The color-enhanced version is indicated for daily wear to enhance or alter the apparent eye color. The color-enhanced lenses can be chemically disinfected only. The clear lenses may be disinfected using a heat or chemical disinfecting system.

Device Story

Soft contact lenses manufactured from methafilcon A or polymacon lens blanks; lathe-cut into hemispherical shells designed to fit corneal surface. Features include base curve, optical zone (>6mm), and beveled edges for centration and comfort. Color-enhanced versions utilize listed color-reactive additives (e.g., Reactive Blue 19, Reactive Black 5) affixed to the anterior surface corresponding to the iris. Used by eye care practitioners to correct refractive errors and enhance eye appearance. Lenses are worn daily; clear lenses disinfected via heat or chemical systems; color-enhanced lenses disinfected via chemical systems only. Benefits include refractive correction and cosmetic enhancement.

Clinical Evidence

Bench testing only. Toxicology studies (cytotoxicity, systemic toxicity, ocular irritation) performed with no evidence of toxicity or irritation. Leachability studies showed no pigment leaching. Spectra measurements confirmed compatibility after cleaning/disinfecting cycles.

Technological Characteristics

Materials: Methafilcon A and Polymacon. Form factor: Lathe-cut hemispherical soft hydrophilic contact lens. Tinting: Reactive color additives affixed to anterior surface. Disinfection: Chemical (all) or heat (clear lenses only).

Indications for Use

Indicated for daily wear correction of refractive ametropia (myopia, hyperopia, astigmatism, presbyopia) in aphakic or non-aphakic persons with nondiseased eyes. Color-enhanced versions indicated for daily wear to enhance or alter apparent eye color.

Regulatory Classification

Identification

A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.

# Summary of Safety and Effectiveness 8.0

### 4.0 Device Description

The soft contact lenses that are manufactured from W-55 and W-38 lens blanks are lathe cut into a hemispherical shell that are designed to fit over the corneal surface of the eye. 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 eves.

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 55 (methafilcon A) Contact Lens and Horizon 38 (polymacon) 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 iris. 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 Enhanced 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.

## 5.0 Substantially Equivalent To:

Westcon will be claiming equivalency to our own contact lenses that are currently FDA approved in 510(k) K992010 and 510(k) K963837.

## Summary of Safety and Effectiveness 6.0

The Horizon lenses were subjected to leachability studies and showed no identifiable evidence of tint pigment leaching.

# 7.0 Technical Summaries

- 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

#### 7.2 Physical/Optical Characteristics

The color-enhanced version remains the same as the clear version 510(k) K992010 and 510(k) K963837.

- 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 later this 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 and 510(k) K963837.

#### 8.0 Conclusion

In conclusion, it is Westcon's conviction that the data submitted shows that by adding the color-enhancement tint to the surface of the contact lens does not raise different questions of safety and effectiveness.
