Spherical and Aspheric
Ethos Aquell (Hioxifilcon A) Spherical and Aspheric One-Day Soft (Hydrophilic) Contact Lenses (59% Water) are indicated for daily wear for the correction of ametropia (myopia and hyperopia) in aphakic and/or non-aphakic persons with non-diseased eyes in powers from +10.00 to -20.00 diopters. The lenses may be worn by persons who exhibit astigmatism of 1.00 diopters or less that does not interfere with visual acuity.
Toric
Ethos Aquell (Hioxifilcon A) Toric One-Day Soft (Hydrophilic) Contact Lenses (59% Water) are indicated for daily wear for the correction of ametropia (myopia or hyperopia with astigmatism) in aphakic and/or non-aphakic persons with non-diseased eyes in powers from +10.00 to -20.00 diopters and astigmatic corrections from -0.50 to -6.00 diopters.
The lenses are intended for single-use disposable wear.
The Ethos Aquell (Hioxifilcon A) One-Day Soft (Hydrophilic) Contact Lenses (59% Water) are clear, visibility-tinted and include UV blocker-containing. The lens is available in spherical, aspherical and toric designs. It is an non-ionic hydrogel lens Hioxifilcon derived from of 2-Hydroxyethylmethacrylate (2-HEMA) and 2,3-Dihydroxypropyl Methacrylate (GlycerolMethacrylate, GMA), cross-linked with ethylene glycol dimethacrylate (EGDMA) and made by photo-polymerization. It consists of 41% Hioxifilcon A and 59% water by weight when immersed in buffered solution. There are two types of buffer solution. one is borate solution (Saline 2); another one is borate solution with sodium hyaluronate (Saline 1). The lens polymer further contains a benzotriazole UV absorbing monomer and thus is able to block UV radiation. The lens is visibly tined with "Reactive Blue19" color additive, 21 CFR part 73.3121.
This document is a 510(k) summary for a contact lens, not an AI/ML medical device. Therefore, the information typically required for an AI/ML device's acceptance criteria and study proving it meets those criteria (such as sample size for test/training sets, expert consensus, MRMC studies, etc.) is not present.
The document focuses on demonstrating substantial equivalence to a previously cleared predicate device, which is the standard pathway for many medical devices, including contact lenses. This involves showing similar technological characteristics and performance through non-clinical testing.
Here's an analysis of the provided text in relation to the requested information, highlighting why certain points cannot be addressed:
1. A table of acceptance criteria and the reported device performance
The document provides a comparative table of technological characteristics between the proposed device ("Ethos Aquell (Hioxifilcon A) One-Day Soft (Hydrophilic) Contact Lenses (59% Water)") and a predicate device (K040303). This isn't strictly "acceptance criteria" in the sense of performance metrics for an AI/ML algorithm, but rather a comparison for demonstrating substantial equivalence.

NaturalVue (etafilcon A) Daily Disposable Soft (Hydrophilic) Contact Lenses are indicated for daily wear for the correction of ametropia (myopia and hyperopia) in aphakic and/or non-aphakic persons with non-diseased eyes in powers from +20.00 to -20.00 diopters. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.
NaturalVue (etafilcon A) Toric Daily Disposable Soft (Hydrophilic) Contact Lenses are indicated for daily wear for the correction of ametropia (myopia or hyperopia with astigmatism) in aphakic and/or non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and astigmatic corrections from -0.25 to -10.00 diopters.
NaturalVue (etafilcon A) Multifocal Daily Disposable Soft (Hydrophilic) Contact Lenses are indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia), and/or presbyopia in aphakic and/or non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and with non-diseased eyes who may require a reading addition of up to +3.00D. The lenses may be worn by persons who exhibit astigmatism of 2.00 diopters or less that does not interfere with visual acuity.
NaturalVue (etafilcon A) Toric Multifocal Daily Disposable Soft (Hydrophilic) Contact Lenses are indicated for daily wear for the correction of refractive ametropia (myopia and hyperopia), and/or presbyopia in aphakic and/or non-aphakic persons with non-diseased eyes in powers from -20.00 to +20.00 diopters and with non-diseased eyes who may require a reading addition of up to +3.00D. The lenses may be worn by persons who exhibit astigmatism of 10.00 diopters or less.
The lenses are intended for single-use disposable wear.
The NaturalVue (etafilcon A) Daily Disposable Soft (Hydrophilic) Contact Lenses are visibilitytinted, containing a UV blocker and are available in a spheric, toric, multifocal, and multifocal toric designs. They are manufactured by cast molding method. The device is an ionic hydrogel lens derived from etafilcon A which is a co-polymer of 2-Hydroxyethylmethacrylate (2-HEMA) and Methacrylic Acid (MAA), cross-linked with ethylene glycol dimethacrylate (EGDMA) and 1.1.1-trimethylolpropane trimethacrylate (TMPTMA) via photo-polymerization. The copolymer consists of 42% etafilcon A and 58% water by weight when immersed in normal buffered saline solution. The lenses are tinted blue using C.I. Reactive Blue 19 to make them more visible for handling. The lenses contain a UV blocker, a benzotriazole UV absorbing monomer to block UV radiation. The average transmittance characteristics of the lenses are less than 5% in the UVB range of 280-315nm and less than 30% in the UVA range of 316-380nm. Each lens is supplied sterile in a blister pack containing buffered saline solution with Tween 80, Sodium Hyaluronate, and Polyethylene Glycol.
