Device description
"Paragon Z CRT contact lenses are manufactured from Menicon Z® (tisilfocon A). The lenses are designed to have congruent anterior and posterior surfaces each consisting of three zones: The central spherical zone, a mathematically designed sigmoidal corneal proximity “Return Zone"" and a non-curving “Landing Zone”.The lens design also includes a convex elliptical edge terminus smoothly joining the anterior and posterior surfaces.Paragon Z CRT Contact Lenses for Corneal Refractive Therapy are to be worn overnight with removal during all or part of each following day. The lens material (tisilfocon A) is a thermoset copolymer derived from fluoro-methacrylate and siloxanylstyrene bound by crosslinking agents. The lenses for Corneal Refractive Therapy are available as lathe cut firm contact lenses with a light blue tint. The blue tinted lens contains D&C Green No. 6. A UV absorber (Benzotriazol) is added as an additive during the manufacturing process."

Orthokeratology contact lensA rigid-gas-permeable ophthalmic lens intended to be worn directly against the cornea of the eye for orthokeratology (Ortho-K), a procedure where the lens is worn for several hours, typically each night, to modify the curvature of the cornea as an alternative method to correct refractive vision conditions. The device is made of various materials (e.g., cellulose acetate butyrate, polyacrylate-silicone, silicone elastomers) whose main polymer molecules generally do not absorb or attract water but permit diffusion of oxygen (O2) to the ocular surface. This is a reusable device.
