isnt it just another name for Orthokeratology?
Paragons approval from the FDA for overnight corneal reshaping is for Corneal Refractive Therapy. Historically, Ortho-K involved using a series of lenses over a period of months to achieve the desired effect. Corneal Refractive Therapy with Paragon CRT is primarily a single lens therapy over a period of 5-14 days. Although corneal reshaping with contact lenses is not a new concept, previous corneal reshaping designs were only as successful as technology allowed. Paragon Vision Sciences has taken the recent advancements in computerized corneal mapping, computerized manufacturing and oxygen permeable contact lens materials and produced a therapeutic lens that is unique in its design and application. Paragon also undertook the most extensive overnight study ever attempted in this modality to demonstrate its safety and efficacy. As a result, Paragon CRT stands alone with supportive science and new technology.
