Late traumatic flap displacement after laser in situ keratomileuisis.

Laser in situ keratomileusis (LASIK) has become the community standard in corneal refractive surgery and is being performed by surgeons in the Army, Navy, and Air Force. LASIK differs from photorefractive keratectomy (PRK) in that a partial-thickness corneal flap is created in the LASIK procedure before removing a microscopic amount of corneal tissue, whereas no flap creation is required in PRK. The benefits of LASIK include minimal discomfort after surgery, as well as a much faster return of visual function. PRK involves a surface ablation and therefore heals differently, involving more discomfort and a slower return of functional vision. LASIK flap integrity is a concern to anyone undergoing the procedure, as well as for those making recommendations on the best form of refractive surgery for military personnel. A case report and a review of the literature are presented on the identification and management of LASIK flap trauma.
