Myopia Profile

Paragon CRT®

Paragon CRT® contact lenses are orthokeratology contact lenses that have been used by eye care professionals for myopia management for two decades, following the first FDA approval for overnight wear contact lenses indicated for the temporary reduction of myopia. The Paragon CRT ortho-k lenses can be fit empirically, with a diagnostic set or through topography-guided fitting.  The robust evidence base for orthokeratology means it can be considered a first-line treatment for children with myopia.
