Abstract： 目的:通过比较配戴减少周边远视离焦设计的框架眼镜(AMSPL)和普通球柱镜框架眼镜(SPL)对近视儿童眼部各参数的影响,确定AMSPL安全性和有效性.方法:随机抽取2017-07/2018-02于我院眼科中心配戴AMSPL的8～14岁近视儿童50例作为AMSPL组,同样抽取年龄、近视程度及配镜时间相当的SPL配戴者资料50例作为SPL组.检查两组患者眼压、睫状肌麻痹下的屈光状态、远距水平隐斜、近距水平隐斜、AC/A等双眼协动参数.结果:AMSPL组儿童配戴初期舒适程度略低于SPL组,主要为周边视物模糊,但1mo后两者无差异;AMSPL组屈光不正度数年平均增长-0.62±0.50D,SPL组年平均增长-0.77±0.48D(P=0.072);对于8～10岁近视儿童AMSPL组屈光不正度数年平均增长(-0.71±0.41D)低于SPL组(-1.05±0.39D),差异具有统计学意义(t=2.164,P=0.041);AMSPL组和SPL组远距水平隐斜、近距水平隐斜、AC/A等双眼协动参数无差异(P>0.05).结论:配戴AMSPL能在一定程度上延缓近视发展,尤其对于低龄近视儿童(8～10岁)效果较明显.配戴AMSPL与SPL相比眼部参数无明显变化,这表明近视儿童配戴AMSPL与SPL同样安全.
