摘　　要：目的研究框架眼镜MPMVA处方与矫正视力1.0处方对青少年近视增长的影响,探讨延缓青少年近视增长处方原则。方法横断面研究。选取2019年9月至12月在唐山市眼科医院视光学诊疗中心就诊的9~14岁近视儿童,完成眼前节、眼底、眼压、眼轴、眼位检查后,1%盐酸环喷托酯滴眼液睫状肌麻痹后电脑验光及视网膜检影验光,调节恢复后复验配镜,镜片均选择单焦点非球面镀膜树脂镜片。共纳入712例(1424眼)。随机分成两组,按各组处方标准定配框架镜。最佳矫正视力的最大正镜化(MPMVA)组351例(702眼);矫正视力1.0组361例(722眼)。记录每组儿童平均等效球镜度与眼轴,半年后复查散瞳验光,最大屈光力子午线方向屈光度变化≥-0.50D者需更换镜片。1年后再次散瞳验光,记录每组儿童平均等效球镜度与眼轴。应用配对t检验方法,P<0.05差异有统计学意义,对比分析平均等效球镜度与眼轴变化。结果 1年后对比分析2组患者平均等效球镜度(t=9.734,P<0.001)及眼轴长(t=6.597,P=0.002)增长量差异有统计学意义。MPMVA组平均等效球镜度与眼轴增长量低于矫正视力1.0组。结论 9~14岁近视儿童,定配框架眼镜处方应该首选MPMVA原则。Objective To study the effects of frame glasses MPMVA and that of CVA 1.0 prescription on controlling juvenile myopia,and probe into prescription principles to control juvenile myopia.Method Cross-sectional study.Myopic children at ages of 9 to 14 received by Optometry Diagnosis and Treatment Center,Tangshan Eye Hospital were selected as study subjects.After examinations on position of eye,axis oculi,anterior segment,eye ground,and intraocular pressure,1% cyclopentolate hydrochloride was dropped into eyes with mydriasis.After ciliaris was paralyzed,computer optometry and retinoscopy optometry were carried out.After adjustment and recovery,eyes with mydriasis were rechecked for prescribing spectacles.Spectacle lens prescribed were all monofocal aspherical coated resin lenses.There were 712 cases(1,424 eyes) involved in this experiment.These children were randomly divided into two groups and got frame glasses based on each group’ prescription standard.There were 351 cases(702 eyes) in the group of MPMVA for best corrected visual acuity,and 361 cases(722 eyes) in the group of CVA 1.0.The mean value of spherical equivalent and axis oculi of each group were recorded.Six months later,these children had mydriatic refraction,and those whose diopter change in the meridian direction of maximum refractive power was≥-0.50 D needed to change their ophthalmic lens.One year later,mydriatic refraction was conducted again and the change of mean value of spherical equivalent and axis oculi of each group were recorded again.Result After contrastive analysis one year later,it was found that the differences in these two groups’ worsening degree of spherical equivalent refraction(t=9.734,P<0.001) and increase in length of axis oculi(t=6.597,P=0.002) were of statistical significance.The average worsening degree of spherical equivalent refraction and increase in length of axis oculi of the MPMVA group were lower than that of the CVA 1.0 group.Conclusion The MPMVA principle shall be a priority in the prescription for frame glasses
