Late partial dislocation of a laser in situ keratomileusis flap

We report an apparently atraumatic asymptomatic flap dislocation 4 months after uneventful laser in situ keratomileusis (LASIK) in the right eye of a 43-year-old woman. The patient developed partial dislocation of the LASIK flap during the week after the 4 month examination. The LASIK flap was subsequently lifted to perform an enhancement, and the postenhancement course has been unremarkable. This case illustrates the potential susceptibility of LASIK flaps to dislocation either spontaneously or, more likely, after presumed minor trauma as late as 4 months after the original procedure.
