The Largan 55 (methafilcon A) Daily Wear Soft (hydrophilic) Contact Lens is a Daily Wear Soft (hydrophilic) Contact Lens indicated for the correction of refractive ametropia (myopia and hyperopia) in phakic persons with nondiseased eyes who exhibit refractive astigmatism of 1.00D or less where the astigmatism does not interfere with visual acuity.
The Largan 55 (methafilcon A) Daily Wear Soft (hydrophilic) Contact Lens for Astigmatism is indicated daily wear for the correction of ametropia (myopia and hyperopia) with astigmatism in aphakic persons with nondiseased eyes and whose powers are from -10.00 to +3.00 diopters and astigmatic corrections are from -0.25 to -5.00 diopters.
The Largan 55 (methafilcon A) Daily Wear Soft (hydrophilic) Contact Lens for Presbyopia is indicated daily wear for the correction of ametropia (myopia and hyperopia) and emmetropia in aphakic and non-aphakic persons with non-diseased eyes and whose powers are from -10.00 to +3.00 diopters from +0.25 to +3.50 diopters. The lenses may be worn by persons who exhibit astigmatism of 1.00 diopters or less where the astigmatism does not interfere with visual acuity.
Eye care practitioners may prescribe the lens for either single-use disposable wear, or for frequent/planned replacement wear, with cleaning, disinfection, and scheduled replacement. When prescribed for single-use disposable wear, the lens is to be discarded after each removal, therefore no cleaning or disinfecting is required. When prescribed for frequent replacement, the lens may be disinfected using a chemical disinfection system only.
The Largan 55 (methafilcon A) Daily Wear Soft (hydrophilic) Contact Lens is in hemispherical flexible shells for myopia, hyperopia, astigmatisam and presbyopia. The lens is made from HEMA containing UV blocker. The composition of the lens is 45% methafilcon A and 55% water. A light blue color tinted with "reactive Blue 246" is for handling visibility purpose. Benzotriazole UV absorbing monomer is used to block UV radiation. The transmittance characteristics are 1.53% (
The provided text does not contain information about acceptance criteria and a study proving a device meets these criteria for an AI/ML medical device.
The document is a 510(k) premarket notification for a soft (hydrophilic) contact lens, specifically the "Largan 55 (methafilcon A) Daily Wear Soft (hydrophilic) Contact Lens." It focuses on demonstrating substantial equivalence to a legally marketed predicate device (CooperVision's Frequency 55 series) based on physical, chemical, and optical properties, and manufacturing process.
Therefore, I cannot extract the requested information regarding AI/ML device acceptance criteria and study details from this document. If you have a different document related to an AI/ML medical device, please provide it.
§ 886.5925 Soft (hydrophilic) contact lens.
(a)
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.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
