Cogan syndrome presenting after uneventful laser in situ keratomileusis.

We report 2 cases of Cogan syndrome that developed after uneventful laser in situ keratomileusis. In the first case, an 8-month postoperative biomicroscopy revealed bilateral interface neovascularization, white intrastromal deposits, and anterior chamber cells and flare. In the second case, white cell infiltration and neovascularization were observed in the deep corneal stroma of the patient's right eye 18 months postoperatively. Based on these observations, which are consistent with typical interstitial keratitis, and the patients' history of Meniere-like disease, such as vertigo and mild hearing loss, Cogan syndrome was diagnosed in both patients. Topical steroids were prescribed. Intensive treatments with corneal irrigation and topical steroids showed effective outcomes in both cases.
