目的 :探讨 L ASIK手术治疗屈光不正术前患者的 ORBSCAN（ ORB）与超声角膜测厚仪 （ A超 ）测量值的相关性 ,并给出术前 A超预测值的回归公式。方法 :分别应用 ORB与 A超测量 74眼 L ASIK术前患者的中央角膜厚度 ,对两组测量值进行配对 t检验、直线相关及回归分析 ,并利用回归方程对 L ASIK术前 A超测量值进行预测。结果 :两组测量值之间有非常显著差异 （ P

Objective: To compare the data of corneal thickness measured with Orbscan Topography System (ORB) and DGH-4000 ultrasonic pachymetry. Methods: Measurement was assessed in 74 eyes using both ORB and UP. Using Software of SPSS, corneal thickness was compared using paired samples t-test. The relationship between the devices was assessed by analysis of regression (ANOR). Results: In the measurement, the mean values of corneal thickness from different instruments were significantly different (P
