近视儿童戴普通镜、渐进焦镜和不戴镜152例临床观察

目的：观察儿童青少年近视眼戴普通凹透镜、戴渐进多焦镜和不戴矫正镜对屈光变化的影响。方法：2007年3月～2008年12月门诊就诊的近视儿童152例（304只眼）,近视度数0.5～2.0DS,排除屈光不正以外的其他眼病,用0.5%托吡卡胺眼液扩瞳验光查出屈光度数,次日复验。随机分为三组：戴普通凹镜组53例（106只眼）,戴矫正视力=1.0的普通凹透镜;戴渐进多焦镜组51例（102只眼）,戴下加＋1.5D的渐近多焦镜片;不戴矫正镜组48例（96只眼）。6个月和12个月以后复诊,扩瞳验光复查屈光度。结果：3次屈光检查结果表明各组间比较均无显著性差异（P〉0.05）。结论：戴凹透镜或渐进多焦镜不能减缓儿童青少年近视的发展。

Clinical observation of 152 myopic children wearing ordinary lens, progressive lens and non-focal glasses

Objective：To observe the influence of general concave lens,progressive addition lenses and no corrective lens on the refractive change of children and adolescents. Methods：152 cases of out-patients myopic children（304 eyes） from March 2007 to December 2008 whose myopia extend 0.50 to 2.0 DS,excluding other eye diseases except refractive errors,was treated with 0.5% tropicamide mydriatic to detect refractive optometry. Next day the cases were randomly divided into 3 groups：53 cases（106 eyes） who wear normal concave lens of 1.0 corrected visual acuity;51 cases（102 eyes） who wear progressive multifocal lenses of ＋1.5D addition;48 cases（96 eyes） who do not wear the correct lens. And reviewed the refractive optometry 6 months and 12 months after the referral. Results：3 times refraction results showed that there was no significant difference between groups（all P〉0.05） . Conclusion：The concave lens or progressive multifocal lens could not slow down the development of myopia in children and adolescents.
