title: [Photorefractive keratectomy for treatment of ametropia after vitrectomy for retinal reattachment].
abstract: OBJECTIVE
  To evaluate the efficacy of photorefractive keratectomy (PRK) for the treatment of ametropia after vitrectomy for retinal reattachment.
  
  
  METHODS
  PRK was used to treat 11 eyes of ametropia after victrectomy for more than seven months. The visual acuity, retina and corneal endothelial cell densities were investigated in a l2-month follow-up study.
  
  
  RESULTS
  The postoperative visual acuity of all the 11 eyes was equal to or above the best corrected visual acuity before the operation. Postoperatively, there was no significant change of the corneal endothelial cell densities compared with that before the operation.
  
  
  CONCLUSIONS
  PRK for ametropia after vitrectomy is an effective and safe surgery. But the indication must be selected appropriately.
