P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) for daily wear are spherical lenses indicated for the correction of refractive error in not-aphakic persons with otherwise non-diseased eyes with myopia ranging from -0.00 diopters to -10.00 diopters.
The lenses may be worn by persons who exhibit refractive astigmatism of 1.50 diopters or less where the astigmatism does not interfere with visual acuity. The lenses are available clear or tinted and may be used to enhance or alter the apparent color of the eye.
Eye care practitioners may prescribe the lenses in a frequent/planned replacement program with cleaning, disinfection, and scheduled replacement. The lenses are intended for daily wear and are to be replaced every three months (quarterly). When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
The P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) is manufactured using the cast molding method. The hydrophilic characteristics allow aqueous solutions to enter the lens. The lenses are fabricated from polymacon, which is a random copolymer of 2-hydroxyethyl methacrylate (HEMA) crosslinked with ethylene glycol dimethacrylate (EGDMA). The co-polymer consists of 62% polymacon and 38% water by weight when immersed in 0.9% saline solution. The polymacon name has been adopted by the United States Adopted Names Council (USAN).
The P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) is available clear or tinted for visibility using phthalocyanine blue, tinted in unique pattern to enhance or alter the apparent color of the eye. Each unique patterns may be distributed under unique or "private label" trade names. The lenses are processed to incorporate the 'listed' color additives and contain only the amount of the additive needed to accomplish the intended coloring effect. The lenses contain one or a combination of one or more of the following 'listed' color additives: C.I Reactive Black 5, Titanium Dioxide (TiO2), Carbazole Violet (i.e.,C.I Pigment Violet 23), Phthalocyanine green (i.e.,C.I PIgment Green 7), D&C Yellow No. 10, D&C Red No. 17, [Phthalocyaninato (2-)] Copper (i.e.,C.I PIgment Blue 15).
When producing the color lenses, the manufacturing process changes the specifications of the clear lens by pad-printing the color pigment(s)—entrapping the colorants in the interpenetrating network of the contact lens material—in a location that corresponds to the iris. The color pigments used are not removed by lens handling and cleaning/disinfecting procedures. Except for affecting the amount of light transmittance through the lens, the coloring process does not alter the original characteristics of the clear, pre-tinted lens.
Eye care practitioners may prescribe the lenses in a frequent/planned replacement program with cleaning, disinfection, and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
The provided text is a 510(k) clearance letter for contact lenses. While it details the device, its intended use, and substantial equivalence to a predicate device, crucial information regarding acceptance criteria for AI/algorithm performance and the study that proves the device meets the acceptance criteria (specifically in the context of AI/algorithm evaluation) is not present.
The document focuses on the physical and biological properties of contact lenses and manufacturing processes, not on an AI or algorithmic component that would require a study with an AI-specific acceptance criterion, ground truth establishment, or MRMC studies. The "Non-Clinical Test Conclusion" section primarily refers to biocompatibility, shelf life, and physicochemical/mechanical properties testing, all of which are standard for contact lenses and do not involve AI performance evaluation.
Therefore, I cannot fulfill the request as the input document does not contain the necessary information about AI/algorithm performance.
If this were a document for an AI-powered medical device, the information would typically be found in dedicated sections detailing "Clinical Performance Study," "Software Verification and Validation," or similar.
§ 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.
