The provided document is a 510(k) Summary for the Bausch + Lomb Stellaris Elite™ vision enhancement system. It primarily focuses on demonstrating substantial equivalence to a predicate device after software and hardware updates, rather than presenting a study proving a device meets specific acceptance criteria for performance.

Therefore, many of the requested categories cannot be fully addressed in the traditional sense of a clinical or performance study aimed at defining and meeting specific analytical or clinical performance metrics. The document describes how substantial equivalence was demonstrated, which involves various types of testing, but not a study designed to prove new performance claims against defined acceptance criteria.

Below is the information extracted and interpreted based on the context of this 510(k) submission, highlighting what is available and what is not.

Acceptance Criteria and Device Performance Study for K232084

This 510(k) submission (K232084) is for updates to the Bausch + Lomb Stellaris Elite™ vision enhancement system, not for a new device making novel performance claims. The primary goal is to demonstrate "substantial equivalence" to a legally marketed predicate device (K170052 Stellaris Elite™ vision enhancement system) after changes to the User Interface Computer System on Module (SOM) and an update to the operating system from Windows XP to Windows 10. Consequently, the "acceptance criteria" and "device performance" are framed in terms of meeting regulatory standards and maintaining performance equivalent to the predicate device, rather than achieving specific performance thresholds for a novel diagnostic or therapeutic claim.

1. A table of acceptance criteria and the reported device performance

Given the nature of this 510(k) for system updates, the "acceptance criteria" are regulatory compliance and maintained functionality, rather than specific numerical performance metrics for a clinical task.

2. Sample size used for the test set and the data provenance
The document does not specify a "sample size" in the context of a dataset for AI or clinical study. Instead, it refers to "representative units" for hardware testing (electrical safety, EMC) and software verification/validation.

• Test Set Sample Size: Not applicable in the context of an AI-driven clinical test set. Testing was performed on the device itself and its software.
• Data Provenance: Not applicable as no patient data or image data was used for a test set. This submission is for hardware/software updates to an ophthalmic surgical system. The standards cited (IEC standards for electrical safety, EMC, software lifecycle) are international regulatory standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. No "ground truth" for a test set (e.g., diagnostic labels, disease states) was established by experts in this submission, as it's not a diagnostic AI device.

4. Adjudication method for the test set
Not applicable. There was no test set requiring expert adjudication.

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-assisted diagnostic or interpretation device that would involve human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is an ophthalmic surgical system, not a standalone algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
Not applicable in the context of a clinical performance study. For software and hardware validation, the "ground truth" would be the functional requirements and established performance specifications of the predicate device and relevant international standards.

8. The sample size for the training set
Not applicable. This device does not use a "training set" in the sense of machine learning for interpretation or diagnosis.

9. How the ground truth for the training set was established
Not applicable.

STELLAR Knee is a stereotaxic system including an intraoperative software as a medical device and surgical instruments. STELLAR Knee is indicated for primary Total Knee Replacement, to assist the surgeon in determining reference alignment axes in relation to anatomical landmarks, in order to position the cutting guide regarding computed mechanical axis. The STELLAR Knee is installed on a Head Mounted Device (HMD) for displaying information to the user intraoperatively. The HMD should not be relied upon solely and should always be used in conjunction with traditional methods.

The main purpose of the STELLAR Knee is to assist the surgeon during the primary Total Knee Replacement (TKR) intervention. STELLAR Knee includes software and surgical instruments.

STELLAR Knee uses established surgical navigation techniques to provide information to help track patient bony landmarks in real time to assist the surgeon in determining resection angles and measurements as required in knee replacement surgery. STELLAR Knee allows the surgeon to adjust the cutting plane orientation and the resection level. This includes means for the surgeon to collect anatomical references during the TKR intervention using the surgical instruments. The software locates in a 3D reference frame the instruments which include marker arrays. All collected coordinates are treated by software algorithms to provide the surgeon with the relevant orientation of the tracked cutting quide. STELLAR Knee software is installed on a wearable Head Mounted Device (HMD) which includes an embedded camera and displays intraoperative information to the user. This near-eye display allows the surgeon to look at the HMD screen or the field of view when needed.

The provided text describes a 510(k) premarket notification for the STELLAR Knee device, which is a stereotaxic system for Total Knee Replacement. However, the document does not contain the detailed acceptance criteria or the study data that proves the device meets those criteria.

The "Non-clinical performance testing" section briefly mentions that "Bench testing was conducted in order to demonstrate that STELLAR Knee performs according to its requirements and specifications when installed on the Head Mounted Device. In particular, overall system repeatability and accuracy were tested." It also states, "The results demonstrated that the STELLAR Knee performs according to its specifications and functions as intended."

However, information regarding specific quantitative acceptance criteria (e.g., accuracy thresholds in mm or degrees), the reported device performance against these criteria, sample sizes used, data provenance, ground truth establishment, or any comparative effectiveness studies (MRMC) is not provided in this document.

Therefore, I cannot fulfill the request to provide a table of acceptance criteria and reported device performance, nor the details of any study that proves the device meets specific acceptance criteria based on the given input. The document focuses on establishing substantial equivalence with a predicate device based on similar indications for use, operating principles, and general performance testing, without detailing the results of those performance tests in a quantitative manner against predefined acceptance criteria.

In addition to the functions of Panoramic, Stellaris 2D Ceph also allows to perform One-Shot Cephalometric radiographs.

Except for the panoramic acquisition sensor, the remaining mechanical, electrical and software characteristics of Stellaris 2D are exactly identical to those of Stellaris 3D.

The control panel interface on the unit provides a complete control of the operation and for the setting of the desired technique factors.

Class I LASER aiming lights support positioning of patient's head, which is stabilized through the use of bite blocks, chin rest, and, if required, temple supports.

The user controls the exposure using a manual hand-switch, implementing the dead man functionality.

An Ethernet connection cable allows the FONA Stellaris devices to interface with a computer for image acquisition, processing and storage.

The provided document is a 510(k) Premarket Notification from FONA S.r.l. to the FDA for their Stellaris dental X-ray systems. It primarily focuses on demonstrating substantial equivalence to predicate devices based on technical specifications and adherence to relevant standards.

The document does NOT describe the acceptance criteria for an AI/ML powered device, nor does it detail a study proving such a device meets acceptance criteria.

The Stellaris devices are dental X-ray systems (2D and 3D, with and without cephalometric capabilities). The document explicitly states:

• "The Stellaris 2D, Stellaris 2D Ceph, Stellaris 3D, Stellaris 3D Ceph devices can be used with the OrisWin DG Suite software for image acquisition and database (not part of this submission)..." (page 8)
• "...the 3D sensor has been replaced with a 2D sensor." (page 10)
• "The principle of operation of the Stellaris 2D, Stellaris 2D Ceph, Stellaris 3D, Stellaris 3D Ceph devices remains the same as the predicates. The difference is the type of sensors used which work on similar principles as the sensors found in the predicate devices." (page 7)

There is no mention of any AI or machine learning components within the device itself for diagnostic or image processing purposes that would require specific performance criteria or a study as outlined in the request. The "reconstruction algorithm" mentioned is standard for CT and panoramic imaging, not an AI/ML algorithm requiring separate clinical performance validation from the device's image acquisition capabilities.

Therefore, I cannot extract the requested information as it is not present in the provided text. The document describes a traditional 510(k) submission for an imaging device, demonstrating substantial equivalence through technical characteristics, safety standards (IEC, EN), software standards (EN 62304), and biocompatibility (ISO 10993-1).

In summary, none of the requested information regarding AI/ML acceptance criteria or a comparative study proving device performance against such criteria can be found in this document.

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the Stellaris Elite Vision Enhancement System are based on compliance with various international electrical and medical device standards, and successful functional, simulated use, environmental, and transport testing. The reported device performance is that it met all these criteria.

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

The document does not specify a "test set" in terms of patient data or
clinical cases. The testing conducted was primarily hardware and software performance verification. The non-clinical tests involved "representative units" of the device. There is no information regarding country of origin of data or whether it was retrospective or prospective, as the testing described is not clinical in nature.

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

This information is not applicable. The listed tests are engineering and compliance standards, not clinical studies requiring expert ground truth establishment for patient data. Expert involvement would be in the form of engineers, quality assurance personnel, and regulatory specialists ensuring compliance with the standards.

4. Adjudication Method for the Test Set

This information is not applicable. Adjudication methods are typically used in clinical studies when there's uncertainty about ground truth or disagreement among readers (e.g., radiologists). The testing described here is based on objective measurements against engineering and safety standards.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No, an MRMC comparative effectiveness study was not done. The submission focuses on demonstrating substantial equivalence through technical characteristics and compliance with standards, not on comparing human reader performance with and without AI assistance. This device is not an AI-powered diagnostic tool, but a surgical system.

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

This concept is not directly applicable to the Stellaris Elite Vision Enhancement System. As a surgical system, it is inherently designed for human-in-the-loop operation. The "standalone" performance being assessed relates to the system's compliance with engineering and safety standards as an independent medical device, not as an algorithm performing a task without human intervention. The software verification and validation would be considered "standalone" in the sense of the software itself being tested, but in the context of contributing to the overall device's safety and functionality.

7. The Type of Ground Truth Used

The "ground truth" for the device's performance is established by its adherence and successful execution to various international engineering and medical device safety standards (e.g., IEC 60601 series, EN ISO IEC 62304). These standards define the acceptable performance, safety, and operational parameters for such medical equipment.

8. The Sample Size for the Training Set

This information is not applicable. This document describes a medical device, not an AI model that relies on training sets of data. The software within the device undergoes verification and validation, but this is distinct from machine learning model training.

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

This information is not applicable as there is no mention of a "training set" for an AI model in the context of this device's submission.
