The document describes contact lenses and their physical properties and intended use. There is no mention of any computational or analytical capabilities that would suggest the use of AI or ML.
No
The device is indicated for correcting visual acuity in non-diseased eyes, not for treating any medical condition or disease.
No
This device is a contact lens intended for correcting visual acuity, not for diagnosing medical conditions.
No
The device description clearly describes physical contact lenses made of a hydrophilic copolymer with specific dimensions and physical properties. There is no mention of software as the primary component or function of the device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the correction of visual acuity in the eye. This is a direct interaction with the patient's body for a therapeutic purpose (correcting vision), not for examining specimens derived from the human body to provide information for diagnosis, monitoring, or compatibility testing.
- Device Description: The description details the physical properties and materials of a contact lens, which is a medical device placed on the surface of the eye.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological specimens (blood, urine, tissue, etc.)
- Providing diagnostic information
- Using reagents or calibrators
- Performing tests in a laboratory setting
The device is clearly a medical device intended for direct use on the eye to improve vision.

Intended Use / Indications for Use
The DuraSoft 2 FreshLook Colors (phemfilcon A) Soft (hydrophilic) Contact Lenses and the DuraSoft 2 FreshLook LiteTint (phemfilcon A) Soft (hydrophilic) Contact Lenses are indicated for daily wear in the correction of visual acuity in aphakic and not-aphakic persons with non-diseased eves that are revopic (nearsighted) or hyperopic (farsighted) and may exhibit astigmatism of 0.75 diopters (D) or less that does not interfere with visual acuity.
The lenses indicated are for Daily Wear (for available powers see Lens Description Section). Eve care practitioner may prescribe the lens for either single-use disposable daily wear or for frequent replacement wear for daily use, with cleaning, rinsing, disinfection and scheduled replacement from one to 14 days of use. (See Wear Schedule Section for additional information.) When prescribed for frequent replacement wear, the lens must be disinfected using either chemical or heat disinfection systems.

Device Description
The DuraSoft 2 FreshLook Colors (phemfilcon A) Soft (hydrophilic) Contact Lenses and DuraSoft 2 FreshLook LiteTint (phemfilcon A) Soft (hydrophilic) Contact Lenses are hemispherical shells of the following dimensions:
Chord Diameter: 12.0 to 15.0 mm
Center Thickness: 0.08 to 0.56 mm (Varies with power)
Base Curves: 7.80 to 9.00 mm
Powers: -20.00 Diopters to +20.00 Diopters
The lens material (phemfilcon A) is a hydrophilic copolymer of 2-hydroxyethy) methylcrylate and 2ethoxyethyl methacrylate. The DuraSoft 2 FreshLook Colors (phemfilcon A) Soft (hydrophilic) Contact Lenses are made by modifying the clear lens by affixing a colored pigment on that portion of the front surface of the lens which corresponds to the iris. The colored pigments consist of the following color additives listed in the Color Additive Provisions of the Code of Federal Requilations 21 CFR Section 706. All colored lenses contain iron oxides, titanium dioxide and [phthalocyaninato (2-1)] copper. In addition, the green lens contains chromium oxide and the violet lens contains carbazole violet. The DuraSoft 2 FreshLook Colors (phemfilcon A) Soft (hydrophilic) Contact Lenses are available in the following opaque colors: Blue, Green, Hazel and Violet. The DuraSoft 2 FreshLook LiteTint (phemfilcon A) Soft (hydrophilic) Contact Lenses is tinted green with the color additive, phthalocyanine green for easy visibility for handling.
The physical properties of the lenses are:
Specific Gravity: 1.176
Refractive Index: 1.440
Light Transmittance:
FreshLook LiteTint: 95% minimum
FreshLook Colors: 97% minimum
Surface Characteristics: Hydrophilic
Water Content: 38%
Optical Zone (FreshLook Colors): 5 mm
(FreshLook LiteTint): 5 mm to 9 mm (Varies with power)
Oxygen Transmissibility: Dk/L = 12.9 x 10-9 ml O2 cm@ 35°C sec ml mm Hg

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Preclinical testing including testing for cytotoxicity using the agarose overlay method; systemic toxicity in mice; and a primary ocular irritation study in the rabbit have established that minor changes in formulation to enhance molding characteristics have no detrimental affect on the lens material as manufactured.

§ 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.

General Use Instructions
The DuraSoft 2 FreshLook Colors (phemfilcon A) Soft (hydrophilic) Contact Lenses and the DuraSoft 2 FreshLook LiteTint (phemfilcon A) Soft (hydrophilic) Contact Lenses are available as Spherical Contact Lenses. The lens wearing schedule may be prescribed for either Disposable Daily Wear or Frequent Replacement Wear for daily use.

2
In the Disposable program, patients should be instructed to dispose of the lenses at each daily removal and to use lens care products only on an emergency basis.
In the Frequent Replacement Program, the lens wearing time prescribed by the eye care practitioner is for daily wear from 1 to 14 days. Each time the lens needs to be removed before the replacement time has elapsed, the lens must be cleaned, rinsed, and disinfected prior to placing it back on the eye. Wesley-Jessen recommends that the lens be discarded and replaced with a new lens every 2 weeks, or as recommended by the eye care practitioner. The eye care practitioner is encouraged to determine the wearing schedule based on the response of the patient.
