方法：选择我院视光门诊远视性屈光不正的6～12岁儿童95例190眼，且双眼屈光度差值(△_SE)1D≤△_SE<2.0D和矫正视力不等，但每一眼的矫正视力均在同龄儿童正常范围内，即均非弱视。随机分为两组：A组48例，给屈光度较高眼(视力较差眼)配戴RGP，另一眼不戴镜处理； B组47例，不配镜作为对照组。用1%环戊酮散瞳验光计算等效球镜(SE)，测量眼轴(AL)，并随访1.5a。分别计算A组和B组等效球镜差值(△_SE)、眼轴差值(△_AL)，进行统计学分析。

结果：A组双眼之间等效球镜度差值(△_SE)小于B组，差异有统计学意义(F=18.508，P=0.002<0.05)； A组双眼之间眼轴差值(△_AL)小于B组，差异有统计学意义(F=1116.765，P=0.000<0.05)。

结论：在非弱视性远视屈光不等儿童中，用RGP矫正高屈光度眼视力是有必要的，可以明显减少双眼屈光度、矫正视力差异，避免屈光参差所带来的视觉功能异常等一系列问题。

METHODS:In department of optometry in our hospital, 95 children 190 eyes aged from 6～12 year-old with hyperopic refractive error, of whom the difference of spherical equivalent between two eyes was 1D≤△_SE<2.0D and whose corrected vision was different, but the corrected visual acuity of either right eye or left eye was within the normal range of children with the same age, which meant the difference was non-amblyopia. The patients were randomly divided into two groups:48 cases in group A, in which group the eye with stronger diopter(poorer eye sight eye)wore RGP, the other eye without wearing lenses; 47 cases in group B, in which group children did not wear lenses as a control group. Cyclopentanone with 1% concentration was used to mydriasis, then spherical equivalent(SE)refraction was calculated, the axial length(AL)was measured, and follow-up lasted for 1.5a. The △_SE and △_AL of the two groups were calculated and analyzed statistically.

RESULTS:The △_SE between two eyes of group A was less than that of group B, and the difference was statistically significant(F=18.508,P=0.002<0.05); the △_AL between two eyes of group A was less than that of group B, the difference was statistically significant(F=1116.765,P=0.000<0.05).

CONCLUSION:In children with non-amblyopia anisometropia, RGP is very necessary to correct the vision of higher-dioptry eye. And it can significantly reduce the binocular refraction, correct anisometropia, avoid visual function abnormalities caused by anisometropia and so on.
