title: Topical thiotepa treatment for recurrent corneal haze after photorefractive keratectomy.
abstract: OBJECTIVE
  To describe the use of topical thiotepa in the treatment of recurrent haze after photorefractive keratectomy (PRK).
  
  
  METHODS
  Gimbel Eye Centre, Calgary, Alberta, Canada.
  
  
  METHODS
  Five patients with recurrent haze after myopic PRK were retreated with phototherapeutic keratectomy and topical thiotepa. Before retreatment, the best corrected visual acuity (BCVA) ranged from 20/40 to 20/200. Follow-up ranged from 3 to to15 months.
  
  
  RESULTS
  Haze, uncorrected visual acuity (UCVA), and BCVA improved in all patients. Three eyes had a UCVA of 20/20(-2) or better and a BCVA of 20/20(-1) or better. The other 2 eyes experienced regression of the myopia and astigmatism and had a BCVA of 20/25(-1) or better.
  
  
  CONCLUSIONS
  Topical thiotepa appeared to be an effective treatment for recurrent corneal haze following myopic PRK.
