Adjustable Chandelier Illuminator family of ophthalmic illuminators is for wide angle illumination during ophthalmic surgery.

The 23ga and 25ga Adjustable Chandelier Illuminators are made to work with the Bausch and Lomb surgical system and Bausch and Lomb Valved ESA (Entry Site Alignment) systems (K012435). These devices are to be manufactured with distally located "Infusion Cannulas" that adequately secure themselves within 23ga and 25ga Bausch and Lomb Valved ESA Systems. The 23ga and 25ga Adjustable Chandelier Illuminators consist of a PMMA (Polymethylm-ethacrylate with Flourinated Polymer Cladding) acrylic fiber (for light transmission), white acetal handle assembly with finger slide for adjustability, PTFE (Polytetrafluor-oethylene) jacket (for fiber) and Stellaris style light connector to fit into the Bausch and Lomb Stellaris PC Vision Enhancement System (K133486). The 23ga and 25ga Adjustable Chandelier Illuminators are to be provided sterile to the user, is a single-use device and is packaged in double Tyvek-to-poly pouches to facilitate introduction to the sterile environment. These provide illumination for eye surgery.

This document describes the premarket notification (510(k)) for the Peregrine 23ga and 25ga Adjustable Chandelier Illuminator. The purpose of this notification is to demonstrate that the device is substantially equivalent to legally marketed predicate devices.

Here's an analysis of the acceptance criteria and study information provided:

1. Table of Acceptance Criteria and Reported Device Performance

The document lists various non-clinical performance tests conducted to evaluate the device. The reported performance is that all results were "acceptable" and the device "satisfactorily met the requirements." Specific numerical acceptance criteria or performance metrics are not provided in this summary.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the numerical sample size for individual tests. However, it indicates that "Biocompatibility and sterility testing has been conducted on the 25ga Adjustable Chandelier Illuminators as a 'worst case device' and a family representative." This suggests a limited sample size, focusing on one representative (25ga).

The data provenance is internal, originating from Peregrine Surgical Ltd. It is retrospective, as these are bench tests conducted to support a premarket submission. No information about the country of origin of the data is provided beyond the company's location (New Britain, PA, USA).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. This device is not an AI/ML diagnostic or prognostic tool that requires expert-established ground truth on a test set. The tests performed are bench tests evaluating physical and functional characteristics of a medical illuminator. The "ground truth" for these tests would be the established standards and specifications outlined in the referenced ISO and ASTM methods, or the company's internal test protocol specifications.

4. Adjudication Method for the Test Set

Not applicable, as this is not a diagnostic assessment requiring adjudication among experts. The tests are objective measurements against defined standards.

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 not an AI/ML device, and no MRMC study was performed.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an AI/ML device. The "standalone" performance refers to the device's functional characteristics as an illuminator, which were assessed through the listed bench tests.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the non-clinical performance data is the defined acceptance criteria and specifications within the referenced ISO, ASTM, and Internal Test Methods. For example:

• Sterility: The device must meet the sterility assurance level (SAL) specified in ISO 11135-1.
• Biocompatibility: The device materials must meet the biological safety requirements outlined in ISO 10993-01.
• Light Output: The device's light output must meet the specified lumen value (3.7 lumen, as indicated in Table 5.2).

8. The Sample Size for the Training Set

Not applicable. This is a conventional medical device, not an AI/ML device that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. No training set was used.
