Intended Use

The CANTOR & SILVER 5X PROSTHETIC Tinted Soft Contact Lens are indicated for daily wear to enhance or alter the apparent eye color, including ocular masking, either in sighted eyes that require a prosthetic contact lens for cosmetic management of conditions such as corneal, iris or lens abnormalities. The lens may also be prescribed for the correction of refractive ametropia (myopia, hyperopia and astigmatism) in aphakic and not aphakic persons or for occlusive therapy for conditions such as diplopia, amblyopia or extreme photophobia. The lens are disinfected using a hydrogen peroxide lens care system only and are available in a frequent replacement program.

Device Story

Prosthetic tinted soft contact lens; hioxifilcon A material; anterior surface tinted with FDA-listed reactive color additives to mask ocular abnormalities or alter eye color. Available in patterns: clear lens with black pupil, black occluder, black annular with clear pupil, or tinted lens with black pupil. Prescribed by eyecare professionals for daily wear; requires hydrogen peroxide disinfection. Lens tinting process does not alter optical or performance characteristics. Benefits include cosmetic restoration of eye appearance and therapeutic occlusion for specific ocular conditions.

Clinical Evidence

No clinical data provided; substantial equivalence based on descriptive characteristics and comparison of materials and intended use to predicate devices.

Technological Characteristics

Material: hioxifilcon A (poly hydroxyethyl methacrylate). Tinting: reactive color additives (e.g., reactive blue 21, 19, 4, 163; red 11, 180; yellow 15, 86; orange 78) affixed to anterior surface. Form factor: soft contact lens, daily wear. Disinfection: hydrogen peroxide system only. Manufacturing: reactive additives washed to remove unbound material.

Indications for Use

Indicated for daily wear in sighted eyes for cosmetic management of corneal, iris, or lens abnormalities; correction of refractive ametropia (myopia, hyperopia, astigmatism) in aphakic/non-aphakic persons; 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.

#### Substantially Equivalent Devices:

The "CANTOR & SILVER 5X PROSTHETIC" Tinted Soft Contact Lens is substantially equivalent to the "Alden Classic Prosthetic Tinted Soft Contact Lens" and the Cantor & Silver "CANTOR & SILVER 5X Tinted", the predicate devices.

# Device Descriptive Characteristics:

The CANTOR & SILVER 5X PROSTHETIC Tinted Soft Contact Lens are tinted with FDA "listed" color additives. The color additives are used in amounts not to exceed the minimum reasonably required to accomplish the intended coloring effect. As part of the manufacturing process, the lens containing the color additives are thoroughly washed to remove unbound reactive color additives. The manufacturing process alters and/or changes the specifications to the clear version of a contact lens by affixing a listed reactive color additive on that portion of the anterior (front) surface of the lens that corresponds to the iris. The CANTOR & SILVER 5X PROSTHETIC Tinted Soft Contact Lens are tinted to the eyecare professional instructions.

The prosthetic color additive effect is formed by reacting one or more of the reactive color additives listed in this paragraph with (poly hydroxyethyl methacrylate). The reactive color additives that may be used either alone or in combination are: reactive blue 21, reactive blue 19, reactive blue 19, reactive blue 4. reactive blue 163, reactive red 11, reactive red 180, reactive yellow 15, reactive yellow 86, or reactive orange 78. The color additives used are not removed by lens handling or approved cleaning/disinfecting procedures. The prosthetic lens tinting process does not alter the optical and/or performance characteristics of the finished tinted soft contact lens.

Tint Patterns Available:

- 1. Clear lens with Black Pupil. Pupil sizes available in 2.0 mm to 12.5 mm.
- 2. Black Occluder Lens. A Central Black area that occludes light. Available to full lens diameter in 0.5 mm increments.
- 3. Black Annular with clear pupil. Black Annular diameter range 7.5 mm to full lens diameter in 0.5 mm increments. Clear Pupil diameter range 2.0 mm to 7.5 mm in 0.5 mm increments.
- 4. Tinted lens with Black Pupil. Uses the CANTOR & SILVER 5X PROSTHETIC Tinted Soft Contact Lens with black pupil. Pupil sizes available in 2.0 mm to 12.5 mm diameter.
