P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) for daily wear are spherical lenses indicated for the correction of refractive error in not-aphakic persons with otherwise non-diseased eyes with myopia ranging from -0.00 diopters to -10.00 diopters.
The lenses may be worn by persons who exhibit refractive astigmatism of 1.50 diopters or less where the astigmatism does not interfere with visual acuity. The lenses are available clear or tinted and may be used to enhance or alter the apparent color of the eye.
Eye care practitioners may prescribe the lenses in a frequent/planned replacement program with cleaning, disinfection, and scheduled replacement. The lenses are intended for daily wear and are to be replaced every three months (quarterly). When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
The P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) is manufactured using the cast molding method. The hydrophilic characteristics allow aqueous solutions to enter the lens. The lenses are fabricated from polymacon, which is a random copolymer of 2-hydroxyethyl methacrylate (HEMA) crosslinked with ethylene glycol dimethacrylate (EGDMA). The co-polymer consists of 62% polymacon and 38% water by weight when immersed in 0.9% saline solution. The polymacon name has been adopted by the United States Adopted Names Council (USAN).
The P-CON (polymacon) Soft (hydrophilic) Contact Lenses (Tinted, Color) is available clear or tinted for visibility using phthalocyanine blue, tinted in unique pattern to enhance or alter the apparent color of the eye. Each unique patterns may be distributed under unique or "private label" trade names. 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: C.I Reactive Black 5, Titanium Dioxide (TiO2), Carbazole Violet (i.e.,C.I Pigment Violet 23), Phthalocyanine green (i.e.,C.I PIgment Green 7), D&C Yellow No. 10, D&C Red No. 17, [Phthalocyaninato (2-)] Copper (i.e.,C.I PIgment Blue 15).
When producing the color lenses, the manufacturing process changes the specifications of the clear 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 clear, pre-tinted lens.
Eye care practitioners may prescribe the lenses in a frequent/planned replacement program with cleaning, disinfection, and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
The provided text is a 510(k) clearance letter for contact lenses. While it details the device, its intended use, and substantial equivalence to a predicate device, crucial information regarding acceptance criteria for AI/algorithm performance and the study that proves the device meets the acceptance criteria (specifically in the context of AI/algorithm evaluation) is not present.
The document focuses on the physical and biological properties of contact lenses and manufacturing processes, not on an AI or algorithmic component that would require a study with an AI-specific acceptance criterion, ground truth establishment, or MRMC studies. The "Non-Clinical Test Conclusion" section primarily refers to biocompatibility, shelf life, and physicochemical/mechanical properties testing, all of which are standard for contact lenses and do not involve AI performance evaluation.
Therefore, I cannot fulfill the request as the input document does not contain the necessary information about AI/algorithm performance.
If this were a document for an AI-powered medical device, the information would typically be found in dedicated sections detailing "Clinical Performance Study," "Software Verification and Validation," or similar.

This document describes the regulatory clearance of contact lenses, not a medical AI device requiring the kind of rigorous AI-specific validation outlined in your request. The provided text is a 510(k) clearance letter for contact lenses, which focuses on demonstrating substantial equivalence to a predicate device through physicochemical, biocompatibility, and clinical performance in human subjects, rather than AI model performance metrics.
Therefore, many of the requested elements for an AI device's acceptance criteria and accompanying study (e.g., sample size for test set, data provenance for AI, number of experts for ground truth, adjudication method, MRMC studies, standalone AI performance, training set details) are not applicable to this document as it does not relate to an AI device.
However, I can extract the relevant information from the provided document concerning the contact lens study and present it in a similar structured format, adapting where necessary.
Device: Pegavision (Toufilcon B) Daily Disposable Soft (Hydrophilic) Contact Lenses; Pegavision (Toufilcon B) Soft (Hydrophilic) Contact Lenses
Nature of Study: Clinical trial demonstrating substantial equivalence of a new contact lens product to an existing predicate device, focusing on safety and effectiveness for vision correction. This is not an AI device study.
1. Table of Acceptance Criteria (for Contact Lenses) and Reported Device Performance
Given this is a contact lens, the "acceptance criteria" are related to clinical efficacy (visual acuity) and safety (adverse events, slit lamp findings), and various physicochemical properties. The study aims to show non-inferiority or comparability to the predicate device rather than meeting specific numerical thresholds for many of the elements you'd expect in an AI performance table (e.g., sensitivity, specificity).
| Acceptance Criteria Category (for Contact Lenses) | Specific Metric / Criterion | Reported Device Performance |
|---|---|---|
| Clinical Efficacy (Primary Endpoint) | Corrected contact lens visual acuity of 1.0 decimal (0.0 logMAR) or better at final visit | "no difference in control group and test group." "test and control groups are comparable in corrected contact lens visual acuity." |
| Clinical Safety (Secondary Endpoints) | Absence of serious and significant adverse device events (ADE) | "no serious and significant adverse device event occurred during the conduct of the study in both control and test group." |
| Slit Lamp Findings > Grade 2 | "No subject with adverse device effects accompanying Slit Lamp Findings > Grade 2 was reported in the control group and test group." | |
| Physicochemical Properties | Met established specifications and requirements (e.g., Refractive Index, Oxygen Permeability, Water content, Light Transmittance, Mechanical Property, Shelf Life, Solution Compatibility, Preservative Uptake and Release) | "The results demonstrated that the lens met all established specifications and requirements for physical, optical, and chemical properties." (Specific values for some properties are provided in the "Technological characteristics studies" table, indicating they were assessed against the predicate). |
| Biocompatibility | Exhibit no cytotoxicity, no ocular irritation, no skin sensitization, and no acute systemic toxicity. Product does not contain any toxic or harmful substances. | "All biocompatibility tests yielded passing results, confirming that the product does not contain any toxic or harmful substances that may pose a risk to biological systems." |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size:
- Screened: 75 subjects
- Enrolled: 56 subjects (39 wore test lenses, 17 wore control lenses)
- Completed Study: 54 subjects (2 subjects in test group discontinued)
- Data Provenance: Prospective, randomized, double-blind, parallel, active-controlled clinical trial conducted in Taiwan.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Not explicitly stated for establishing "ground truth," as this was a clinical trial involving patient outcomes and examinations. Clinical assessments were likely performed by eye care professionals involved in the study (e.g., ophthalmologists, optometrists), but a specific number or their detailed qualifications are not provided in the summary. The "ground truth" for contact lenses is physiological response, visual acuity, and safety outcomes from direct patient observation.
4. Adjudication Method for the Test Set
Not explicitly stated. Clinical trials typically have protocols for adverse event reporting and assessment, often by an independent safety committee or study investigators.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC study was not done. This type of study is specifically designed for evaluating diagnostic performance of imaging modalities or AI systems where multiple readers interpret cases. This document describes a clinical trial for a contact lens, comparing direct patient outcomes between a new lens and a predicate.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done
Not Applicable. This is a physical medical device (contact lens), not an algorithm or AI system.
7. The Type of Ground Truth Used
The "ground truth" for this contact lens study was based on:
- Clinical Outcomes Data: Corrected visual acuity measurements.
- Safety Data: Adverse event reporting, assessment of slit lamp findings (direct observation of ocular health by clinicians).
- Physicochemical and Biocompatibility Test Results: Objective laboratory measurements demonstrating material properties and biological safety.
8. The Sample Size for the Training Set
Not Applicable. This is not an AI/machine learning study, so there is no training set in that context. The "training" for the device would be the manufacturing process and quality control.
9. How the Ground Truth for the Training Set Was Established
Not Applicable. See point 8.

The provided FDA 510(k) clearance letter and summary describe the safety and effectiveness studies for soft contact lenses, not an AI-powered medical device. Therefore, much of the requested information regarding acceptance criteria, ground truth, expert adjudication, MRMC studies, and standalone performance for an AI device is not applicable and not present in the document.
The document focuses on demonstrating substantial equivalence of the new contact lenses to legally marketed predicate devices through physiochemical studies, biocompatibility testing, and clinical wearer studies. The "acceptance criteria" discussed are primarily about demonstrating non-inferiority in terms of safety and effectiveness for the contact lenses when worn by human subjects, compared to existing, legally marketed lenses.
Here's an attempt to answer the questions based on the provided document, acknowledging where the requested information for AI devices is not relevant or available:
Acceptance Criteria and Study Details for BenQ Materials Corporation Contact Lenses (K242056)
This document describes the safety and effectiveness testing for soft contact lenses, which are physical medical devices, not AI software. As such, the typical "acceptance criteria" and "study that proves the device meets the acceptance criteria" for an AI device (e.g., diagnostic accuracy, sensitivity, specificity, expert adjudication, MRMC studies) are not directly applicable. Instead, the studies aim to demonstrate the non-inferiority of the new contact lenses compared to predicate devices in terms of clinical safety and efficacy in human wearers.
1. Table of Acceptance Criteria and Reported Device Performance
Given this is a physical medical device (contact lens) and not an AI device, the "acceptance criteria" are generally framed as demonstrating non-inferiority to existing predicate devices in clinical performance. The document doesn't provide specific quantitative thresholds for "acceptance criteria" in a typical AI sense (e.g., target AUC, sensitivity). Instead, it states the overall finding of "no significant difference."
| Acceptance Criteria (Conceptual for Contact Lenses) | Reported Device Performance |
|---|---|
| Safety: No significant increase in adverse reactions or hazardous, sight-threatening conditions compared to predicate device. | miacare (miafilcon A) & (miafilcon B) Lenses: "No adverse reaction was reported for both test group and control group related to hazardous, sight-threatening condition... (corneal ulcers, severe corneal abrasion > 2mm, iritis, other ocular infections or inflammations, corneal scarring, or permanent loss of vision)." "No statistic significant difference between test lens and control lens with respect to safety data including adverse reaction data, slip lamp findings, symptoms/problems/complications, Keratometry (K) readings, refractive changes (absolute value) and visual acuity (VA) data, average wearing time (AWT), discontinuations and lens replacement." |

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This section is not applicable as the study involved clinical performance trials of physical contact lenses on human subjects, not an AI device requiring expert consensus for ground truth on imaging or diagnostic tasks. The "ground truth" here is the observed clinical outcome (e.g., adverse events, visual acuity, slit lamp findings) directly measured from the study participants by eye care professionals involved in the study. The document does not specify the number or qualifications of these eye care professionals, beyond stating the studies were conducted in "3 hospitals."
4. Adjudication Method for the Test Set
Adjudication methods (e.g., 2+1, 3+1) are typically used in AI studies for resolving discrepancies in ground truth labeling by multiple experts. This concept is not applicable here. Clinical outcomes were presumably recorded by the investigators at different sites. The summary states "No statistic significant difference between test lens and control lens with respect to safety data," implying statistical comparison of observed clinical metrics between groups.
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 question is not applicable. MRMC studies are specific to evaluating human reader performance with and without AI assistance for tasks like medical image interpretation. This document describes a clinical trial evaluating the performance of contact lenses for vision correction and eye health.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This question is not applicable. "Standalone performance" refers to the algorithm's performance without human interaction for AI devices. The devices in this submission are contact lenses, which are inherently used by humans.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
The "ground truth" in these clinical studies primarily consists of:
- Clinical Outcomes Data: Direct observations and assessments from study participants during the 90-day follow-up. This includes:
- Adverse events reported and observed.
- Slit lamp findings (examinations of the eye's anterior segment).
- Symptoms/problems/complications reported by subjects.
- Keratometry (K) readings (corneal curvature).
- Refractive changes (absolute value).
- Visual acuity (VA) data.
- Average wearing time (AWT).
- Discontinuation reasons and lens replacement data.
- Visual Acuity: The ability of the CVA (Corrected Visual Acuity) to reach "equal or higher than 1.0" (presumably 20/20 or better).
- Aesthetic Effect: The color lens's ability to "enhance or alter the apparent color of the eye."
8. The Sample Size for the Training Set
This question is not applicable. "Training set" refers to data used to train an AI model. This document describes clinical trials for physical medical devices (contact lenses), not the development of an AI algorithm.
9. How the Ground Truth for the Training Set Was Established
This question is not applicable for the same reasons as #8. There is no AI training set in this submission.

The SPHERICAL/ASPHERE Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses are indicated for the correction of refractive ametropia (myopia and hyperopia) in aphakic or not-aphakic persons with non-diseased eyes that may exhibit astigmatism up to 2.0 diopters that does not interfere with visual acuity. The lens is available clear or tinted and may be used to enhance or alter the apparent color of the eye.
The TORIC Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses are indicated for the correction of refractive error in aphakic and not-aphakic persons with non-diseased eyes with myopia or hyperopia and/or possesses refractive astigmatism not exceeding 5.00 diopters. The lens is available clear or tinted and may be used to enhance or alter the apparent color of the eye.
The MULTIFOCAL Aurora (ocufilcon D) Soft (Hydrophilic) Daily Wear Contact Lenses are indicated for the correction of refractive ametropia (myopia and hyperopia) and presbyopia in aphakic or not-aphakic persons with non-diseased eyes that may exhibit astigmatism up to 2.0 diopters that does not interfere with visual acuity. The lens is available clear or tinted and may be used to enhance or alter the apparent color of the eye.
Daily wear replacement schedules may vary from patient to patient and should be decided by eye care practitioners in consultation with their patients.
Eye care practitioners may prescribe any of the above lenses for frequent/planned replacement wear, with cleaning disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
Eye care practitioners may prescribe any of the above lenses for single use daily disposable wear. When prescribed for daily disposable wear the lens is to be discarded after each removal.
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) |
|---|---|---|
| Chord Diameter | 11.00 mm to 15.00 mm (±0.20 mm tolerance) | 11.00 mm to 15.00 mm (±0.20 mm tolerance) |
| Center Thickness | 0.05 mm to 0.15 mm (Specific tolerances) | 0.05 mm to 0.15 mm (Specific tolerances) |
| Base Curve | 7.00 mm to 10.0 mm (±0.20 mm tolerance) | 7.00 mm to 10.0 mm (±0.20 mm tolerance) |
| Back Vertex Power (F'v) | +20.00D to -20.00D (Specific tolerances) | +20.00D to -20.00D (Specific tolerances) |
| Cylinder Power (F'c) | -0.25D to -4.00D (Specific tolerances) | -0.25D to -4.00D (Specific tolerances) |
| Cylinder Axis | 10° to 180° (Specific tolerances) | 10° to 180° (Specific tolerances) |
| Multifocal Add Power | +0.25D to +4.00D (±0.37 D tolerance) | +0.25D to +4.00D (±0.37 D tolerance) |
| Surface Appearance | Clear with no surface defect | Clear with no surface defect |
| Oxygen Permeability (Dk) | 19.6 (±20% tolerance) | 19.6 (±20% tolerance) |
| Light Transmission (380-780nm) | 95% (±5% tolerance) | 95% (±5% tolerance) |
| Light Transmission (380-460nm) | >75% (>75% tolerance) | >75% (>75% tolerance) |
| UV-B Transmittance | < 5 % | < 5 % |
| UV-A Transmittance | < 20 % | < 20 % |
| Water Content | 55% (±2% tolerance) | 55% (±2% tolerance) |
| Refractive Index (hydrated) | 1.410 (±0.005 tolerance) | 1.410 (±0.005 tolerance) |
| In-Vitro Cytotoxicity | Not cytotoxic | Not cytotoxic |
| Systemic Toxicity | No acute systemic toxicity | No acute systemic toxicity |
| Acute Ocular Irritation | No ocular irritation | No ocular irritation |
| Shelf Life | Stability, sterility, and package integrity maintained | Stability, sterility, and package integrity maintained over labeled expiration date |
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.

HPM38 (polymacon) Daily Wear Soft (Hydrophilic) Contact Lens is indicated for the correction of visual acuity in aphakic and not-aphakic persons with non-diseased eyes with myopia. The lens may be worn by persons who exhibit refractive astigmatism of 0.50 diopters or less where the astigmatism does not interfere with visual acuity. The lens is available tinted and used to enhance or alter the apparent color of the eye.
Daily wear replacement schedules may vary from patient and should be decided by eyecare practitioners in consultation with their patients.
Disposable Wear:
Eyecare practitioners may prescribe any of the above lenses for Daily Disposable Wear. When prescribed for Daily Disposable Wear, the lenses are not to be used with disinfecting systems as they are to be discarded after a single use.
Frequent / Planned Replacement Wear:
Eyecare practitioners may prescribe any of the above lenses for frequent / planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear, the lens may be disinfected using a chemical disinfecting system.
HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens is a spherical lens. It is fabricated from polymacon which has been adopted by the United Stated Adopted Names Council (USAN). The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution.
The lens material, polymacon, is a hydrophilic polymer of 2-hydroxyethyl methacrylate (HEMA) cross-linked with ethylene glycol dimethacrylate (EGDMA), initiated by 2, 2'-azobisisobutyronitrile (AIBN). The lens consists of 62% polymacon and 38% water by weight when immersed in standard saline solution.
HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens is available cosmetic tinted to enhance or alter the apparent color of the eye. It is tinted in an annular pattern, providing a clear optic zone, using a combination of one or more of the following 'listed' color additives: Reactive black 5, Titanium dioxide, Iron oxides, Solvent Yellow 18, Carbazole violet, Pigment Blue 36, Phthalocyanine green.
The proposed color lenses are manufactured by sandwiching the pattern layer containing color additives between two layers of lens materials (polymacon).
In the hydrated state, HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens conforms to the curvature of the eye covering the cornea and extending slightly beyond the limbus, and it acts as a refracting media to focus light rays on the retina.
HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens is available in the spherical configuration with the following features and properties: Back vertex power -10.00D to 0.00D, step: 0.25D; Base curve 8.40 mm to 8.70 mm, step: 0.10 mm; Total diameter 13.80 mm to 14.50 mm, step:0.10 mm.
The physical properties of the proposed lens are: Specific gravity 1.124; Refractive index 1.437; Light Transmission 93% ± 5%; Surface character Hydrophilic; Water content 38%; Oxygen permeability 8.99x10^-11 (cm²/s) [ml O₂/(ml·mmHg)] at 35°C.
HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens is supplied sterile in the foil blister pack containing the borate buffer solution.
The provided document is a 510(k) Premarket Notification for a contact lens, the HPM38 (polymacon) Daily Wear Soft (hydrophilic) Contact Lens. It details the device's characteristics, its comparison to a legally marketed predicate device, and the non-clinical tests performed to demonstrate its safety and effectiveness.
Based on the provided text, no information on a study proving the device meets acceptance criteria for an AI/ML powered device, specifically in the context of human-in-the-loop performance, standalone algorithm performance, or ground truth establishment by experts, is present.
The document specifically states in Section 8: "This 510(k) submission does not utilize clinical study for establishing substantial equivalence therefore this section does not apply." This confirms that there was no clinical study, let alone one involving AI or expert human readers, to assess and prove the device meets acceptance criteria as envisioned in the prompt's requirements.
The "acceptance criteria" discussed in this document are related to the physical, chemical, optical, and biological safety and performance of the contact lens itself, not an AI/ML algorithm.
Therefore, I cannot provide the requested information for acceptance criteria and a study proving the device meets acceptance criteria within an AI/ML context because the document is a 510(k) premarket notification for a contact lens and does not describe such a study.
However, I can extract the acceptance criteria and performance related to the contact lens itself from the document.
Acceptance Criteria and Reported Device Performance (Non-AI/ML Medical Device)
The document primarily focuses on demonstrating the substantial equivalence of the HPM38 contact lens to a predicate device (Neo Cosmo (polymacon) Soft (hydrophilic) Contact Lens, K142275) based on physical, optical, physicochemical, and biocompatibility properties. The "acceptance criteria" are implied by meeting the standards outlined in regulatory guidances and internationally recognized standards (e.g., ISO, ASTM).
1. A table of acceptance criteria and the reported device performance:
The document presents a comparison table (Section 6) and lists performance tests (Section 7). Below is a summary of the key physical and optical properties and their reported values, which implicitly serve as the device's performance against industry and regulatory expectations for these parameters. The "acceptance criteria" are generally that these parameters fall within acceptable ranges for contact lenses and demonstrate equivalence to the predicate device.

The Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens is a daily wear soft contact lens indicated for daily wear to enhance or alter the apparent color of the eye and/or for the correction of refractive ametropia (myopia and hyperopia) in phakic or non-aphakic persons with non-diseased eyes who exhibit refractive astigmatism of 1.00D or less where the astigmatism does not interfere with visual acuity.
Eye care practitioners may prescribe the lens for either single-use disposable wear, or for frequentl planned replacement wear, with cleaning, disinfection, and scheduled replacement. When prescribed for single-use disposable wear, the lens is to be discarded after each removal. therefore no cleaning or disinfecting is required. When prescribed for frequent replacement, the lens may be disinfected using a chemical disinfection system only.
The Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens is available in hemispherical flexible shells for myopia. The Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens is an aspherical design contact lens. The lens material (Polymacon) is a hydrophilic co-polymer by crosslinking 2-Hydroxyethyl methacrylate (HEMA). and Ethylene Glycol Dimethacrylate (EGDMA). The hydrated lens consists of 62.0% (Polymacon) and 38.0% water by weight of saline immersed in normal saline. A light blue color tinted with "reactive Blue 247" is for handling visibility purpose. A benzophenone UV absorbing monomer is used to block UV radiation. The average transmittance characteristics are less than 5% in the UVB range of 280 to 315nm and less than 50% in the UVA range of 315 to 380 nm. The lenses contain a combination of the following color additives: Phthalocyanine green, Carbazole violet, [Phthalocyaninato (2-)] copper, Titanium dioxide, Iron oxides (Red, Yellow and Black),and Mica-based pearlscent pigment (Gold, Silver and Red). All color additives used are listed in 21 CFR 73 subpart D and 74 subpart D. It is supplied in a sterile package with buffered saline solution.
This document describes the premarket notification (510(k)) clearance for the Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens. However, it does not contain information typically associated with acceptance criteria and a study that proves a device meets them in the context of an AI/ML medical device.
This type of FDA clearance (510(k)) is for a physical medical device (a contact lens) and relies on demonstrating substantial equivalence to a previously cleared predicate device, rather than a clinical study with quantifiable performance metrics against specific acceptance criteria for an algorithm.
Therefore, many of the requested elements for an AI/ML device (like sample size for test/training sets, ground truth establishment methods, expert qualifications, MRMC studies, or standalone performance) are not applicable or not provided in this document.
Here's the breakdown of what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance
The document provides a comparative table (Table 8) against predicate devices, focusing on physical and chemical characteristics. It does not present a formal "acceptance criteria" table with reported performance in the way one would for an AI/ML algorithm. Instead, it demonstrates similarity to predicate devices.
| Item | Acceptance Criteria (Implicit: Similar to Predicate) | Reported Device Performance (Largan U38 Color) |

Note on "Acceptance Criteria": For this type of device, the "acceptance criteria" effectively boil down to demonstrating that the device is as safe and effective as the predicate device(s) based on comparable technological characteristics and non-clinical and biocompatibility testing. The inclusion of color additives is a distinguishing feature, and the safety of these additives is addressed through biocompatibility testing and their listing in 21 CFR 73 subpart D and 74 subpart D.
2. Sample size used for the test set and the data provenance
Not applicable for this type of device (physical contact lens). The document describes non-clinical and biocompatibility tests, but not a "test set" for an algorithm.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable.
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
Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
Not applicable. The "ground truth" here is the established safety and effectiveness of the predicate device, against which the new device's physical, chemical, and biocompatibility properties are compared.
8. The sample size for the training set
Not applicable.
9. How the ground truth for the training set was established
Not applicable.
Summary of the Study Proving Acceptance:
The device's acceptance is based on demonstrating substantial equivalence to legally marketed predicate devices (Largan U38 (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens and Largan 55 UV Color (Ocufilcon D) Daily Wear Soft (hydrophilic) Contact Lens), as evidenced by:
- Identical Intended Use: Both the subject device and predicates are indicated for correction of refractive ametropia (myopia and hyperopia) in non-diseased eyes with limited astigmatism, for daily or frequent/planned replacement wear. The subject device adds the function of enhancing or altering eye color, which is already present in the secondary predicate (Largan 55 UV Color).
- Similar Technological Characteristics: The document provides a detailed comparison (Table 8) showing that the subject device shares many key physical and optical parameters (lens design, replacement schedule, chemical composition (with primary predicate), water content (with primary predicate), oxygen permeability (with primary predicate), base curve, diameter, center thickness, powers, refractive index (with primary predicate), light transmittance) with one or both predicate devices.
- Non-Clinical Testing: Various physical and optical properties were tested (Back Vertex Power, Radius of Curvature, Overall Diameter, Center Thickness, etc.) to ensure the device performs as expected.
- Biocompatibility Testing: Conducted in accordance with FDA guidance (Premarket Notification [510(k)] Guidance Document for Class II Daily Wear Contact Lenses (1994)), including:
- In-Vitro Cytotoxicity (non-cytotoxic)
- Ocular irritation testing (no ocular irritation)
- Acute systemic toxicity (no acute systemic toxicity)
- Skin Sensitization Study (no skin sensitization)
- Color Additives: The color additives used are listed in 21 CFR 73 subpart D and 74 subpart D, addressing the safety aspect of the color-enhancing feature.
The conclusion is that the "Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens" is as safe, as effective, and performs as well as the predicate devices, thereby meeting the criteria for 510(k) clearance based on substantial equivalence.
