基层眼科老视三种验配方法比较

目的探讨基层眼科老视的科学验配方法。方法收集老视患者240例，年龄45-63岁，随机分为甲、乙、丙三组，每组80例。甲组给予传统经验法验配；乙组给予工作距离减去储备的调节幅度法验配；丙组由综合验光仪验配；对三组验配结果和舒适度进行统计学分析。结果甲、乙、丙三组的视力矫正差异无统计学意义（P〉0．05）；三者长期戴镜的舒适度比较显示：乙组、丙组均优于甲组（P〈0．05），乙组、丙组差异无统计学意义（P〉0．05）。结论乙、丙二组老视的科学验配优于甲组的经验验配，可以达到清晰、舒适、持久的视觉效果，在基层眼科中应广泛开展。

A comparative study of three methods for scientific fitting presbyopia in primary hospital

Objective To compare the effect of three methods for scientific fitting presbyopia in primary hospital. Methods 240 patients with presbyopia,whieh aged from 45 to 63,were randomly divided into three groups. Each group had 80 cases. Group A were treated by routine optometry, group B by distance minus the reserve job amplitude method and group C by optometry equipment. The fitting effect of three groups was compared. Results There was no significant difference on the effect of vision correction in three groups （P〉0. 05）. After long - term wear , the patients in group B and C felt more comfortable than that in group A（P〈0. 01）. Conclusion Distance minus the reserve job amplitude method and optometry equipment can get clear, comfortable, long- lasting vision effect and should be widely carried out in primary hospital.
