方法：对90例180眼近视儿童分为3组：不戴镜组30例，低矫组(单眼矫正<1.0)30例及全矫组(单眼矫正至1.0)30例，所有患儿均用复方托品酰胺进行睫状肌麻痹验光，次日复验配镜。1a后，复方托品酰胺进行睫状肌麻痹验光，屈光度以单眼矫正至1.0为标准。观察屈光度的改变。

结果：各组患者近视屈光度均逐年增加，增加度数全矫组明显低于不戴镜组及低矫组，低矫组明显低于不戴镜组。

结论：不同程度的屈光矫正及未矫正对近视患者屈光演变过程有影响，欠矫及未矫正均可加速近视的进展。

METHODS: Totally 90 young myopia patients 180 eyes were divided into 3 groups: group A without glasses(30 children); group B monocular correction <1.0(30 children); group C binoculus correction=1.0(30 children). All patients were subjected to cycloplegic refratometry by compound tropicamide and reinspected the next day. One year later, all patients were subjected to cycloplegic refratometry again to observe the change of myopia number. The diopter took monocular correction to 1.0 as standard.

RESULTS: All patients' myopia increased year by year, the increase of diopter in group C was significantly lower than that of group A and B, and group B was significantly lower than group A.

CONCLUSION: Different degrees correction and uncorrection of refractive error will affect the refraction evolution process, under-correction or uncorrection will increase the myopic development.
