目的　探讨轻度过矫对共转性内斜的远期疗效。方法　 6 3例共转性内斜采用内直肌边缘切开术 ,必要时加外直肌缩短术。其中 31例为常规治疗组 ,术终将眼位调整至正位 ;32例为轻度过矫组 ,术终将眼位调整至外斜 5°左右。术后随访 3月以上 ,观察眼位 ,并进行两组间差异的统计学处理。结果　术后 3月 ,常规治疗组矫正不足 12例占 39 0 3% ,轻度过矫组矫正不足 2例占 6 2 5 %。结论　共转性内斜手术中轻度过矫可避免术后远期矫正不足 Objective To investigate the long-term effect of mild overcorrection on co-translocation esotropia. Method 6 3 cases of co-transversal internal oblique incision with the edge of the rectus muscle, if necessary, plus lateral muscle shortening surgery. Among them, 31 cases were routine treatment group, and the eye position was adjusted to the positive position at the end of surgery. 32 cases were mild overcorrection group, and the eye position was adjusted to be about 5 ° outwardly. The patients were followed up for more than 3 months to observe the eye position and to carry out statistical analysis of the differences between the two groups. Results In March, there were 12 cases (39 0 3%) in the conventional treatment group and 6 2 5% (2 cases) in the mild overcorrection group. Conclusions The mild overcorrection in co-transversal esotropia can avoid the long-term postoperative correction
