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.
