摘　　要：目的探讨远视儿童不同程度的屈光矫正对屈光演变的影响。方法对83例（166眼）6～9岁远视和复性远视散光的儿童散瞳验光,配镜处方根据验光度数分别减少不同球镜度数。第1组减＋1.00DS,第2组减＋2.00 DS,第3组减＋3.00 DS。连续观察3年的屈光演变。结果各组患儿的远视屈光度均逐年降低,但平均每年递减度数第1组的明显低于第2组和第3组（P〈0.01）;第2组和第3组比较差异无统计学意义（P〉0.05）。结论不同程度的屈光矫正对远视儿童的正视化过程有影响,适量欠矫有利于中、高度远视儿童的正视化过程。OBJECTIVE To evaluate the effect of refractive correction on the variation of diopter in children with hyperopia.METHODS Optometry with mydriatic was used to examine 83 patients（166 eyes） aged 6～9 years old.The diopters of all the cases were hyperopia and compound hyperopic astigmatism.The prescription of spectacles were made according to that the diopter was subtracted from different hyperopia.Thus,all the patients were divided into group 1（subtract ＋1.00？DS）,group 2（subtract ＋2.00？DS）,and group 3（subtract ＋3.00？DS）.During three years,their variation of hyperopia diopter were observed yearly.RESULTS The hyperopia diopter of each group had reduced year after year.But the average reduction of hyperopia diopter of group one was significantly lower than that of other two groups（P〈0.01）.There was no statistical difference between group 2 and 3（P〉0.05）.CONCLUSIONS Refractive corrections of different degree had effect on emmetropization of children with hyperopia.Moderate under correction was useful for emmetropization of children with hyperopia.
