AI/ML Overview

The provided text is a 510(k) Premarket Notification for contact lenses. It describes the device, its indications for use, and a comparison to predicate devices to establish substantial equivalence.

Based on the nature of this document (a 510(k) for contact lenses), it focuses on demonstrating equivalence to existing legally marketed devices, rather than a clinical study evaluating the performance of an AI-powered diagnostic device against specific acceptance criteria in the way you've outlined. Therefore, many of the requested data points (sample sizes for test/training sets, number/qualifications of experts, adjudication methods, MRMC studies, standalone performance, ground truth types) are not applicable or not present in this type of submission.

However, I can extract information related to the device's technical specifications and how they compare to the predicate devices, which serves as the "acceptance criteria" in this context for demonstrating substantial equivalence.

Here's the closest interpretation of your request based on the provided document:

Acceptance Criteria and Device Performance (for Substantial Equivalence)

For a 510(k) submission, "acceptance criteria" are generally met by demonstrating that the new device is as safe and effective as a legally marketed "predicate device," without raising new questions of safety or effectiveness. This is done by comparing various attributes. The table below outlines key comparative data presented to establish substantial equivalence rather than explicit "acceptance criteria" in the context of a clinical study.

Study Information (as applicable for a 510(k) for contact lenses)

  1. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

    • Test Set Sample Size: Not applicable in the context of an "AI test set." The "test" for this device is primarily a comparison of its physical, chemical, and optical properties, and safety (toxicology), rather than a clinical performance study with a patient population and ground truth.
    • Data Provenance: The data primarily comes from laboratory testing (e.g., transmittance measurements, Dk, toxicological assays) and engineering specifications. Country of origin not specified, but the submitter is in Scottsville, NY, USA. The data is prospective as it pertains to the newly developed device and its characteristics.
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

    • Not applicable. "Ground truth" in the clinical sense is not established by experts for this type of device comparison. The "truth" is based on objective scientific measurements and established safety standards.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

    • Not applicable. There is no adjudication in the sense of expert consensus on diagnostic outcomes.
  4. 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 not an AI-powered diagnostic device.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Not applicable. This is not an algorithm. The device's standalone performance is its physical and chemical properties and safety.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

    • The "ground truth" for the device comparison is based on objective laboratory measurements (e.g., refractive index, % transmittance, water content, oxygen permeability, cytotoxicity, ocular irritation, systemic toxicity, leachability, extractables) and adherence to established material and design specifications that have been previously deemed safe and effective for predicate devices.
  7. The sample size for the training set:

    • Not applicable. This is not an AI/ML device that requires a training set.
  8. How the ground truth for the training set was established:

    • Not applicable.
