The physical / optical properties of the lens are:

Property: Specific Gravity, BOSTON EQUALENS II: 1.24
Property: Refractive Index, BOSTON EQUALENS II: 1.423
Property: Light Absorbance (Absorbance Units/Inch), BOSTON EQUALENS II: 9.4 Blue, 4.8 Green
Property: Water Content, BOSTON EQUALENS II: <1%
Property: Oxygen Permeability (Dk), BOSTON EQUALENS II: 127* (gas to gas), 85** (ISO/Fatt)

AI/ML Overview

The provided text describes a 510(k) summary for the BOSTON® EQUALENS® II (oprifocon A) Rigid Gas Permeable Contact Lenses. It does not contain information about acceptance criteria or a study proving that a device meets those criteria in the context of AI/ML performance evaluation.

Instead, this document is a regulatory submission for a medical device (contact lenses) based on substantial equivalence to a predicate device. This means the manufacturer is asserting that their new contact lens is as safe and effective as a previously approved contact lens, based on its physical/optical properties and intended use.

Therefore, I cannot fulfill your request for information related to acceptance criteria, device performance tables, sample sizes, expert ground truth, MRMC studies, or standalone algorithm performance, as these concepts are not addressed in the provided text, which pertains to a traditional medical device approval process, not an AI/ML device evaluation.

The text does give information on:

Device Description: Physical/optical properties of the lens material.
Indications for Use: What the contact lens is intended to correct.
Predicate Device: The existing device to which the new device is compared for substantial equivalence.
Regulatory Status: The FDA's determination of substantial equivalence.

Without details on an AI/ML device and its associated performance study, I cannot generate the requested table or paragraphs.

Dear Ms. Ketchum:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
