(Abstract Objective To study the effect of convex rism lens on prevention and control of myopic development in
teenagers. Methods One hundren cases of teenager myopia confirmed to be low myopia or normal vision, with normal
alignment of both eyes or horizontal heterophoria <8 A, were randomly divided into observation group and control
group, 50 cases in each group. The cases whose myopia diopter= -1.00 D wore nearwork glasses otherwise did not
The in even on met ods of observaion up as follow: The myopia teenagers were asked to wear the onvex prism lens
with +1.50 D -+2.00 D ase when they studied or ook a close look. No intervention was performed in the control group
The vision, diopter, optic axis, yes position and heero a were ested in both groups before intervention and one year
af er inervention respectivel Resul s mad with the controls, ioptor increased si nificantly by(0. 40.36) D
and optic axis increased significantly by(0. 12 *O. 30)mm in the observation group(P <0.05). There were 4 cases
(8.0% )of increased heterophoria in the observation group while 5 cases(10.0%)in the control group. No significant
difference was found in eyes position changes between the two groups(P >0.05). Conclusion Convex prism lens has
significant effect on prevention and control of myopic development in teenagers, but it may probably increase the
incidence of heterophoria. Further study is needed to observe the long-term effect of convex prism lens and its adverse
reaction of heterophoria

目前我国已是世界上青少年近视患病率较高的视患者配戴凸透三棱镜对预防及控制近视效果,现报
国家之一。调査显示,我国学生近视患病率逐年升告如下。
高,且发病年龄明显提早。笔者观察50例低度近
