结局指标
主要结局
screening and diagnosis ability
时间窗: one year
Calculate the cut-off values, sensitivity and specificity of parameters measured by Pentacam, Corvis ST and Scansys in diagnosing keratoconus. Use Receiver operating characteristic curves (ROC) to analyze the optimal parameters to distinguish between the three groups.
