title: Paragon corneal refractive therapy lens prescribed for daily wear in a post-radial keratometry patient.
abstract: OBJECTIVE
  To present a case in which the Corneal Refractive Therapy (CRT) lens, a reverse-geometry contact lens designed specifically for overnight orthokeratology, was prescribed for daily wear in the treatment of a patient after radial keratotomy.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  The CRT lens provided adequate visual acuity and satisfactory daily wearing time without an adverse physiologic response.
  
  
  CONCLUSIONS
  This case illustrates an off-label use of the CRT lens to facilitate lens centration and provide a functional vision correction that enhanced a patient's ability to participate in activities of daily living. Although further study regarding the long-term safety and efficacy of this lens modality is needed, the findings suggest that these lenses provide a viable vision correction for patients who are dissatisfied with their postsurgical vision, particularly when satisfactory visual acuity cannot be achieved through conventional means.
