    Device Description

    Menicon Progent Protein Remover for Rigid Gas Permeable Contact Lenses is the mixture of two sterile solutions, Progent A (active ingredient, sodium hypochlorite) and Progent B (active ingredient, potassium bromide). Progent A and B are mixed in a Progent Vial. Menicon Rinse solution is used once the lens soaking cycle is complete. The Progent treatment is recommended every two weeks. The frequency may vary according to the condition of your lens. Follow your eye care professional's directions (to a maximum of every 5 days).

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the "Menicon Progent Protein Remover for Rigid Gas Permeable Contact Lenses." However, it explicitly states that no new clinical or non-clinical studies were performed for this particular submission (K173136).

    The device's clearance is based on its prior approvals and the fact that there are no product formulation changes. Therefore, the device's acceptance criteria and the study that proves it meets those criteria are established through substantial equivalence to predicate devices (Boston Cleaner and Boston Advance Cleaner) based on historical data, not new studies presented within this document.

    As such, I cannot provide a table of acceptance criteria and reported device performance from a new study conducted for this 510(k) submission, nor can I detail sample sizes, expert qualifications, or adjudication methods for studies not conducted as part of this submission. The document explicitly states:

    • "Non-clinical studies were unnecessary for this application. Menicon Progent Protein Remover has been cleared in prior applications. There are no product formulation changes made in this application therefor no non-clinical studies were required." (Page 4)
    • "Clinical studies were unnecessary for this application. Menicon Progent Protein Remover has been cleared in prior applications. There are no product formulation changes made in this application therefor no clinical studies were required." (Page 4)

    The "Conclusion" section on page 4 further reinforces this by stating: "Based upon the product history and data presented, the Menicon Progent Protein Remover can be used as safely and as effectively as the Boston Cleaner and the Boston Advance Cleaner."

    Therefore, the requested information points regarding new studies (sample sizes, expert qualifications, adjudication, MRMC studies, standalone performance, training set details) are not applicable to the immediate content of this 510(k) summary as no such new studies were performed. The acceptance criteria essentially stem from the historical performance and regulatory compliance of the predicate devices and the Menicon Progent Protein Remover's prior clearances.

    AI/ML Overview

    The provided 510(k) summary for Menicon Progent Protein Remover for Rigid Gas Permeable Contact Lenses focuses on establishing substantial equivalence to a previously cleared device (K002140) and to Boston® Cleaner. It describes the product, its indications for use, and a high-level overview of testing performed.

    However, the document does not include detailed information regarding specific acceptance criteria, comprehensive study results, sample sizes for test or training sets, expert qualifications for ground truth establishment, or multi-reader multi-case (MRMC) comparative effectiveness studies. This type of information is typically found in the full submission, not always in the public-facing summary.

    Based on the provided text, here's what can be extracted and what is missing:


    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria:
    The document does not explicitly state quantitative acceptance criteria (e.g., specific thresholds for protein removal efficiency, irritation levels, or equivalence metrics). The primary "acceptance" described is the claim of substantial equivalence to predicate devices.

    Reported Device Performance:
    The document states that "The applicant performed toxicological testing and clinical testing of the instructions for use to support the claim of substantial equivalence." No specific performance metrics (e.g., protein removal percentage, irritation scores, or other quantitative results) are provided in this summary.


    2. Sample Size Used for the Test Set and Data Provenance

    The document states "clinical testing of the instructions for use" was performed, but does not specify the sample size for this clinical testing or any "test set."
    It also does not specify the data provenance (e.g., country of origin, retrospective or prospective nature).


    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

    The concept of "ground truth" and "experts" as typically understood in AI/ML performance evaluation (e.g., for image interpretation) is not applicable in this context. This device is a contact lens care product, and its performance evaluation would likely involve objective laboratory tests (e.g., measuring protein removal) and clinical trials assessing safety and efficacy (e.g., lens comfort, ocular health, user compliance with instructions). These types of studies might involve clinicians, but not in the role of establishing "ground truth" for a machine learning algorithm.


    4. Adjudication Method for the Test Set

    The concept of an "adjudication method" (e.g., 2+1, 3+1) is not applicable in this context, as it relates to expert disagreement resolution in diagnostic studies, not to the evaluation of a contact lens cleaning solution.


    5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done

    No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices (e.g., AI in radiology) where multiple human readers interpret cases with and without AI assistance. This device is a physical product for lens care.


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

    No, a standalone algorithm performance study was not done. This concept is relevant for AI/ML algorithms. This device is a chemical solution.


    7. The Type of Ground Truth Used

    As mentioned, "ground truth" in the context of AI/ML evaluation is not applicable here. The "truth" for this device's performance would be established through:

    • Laboratory testing: Objective measurements of protein removal effectiveness using standardized methods.
    • Toxicological testing: Evaluation of the chemical's safety and potential for irritation.
    • Clinical testing: Assessment of patient comfort, ocular health, and compliance when using the product as directed.

    8. The Sample Size for the Training Set

    The concept of a "training set" is not applicable here, as this device is a chemical solution and not an AI/ML algorithm.


    9. How the Ground Truth for the Training Set was Established

    The concept of "ground truth for a training set" is not applicable here, as this device is not an AI/ML algorithm.


    Summary of what is present and what is missing based only on the provided text:

    The document clearly states the intent to establish substantial equivalence for a protein remover for RGP contact lenses. It mentions that toxicological testing and clinical testing of the instructions for use were performed to support this claim. However, it does not provide any details about the methodologies, specific results, sample sizes, or quantitative acceptance criteria for these tests. The bulk of the information requested (related to AI/ML performance evaluation) is not relevant to this type of device.
