目的.研究澳大利亚年轻人群的等效球镜屈光度和眼生物特征参数的分布。采用非接触式方法，在分层随机整群抽样的1年级悉尼学校的学生（n = 1765），平均年龄6.7岁（范围，5.5 - 8.4岁）的眼睛尺寸和睫状肌麻痹自动验光。对每只眼睛重复测量眼轴长度、前房深度以及最大和最小角膜曲率半径（分别为CR 1、CR2）。屈光度测量为等效球镜。右眼的平均等效球镜屈光度为+ 1.26 +/- 0.03 D（SEM;范围：- 4.88至+ 8.58）。分布呈峰值（峰度14.4）并略微向右偏斜（偏斜度1.7）。近视患病率，定义为等效球镜屈光度
PURPOSE. To study the distribution of spherical equivalent refraction and ocular biometric parameters in a young Australian population.METHODS. Noncontact methods were used to examine ocular dimensions and cycloplegic autorefraction in a stratified random cluster sample of year 1 Sydney school students ( n = 1765), mean age 6.7 years ( range, 5.5 - 8.4 years). Repeated measures of axial length, anterior chamber depth, and greatest and least corneal radius of curvature (CR1, CR2, respectively) were taken in each eye. Refraction was measured as the spherical equivalent.RESULTS. Mean spherical equivalent refraction in right eyes was + 1.26 +/- 0.03 D ( SEM; range, - 4.88 to + 8.58). The distribution was peaked (kurtosis 14.4) and slightly skewed to the right (skewness, 1.7). Prevalence of myopia, defined as spherical equivalent refraction
