摘　　要：目的用多种方法测准分子激光原位角膜磨镶术，矫治近视性屈光参差患者术前及术后远、近立体视觉，从视觉最高级形式的角度评价LASIK矫正近视性屈光参差患者的临床应用价值。方法对112例近视性屈光参差患者，手术前和LASIK手术3个月后，采用颜氏随机点立体视觉检查图检查近立体视锐度、交叉视差、非交叉视差，Titmus立体视觉检查图、金贵昌双眼立体视觉检查图检查近立体视觉，同视机随机点立体图片检查远立体视觉。结果LASIK术后3个月，91．9％患者裸眼远视力达到或超过术前最佳矫正视力。3种方法检查术后远、近立体视锐度均明显增进。立体视觉的增进显著，有统计学意义（P〈0．05）。结论LASIK手术能重建、改善和促进立体视觉功能，有效地矫治屈光参差，手术安全、治疗效果肯定。Objective With several methods,pre- and post-operative far and near stereopsis were tested in patients with myopic anisometropia undergone laser in situ keratomileusis （LASIK）. So clinical effects of this treatment were evaluated at the highest level of vision function. Method 112 myopic anisometropia patients were enrolled in the research before the operation and 3 months after anisometropia were abolished by LASIK. Near stereopsis, crossed disparity and uncrossed disparity were measured by Yan＇s random-dot stereograms. Near stereopsis was also measured by Titmus stereograms and Jinguichang random-dot stereograms. Far stereopsis was measured by synoptophore. Results 3 months after LASIK, UCVAs of 91.9% patients were the same as or better than those of preoperative. Far and near stereopsis were improved obviously measured by all three methods. There is significant difference in the improvement of stereopsis. Conclusion With the treatment of myopic anisometropia by LASIK,most patients got much improvement in far and near stereopsis. LASIK could rebuild, improve and promote the stereopsis, and treat the anisometropia effectively and safely.
