title: Recovery of refractive error after corneal refractive therapy.
abstract: OBJECTIVE
  To describe the regression of treatment (i.e., return toward baseline refractive error findings) after treatment with corneal refractive therapy (CRT).
  
  
  METHODS
  After 6 to 9 months of treatment by a standardized protocol for CRT (application of high-Dk, proximity control, return zone contact lenses for overnight reduction of myopia), refractive error was measured within hours after awaking and at 8, 24, 48, and 72 hours. Comparison of regression is analyzed in four categories of achieved treatment. Logarithm of the minimum angle of resolution visual acuity regression was also measured.
  
  
  RESULTS
  In general, refractive error returns to baseline after CRT for all measured ranges of refraction in the period of measurement of this study.
  
  
  CONCLUSIONS
  The greater the magnitude of CRT treatment, the more rapid the recovery is to baseline refraction.
