Reactivation of presumed adenoviral keratitis after laser in situ keratomileusis.

We report a patient with reactivation of presumed adenoviral keratoconjunctivitis after laser in situ keratomileusis (LASIK) to correct high myopia. The preoperative refraction was -13.00 diopters (D) in the right eye and -14.00 D in the left eye, and the best corrected visual acuity was 20/20 in both eyes. On the first postoperative day, mild conjunctival hyperemia and multiple subepithelial infiltrations localized in the flap zone consistent with adenoviral keratoconjunctivitis were seen. After prompt treatment, the lesions resolved. As a consequence, LASIK successfully corrected the high myopia. Adenoviral keratoconjunctivitis can be reactivated after LASIK, unlike after photorefractive keratectomy, despite the absence of symptomatic and clinical findings before the procedure.
