title: [Long-term clinical course of excimer laser photorefractive keratectomy].
abstract: OBJECTIVE
  Long-term clinical follow-up for 5 years or longer has not yet been reported in Japan. We performed excimer laser photorefractive keratectomy(PRK) on 181 eyes from 1990 to 1993, and 44 of those eyes could be followed for 8 to 10 years.
  
  
  METHODS
  The 44 eyes were divided into 3 groups depending on degree of correction. We compared of safety, efficacy, predictability-spherical equivalent, stability, complication, and satisfaction among the 3 groups.
  
  
  CONCLUSIONS
  The first generation PRK was certified clinically to be safe and stable in patients corrected for low to moderate myopia.
