    Device Description

    The IntelliWave1, Soft Daily Wear Contact Lenses are fabricated from (Acofilcon B), which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this matcrial allows the lens to become soft and pliable when immersed in an aqueous solution. The non-ionic lens material, (acofilcon B) is a terpolymer based on high purity Giycerol Methacrylate 2,3-Dihydroxypropyl Methacrylate (GMA), with N-vinyl-2-pyrrolidone (NVP), methy] methacrylate (MMA), and 2-hydroxyethyl methacrylate (2-HEMA) and cross-linked with Diallyl Maleate (DAM). It consists of 51% acofilcon B and 49% water by weight when immersed in normal saline solution buffered with sodium tetraborate. The lens material is available in clear and with a blue visibility-handling tint, Color additive 'Reactive Blue 4' 21 CFR part 73.2121.

    The IntelliWave2, Soft Daily Wear Contact Lenses are fabricated from (Hioxifilcon B), which in the dry (unhydrated) state may be machined and polished.

The non-ionic lens material, hioxifilcon B is a copolymer of 2-hydroxyethyl methacrylate (2-HEMA) and 2,3-Dihydroxypropyl Methacrylate (Glycerol Methacrylate, GMA) and cross-linked with ethylene glycol dimethacrylate (EGDMA). It consists of 51% hioxifilcon B and 49% water by weight when immersed in normal saline solution buffered with sodium tetraborate. The lens material is available clear and with a blue visibility handling tint, phthalocyanato (2) - (copper).

    AI/ML Overview

    The provided text is a 510(k) Summary for contact lenses and does not describe a study that uses acceptance criteria and reports device performance in the way typically seen for AI/ML devices or diagnostic tools. Instead, this document focuses on demonstrating substantial equivalence to existing predicate devices.

    Therefore, many of the requested points related to a study, ground truth, expert review, and AI performance metrics are not applicable here.

    Here's an analysis based on the provided document:

    Acceptance Criteria and Reported Device Performance

    The concept of "acceptance criteria" and "reported device performance" in this 510(k) summary is centered on demonstrating that the new devices (IntelliWave1 and IntelliWave2 contact lenses) are substantially equivalent to their predicate devices. The acceptance criteria for substantial equivalence are met when the new devices have the "same as predicate device" characteristics across several key attributes.

    Table of Acceptance Criteria and Reported Device Performance:

    Note on Water Content: The document states the IntelliWave lenses have 49% water content, while the predicate devices are listed with 48.0%. However, the "same as predicate device" is checked for the water content category, and slight numerical differences within an acceptable range for that category (Group #1 < 50% Water) are typically deemed acceptable for substantial equivalence. The key is that they fall within the same classification group.

    Study Details (or lack thereof for AI/ML)

    1. Sample size used for the test set and the data provenance: This document does not describe a "test set" in the context of an AI/ML study. The basis for safety and effectiveness is presented as being substantially equivalent to legally marketed predicate devices, relying on their established safety profile (pre-clinical toxicology, clinical study data from the predicate devices, manufacturing/chemistry data). No specific sample size for a new clinical study for the IntelliWave lenses is detailed here as the primary means of demonstrating performance. The provenance of the predicate device data is not specified in this summary. It would be historical data for those predicate devices.

    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. This is not an AI/ML diagnostic device requiring expert-established ground truth. The "ground truth" for contact lenses is established through their physical and chemical properties, and their performance in clinical trials (which would have been conducted for the predicate devices).

    3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.

    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-assisted 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.

    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc): The "ground truth" for contact lenses lies in their material properties (water content, oxygen permeability, specific gravity, refractive index, etc.), biocompatibility, and clinical performance (visual acuity correction, comfort, absence of adverse events). This is derived from standard materials science, manufacturing quality control, and historical clinical data for the specific type of device and materials.

    7. The sample size for the training set: Not applicable. This is not an AI/ML device.

    8. How the ground truth for the training set was established: Not applicable.
