title: Very Late-Onset Corneal Scarring After Photorefractive Keratectomy Induced by Cataract Surgery.
abstract: OBJECTIVE
  To report two cases with very late-onset scarring of the cornea after photorefractive keratectomy (PRK) induced by cataract surgery.
  
  
  METHODS
  Case report and literature review.
  
  
  RESULTS
  Two patients presented with a subepithelial corneal scar more than 20 years after PRK. Scarring occurred within the first few months after cataract surgery. Scar tissue was successfully removed by laser-assisted anterior lamellar keratoplasty.
  
  
  CONCLUSIONS
  A few cases of late-onset corneal scarring after PRK have been described in the literature following trauma or ophthalmic surgery. Due to the need for cataract surgery in an aging population with previous PRK, this might become a more common problem.
