Device Description

Paragon CRT® Contact Lenses are manufactured from Paragon HDS® (paflufocon B). 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”. Paragon CRT® Contact Lenses for Corneal Refractive Therapy are to be worn overnight with removal during all or part of each following day. The material is thermoset fluorosilicone acrylate copolymer derived primarily from siloxane acrylate, trifluoroethyl methacrylate and methylmethacrylate with a water content of less than 1%. These contact lenses for Corneal Refractive Therapy are available as lathe cut firm contact lenses with blue, violet and green tints. The tinted lenses depending on the tint color contain D&C Green No. 6, D&C Violet No. 2 and Perox Yellow No. 9 (4-[(2,4-dimethylphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-one). These products may be plasma treated.

47926	Orthokeratology contact lens	A 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.	No	Active
