Intended Use

Prosthetic (polymacon) Hydrophilic Contact Lens (clear and tinted) is indicated for daily wear to enhance or alter the apparent color of the eye, including ocular masking, either in sighted or non-sighted eyes that require a prosthetic contact lens for management of conditions such as corneal, iris or lens abnormalities. The lens may also be prescribed for the correction of refractive ametropia (myopia and hyperopia) in aphakic and not-aphakic persons that may exhibit astigmatism up to 2.00 Diopters that does not interfere with visual acuity or for occlusive therapy for conditions such as diplopia, amblyopia or extreme photophobia. Eyecare practitioners may prescribe the lens for daily wear in a Frequent Replacement Program. The lenses may be disinfected using heat, chemical or hydrogen peroxide disinfection systems.

Device Story

Hemispherical soft contact lens; manufactured from polymacon (HEMA crosslinked with EGDMA); features colored pigments (e.g., carbazole violet, iron oxides, titanium dioxide) applied to the front surface iris area. Designed to fit over the cornea; provides corrective refraction for myopia, hyperopia, and astigmatism; masks ocular abnormalities. Prescribed by eyecare practitioners for daily wear; supports frequent replacement programs. Disinfection via heat, chemical, or hydrogen peroxide systems. Benefits include visual correction, ocular masking for cosmetic/prosthetic management, and occlusive therapy for specific eye conditions.

Clinical Evidence

Bench testing only. Toxicology testing (cytotoxicity, acute systemic toxicity, acute ocular irritation) demonstrated the lens is non-toxic. Residual monomer and color leachability testing confirmed no leachable color or significant residual monomers.

Technological Characteristics

Material: Polymacon (HEMA crosslinked with EGDMA); Group 1 non-ionic, low water content polymer. Dimensions: 14.5 mm diameter, 8.7 mm base curve, 0.08 mm center thickness. Power range: +8.00 to -8.00D. Pigments: Carbazole violet, chromium oxide green, dihydrodinaphto brown, dihydrodioxo yellow, phthalocyanine green, iron oxide red, iron oxide black, phthalocyanine blue, titanium dioxide. Manufacturing: Dry cast molded.

Indications for Use

Indicated for daily wear in sighted or non-sighted patients requiring prosthetic contact lenses for corneal, iris, or lens abnormalities; correction of refractive ametropia (myopia/hyperopia) in aphakic/non-aphakic persons with astigmatism up to 2.00D; or occlusive therapy for diplopia, amblyopia, or extreme photophobia.

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.

DATE SUMMARY PREPARED: November 20, 1998

TRADE NAME: Prosthetic (polymacon) Hydrophilic Contact Lens for Dally Wear (clear and tinted)

COMMON NAME: contact lens

SUBSTANTIALLY EQUIVALENT TO:

Prosthetic (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) are equivalent to Aspect Vision Care, Ltd.'s FREQUENCY 38 (polymacon) Hydrophilic Confact Lens for Daily Wear (clear and tinted) currently marketed in the U.S.

Prosthetic (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) are substantially equivalent to the indications for use of Aspect Vision Care, Ltd.'s FREQUENCY 38 (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) pursuant to K971049. The only addition to these indications are that the subject lens is also indicated to enhance or alter the apparent color of the eye, including ocular masking, either in sighted or non-sighted eyes that require a prosthetic contact lens for management of conditions such as corneal, iris or lens abnormalities. In addition, Aspect Vision Care. Ltd. will produce the dry cast molded lenses at the same manufacturing location as the predicate devices. These lenses are subsequently processed by CL-TINTERS to incorporate the pigments (i.e., listed color additives) to produce their unique tinting patterns.

This lens is in Group 1, non-ionic, low water content polymers as established by the FDA and located in the Guidance Document for Daily Wear Contact Lenses, Revised Edition May 1994. The physical, optical, and chemical properties of the Prosthetic (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) are equivalent to those of the

Aspect Vision Care, Ltd. FREQUENCY 38 (polymacon) Soft Contact Lens for Daily Wear (clear and tinted).

## DESCRIPTION of the DEVICE:

Soft contact lenses are hemispherical shells manufactured of polymerized material of HEMA crosslinked with EGDMA which yield the appearence of lanses which are designed to fit over the corneal surface of the lenses are made by modifying the uncolored polymacon cast molded lens by affixing a colored pigment on that portion of the front surface that corresponds to the iris. The colored pigments consist of: carbazole violet, chromium oxide green, dihydrodinaphto brown, dihydrodioxo yellow, phthalocyanine green, iron oxide red, iron oxide black, phthalocyanine blue and titanium dioxide. These lenses are designed with varying base curves which conform to the shape of the radius of the cornea and center over the apex of the cornea to provide corrective refraction for functional conditions of the eye including myopla (nearsightedness), hyperopia (farsightedness) and astigmatism (multiple foci). Each lens provides corrective power that is to correspond to the refractive power of the eye to which it is being treated. 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 which is generally of a diameter greater than 6mm. Secondary and tertiary curves as well as beveled edge configurations are built into the lens for the purpose of aiding in lens centration and comfort.

#### INDICATIONS FOR USE:

# Device Name: Prosthetic (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted)

Prosthetic (polymacon) Hydrophilic Contact Lens (clear and tinted) is indicated for daily wear to enhance or alter the apparent color of the eye, including ocular masking, either in sighted or non-sighted eyes that require a prosthetic contact lens for management of conditions such as corneal, ins or lens abnormalities. The lens may also be prescribed for the correction of refractive ametropia (myopia and hyperopia) in aphakic and notaphakic persons that may exhibit astigmatism up to 2.00 Diopters that does not interfere with visual acuity or for occlusive therapy for conditions such as diplopia, ambiyopia or extreme photophobia.

Eyecare practitioners may prescribe the lens for daily wear in a Frequent Replacement Program. The lenses may be disinfected using heat, chemical or hydrogen peroxide disinfection systems.

# Performance Testing of Contact Lens

Lenses were loaded with the following eleven pigments (i.e., listed color additives):

Carbazole violet, chromium oxide green, dihydrodinaphto brown, dihydrodioxo yellow, phthalocyanine green, iron oxide red, iron oxide black, phthalocyanine blue and titanium dioxide.

{2}------------------------------------------------

The results of toxicology testing (cytotoxicity, acute systemic toxicity and acute ocular irritation) have demonstrated that the subject lens is non toxic. Furthermore, the results of residual monomer and color leachability testing demonstrate that the respective extracts did not contain leachable color or significant levels of residual monomers.

The physical optical, and chemical properties of the Prosthetic (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) are equivalent to those of the FREQUENCY 38 (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) from Aspect Vision Care, Ltd. since this lens is provided to CL-TINTERS by Aspect Vision Care, Ltd.
