title: Nocardial keratitis after laser in situ keratomileusis.
abstract: OBJECTIVE
  Corneal interface central nodules appeared in a patient who underwent uncomplicated laser in situ keratomileusis (LASIK) retreatment for residual myopia.
  
  
  CONCLUSIONS
  Nocardia asteroides keratitis was confirmed by microbiologic studies, which guided treatment. Six months after the appearance of the keratitis, the patient's uncorrected visual acuity was 20/45, and spectacle-corrected visual acuity was 20/40. The postoperative refraction was +0.75 -0.75 X 95 degrees, and slit-lamp examination revealed a clear cornea with a mild rounded scar in the central area. Night halos and starbursts were the main complaints in this patient. The immediate management of lifting the corneal flap for stromal bed scraping, fast microbial identification, and proper treatment was the key for the results in this patient.
