The provided text is a 510(k) Premarket Notification from the FDA for a medical device (Rigid Gas Permeable Contact Lenses). It is not a study proving the device meets acceptance criteria for an AI/Software as a Medical Device (SaMD) product.
Therefore, I cannot extract the requested information about acceptance criteria, study sizes, expert ground truth establishment, MRMC studies, or training sets, as these concepts are not applicable to the type of device and submission described in the provided document. The document primarily focuses on establishing substantial equivalence to previously cleared predicate devices for contact lenses based on material properties, manufacturing methods, and intended use.
The "PERFORMANCE DATA VII." section specifically mentions "Non-Clinical Studies" and "Clinical Studies". However, these sections refer to studies that were "addressed through previously cleared 510(k) premarket notifications" for the materials and existing uses of the contact lenses, rather than a new study demonstrating the performance of an AI-powered device.
If you have a document describing an AI/SaMD study, I would be happy to analyze it for the criteria you've outlined.

The provided text describes the acceptance criteria and study proving the performance of the Acuity 200™ (fluoroxyfocon A) Rigid Gas Permeable Contact Lens.
Here's an analysis of the requested information:
1. Table of acceptance criteria and the reported device performance:
The document doesn't explicitly state quantitative acceptance criteria in a table format that would typically be seen for an AI device (e.g., target accuracy, sensitivity, specificity thresholds). Instead, the study aims to demonstrate substantial equivalence to a predicate device (Acuity 100). The "acceptance criteria" are implied by the comparison to the predicate device in terms of safety and effectiveness endpoints.
Metric / Endpoint | Acceptance Criteria (Implicit for Substantial Equivalence to Acuity 100) | Reported Device Performance (Acuity 200™) |
---|---|---|
Effectiveness - Visual Acuity | Substantially equivalent to Control lenses (Acuity 100) | Test and control lenses performed similarly with respect to contact lens corrected visual acuity results. |
Safety - Objective Findings (Slit lamp: staining, edema, vascularization, hyperemia, infiltrates, other complications) | No severity worse than Grade 2 (except for isolated instances permitted in predicate) | None of the completed or discontinued eyes in the test arm reported a severity worse than Grade 2 for these findings. |
Safety - Subjective Symptoms (Discomfort, Dryness, Irritation) | Incidence and severity similar to Control lenses (Acuity 100) | Test and control lenses performed similarly with respect to subject reported symptoms. Symptoms reported with highest frequency (discomfort, dryness, irritation) showed no clinical difference in incidence between test and control arms. |
Safety - Adverse Events | Incidence and severity similar to Control lenses (Acuity 100) | Adverse events that occurred in the study were similar in both arms, in terms of incidence and severity. |
Safety - Vision Safety Measures (Keratometry changes, Refractive changes, Best corrected visual acuity) | No clinically relevant differences or negative trends compared to Control lenses (Acuity 100) | The test and control lenses performed equally well with regards to vision safety measures. Trend analysis shows no emerging trends for test and control lenses for the duration of the study. |
Biocompatibility | Meets ISO 10993-1:2018 standards for biological evaluation. | Evaluation conducted according to ISO 10993-1:2018. Tests performed include Cytotoxicity, Systemic Toxicity, Ocular Irritation, and Skin Sensitization. Device found to show biocompatibility for a surface device, limited contact. |
Performance Testing (Lens/solution compatibility, Manufacturing verification, Extractable testing, Contact angle, Dry shelf life, Lens stability testing) | Meets required performance standards for safety and intended function. | These tests were performed to establish the performance of the device. The non-clinical data demonstrates the safety of the device and demonstrates that the device should perform as intended. |
2. Sample size used for the test set and the data provenance:
- Test Set Sample Size: 74 subjects (148 eyes) were enrolled.
- 50 subjects (100 eyes) were in the test group (Acuity 200™).
- 24 subjects (48 eyes) were in the control group (Acuity 100).
- 58 subjects completed the scheduled visits (40 in test group, 18 in control group).
- Data Provenance:
- Country of origin: United States. Subjects were evaluated at four independent clinical sites across the United States.
- Retrospective or Prospective: Prospective. The study design is described as an "open-label, multi-center, randomized concurrent-control study with the treatment duration of 90 days."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This document describes a clinical study for a contact lens, not an AI/ML device relying on expert-annotated ground truth for image analysis. Therefore, the concept of "experts used to establish ground truth" in the AI sense (e.g., radiologists marking images) does not directly apply here.
The "ground truth" for this study is derived from:
- Objective clinical measurements: Slit lamp observations (staining, edema, vascularization, hyperemia, infiltrates), keratometry, refractive changes, best corrected visual acuity, adverse event reporting. These are direct measurements/observations by licensed healthcare professionals at the clinical sites.
- Subjective patient reporting: Symptoms (discomfort, dryness, irritation), problems, and complaints.
The qualifications of the clinicians performing these assessments are not explicitly stated beyond them being affiliated with "four independent clinical sites."
4. Adjudication method for the test set:
Not applicable in the typical AI/ML context of image interpretation. The study is a clinical trial with observational and measurement endpoints. Data was collected by clinicians at study sites. There's no mention of an independent adjudication panel reviewing discrepancies in diagnoses or measurements in the way one would for an AI ground truth dataset.
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. This is a clinical trial for a physical medical device (contact lens), not an AI-assisted diagnostic tool. Therefore, MRMC studies and human reader improvement with AI assistance are irrelevant to this submission.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical medical device; there is no "algorithm only" performance.
7. The type of ground truth used:
As explained in point 3, the "ground truth" for this clinical study consists of:
- Objective Clinical Findings: Slit lamp observations, keratometry, refractive changes, visual acuity measurements.
- Subjective Patient Outcomes/Symptoms: Self-reported discomfort, dryness, irritation, problems, and complaints.
- Adverse Event Data: Documented adverse events.
This is fundamentally an outcomes data and expert clinical observation driven ground truth, rather than pathology or image-based consensus in an AI context.
8. The sample size for the training set:
Not applicable. This is a physical medical device. There is no "training set" in the context of machine learning model development. The "training" for such a device would refer to its manufacturing process development and quality control, which is implied by the non-clinical performance testing.
9. How the ground truth for the training set was established:
Not applicable, as there is no machine learning training set in this submission. The non-clinical performance data (biocompatibility, lens/solution compatibility, manufacturing verification, extractable testing, contact angle, dry shelf life, lens stability testing) are established through standard laboratory and manufacturing evaluation processes.

The Acuity 100 (hexafocon A), Acuity 85 (oprifocon A), Acuity 58 (enflufocon B) and Acuity 18 (enflufocon A) Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, hyperopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D to +20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lens may be disinfected using a chemical disinfection system only. The lenses may be stored in a multipurpose solution (BOSTON SIMPLUS or Menicon Unique pH) solution up to 30 days.
The Acuity Polymers Rigid Gas Permeable Contact Lenses are daily wear rigid gas permeable contact lenses comprised of fluoro-silicon acrylate copolymers wet shipped in Boston SIMPLUS Multi-Action Solution or Menicon Unique pH Multi-purpose solution.
The provided text describes the regulatory clearance of "The Acuity 100 (hexafocon A), Acuity 85 (oprifocon A), Acuity 58 (enflufocon B) and Acuity 18 (enflufocon A) Rigid Gas Permeable Contact Lenses." However, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with specific acceptance criteria and results.
Therefore, the requested information regarding acceptance criteria, reported device performance, sample sizes, ground truth establishment, expert qualifications, adjudication methods, multi-reader multi-case studies, or standalone performance studies is not found in the provided document.
The document explicitly states: "Clinical data is not necessary as the products, both RGP lenses and multi-purpose disinfection solutions are cleared for use as indicated."
Instead, the submission relies on:
- Substantial Equivalence: The primary method for demonstrating safety and effectiveness is by showing that the new device is substantially equivalent to a legally marketed predicate device (BOSTON RGP Lenses Wet Shipped in Boston SIMPLUS Multi-Action Solution, K073184).
- Prior Clearances for Materials and Solutions: The gas permeable lens materials themselves (Acuity 100, Acuity 18, Acuity 85, Acuity 58) were previously cleared under separate 510(k)s. The multi-action solutions (BOSTON SIMPLUS and Menicon Unique pH) were also previously cleared. The current submission bundles these cleared components.
- Biocompatibility Testing: The materials have been tested and found to meet biocompatibility requirements listed in the FDA Daily Wear Contact Lens Guidance Document, May 1994, and ISO 10993-1 (2009).
- Solution Compatibility Studies: Previous 510(k)s for the individual RGP lens materials included solution compatibility studies demonstrating stable lens parameters when using the specified solutions.
- Microbiological Methods (Bioburden Studies): Bioburden studies (in accordance with ISO 11737-1) were conducted to monitor lens manufacturing. These were extended to evaluate wet storage and shipping for up to 30 days, finding "no CFUs were found at any test point during the 30-day period." This represents a specific "performance" aspect, but not in the context of clinical efficacy.
- Conformance to Standards: The quality system conforms to ISO Standard 13485 (2003).
In summary, the document argues that the device meets regulatory requirements by demonstrating substantial equivalence to a predicate device and by referencing prior clearances and standard-based testing for its constituent materials and solutions, rather than presenting a new, dedicated study with specific performance acceptance criteria.
