本文作者对５７２例（１１４４只眼）患者拟行ＲＫ手术前对角膜不同部位厚度进行了测量，对其中央厚度作统计学处理，均值及标准差为０．５２７±０．０３７ｍｍ标准误为０．００２，说明我国９５％的近视眼患者中央角膜厚度范围在０．４５５－ｌ６００ｍｍ之间。ｔ检验，Ｐ＞０．０５，相差均无显著性。提示我国成人各年龄组左、右眼角膜厚度与左、右眼屈光度、性别、眼别等之间无关。强调ＲＫ手术前角膜测厚的重要性，但手术预后优劣为多因素所致。
In 572 patients (1144 eyes), the authors measured the thickness of different parts of the cornea before RK surgery. The central thickness was statistically analyzed. The mean and standard deviation were 0.527 ± 0.037 mm, and the standard error was 0 .002, indicating that 95% of myopia in patients with central corneal thickness range between 0.455-l600mm. t test, P> 0.05, the difference was not significant. Tip of the age of our country adults left and right corneal thickness and the left and right eyes refraction, sex, eye and so has nothing to do. Emphasis on the importance of corneal thickness measurement before RK surgery, but the prognosis of surgery is due to multiple factors.
