      Paragon CRT® and Dual Axis®

      Paragon helped set the Ortho-K industry standard with its pioneering Paragon CRT® lens. Paragon is the only company in the specialty lens industry to manufacture its own lens designs (Paragon CRT® and Dual Axis®) and lens material (HDS 100®). Both lens designs and material are FDA approved for overnight wear with no age restrictions.1 Lenses can be customized on a variety of parameters including lens power, diameter, base curve, lens tint, and center thickness.

      When it comes to myopia correction, Paragon CRT® has the highest rating in the industry, up to -6.00D sphere with or without up to -1.75 cyl.1 While Paragon CRT® is the proven lens for patients with spherical cornea, their innovative Paragon CRT Dual Axis® lens was designed specifically for patients with corneal astigmatism. The lens is noted for its centration, onset, efficacy, and long-term treatment consistency.

      Paragon CRT® is the lens that sets the standard for contemporary Ortho-K.

      Paragon’s lenses are trusted by patients in over 50 countries. When asked about their experience, CRT wearers report that their expectations were met or exceeded 97.6% of the time.2 n addition to outstanding lens designs, certified practitioners are supported throughout their journey to success with best-in-class Practice Management, Consultation and Marketing resources.
