Intended Use

AVAIRA (enfilcon A) SPHERE Soft (Hydrophilic) Contact Lenses are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity. AVAIRA (enfilcon A) TORIC Soft (Hydrophilic) Contact Lenses are indicated for the correction of visual ametropia (myopia or hyperopia with astigmatism) in aphakic and non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and astigmatic corrections from -0.25 to -10.00 diopters. DAILY DISPOSABLE: The AVAIRA (enfilcon A) Soft (hydrophilic) Contact Lenses are indicated for single-use disposable wear. FREQUENT REPLACEMENT: The AVAIRA (enfilcon A) Soft (hydrophilic) Contact Lenses are indicated for daily wear. When prescribed for planned replacement the lens may be disinfected using a chemical or hydrogen peroxide disinfecting system.

Device Story

Silicone hydrogel contact lens; hemispherical shell; enfilcon A material; incorporates phthalocyanine blue handling tint and UV blocker. Device fits over corneal surface to provide refractive correction for ametropia. Manufacturing process modification adds monomer sonication step. No changes to physical properties, dimensions, or formulation. Used by patients for daily wear; prescribed by eye care professionals. Output is visual correction; benefits patient by improving visual acuity.

Clinical Evidence

No clinical data. Bench testing only. Physicochemical studies (refractive index, total extractables, monomer residuals, ionoflux, contact angle, UV transmission, modulus, elongation, tensile strength, power conformance) demonstrated that the modified manufacturing process resulted in no significant change to lens properties.

Technological Characteristics

Silicone hydrogel (enfilcon A); non-surface treated; 46% water content; oxygen permeability 100 (cm²/sec)(ml O₂)/ml*mmHg; refractive index 1.40; base curve 8.2-9.2 mm; diameter 13.5-15.0 mm; UV blocker included; monomer sonication step added to manufacturing.

Indications for Use

Indicated for correction of ametropia (myopia/hyperopia) in aphakic and non-aphakic persons with non-diseased eyes. Sphere lenses for astigmatism ≤2.00D. Toric lenses for astigmatism -0.25 to -10.00D. Powers -20.00 to +20.00D.

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.

## Device Description:

The Avaira (enfilcon A) soft contact lens is a daily wear silicone hydrogel contact lens that is not surface treated and is characterized by a high oxygen permeability (Dk). The lens material, enfilcon A, is composed of silicone macromers cross linked with other monomers, incorporating phthalocyanine blue as an integrated handling tint. A UV blocker is added to reduce the amount of ultraviolet light transmitted into the eye. The Avaira (enfilcon A) Soft (hydrophilic) contact lenses are a hemispherical shell. This 510(k) submission covers a process modification to add a step to the preparation of the monomer mixture. The physical properties and dimensions of the finished lenses are unchanged from predicate 510(k)s.

### Intended Use:

#### SPHERICAL:

Avaira (enfilcon A) SPHERE Soft Contact lenses are indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes. The

lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.

#### TORIC:

Avaira (enfilcon A) TORIC Soft Contact lenses are indicated for the correction of ametropia (myopia or hyperopia with astigmatism) in aphakic and non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and astigmatic corrections from -0.25 to -10.00 diopters.

#### Physiochemical Studies

In-vitro studies measuring the physical, optical and chemical properties of lenses subjected to the modified manufacturing process were performed. The results show there is no significant change to the physicochemical properties of the lenses.

| Tested Characteristics | Results |
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------|
| Refractive Index, Total Extractables, Monomer<br>Residuals, Ionoflux, Contact Angle, UV Transmission,<br>Modulus, Elongation, Tensile Strength, and Power<br>Conformance | Pass |

#### Clinical Studies

In-vivo clinical studies were not required for this change, as the dimensions, formulation, lens manufacturing process, and product specifications remain the same.

#### Conclusion

#### Validity of Scientific Data

Physiochemical studies were conducted by CooperVision following scientific protocols.

#### Substantial Equivalence

The information presented in this submission establishes the substantial equivalence of the modified AVAIRA (enfilcon A) SPHERE and TORIC daily wear contact lenses to the predicate devices. The following table summarizes the substantial equivalence comparison information.
