The lenses are available in the following lens parameters: Base Curve, Center Thickness, Diameter, Spherical Power, Secondary Curves, Peripheral Curves, Multifocal Power.
The provided document is a 510(k) Premarket Notification for the iSee Daily Wear Orthokeratology Contact Lenses. It does not contain any information about acceptance criteria or a study proving the device meets acceptance criteria in the context of an AI/ML medical device.
Instead, the document focuses on demonstrating substantial equivalence to an already marketed predicate device (OPTIMUM GP OK Daily Wear Contact Lens). The basis for this equivalence is a comparison of technological characteristics, materials, production methods, and intended use.
Here's a breakdown of why this document doesn't provide the requested AI/ML device study information:
- Non-Clinical and Clinical Studies (Section VII): This section explicitly states:
- "The non-clinical performance data to establish the safety and effectiveness of contact lenses manufactured from roflufocon D and roflufocon E has been addressed by reference to the predicate devices."
- "Clinical performance data to demonstrate the safety and effectiveness of contact lenses manufactured from roflufocon D and roflufocon E have been addressed in previous applications."
This means that C&E GP Specialists, Inc. did not conduct new independent studies for this 510(k) submission. They are relying on existing data for the materials and the predicate device to establish safety and effectiveness.
Therefore, I cannot provide the requested information from this document for an AI/ML device since it is for a contact lens and references prior data rather than presenting a new study.

The provided text is a 510(k) summary for the OPTIMUM GP OK (Orthokeratology) Daily Wear Contact Lens. It does not describe a study that uses acceptance criteria in the manner typically associated with AI/ML device performance evaluations. The document focuses on demonstrating substantial equivalence to predicate devices for regulatory clearance, rather than presenting a detailed clinical or technical study with specific performance metrics and acceptance thresholds for a novel device function.
Therefore, many of the requested fields cannot be directly extracted or are not applicable from this type of regulatory document.
However, I can extract information related to product specifications and a comparison to predicate devices, which serve a similar purpose in demonstrating that the new device is "as good as" existing, cleared devices.
Here's an attempt to answer the questions based on the provided text, while noting where information is not available:
1. Table of Acceptance Criteria and Reported Device Performance
This document does not present "acceptance criteria" in the context of a statistical study with performance metrics (e.g., sensitivity, specificity, accuracy) for a new algorithm or diagnostic test. Instead, it demonstrates substantial equivalence by comparing the physical and chemical properties and indications for use of the proposed device to legally marketed predicate devices. The "performance" here is that its characteristics are similar enough to existing devices to not raise new questions of safety and effectiveness.
Here's a table comparing key characteristics of the subject device with its predicates, as presented in the document:

2. Sample Size Used for the Test Set and the Data Provenance
- Sample Size (Test Set): 138 eyes were initially enrolled, with 136 eyes dispensed contact lenses. 110 eyes completed a minimum of three months of contact lens wear. The performance data is generally reported on these 110 eyes that completed the study.
- Data Provenance: The document does not explicitly state the country of origin. It describes a "Preclinical Studies: Described in the original 510 (k) submission K941883" and "Clinical Studies" for the K9736097 submission, suggesting the data is part of the regulatory submission for the United States. The study appears to be prospective clinical trial, observing patients over a three-month period.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
The document does not provide information on the number or qualifications of experts used to establish a ground truth for the test set. Clinical studies concerning contact lenses typically rely on measurements taken by trained optometrists or ophthalmologists, but this information is not detailed here.
4. Adjudication Method for the Test Set
The document does not describe any specific adjudication method (e.g., 2+1, 3+1, none) for the test set data. Clinical measurements were likely taken by the participating clinicians.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This study is a clinical trial evaluating the safety and effectiveness of a medical device (contact lens) in patients, rather than an AI-assisted diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
No, a standalone (algorithm only) performance study was not done. This product is a physical medical device (contact lens), not an algorithm or AI system.
7. The Type of Ground Truth Used
The "ground truth" for evaluating the contact lens's performance was based on direct clinical measurements and observations of the patients using the device, including:
- Refractive Power: Measured reduction in myopic refractive error (diopters).
- Visual Acuity: Measured visual acuity (e.g., 20/20, 20/40).
- Keratometry: Measured changes in corneal flattening (diopters).
- Slit-Lamp Findings: Direct observation of ocular health.
- Adverse Events/Symptoms/Complaints: Patient reported and clinically observed adverse effects.
8. The Sample Size for the Training Set
This product is a physical medical device (contact lens), not an AI algorithm. Therefore, there is no "training set" in the context of machine learning. The clinical study enrolled 138 eyes, with 110 eyes completing three months of wear. This would be considered the sample for evaluating the device's performance.
9. How the Ground Truth for the Training Set Was Established
As this is not an AI algorithm, there is no "training set" or "ground truth" for a training set in the machine learning sense. The clinical data collected from the 110 eyes that completed the study served as the evidence for safety and effectiveness.
