  5. Spherical or cylindrical error has progressed at -0.50D or less per year from date of baseline measurement.
  6. Contact lens wearers must have removed contact lenses at least two (2) weeks before the baseline measurement.
  7. No evidence of irregular astigmatism on corneal topography.
  8. Available to attend post-operative examinations for a 3 month period.

  4. Previous corneal surgery or trauma within the corneal flap zone.
  5. Patent corneal vascularization within 1mm of the corneal flap zone.
  6. Taking systemic medications likely to affect wound healing, such as corticosteroids and antimetabolites.
