    The Legacy (ocufilcon D) Performance-Tinted SPHERICAL contact lenses for daily wear are indicated for the correction of refractive ametropia (myopia and hyperopia) in aphakic or not-aphakic persons with non-diseased that may exhibit astigmatism up to 2.0 diopters that does not interfere with visual acuity.

    The Legacy (ocufilcon D) Performance-Tinted TORIC Soft Contact Lenses for daily wear are indicated for the correction of refractive error in aphakic and not-aphakic persons with myopia or hyperopia and/or possesses refractive astigmatism not exceeding 5.00 diopters.

    The Legacy ( ocufilcon D) Performance-Tinted MUL TIFOCAL Soft Contact Lenses for daily wear are indicated for the correction of refractive ametropia (myopia and hyperopia) and presbyopia in aphakic persons with nondiseased eyes that may exhibit astigmatism up to 2.0 diopters that does not interfere with visual acuity.

    Daily wear replacement schedules may vary from patient and should be decided by eye care practitioners in consultation with their patients.

    Eye care practitioners may prescribe any of the above lenses for frequent/planned replacement wear, with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.

    Eye care practitioners may prescribe any of the above lenses for single use daily disposable wear. When prescribed for daily disposable wear the lens is to be discarded after each removal.

    Device Description

    The Legacy (ocufilcon D) Performance-Tinted Soft (Hydrophilic) Daily Wear Contact Lenses are hemispherical shells with molded spherical base curves and molded front surfaces. The hydrophilic characteristics allow aqueous solutions to enter the lens. The lenses are fabricated from ocufilcon D, which is a hydrophilic co-polymer of 2-Hydroxyethyl methacrylate (2-HEMA) and methacrylic acid (MAA), cross-linked with ethylene glycol dimethacrylate (EGDMA), plus an initiator. The co-polymer consists of 45% ocufiocon D and 55% water by weight when immersed in saline solution. The (ocufiocon D) name has been adopted by the United States Adopted Names Council (USAN).

    The Legacy (ocufilcon D) Performance-Tinted Soft (Hydrophilic) Daily Wear Contact Lenses are subsequently tinted to achieve different colors using permanently listed color additives that conform to 21 CFR Part 73.3121. 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: Reactive Black 5, Reactive yellow 15, Reactive orange 78, Reactive red 180.

    The Legacy (ocufilcon D) Performance-Tinted Contact Lenses are designed to aid visual performance in athletic settings. Legacy (ocufilcon D) Performance Tinted Contact Lenses enhance contrast in a wide range of outdoor light conditions. This enables the wearer to see a ball or selected objects with greater clarity than with the naked eye.

    The Legacy (ocufilcon D) Performance-Tinted Soft (Hydrophilic) Daily Wear Contact Lenses incorporate a UV absorbing monomer. The lenses block >95% in the UVB range (280mm - 315nm), and >50% in the UVA range (316nm - 380nm).

    The Legacy (ocufilcon D) Performance-Tinted Soft (Hydrophilic) Daily Wear Contact Lenses are manufactured in the sphere, toric, and multifocal design configurations.

    AI/ML Overview

    The Legacy (Ocufilcon D) Performance-Tinted Soft (Hydrophilic) Daily Wear Contact Lenses underwent a series of non-clinical tests to demonstrate their safety and effectiveness. Clinical testing was not required as the performance of ocufilcon D materials has been previously established.

    2. Sample size used for the test set and the data provenance:

    The document does not explicitly state a specific sample size for each non-clinical test. However, it indicates that "A series of preclinical testing was performed." The provenance for the non-clinical toxicology tests is that they were conducted "in accordance with the GLP regulation." The data is thus scientifically valid under 21 CFR 860.7. No specific country of origin is mentioned for the test data, beyond the general adherence to international standards (ISO). The nature of the testing is non-clinical (laboratory-based), rather than retrospective or prospective patient data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    Not applicable. This device is a contact lens and its performance criteria are based on objective physical, chemical, and biological compatibility measurements, not on expert interpretations of medical images or conditions. The "ground truth" is established by adherence to recognized international standards (e.g., ISO, ANSI) and regulatory guidelines.

    4. Adjudication method for the test set:

    Not applicable. The tests performed are objective, quantitative measurements (e.g., cytotoxicity, oxygen permeability, refractive index) rather than human-interpreted assessments requiring adjudication.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    Not applicable. This is a contact lens, not an AI-assisted diagnostic or imaging device. Therefore, MRMC studies and AI assistance are not relevant.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    Not applicable. As noted above, this is a physical medical device, not a software algorithm.

    7. The type of ground truth used:

    The "ground truth" for the non-clinical tests was established by objective standards and regulatory guidelines. This includes:

    • International Standards: ISO 10993-5 (In-Vitro Cytotoxicity), ISO 10993-11 (Systemic Toxicity), ISO 10993-10 (Acute Ocular Irritation), and ANSI Z80.20 (Ophthalmics – Contact Lenses – Standard Terminology, Tolerances, Measurements And Physicochemical Properties).
    • Regulatory Compliance: Adherence to GLP (Good Laboratory Practice) regulations and 21 CFR 73.3121 for color additives.
    • Predicate Device Comparison: The physicochemical and mechanical properties were also compared for "consistent material properties" with the primary predicate device (ILICON (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses, K182247).

    8. The sample size for the training set:

    Not applicable. This is a physical medical device, not a machine learning model requiring a training set.

    9. How the ground truth for the training set was established:

    Not applicable. As this device does not use machine learning, no training set or its associated ground truth was established.
