The Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses (Tinted, Color) 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% ocufilcon D and 55% water by weight when immersed in saline solution with polymeric wetting agents. The color additive (Pathalocyaninto(2-))Copper, Iron Oxide and Reactive Yellow 15 are added to the lens material to create a light yellow-green edge-to-edge color to make it easier to see when handling, and additionally, reduce transmittance of short wavelength light in the range of 380nm to 460nm. In addition, lenses contain a benzotriazole monomer to filter UVA and UVB radiation. The (ocufilcon D) name has been adopted by the United States Adopted Names Council (USAN).
The Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses (Tinted, Color) are available tinted for visibility, and tinted to enhance or alter the apparent color of the eye. 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 Yellow 15, Rutile TiO2, Iron Oxide, (Pathalocyaninto(2-))Copper, Carbazole Violet, Phthalocyanine Green.
When producing the color lenses, the manufacturing process changes the specifications to the light yellow-green contact lens by pad-printing the color pigment(s)—entrapping the colorants in the interpenetrating network of the contact lens material in a location that corresponds to the iris. The color pigments used are not removed by lens handling and cleaning/disinfecting procedures. Except for affecting the amount of light transmittance through the lens, the coloring process does not alter the original characteristics of the pre-tinted lens. The tinting pattern has a clear pupil diameter of 6.0 mm.
The Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses (Tinted, Color) incorporate a UV absorbing monomer. The lenses filter >95% in the UVB range (280nm - 315nm), and >80% in the UVA range (315nm - 380nm).
The Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses (Tinted, Color) are manufactured in the sphere/asphere, toric, and multifocal design configurations.
The provided FDA 510(k) clearance letter and associated summary pertain to a contact lens device, the Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lens (Tinted, Color). It's important to note that this document describes the device as a "Soft (Hydrophilic) Contact Lens," which is a device type, not an AI/ML algorithm. Therefore, many of the typical acceptance criteria and study parameters related to AI/ML device performance (such as sensitivity, specificity, MRMC studies, ground truth establishment for AI/ML, etc.) are not applicable to this type of medical device submission.
The "acceptance criteria" for a contact lens device primarily revolve around its physical, chemical, and biological properties, as well as its safety and functionality for human use, established through non-clinical (laboratory) testing and comparisons to predicate devices. The study proving these criteria are met is typically a combination of non-clinical bench testing and demonstrating substantial equivalence to an already marketed predicate device.
Here's the information based on the provided document, restructured to address your points where applicable:
1. A table of acceptance criteria and the reported device performance
For a contact lens, explicit "acceptance criteria" are often derived from recognized standards (like ANSI Z80.20 mentioned) and the performance of predicate devices. The reported device performance is compared against these and is generally expected to be within acceptable tolerances or equivalent to the predicate.
| Parameter | Acceptance Criteria (Implicitly from Standard/Predicate) | Reported Device Performance (Aurora) |

2. Sample size used for the test set and the data provenance
The document does not specify a "test set" in the context of an AI/ML algorithm for image analysis or diagnostics. Instead, the "testing" refers to a series of non-clinical (laboratory) studies:
- Toxicology: "All non-clinical toxicology tests were conducted in accordance with the GLP regulation." This includes In-Vitro Cytotoxicity, Systemic Toxicity, and Acute Ocular Irritation tests. The sample sizes for these biological tests would be defined by the relevant ISO standards (ISO 10993-5, ISO 10993-11, ISO 10993-23) but are not explicitly reported in this summary.
- Shelf Life: Testing was performed to evaluate stability, sterility, and package integrity. Sample sizes are not specified for this summary.
- Physicochemical & Mechanical Properties: Tests for refractive index, water content, Dk, % transmission, tensile strength, modulus, % elongation to break, specific gravity, and polymerization residuals. Sample sizes are not specified.
Data Provenance: The studies were non-clinical, implying laboratory-based testing rather than patient data from a specific country. They were conducted under "Good Laboratory Practice (GLP) regulations," indicating a controlled, high-quality laboratory environment. There is no mention of retrospective or prospective patient data from a clinical test set.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not applicable as the device is a contact lens, not an AI/ML diagnostic or image analysis device requiring expert-established ground truth on a test set of images or clinical cases. The ground truth for device properties is established by scientific measurement and adherence to defined standards.
4. Adjudication method for the test set
This information is not applicable for the same reasons as point 3. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in clinical or image-based studies, which are not described here.
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
This information is not applicable. An MRMC study is relevant for AI/ML diagnostic devices where human readers (e.g., radiologists) interpret cases with or without AI assistance. This device is a contact lens. The document explicitly states: "Clinical testing is not required. The clinical performance of soft (hydrophilic) contact lenses manufactured from (ocufilcon D) materials has been demonstrated previously."
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable. This device is a contact lens, not an AI/ML algorithm.
7. The type of ground truth used
For this contact lens device, the "ground truth" (or basis for evaluation) comes from:
- Established scientific standards and methodologies: For physicochemical properties (e.g., water content, Dk, light transmission) and mechanical properties (e.g., tensile strength, modulus).
- Biological safety standards: Adherence to ISO 10993 series for biocompatibility (cytotoxicity, systemic toxicity, ocular irritation).
- Comparison to a legally marketed predicate device: "Substantial equivalence" is demonstrated by showing that the new device has the same fundamental scientific technology, materials, and performs comparably to a predicate device, which itself has established safety and effectiveness.
8. The sample size for the training set
This information is not applicable. This device is a contact lens, not an AI/ML algorithm that requires a "training set."
9. How the ground truth for the training set was established
This information is not applicable for the same reason as point 8.
