AI/ML Overview

The provided text describes the 510(k) summary for the OPTIMUM GP Rigid Gas Permeable Contact Lens, but it does not contain information about an AI/ML device or a study proving its acceptance criteria in the context of an AI-powered medical device.

The document pertains to a physical medical device (contact lenses) and its safety and efficacy are demonstrated through preclinical testing (toxicology, packaging, shelf life, solution compatibility) and clinical testing on human subjects, rather than through an AI/ML model's performance metrics.

Therefore, I cannot fulfill the request to provide information based on your numbered criteria (1-9) as they are tailored for AI/ML device evaluations and are not applicable to the content provided. The document does not discuss acceptance criteria or studies related to AI performance, sample sizes for AI test/training sets, expert ground truth, adjudication methods, MRMC studies, or standalone algorithm performance.

If you have a document describing an AI/ML device, please provide that for analysis.

Description of Safety:

A series of preclinical testing were performed to demonstrate the safety and effectiveness of the OPTIMUM GP Rigid Gas Permeable Contact Lens material. The results of all testing demonstrated that Of TIMOM Of Trigit Ous I entreaste Coanable Contact Lens is equivalent Lens is equivalent to the the surely marketed predicate devices previously identified. A summary of these results from the preclinical studies is presented below.

Toxicology:

In-Vitro Cytotoxicity: ISO 10993-5 was conducted in accordance with standards on test article. The test article meets the requirements of the Agarose Overlay Method.

Systemic Toxicity: The lens material meets the requirements of the systemic injection test and is considered non-toxic.

Acute Ocular Irritation: Acute ocular irritation test was performed and produced no ocular irritation.

Packaging

The primary container for shipping the OPTIMUM GP Rigid Gas Permeable Contact Lenses is the Alcon Contact Lens Case, with clearance under 510(k) K974281. The lens is shipped (wet) non-sterile in the OPTIMUM by Lobob Cleaning and Disinfecting Storage solution, with clearance under 510(k) 014162. The solution contains lauryl sulfate salt of imidazoline, octylphenoxy polyethoxyethanol and preserved with benzyl alcohol.

Shelf Life

The OPTIMUM GP Rigid Gas Permeable lens is a hydrophobic contact lens material with <1% water content. When the OPTIMUM GP lenses are shipped dry, shelf life studies are not required for clearance of this material.

When the OPTIMUM GP lenses are shipped wet, shelf life studies are required for clearance of this material. See following Bioburden Testing to Evaluate 30 -Day Storage (Shelf Life) in a Cleaning, Disinfecting and Storage GP Solution:

Contamac performed stability, compatibility and microbiology testing on OPTIMUM GP Contact Lenses wet shipped in OPTIMUM by Lobob GP Cleaning, Disinfecting and Storage Solution and stored for up to 30 days. This testing combined with utilization of the contact lens container identified supports the claim of substantial equivalence to Boston RGP lenses wet shipped and stored for up to 30 days.

{5}------------------------------------------------

Stability/Compatibility ~ The Fluorosilicone acrylate OPTIMUM GP Rigid Gas Permeable Contact Lenses were subjected to a thirty-day soak in OPTIMUM by Lobob GP Cleaning, Disinfecting and Lensts were subjected to a the lens compatibility protocol. The average changes for each parameter (diameter, base curve and power), relative to the initial measurements were determined. (thanceer, base our o ma porter), reases at room temperature for thirty days the OPTIMUM GP rigid gas permeable contact lenses were determined to be physically compatible with OPTIMUM by Lobob GP solutions.

Microbiology ~ A bioburden study was completed. A set of test lenses was cleaned with OPTIMUM by Lobob Extra Strength Cleaner for rigid gas permeable lenses and subjected to bioburden testing. In this Looo Extra Successive Included the storage in OPTIMUM by Lobob GP Cleaning, Disinfecting and ttos, tenses were to vanued that the colony forming units (CFU) per lens was less than 2. The acceptance criteria is 100 CFU per lens.

Solution Compatibility

Studies were conducted on blue tinted lens material. Lenses were run through 30 cycles of cleaning and conditioning to establish the compatibility of the lens material with the recommended care regimen. The parameters of the base curve, back vertex power, total diameter and overall lens physical appearance were pannievers of the oal ver re, resultive of 30 cycles. Initial and final data were compared. There were no significant changes to lens parameters after 30 complete cycles.

Clinical Testing

Below is a summary of the clinical study carried out to evaluate the safety and efficacy of the OPTIMUM GP Rigid Gas Permeable Contact Lens material when used as a daily wear contact lens for the correction of visual acuity.

A total of 272 eyes (136 patients) were entered into the study by 10 investigators. Prior to entry into this study each patient was required to read and sign a statement of informed consent. All patients who signed a Statement of Informed Consent are accounted for in this report. Of the 272 eyes (136 patients enrolled), 246 eyes (123 patients) completed the study.

The safety and efficacy measures for the study were:

Safety: Adverse Events, Positive Slit Lamp Findings, Symptoms/Complaints and Keratometry Changes.

Efficacy: Refractive Changes, Lens Visual Acuity, Lens VA Line Changes, Comfort and Vision, Average Wearing time.

The sponsor concludes that OPTIMUM Rigid Gas Permeable Contact Lens material is equivalent in safety and efficacy to the predicate devices.
