Peripheral refraction was measured in 62 eyes along the horizontal meridian from 60 degrees nasally to 60 degrees temporally, using a Topcon refractometer. The amount of astigmatism was found to increase progressively, although less than predicted theoretically, toward the periphery in 91% of the eyes. Dividing the sample into myopes, hyperopes, and near-emmetropes showed that the type of astigmatism differed significantly with each group of eyes and that this factor played a most important role.
使用拓普康验光仪，在62只眼睛的水平子午线上，从鼻侧60度到颞侧60度测量周边屈光。结果发现，在91%的眼睛中，散光量朝着周边逐渐增加，尽管增加幅度小于理论预测。将样本分为近视、远视和近正视眼后发现，散光类型在每组眼睛中存在显著差异，且该因素起着最重要的作用。
