    Journal: Cornea; 2022 May 01; 41(5):604-608. PubMed ID: 35383617.
    Abstract:
    PURPOSE: The purpose of this article was to evaluate the prognosis of traumatic flap dislocation or avulsion in a large series of laser-assisted in situ keratomileusis (LASIK) cases. METHODS: Retrospective, consecutive, noncomparative case series analyzes the visual and anatomical results after flap dislocation or avulsion, caused by trauma occurred at least 1 month after LASIK. RESULTS: A total of 37,315 eyes of 19,602 patients were reviewed. A traumatic flap complication was observed in 9 eyes of 9 patients, with a maximum interval of 37 months after surgery. Flap dislocation with central full-thickness folds was found in 5 cases; flap lifting and repositioning achieved a full recovery of uncorrected visual acuity. In another case, a partially detached flap was repositioned by a microsponge without lifting; self-limiting localized epithelial ingrowth followed. In 3 eyes, a complete flap avulsion occurred and, after epithelialization, a moderate refractive change was observed, comprised between -0.25 and -1 diopters (D) of spherical equivalent, with astigmatism <1 D; in 1 eye, the resulting myopia was corrected by repeat femtosecond LASIK. CONCLUSIONS: Traumatic flap complications after femtosecond LASIK are rare but can occur even in the long term; they have a favorable anatomic and visual prognosis.
