Eyecare practitioners may prescribe the lens for daily wear in a Frequent Replacement Program. The lenses may be disinfected using heat, chemical or hydrogen peroxide disinfection systems. ## Device Story Hemispherical soft contact lens; manufactured from polymerized HEMA crosslinked with EGDMA; designed to fit over corneal surface. Corrects refractive ametropia (myopia, hyperopia, astigmatism) by providing corrective power corresponding to eye's refractive needs. Features base curve, optical zone (>6mm), secondary/tertiary curves, and beveled edges for centration and comfort. Prescribed by eyecare practitioners for daily wear, including frequent replacement programs. Patient self-maintains via heat, chemical, or hydrogen peroxide disinfection. Benefits include improved visual acuity for patients with refractive errors. ## Clinical Evidence No clinical data provided. Substantial equivalence is based on identical material, formulation, and manufacturing processes to the predicate device. ## Technological Characteristics Material: Polymacon (HEMA crosslinked with EGDMA). Group 1, non-ionic, low water content polymer. Form factor: Hemispherical shell, 14.0 mm diameter, 8.6 mm base curve, 0.07 mm center thickness. Power range: +20.00 to -20.00D. Sterilization: Not specified (manufacturing process referenced from predicate). ## Regulatory 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. ## Predicate Devices - LifeStyle 4 Vue (polymacon) Hydrophilic Contact Lens ([K950283](/device/K950283.md), [K963001](/device/K963001.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Aspect Vision Care, Ltd. has received from the manufacturer of the LifeStyle 4-Vue (polymacon) Hydrophilic Contact Lens for Daily Wear all manufacturing information including; but not limited to, formulation, manufacturing processes (including polymerization conditions, tinting process, lens parameter tolerances, sterilization and packaging, quality control/quality assurance, established shelf life data, shelf life protocol) necessary to manufacture the devices, which are the subject of K963001 and K950283. Aspect Vision Care, Ltd. has also received from The LifeStyle Company, Inc. the right to reference its premarket notifications, K950283 and K963001. In addition, Aspect Vision Care, Ltd. will manufacture these devices at the same manufacturing location as the predicate devices. This lens is in Group 1, non-ionic, low water content polymers as established by the FDA and located in the Guidance Document for Daily Wear Contact Lenses, Revised Edition May 1994. The physical, optical, and chemical properties of the FREQUENCY 38 (polymacon) Hydrophilic {1} FROM : Panasonic FAX SYSTEM PHONE NO. : Apr. 16 1997 10:23AM P4 Contact Lens for Daily Wear (clear and tinted) are equivalent to those of the LifeStyle 4 Vue (polymacon) Soft Contact Lens for Daily Wear (clear and tinted). ## DESCRIPTION of the DEVICE: Soft contact lenses are hemispherical shells manufactured of polymerized material of HEMA crosslinked with EGDMA which yield the appearance of lenses which are designed to fit over the corneal surface of the eye. These lenses are designed with varying base curves which conform to the shape of the radius of the cornea and center over the apex of the cornea to provide corrective refraction for functional conditions of the eye including myopia (nearsightedness), hyperopia (farsightedness) and astigmatism (multiple foci). Each lens provides corrective power which is to correspond to the refractive power of the eye to which it is being treated. Each lens is designed with a base curve on the internal side of the lens and an optical zone in the center of the lens which is generally of a diameter greater than 6mm. Secondary and tertiary curves as well as beveled edge configurations are built into the lens for the purpose of aiding in lens centration and comfort. ## INDICATIONS FOR USE: **Device Name:** FREQUENCY 38 (polymacon) Hydrophilic Contact Lens for Daily Wear (clear and tinted) The FREQUENCY 38™ (polymacon) Hydrophilic Contact Lens (clear and tinted) is indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia) in aphakic and not-aphakic persons with non-diseased eyes that may exhibit astigmatism up to 2.00 Diopters that does not interfere with visual acuity.
