title: Acanthamoeba keratitis during orthokeratology.
abstract: OBJECTIVE
  To report an infectious complication of overnight rigid gas-permeable contact lenses.
  
  
  METHODS
  Case report and medical literature review.
  
  
  RESULTS
  A 16-year-old girl developed laboratory-confirmed acanthamoebic keratitis during orthokeratology for myopic reduction. Recent case reports suggest that Acanthamoeba is a cause of microbial keratitis associated with gas-permeable contact lenses among teenagers and young adults undergoing orthokeratology.
  
  
  CONCLUSIONS
  Acanthamoeba keratitis is an emerging complication of orthokeratology in young myopes.
