Paragon corneal refractive therapy lens prescribed for daily wear in a post-radial keratometry patient.

摘要

PURPOSE: 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.
