These lenses are designed with varying base curves that conform to the shape of the radius of the cornea and center over the apex of the cornea to provide correction of refractive ametropia (myopia, hyperopic, astigmatism and presbyopia) in aphakic or not-aphakic persons with nondiseased eyes. Each lens is designed with a base curve on the internal side of the lens and an optical zone in the center of the lens, generally of a diameter greater than 6 mm. The primary and secondary curves as well as beveled edge configurations are built into the lens for the purpose of aiding on the lens centration and comfort. Adding color enhancement to the surface of the lens modifies the clear version of the Horizon 59 Oasis (hioxifilcon A) contact lens. The tinting process alters or changes the lens by affixing a listed color reactive additive on that portion of the anterior (front) surface of the lens that corresponds to the irris. The color additives are used in the amounts not to exceed the minimum reasonably required to accomplish the intended coloring effect. The practitioner may also choose tint intensity and custom mix colors. The Horizon 59 Oasis (hioxifilcon A) lenses are available in shades of the following: blue, green, brown and aqua. Combining one or more reactive colors additives with distilled water forms the color enhancement. The reactive color additives that may be used either alone or in combination are: Reactive Blue 19, Reactive Black 5, Reactive Red 11, Reactive Orange 78, Reactive Yellow 15, Reactive Red 180. #### Substantially Equivalent To: 5.0 Westcon will be claiming equivalency to our own that is currently FDA approved in 510(k) K031774. #### Summary of Safety and Effectiveness 6.0 The Horizon lenses were subjected to leachability studies and showed no identifiable evidence of tint pigment leaching. #### Technical Summaries 7.0 #### 7.1 Toxicology: Cytotoxicity, systemic toxicity and ocular irritation studies were. Test results showed no evidence of cellular or systemic toxicity, or ocular irritation. {2}------------------------------------------------ ## Summary of Safety and Effectiveness 8.0 - Physical/Optical Characteristics 7.2 Light transmittance, linear expansion and radial expansion were determined. A comparison of data from these studies showed that the Horizon 59 Oasis (hioxifilcon A) is equivalent in physical and optical characteristics as 510(k) K031774. - 7.3 Microbiology There will be no changes to the validated process in 510(k) K954524 - 7.4 Compatibility The spectra measurement after the numerous cleaning and disinfecting cycles remained the same as the before measurement. - The shelf life study has been started on color-enhanced lenses and will be 7.5 completed in 2005 year. The procedure is based on the guidance documents Shelf Life of Medical Devices-April 1991 and Premarket Notification Guidance Document for Daily Wear Contact Lenses-May 1994. The packaging remains the same as 510(k) K954524. #### Conclusion 8.0 In conclusion, it is Westcon's conviction that the data submitted shows the Horizon 59 Oasis (hioxifilcon A) contact lens does not raise different questions of safety and effectiveness. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
