Traumatic flap dislocation 4 years after LASIK due to air bag injury.

PURPOSE: To report a patient who developed corneal flap dislocation following air bag injury 48 months after LASIK.

METHODS

Evaluation by slit-lamp microscopy and fluorescein angiography.

RESULTS

A 29-year-old man was treated after air bag injury that occurred 48 months after LASIK. Examination revealed corneal flap dislocation, with severe folds and flap edema. Preoperative visual acuity was finger counting at 1 m. Visual acuity was 20/400 24 hours after repositioning the corneal flap. Retinal angiography revealed Berlin macular edema, which was injected with periocular steroids. Five days after injection, visual acuity remained 20/400, but improved to 20/40 1 month after injection.

CONCLUSIONS

Significant trauma can dislocate a corneal flap many months after surgery.
