PURPOSE: To report our experience in treating cases of flap dislocation caused by trauma after laser in situ keratomileusis (LASIK). PATIENTS AND METHODS: We did a retrospective review of the case records of 16,319 patients (31,655 eyes) who underwent LASIK in Minamiaoyama Eye Clinic. Ten eyes of 9 patients were treated for flap dislocation. Conditions of the trauma occurrence, main findings of the eyes, treatments and clinical results are described. RESULTS: Dislocation occurred during a period of 5 days to 4 years after LASIK. Accidents happened when working, when playing with children or pets, or when fighting. The main findings were folds or microstriae, diffuse lamellar keratitis (DLK), and epithelial ingrowth, including partial splitting of the flap (1 eye) and only a crack in the epithelium of the flap edge (1 eye). Seven flaps were lifted, irrigated and repositioned, and observed after fitting the patients with soft contact lenses. Three flaps were treated with eye drops of hyaluronic acid only, or with systemic steroids, topical steroids, and antibiotics. Uncorrected visual acuity recovered to more than 1.0 in 7 eyes, and best corrected visual acuity (BCVA) was more than 1.0 in all eyes. However, 3 eyes lost one line and 1 eye lost two lines of BCVA. CONCLUSION: Many cases of flap dislocation showed recovery of good visual acuity with adequate and prompt treatment. However, it is possible to leave irregular astigmatism untreated which has a bad effect on visual acuity, depending on the affected part and the seriousness of the injury. The connection between patient and clinic is important for proper and prompt treatment.
