To explore the effect produced by laser in situ keratomileusis (LASIK) on binocular aniseikonia(BA) and steropsis of myopic patients.


Sixty-four cases who received LASIK were divided into 4 groups by different binoeular 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.


When the binocular diopter difference was < or = 2.5 D, there was no significant difference between the preoperative and postoperative BA. When the diopter difference was > 2.50 D, 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.


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.
