title: Corneal scarring and irregular astigmatism following refractive surgery in a corneal transplant.
abstract: BACKGROUND
  Scarring may follow refractive surgery, causing irregular astigmatism and loss of visual acuity.
  
  
  METHODS
  A case report of scarring and irregular astigmatism occurring in a corneal transplant following photorefractive keratectomy and arcuate incisions is presented.
  
  
  RESULTS
  Following surgical excision of the scar, unaided visual acuity improved from 1/60 to 6/12. Histopathology of the excised scar was obtained.
  
  
  CONCLUSIONS
  Refractive surgery following corneal transplantation may produce scarring. The origin of the scar in the present case has not been established.
