Fourth-generation fluoroquinolones in the treatment of mycobacterial infectious keratitis after laser-assisted in situ keratomileusis surgery.

CASE REPORT: Infectious keratitis after laser-assisted in situ keratomileusis (LASIK) is a rare complication that may be challenging to diagnose and treat. We discuss some of the reasons for difficulties diagnosing postoperative atypical or nontuberculous mycobacterial infection and establishing an effective treatment, with reference to reports of comparative antibacterial activity of the most commonly used antibiotics. COMMENTS: To the best of our knowledge, we are the first to report the use of the fourth-generation fluoroquinolone moxifloxacin in combination therapy for the successful treatment of this condition.
