NCT00366743

Brief Summary

The aim of the study was to evaluate visual outcomes, contrast sensitivity, glare testing and high order aberrations induced by different laser technologies and to evaluate differences in aberrometer technology. We hypothesized that there will not be differences among conventional or wavefront guided treatments.

  • irregular astigmatism
  • asymmetric astigmatism
  • unstable refraction
  • other criteria that preclude the patient to undergo LASIK
