摘　　要：[目的]探讨近视眼戴框架眼镜和角膜接触镜矫正的双眼视功能及其区别。[方法]选取近视眼63例,按习惯矫正方式分为框架眼镜矫正和角膜接触镜矫正两组,Von Graefe法测量每位近视的远、近距离水平隐斜,梯度性AC/A比率,远、近距离正、负融像性聚散,比较两组各参数差异。[结果]戴框架眼镜和角膜接触镜两组的近距离水平隐斜分别为(-7.33±3.67)△、(-4.12±3.35)△,AC/A比率分别为(2.69±1.78)△/D、(4.34±1.68)△/D,两组差异均有显著性意义(P<0.05),戴角膜接触镜近距离水平隐斜、AC/A比率更接近正常水平。戴角膜接触镜近距离负融像性聚散(21.32±5.12)△较戴框架眼镜组(17.14±6.03)△增大,两组差异有显著性意义(P<0.05);远距离水平隐斜,远距离正、负融像性聚散、近距离正融像性聚散两组比较差异无显著性意义(P>0.05)。[结论]近视戴角膜接触镜矫正,近距离水平隐斜、AC/A比率较戴框架眼镜更接近正常值。[Objective] To study the binocular function of myope with spectacle and soft contact lens and the difference between them.[Methods] Sixty-three myopes were selected in the study and divided into two groups according to the conventional correction way.Distance and near horizontal phoria,AC/A ratio,distance and near fusional vergence were measured in all subjects.[Results] Near horizontal phoria and near negative fusional vergence were（-7.33±3.67）^△,（17.14±6.03）^△ wearing spectacle.Those were（-4.12±3.35）^△,（21.32±5.12）^△ with soft contact lens,respectively.AC/A ratio were（2.69±1.78）^△/D,（4.34±1.68）^ △/D in the two groups.Statistically significant differences were found with soft contact lens correction in comparison to spectacle in near horizontal phoria,AC/A ratio and near negative fusional vergence（P〈0.05）.There was no difference in distance horizontal phoria,distance and near positive fusional vergence and distance negative fusional vergence（P〉0.05）.[Conclusion] Soft contact lens correction in myope reduces near exophoria,increases AC/A ratio and makes them close to normal values compared with spectacle correction.
