Intended Use

The FREQUENCY 55 (methafilcon A) 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. Eyecare practitioners may prescribe the lens for daily wear in a Frequent Replacement Program. The lenses may be disinfected using chemical or hydrogen peroxide disinfection systems.

Device Story

Hemispherical soft contact lens made of polymerized methafilcon A (HEMA crosslinked with EGDMA); designed to fit over corneal surface. Provides refractive correction for myopia, hyperopia, and astigmatism. Lens features base curves, optical zone, and beveled edges for centration and comfort. Prescribed by eyecare practitioners for daily wear, including frequent replacement programs. Patient cleans and disinfects lenses using chemical or hydrogen peroxide systems. Benefits include improved visual acuity for patients with refractive ametropia.

Clinical Evidence

No clinical data provided; substantial equivalence based on identical material, manufacturing processes, and physical/chemical properties to the predicate device.

Technological Characteristics

Material: methafilcon A (HEMA crosslinked with EGDMA). Group 4 (ionic, high water content). Dimensions: 14.0 mm diameter, 0.07 mm center thickness, 8.6 mm base curve. Power range: +20.00 to -20.00D. Form factor: hemispherical soft contact lens.

Indications for Use

Indicated for daily wear correction of myopia and hyperopia in aphakic and non-aphakic persons with non-diseased eyes; includes patients with astigmatism up to 2.00 Diopters.

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.

# 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.
