摘　　要：目的:探索以屈光要素角膜屈折力CD(cornea diopter)、前房深度ACD(anterior chamber depth)、晶状体厚度LENS(lens thickness)、玻璃体腔深度VITR(vitreous depth)、眼轴长度AL(ocular axis longitude)的生物测量值推算高中生眼屈光度的方法。方法:采取整群抽样的方法对某中学高中部高一至高三的182例364眼学生进行眼相关检查,用电脑验光获得屈光度,用角膜曲率计及A超测得屈光要素生物测量值。以SPSS软件分析剔除不相关要素,得出屈光度、相关屈光要素间关系的多元线性回归方程。结果:屈光度D与相关屈光要素CD,ACD,LENS,VITR间关系的多元线性回归方程是D=69.750-0.724×CD-0.630×ACD-2.207×LENS-1.728×VITR(r=0.87)。结论:高中生眼屈光度D可以用CD,ACD,LENS和VITR间接推算。AlM： To explore a formula between the diopter , cornea diopter （ CD ） , anteriou chamber depth （ ACD ） , lens thickness （ LENS ） , vitreous depth （ VlTR ） , and ocular axis longitude （ AL ） of high school students in certain middle school, and to predict the diopter with the biometry data of refractive factors on the students. METHODS： The related ocular examinations were performed to 364 eyes of 182 high school students in certain middle school by cluster sampling method. Optometry was for diopter and A-ultrasonic biometry was for ACD, LENS, VlTR, and AL. The data were analyzed with SPSS to sum up a poly-variation liner regression formula that can express their quantitative relationship.RESULTS： A poly-variation liner regression was got. The formula was D=69. 750-0. 724×CD-0. 630×ACD-2. 207×LENS-1. 728×VlTR （r=0. 87）.CONCLUSlON： The diopter of high school students seems able to be predicted through biometric data of CD, ACD, LENS and VlTR.
