title: [Comparison of PKR and LASIK for the treatment of low myopia: statistic study of refractive and optic results].
abstract: METHODS
  We present a study which compares the refractive and optical results obtained after PKR and LASIK for the correction of low myopia without astigmatism. This retrospective study involved 729 patients. All operations performed by the same surgeon, and with the same excimer laser (a Technolas Keracor 117 C). Before operation, all patients had a spherical equivalent between -0.5 and -6.0 D and a cylinder less than -0.5 D. Two groups were formed according to the treatment used. Three postoperative examinations were done (the first between 3 and 7 days, the second between 1 and 3 months, and the third between 10 and 14 months). Refractive results: Our statisticaly study found no difference in the results obtained with the two techniques.
  
  
  RESULTS
  The incidence of complications was similar for the two procedures, but those observed after LASIK are generally more serious.
  
  
  CONCLUSIONS
  In this indication, the efficacy of PKR and LASIK is similar.
  
  
  CONCLUSIONS
  PKR and LASIK are safe and efficacy for the treatment of low myopia. For these patients, the use of PKR of LASIK currently depends on the habit and preference of the surgeon.
