Maddox rod effect to confirm the visual significance of laser in situ keratomileusis flap striae.

UNLABELLED: Laser in situ keratomileusis (LASIK) flap striae can act as a Maddox rod, producing streaks of light perpendicular to the orientation of the striae. This phenomenon can be used in the diagnostic and surgical decision-making process after LASIK. We correlated persistent complaints of starburst by a patient to the presence of LASIK flap striae in both eyes. The more severe striae were subsequently treated with phototherapeutic keratectomy, with complete resolution of symptoms. The LASIK flap striae-induced Maddox rod effect can be used as a simple and useful method with high diagnostic and therapeutic value.
