目的：探讨准分子激光角膜原位磨镶术(laser
in situ keratomileusis， LASIK)和准分子激光角膜前弹力层下磨镶术(Sub-Bowman's keratomileusis，SBK)术后外伤性角膜瓣移位的处理。
方法：对14例14眼LASIK和SBK术后因外伤导致角膜瓣移位的患者，经及时手术处理，合理用药，视力恢复良好。
结果：选取的14例中13例治疗术后1wk视力均达到0.8以上，角膜透明，无1例患者角膜出现角膜瓣皱褶、上皮植入、角膜瓣溶解。1例患者因角膜瓣全部移位，治疗术后1wk视力0.1，角膜全层水肿，角膜瓣下皱褶不明显，下方瓣缘裂伤处有1～2mm宽的上皮植入。术后6mo，视力达到1.0，角膜完全透明。
结论：及时正确处理LASIK和SBK术后外伤性角膜瓣移位均能获得良好视力。

AIM: To explore the treatment of traumatic corneal flap displacement after laser
in situ keratomileusis( LASIK)and Sub-Bowman keratomileusis(SBK)treatment.
METHODS:Totally 14 cases 14 eyes, after LASIK and SBK operation, resulted in corneal flap displacement due to trauma, and after timely treatment, operation, rational drug use, they achieved good recovery of vision.
RESULTS:Among the 14 cases, after 1 week, 13 cases achieved visual acuity of 0.8 above, and their cornea were transparent. None of the patients had corneal flap folds, epithelial implantation, corneal flap melt. 1 patient with corneal flap displacement and visual acuity of 0.1 after 1 week, visual acuity, corneal edema, corneal flap folds beneath the flap edge was not obvious, laceration of a branch of 1-2mm wide epithelial implantation. 6 months postoperatively, visual acuity reached 1, full transparent cornea.
CONCLUSION:Timely and correct treatment of traumatic corneal flap displacement after LASIK and SBK can obtain good vision.
