- Generic Name
- Orthokeratology contact lens FDA UDI
- Device Name
- Paragon RG-4 contact lenses are manufactured from Paragon HDS® 100. The reverse geometry design has a posterior surface consisting of four zones: The central spherical or aspheric zone, an annular “Reverse Zone(s)”surrounding the central zone with a curvature steeper (shorter radius) than the central zone, an “Alignment Zone(s)” generally paralleling the underlying corneal surface and peripheral curve(s) with a radius selected to create “edge lift” to promote tear flow under the lens and avoid impingement of the peripheral curve on the cornea. The lens design also includes a “rounded” edge terminus extending from the anterior to the posterior surfaces to promote comfort. Paragon RG-4 Contact Lenses for Corneal Reshaping are to be worn overnight with removal during all or part of each following day. The material is a 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 reshaping are available as lathe cut firm contact lenses with blue, green, red and yellow tints containing D&C Green No. 6, D&C Red No. 17 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. FDA UDI
