Intended Use

The VISTAKON® (galyfilcon A) Contact Lens is indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia) in aphakic or not-aphakic persons with non-diseased eyes who may have 1.00D or less of astigmatism. The VISTAKON® (galyfilcon A) Multifocal Contact Lens is indicated for daily wear for the correction of distance and near vision in presbyopic, aphakic or not-aphakic persons with non-diseased eyes who may have 0.75 D of astigmatism or less. The VISTAKON® (galyfilcon A) Toric Contact Lens is indicated for daily wear for the correction of visual acuity in aphakic or not-aphakic persons with non-diseased eyes that are hyperopic or myopic and may have 10.00 D of astigmatism or less. The VISTAKON® (galyfilcon A) Toric-Multifocal Contact Lens is indicated for daily wear for the correction of distance and near vision in presbyopic aphakic or not-aphakic persons with non-diseased who may have 10.00 D of astigmatism or less. VISTAKON® (galyfilcon A) UV Blocking Contact Lenses help protect against transmission of harmful UV radiation to the cornea and into the eye. Eye Care Practitioners may prescribe the lenses either for single-use disposable wear or frequent/planned replacement wear with cleaning, disinfection and scheduled replacement (see "Wearing Schedule"). When prescribed for frequent/planned replacement wear, the lenses may be disinfected using a chemical disinfection system only.

Device Story

VISTAKON (galyfilcon A) contact lens; hemispherical or hemitoric shell; copolymer of 2-hydroxyethyl methacrylate, (3-methacryloxy-2-hydroxypropyloxy) propylbis(trimethylsiloxy)methylsilane, N,N-dimethylacrylamide, polyvinylpyrrolidone, mPDMS-monomethacrylate, and 2-propenoic acid, 2-methyl-, 1,2-ethandiyl ester. Available as spherical, multifocal, toric, and toric-multifocal designs; includes optional blue visibility tint and benzotriazole UV-absorbing monomer. Supplied sterile in buffered saline. Prescribed by eye care practitioners for daily wear; single-use or frequent/planned replacement. Benefits include vision correction and UV radiation protection. Clinical decision-making based on practitioner assessment of refractive error and ocular health.

Clinical Evidence

Three-month clinical study; at least 50 myopic patients; 2:1 ratio of subject device to predicate. Evaluated adverse reactions, keratometry, discontinuations, and unscheduled replacements. Results demonstrated similar performance in vision, health, comfort, and fit compared to concurrent controls.

Technological Characteristics

Material: galyfilcon A (53% polymer, 47% water). Group I (low water, nonionic). UV blocker: benzotriazole monomer (transmittance <1% UVB, <10% UVA). Form factor: hemispherical/hemitoric shell. Sterilization: sterile, buffered saline solution. Connectivity: N/A.

Indications for Use

Indicated for daily wear correction of refractive ametropia (myopia/hyperopia) in aphakic or non-aphakic persons with non-diseased eyes. Specific astigmatism limits apply: spherical (≤1.00D), multifocal (≤0.75D), toric/toric-multifocal (≤10.00D). Multifocal/toric-multifocal indicated for presbyopia.

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.
