方法：通过睫状肌麻痹检影验光及光学生物测量仪(IOL-Master)获得44例88眼的屈光不正度数、眼轴、角膜屈光力、前房深度等参数，经计算得到晶状体度数。按屈光不正度数分为远视组、正视组、近视组，直线相关与回归比较年龄和屈光不正与各屈光参数之间的关系。

结果：受试者44例88眼，平均年龄9.04±2.39岁，等效球镜(SE)-3.50～+8.75D； 远视组眼轴比近视正视组短(P<0.05)，远视组晶状体屈光力明显低于近视正视组(P<0.05)，三组间角膜屈光力和前房深度无明显差别。本研究发现年龄与等效球镜(SE)之间成负相关； 眼轴与年龄成正相关； 年龄与晶状体屈光力成正相关； SE与眼轴成负相关； SE与晶状体屈光力有负相关关系。

结论：儿童随年龄增长，SE向近视发展，眼轴变长，晶状体屈光力增强； SE越偏远视，眼轴越短、晶状体屈光力越弱。

METHODS:Totally 44 children 88 eyes with refractive error who underwent retinoscopy with cycloplegia, to be measured spherical equivalent refractive error. Axial length was measured by a noncontact optical biometry(ZEISS IOL-Master), and corneal K and anterior chamber depth(ACD)were also measured by the same machine. The refractive power of the lens was calculated by using the SRK formula. The patients were divided into 3 groups, myopia(SE<0), hyperopia(SE>+0.50D)and emmetropia(0 to +0.50D). Linear Correlation and Regression were used to evaluate the correlation among the optical parameters.

RESULTS:Totally 44 subjects, 88 eyes, average 9.04±2.39 years, spherical equivalent(SE)-3.50D to +8.75D. Hyperopic AL was shorter than the other two groups(P<0.05), same trend in lens power. No significant differences among the 3 groups in corneal K and ACD. There was a negative correlation between age and SE, SE and AL, SE and lens refractive power, and there was a positive correlation between age and AL, age and lens power.

CONCLUSION:As the children's growing up, SE trends to myopia, and AL becomes longer, and lens power is stronger.
