Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。
