title: Keratectasia After Presbyopia Treatment With INTRACOR.
abstract: OBJECTIVE
  To report a case of keratectasis of a patient underwent INTRACOR presbyopic treatment 5 years ago.
  
  
  METHODS
  Case Report.
  
  
  RESULTS
  Fifty-eight-year-old gentleman had presented with deteriorating vision in his left eye. He reported undergoing INTRACOR presbyopic treatment in that eye 5 years ago. At presentation, his best-corrected visual acuity was 20/40. Slit-lamp examination of the left eye showed an ectatic cornea with concentric corneal scars. Corneal topography revealed marked keratectasia, with significant anterior and posterior elevations. The area of maximal corneal thinning coincided with the site of maximal elevation. Patient was fitted with hybrid contact lenses as a temporary treatment option and his best-corrected visual acuity improved to 20/30.
  
  
  CONCLUSIONS
  INTRACOR is one of the newer modalilities to correct presbyopia. One must be aware of the complication such as corneal ectasia after this presbyopic treatment.
