diopeter （P 〉 0.05）.Conclusions High order aberration, spherical aberration and coma of myopic anisometropia seemed not related to diopter.
