The UBM Plus is designed for imaging the internal structure of the eye including opaque media and anterior segment pathology, for the purpose of diagnosing pathological or traumatic conditions in the eye.

Device Description

The UBM Plus device is designed as a high frequency ultrasound B-Scan, which uses pulsed echo ultrasound to image the anterior segment of the eye. It utilizes a noncontact probe via a contact Scleral shell to generate and receive the ultrasound pulses, and provides a graphic display of returning pulse echoes to indicate the various structures.

AI/ML Overview

The UBM Plus device's performance data and acceptance criteria are outlined in the provided text.

1. Table of Acceptance Criteria and Reported Device Performance:

	Acceptance Criteria (Stated as "acceptable limits")	Reported Device Performance
Line	<1% (implied to be within acceptable limits)	<1% (30mm)
Area	<1% (implied to be within acceptable limits)	<1% (30mm)
Angle	<1% (implied to be within acceptable limits)	<1% (30mm)

The document states that the accuracy of the UBM Plus is "less than 1%, well within acceptable limits," which allows for the inference of "<1%" as both the acceptance criteria and the reported performance. The "30mm" for each category appears to indicate the range over which the accuracy was tested.

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

The document mentions "Accuracy Testing (using a Gammex Lesion Phantom and a proprietary measurement phantom)".

Sample Size: The specific sample size (number of measurements or phantoms) for the accuracy testing is not explicitly stated.
Data Provenance: The testing was conducted using phantoms, which are artificial devices designed to simulate biological tissue properties for testing purposes. Therefore, the data is from non-clinical phantom testing, not from human subjects. The country of origin for this testing is not specified but is presumably where Accutome, Inc. (Malvern, PA, USA) or its associated testing facilities operate.

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

Ground truth for phantom testing is typically established by the inherent design and known physical properties of the phantom itself, rather than by human experts interpreting clinical images. The document does not mention any experts being used to establish ground truth for the phantom testing.

4. Adjudication Method for the Test Set:

Not applicable, as ground truth was established by the known properties of the phantoms, not through human interpretation requiring adjudication.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document states that "Since the UBM Plus uses the same technology as existing devices, clinical tests are not required." This implies that no human reader studies, assisted or unassisted, were performed for this 510(k) submission.

6. Standalone (Algorithm Only) Performance:

The "Accuracy Testing" using phantoms represents the standalone performance of the device in terms of its ability to accurately measure lines, areas, and angles. The results (<1% accuracy) are provided, indicating how well the device, on its own (without human interpretation directly affecting the measurement, beyond operating the device), performs these functions.

7. Type of Ground Truth Used:

The ground truth used for the accuracy testing was based on the known physical dimensions and properties of a Gammex Lesion Phantom and a proprietary measurement phantom.

8. Sample Size for the Training Set:

The document does not mention a training set for an algorithm. The UBM Plus is described as an ultrasound imaging system that provides measurements, not an AI or machine learning algorithm that requires a training set.

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

Not applicable, as there is no mention of a training set or an AI/machine learning algorithm requiring one.

Indications for Use:

Comparison of Technological Characteristics:

The instrument is used for the imaging of the internal structure of the eye including opaque media and anterior segment pathology for the purpose of diagnosing pathological or traumatic conditions of the eye.

The UBM Plus and B-Scan Plus are similar devices in that they are both ultrasonic B-Scans used to image the eye. The UBM Plus has an open tip design with an ultrasonic crystal that resonates at a frequency of 48 MHz, while the B-Scan Plus uses a closed tip design with a single crystal resonating at frequencies of 12 MHZ and 15 MHz. The open tip design of the UBM Plus requires the use of a Scleral Immersion Shell to capture measurements, while the closed tip design of the B-Scan Plus allows for direct contact between the probe and patient without potential injury. The UBM Plus range is fixed at 30mm, while the B-Scan Plus ranges are adjustable with ranges of 30, 50, 60 and 100mm. The UBM Plus runs using an updated software version of the B-Scan Plus. The UBM Plus offers the user the functionality of pan, zoom, annotation, A-Vector, distance/area/angle measurements, 256 grey scale levels, image annotation and gain controls. All of the listed functions are available on the B-Scan Plus, except angle measurements.

The UBM Plus and OTI-Scan 3000 are similar in that they both ultrasonic B-Scans utilizing high frequency probes. The UBM Plus utilizes a frequency of 48 MHz, while the OTI-Scan 3000 utilizes multiple probes with frequencies of 35 MHz and 50 MHz. Both the UBM Plus OTI-Scan 3000 use an open tip design and therefore both require the use of an Immersion Scleral Shell to capture measurements. This is referred to as an immersion cup in the OTI User Manual. The UBM Plus offers the user the functionality of pan, zoom, annotation, A-Vector, distance/area/angle measurements, 256 grey scale levels,
