Abstract

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 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.

RESULTS:

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.

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.
