摘　　要：目的:探讨准分子激光原位角膜磨镶术(LASIK)对近视眼患者双眼影像不等(B A)的影响。方法:采用中国人民解放军海军总医院眼科刘蔼年设计的《双眼影像不等检查图》,对64例行LASIK术的近视眼患者按双眼屈光度差的程度分为四组,术前、术后6个月分别行BA检查,并观察双眼视力与BA恢复的关系。结果:双眼屈光度差≤2.50D的患者术前、术后双眼影像不等的一、二、三类检查图的差异无显著性。屈光度差大于2.50D的患者,术前、术后双眼一、三类检查图的差异有显著性,术后双眼裸眼视力与第三类检查图的恢复密切相关。结论:LASIK术可以使双眼屈光度差值大的患者的BA减小到可以承受的范围,并有助于三级功能的恢复,同时术后视力越好,三级功能恢复越佳。眼科学报2003;19:107-109。Purpose:To explore the effect produced by laser in situ keratomileusis (LASIK)on binocular aniseikonia(BA) and steropsis of myopic patients. Methods: Sixty-four cases who received LASIK were divided into 4 groups by different binocular diopter with the binocular aniserkonia (BA) designed by Liugeping and BA. The patients were tested on 6 months before and after the operation respectively for studing the relationship between the post-operative BA and steropsis. Results:When the binocular diopter difference was ≤2.5D,there was no significant difference between the preoperative and postoperative BA.When the diopter difference was>2.50D, the incongruons images of simultaneous perception and stereoscopic vision after operation had significant divergence compared with those before the operation.The postoperative stereopsis was closely related to binocular vision. Conclusion: LASIK can not only reduce the BA of high myopic anisome tropia patients to a range that can be endured, but also be helpful to restore the stereopsis. Moreover,the better the postoperative binocular vision,the patients have the finer the stereopsis will be. Eye Science 2003 ;19:107-109.
