title: Phototherapeutic keratectomy in recurrent corneal epithelial erosion.
abstract: BACKGROUND
  Excimer laser phototherapeutic keratectomy has generated considerable interest in treating superficial corneal and scleral pathology. The excimer laser is also used to treat recurrent corneal epithelial erosions.
  
  
  METHODS
  With the MEL 50 Aesculap-Meditec 193-nanometer argon-fluoride excimer laser, we treated 74 eyes of 73 individuals, who suffered from posttraumatic, therapy-resistant, recurrent corneal epithelial erosions. We used the excimer laser in spot-mode under manual guidance. Only in those eyes where the erosion was covered with loose bullous epithelium did we remove the epithelium mechanically prior to surgery. The postoperative follow-up period ranged from 6 months to 4 years.
  
  
  RESULTS
  Of the 74 eyes, 55 (74.43%) eyes were recurrence-free. One eye developed superficial haze in the treated area. No other complications occurred.
  
  
  CONCLUSIONS
  Phototherapeutic keratectomy in recurrent epithelial erosions is a promising treatment, especially in recalcitrant cases with the erosion over the entrance pupil. Photoablation allows a fast reepithelialization of the affected area and quick relief for painful symptoms.
