ISENS (polymacon) Spherical and Toric Daily Wear Soft Contact Lenses (Clear and Tinted)

{1}------------------------------------------------

### Equivalent Devices:

ISENS (polymacon) Spherical and Toric Daily Wear Soft (hydrophilic) Contact Lenses (Clear and Tinted) are substantially equivalent to the following predicate devices:

Predicate devices:

- "Biomedics38" . By Coopervision PMA number; P780007
- . "Contaflex 38" By Contamac Ltd. 510(k) number; K023987
- "Aquamax" . By Pegavision Corporation 510(k) number; K123973

### Device Description:

The ISENS soft contact lenses are hemispherical shells with molded spherical base curves and molded front surfaces. All lenses containing dioptric powers outside +/- 10.00 D and toric lenses are lathe-cut to specified R.J. The ISENS soft contact lenses are fabricated from polymacon, which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution.

The nonionic lens material, (polymacon) is a hydrophilic polymer of 2-Hydroxyethyl methacrylate (2-HEMA) and cross-linked with ethylene glycol dimethacrylate (EGDMA), plus an initiator. The co-polymer consists of 62% polymacon and 38% water by weight when immersed in saline solution. The (polymacon) name has been adopted by the United States Adopted Names Council (USAN).

ISENS lenses are available clear, visibility tinted, and cosmetically tinted. Lenses are tinted with one or a combination of one or more of the following 'listed' color additives: D&C Red 17, D&C Violet 2, D&C Yellow 10, Titanium Dioxide, Iron Oxide (Red), [Phthalocyaninato(2-)] Copper, Phthalocyanine Green, Carbazole Violet, Reactive Blue 19, and C.I. Reactive black 5. Lenses that contain a unique tinting pattern are subsequently processed to incorporate the 'listed' color additives, and contain only the amount of color additive needed to accomplish the intended coloring effect. When producing the cosmetic tinted lenses, the manufacturing process alters and/or changes the specifications to the clear version of a contact lens by affixing a listed reactive color additive in the center of the contact lens (between layers of contact lens material) in a location that corresponds to the iris. As part of the manufacturing process, the lenses containing the color additives are thoroughly washed to remove unbound reactive color additives. The color additives used are not removed by lens handling and cleaning/disinfecting procedures. Except for affecting the amount of light transmittance through the lens, the coloring process does not alter the original characteristics of the pre-tinted lens. The cosmetic tinting pattern has a standard Clear Pupil diameter of 6.0 mm.

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

In the hydrated state, the lens conforms to the curvature of the eye covering the cornea and extending slightly beyond the limbus forming a transparent or colored optical surface. The (polymacon) soft hydrophilic contact lens has a spherical back surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye. If the lens dries out, it will become hard and appear somewhat warped; it will return to its proper configuration when completely rehydrated in the proper storage solution.

The physical properties of the lens are:

| Refractive Index | 1.43 |
|-----------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------|
| Light Transmission (clear) | greater than 96% |
| Light Transmission (tinted) | greater than 96% (at clear region corresponding to pupil,<br>standard 6.0 mm diameter);<br>Opaque or 0-10% (at tinted region corresponding to iris) |
| Surface Character | hydrophilic |
| Water Content | 38±2% |
| Specific Gravity | 1.17 (hydrated) |
| Oxygen Permeability | $12.48 \times 10^{-11}$ (cm²/sec)(mlO₂)/(ml x mmHg @ 35°C)) (revised<br>Fatt method) |

The hydrophilic characteristics allow aqueous solution to enter the lens, and in its fully hydrated state the lens is approximately 38% water by weight. The lenses will be manufactured in spherical and toric configurations with the following features and properties:

| Chord Diameter: | 12.80 mm to 15.00 mm |
|-------------------------|--------------------------------------------------------|
| Center Thickness: | 0.050 mm to 0.210 mm |
| Base Curve: | 8.0 mm to 9.8 mm |
| Power Range | |
| Cast-molded: | -10.00D to +10.00D in 0.25D steps |
| Lathe-cut: | -20.00D to -10.00D & +20.00D to +10.00D in 0.25D steps |
| Cylinder Power (Toric): | -0.25D to -4.00D in 0.25D steps (lathe-cut) |
| Cylinder Axis (Toric): | 10° to 180° in 10° steps |

Cast-molded lenses ISENS lenses are supplied sterile in blister packages with a base made from polypropylene and a laminated foil seal on top. Lathe-cut ISENS lenses are supplied sterile in vials containing saline solution with preservative Polyhexamethylene Biguanide (PHMB). Blister package and vial labeling is printed with the appropriate lot numbering, expiration dating, and lens parameter identification. Expiration dating has been established based on studies of product stability, package integrity, and validation of the sterilization process.
