目的 探讨影响近视眼远距离立体视觉恢复的因素, 从视觉最高级形式的角度评价准分子激光原位角膜磨镶术(LASIK) 的疗效.方法 采用英国产同视机联合颜少明新型同视机随机点立体图片对108 例近视患者( 其中近视性屈光参差62 例) 的术前及术后远距离立体视觉进行测定.结果 46 例单纯近视患者术后全部恢复中心立体视.62 例近视性屈光参差患者术后获中心立体视者40 例(64.5 ％ ) , 屈光度差与立体视锐度值呈正相关关系(R ＝ 0.67548 , P＜ 0.001) , 10 岁以后发病者立体视功能恢复较10 岁以前发病者佳( P＜ 0.05) .结论 LASIK 能有效地矫治近视和近视性屈光参差,对青少年单侧高度近视性屈光参差患者, 建议适当放宽LASIK 的手术年龄.“,”Objective To investigate the factors that affect the restoration of distant stereopsis after laser in situ keratomileusis (LASIK) for myopia and to evaluate the effect of this refractive surgery in terms of the highest class of vison. Methods The distant stereopsis was tested in 108 myopic patients pre and postoperatively with the synoptophore combined with the Yan's random dot stereogram. Results After operation, normal central stereopsis was restored in all of the 46 patients with simple myopia. Of the 62 myopic anisometropic patients, however, 40(64 5%) had normal postoperative central stereopsis. The stereoacuity was positively correlated with the amount of anisometropia (r=0 67548, P<0 001). The patients with the onset of anisometropia later than 10 years of age showed better recovery of stereopsis than those earlier than 10 years. Conclusion LASIK may effectively correct anisometropia. We suggest to lower a little bit of the age limit of excimer laser in situ keratomileusis for the young patients with high myopic anisometropia.
