title: Interface corneal stromal irregularities after flap creation using femtosecond laser.
abstract: OBJECTIVE
  To report a case of interface corneal stromal irregularities after flap creation with the advanced IntraLase femtosecond (150 Hz) laser system (Abbott Medical Optics, Inc.).
  
  
  METHODS
  Case report.
  
  
  RESULTS
  An 18-year-old man underwent bilateral laser in situ keratomileusis (LASIK) using the IntraLase femtosecond laser to create 110-µm flaps. The procedure was uneventful in the left eye. In the right eye, after flap lifting a central irregular stromal interface was noted. The created flap was thicker than expected (139 µm) as measured intraoperatively with ultrasound pachymetry. The excimer laser ablation procedure was performed and the flap was repositioned. On the first postoperative day and during the 6-month follow-up period, uncorrected distance visual acuity was 20/20 in both eyes.
  
  
  CONCLUSIONS
  Interface corneal stromal irregularities may occur after femtosecond corneal flap creation during LASIK.
