Our present study was to investigate the corneal posterior surface topography in different clinical stages of keratoconus.
目的分析各期圆锥角膜后表面的形态特点，为完善圆锥角膜形态特点的描述提供参考。
The area under ROC of posterior maximum refractive power and the AUR of posterior maximum elevation were greater than that of other indices in the diagnosis of early keratoconus.
在诊断早期圆锥角膜中，后表面屈光度最大值、后表面高度最大值的ROC曲线下面积最大。
