title: Bilateral Ectasia After Femtosecond Laser-Assisted Small Incision Lenticule Extraction (SMILE).
abstract: OBJECTIVE
  To describe a case of bilateral ectasia after small incision lenticule extraction (SMILE) in a patient with early keratoconus.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Bilateral SMILE was performed on a patient even though preoperative topographies showed changes indicating early keratoconus. The right eye underwent further photorefractive keratectomy enhancement 18 months later. The patient developed a bilateral corneal ectasia.
  
  
  CONCLUSIONS
  This case underlines the importance of thorough preoperative assessment for possible keratoconus suspect changes with corneal topography to avoid postoperative ectasia. [J Refract Surg. 2016;32(7):497-500.].
