Intended Use

The Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lens is indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and 1.00 diopter (D) or less of astigmatism. Eye Care Professionals may prescribe the lenses either for single-use disposable wear or frequent/planned replacement wear with cleaning, disinfection and scheduled replacement. When prescribed for daily disposable wear, the lens is to be discarded after each removal. When prescribed for frequent/planned replacement wear, the lens may be cleaned and disinfected using a chemical disinfection system only.

Device Story

Qualis is a soft, daily-wear contact lens fabricated from linofilcon A (silicone-containing monomer/hydrophilic monomer copolymer). It acts as a refractive medium to focus light on the retina. The lens is a hemispherical shell with a molded spherical base curve and front surface. It contains a blue handling tint and a benzotriazole UV-blocking monomer. It is prescribed by eye care professionals for either single-use disposable wear or frequent/planned replacement wear (requiring chemical disinfection). The device benefits patients by providing optical correction for ametropia. It is used by the patient in a daily-wear context.

Clinical Evidence

Open-label, multi-center, randomized concurrent-control study with 91-day follow-up. 75 subjects enrolled (50 test, 25 control). Primary endpoints included biomicroscopy findings, symptoms, and vision safety measures. 73 subjects completed the study. No serious adverse events reported. Results established substantial equivalence in clinical performance between Qualis and Acuvue Vita.

Technological Characteristics

Material: linofilcon A (62% polymer, 38% water). Design: Spherical, cast-molded. UV protection: Benzotriazole monomer (blocks >95% UVB, >70% UVA). Oxygen permeability: 100 (x 10^-11). Refractive index: 1.415 (hydrated). Packaging: Injection-molded polypropylene blister. Biocompatibility testing per ISO 10993 series.

Indications for Use

Indicated for correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and ≤ 1.00 D astigmatism.

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.

Dear Bret Andre:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

### VII. PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

## Non-Clinical Performance Testing

A series of non-clinical performance tests were performed to demonstrate the safety and effectiveness of the Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lens. The results support the claim that the Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lens is substantially equivalent to the currently marketed predicate device. A summary of the results from the non-clinical studies is presented below.

## Toxicology:

All biocompatibility/toxicology tests were conducted in accordance with the GLP regulation.

- · In-Vitro Cytotoxicity: Cytotoxicity testing was performed in accordance with ISO 10993-5 with results indicating that the finished lenses and packaging materials are non-toxic.
- · Systemic Toxicity: The finished lenses and packaging materials meet the requirements of the systemic injection test in accordance with ISO 10993-11 and are considered nontoxic.
- · Acute Ocular Irritation: Acute ocular irritation testing was performed in accordance with ISO 10993-10, and the extracts from finished lenses and packaging materials produced no ocular irritation.
- · Skin Sensitization Study (Maximization Test): The skin sensitization study was conducted on the finished lenses in accordance with ISO 10993-10, and the contact lens extracts did not produce skin sensitization.
- · 22-Day Ocular Irritation: The 22-day ocular irritation test was conducted in accordance with ISO 9394 on the finished lenses, and the contact lens extracts produced no ocular irritation.

## Shelf Life:

Testing was performed to evaluate the stability, sterility, and package integrity of the Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lens over the duration of the labeled expiration date. The data presented supports establishment of the proposed shelf life.

## Solution Compatibility

The physical compatibility of Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lenses with commonly available cleaning and disinfection solutions (peroxide and MPDS) was confirmed following the methodology described in ISO 11981:2017, Ophthalmic optics -Contact lenses and contact lens care products - Determination of physical compatibility of contact lens care products with contact lenses.

{9}------------------------------------------------

510(k) Premarket Notification

## Preservative Uptake and Release

Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lenses were analyzed for uptake and release of preservatives found in lens care products. Testing was conducted according to ISO 11986:2017, Ophthalmic optics - Contact lenses and contact lens care products - Determination of preservative uptake and release. Uptake and release profiles of linofilcon A contact lenses for polyaminopropyl biguanide (PAPB) and Polyquaternium-1 (PQ-1) demonstrate sub-detection limit amounts of release at each time point evaluated.

## Performance Testing - Bench:

The following bench tests were completed: refractive index, water content, Dk, % transmission (visible & UV), tensile strength, modulus, % elongation to break, specific gravity and quantification of polymerization residuals. Results of physicochemical and mechanical property testing demonstrate consistent material properties between the Qualis (linofilcon A) Soft (Hydrophilic) Daily Wear Contact Lens and the predicate device.

## Clinical Testing

An open-label. multi-center. randomized concurrent-control study with 91-day treatment follow-up was completed. Seventy-five (75) subjects were enrolled in the study-of which 50 subjects wore the test lenses (Qualis (linofilcon A) Silicone Hydrogel Soft Contact Lens for Daily Wear) and 25 subjects wore the control lenses (Acuvue Vita (senofilcon C) Monthly Contact Lens). Seventy-three (73) of the 75 enrolled subjects completed the study. No serious adverse events were reported. The study results establish substantially equivalent clinical performance between the test (Qualis) and control (Acuve Vita) lenses with respect to biomicroscopy findings, symptoms and vision safety measures; therefore, this clinical investigation supports the claim of substantial equivalence between the two lens types with regard to clinical safety and effectiveness.
