Intended Use

The ANTERION is a non-contact ophthalmic imaging and analysis device for the eye. It is intended for visualization of the anterior segment.

Device Description

The ANTERION is a diagnostic imaging device for the eye. The technology is based on swept-source optical coherence tomography (SS-OCT) technology. The device itself has two basic component groups:

  • . ANTERION Hardware (Imager/Basis) with integrated forehead/ chin rest: The hardware includes imaging hardware (e.g., laser, LEDs, optics, detectors, hardware for spatial encoding) as well as a touch screen.
  • ANTERION Software (PC): The ANTERION Software includes the main user . interface. The software allows for device control, such as selection of examination(s) and imaging parameter(s). The PC software additionally stores, receives, and displays the acquired data.

The ANTERION hardware is separated in three parts: the Basis (bottom part), the Imager (top part), and the Head Rest (forehead/chin rest).

For examinations, the patient places his/her head in the forehead/chin rest. The Head Rest is mechanically and electronically connected to the Basis and controlled via a ioystick. Placed within the stand are a stepper motor with additional mechanical parts and a controller board, allowing the operator to move the motorized chin rest up or down for optimally positioning the patients' eye. An external fixation light is mounted at the forehead rest.

The Basis mainly contains the power supply and PC connection of the device. In the Imager, the components for scanning, signal generation, and signal processing are contained.

The operator directly accesses two software modules, which are named AQM (acquisition module) and VWM (viewing module). The AQM allows selecting between examinations. The VWM shows acquired images, parameters, and reports.

The ANTERION device contains two imaging modalities, a scanning optical coherence tomography (OCT) modality and an infrared (IR) camera. The OCT modality allows for cross-sectional imaging, while the IR camera allows for en-face imaging of a patient's eye.

The Imaging App, the subject of this submission, is the foundation of the ANTERION platform, and focuses on the high-resolution visualization of the entire anterior segment, from the anterior surface of the cornea to the posterior surface of the lens.

The Imaging App delivers swept-source OCT images that allow visualization of anterior segment pathologies and evidence of surgical interventions, e.g. keratoplasty, LASIK, implanted IOLs, and phakic lenses.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study details for the ANTERION device, based on the provided text:

Acceptance Criteria and Device Performance

The provided document focuses on establishing substantial equivalence rather than explicit quantitative acceptance criteria with pass/fail thresholds. However, the study aims to demonstrate that the ANTERION's performance is similar to or better than the predicate and reference devices in key areas.

Here's a table summarizing the implicit acceptance criteria (demonstrated similarity or superiority) and the reported device performance:

Acceptance Criteria (Implied)Reported Device Performance
1. Image Quality of Anterior Segment StructuresOverall, the ANTERION shows superiority in image quality compared to each of the three CIRRUS scans. Specifics shown in Figure 1 indicate a higher percentage of "Good" image quality ratings for ANTERION across all evaluated structures (Cornea/Conjunctiva, Anterior Lens Surface, Iris, Angle, Scleral Spur) compared to CIRRUS scan types (CCN, CAC, CAG). For example, for Cornea/Conjunctiva, ANT showed 83.3% "Good" vs. 52.6% for CCN. This demonstrates ANTERION is at least similar to, and often superior, in image quality.
2. Ability to Identify Abnormality in Anterior Segment (compared to slit lamp reference)Overall, the ANTERION shows superiority compared to each of the three CIRRUS scans in identifying the abnormality in reference with the slit lamp examination. Figure 2 graphically represents this, showing higher percentages of "Match" (agreement with slit-lamp) for ANTERION (ANT) across various predefined abnormalities (e.g., cornea pterygium, corneal inlay, corneal transplant, trabeculectomy bleb, peripheral iridotomy, glaucoma drainage device) compared to CIRRUS scan types (CAC, CAG/CCN). This indicates ANTERION offers an equal or superior ability in identifying each pre-specified abnormality compared to CIRRUS.
3. Visualization of Key Anatomical StructuresThe ANTERION's ability to visualize key anatomical structures was similar to or better than CIRRUS. (This is a conclusion drawn from the image quality assessment where individual structures' visibility was graded).

Study Details:

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

    • Sample Size: 87 participants (34 in "Normal Anterior Segment group", 53 in "Abnormal Anterior Segment group"). One eye per subject was selected.
    • Data Provenance: Prospective, single clinical site in the United States.
  2. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications:

    • Number of Experts: Three independent graders were used for image quality and abnormality identification.
    • Qualifications: "Qualified graders" are mentioned. No specific experience (e.g., "radiologist with 10 years of experience") is provided, but they were described as "masked" and "independent."
  3. Adjudication Method for the Test Set:

    • Method: Majority rule was applied to get consensus from the three independent graders.
  4. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

    • Was it done? Yes, effectively. The study compared the ANTERION device to the CIRRUS HD-OCT 5000 device using multiple graders and multiple cases, assessing both image quality and abnormality identification.
    • Effect size of human readers improve with AI vs. without AI assistance: This study does not directly measure the improvement of human readers with AI assistance. Instead, it compares the device's performance (ANTERION) against a comparator device (CIRRUS) for diagnostic imaging purposes. Human graders (experts) were used to evaluate the output of both devices and establish ground truth, not to assess AI assistance to human readers.
  5. Standalone (Algorithm Only) Performance:

    • The study evaluates the ANTERION imaging app as a diagnostic device, which produces images and potentially analyses thereof. The assessment of image quality and abnormality identification was performed by human graders viewing the images produced by the device. It is not explicitly stated whether the ANTERION has an "algorithm only" mode that provides automated diagnoses without human review, but the clinical evaluation method suggests a focus on the quality of the images provided for human interpretation rather than fully automated standalone performance.
  6. Type of Ground Truth Used:

    • For Abnormality Identification: The slit lamp examination performed by the investigator was used as the reference (ground truth) for identifying abnormalities.
    • For Image Quality and Visibility of Structures: Expert consensus (majority rule of three masked graders) was used to grade image quality and visibility of structures on the OCT images from both devices.
  7. Sample Size for the Training Set:

    • The document does not provide information on the sample size used for the training set for the ANTERION device's algorithms or software. The clinical study described is a test set evaluation.
  8. How the Ground Truth for the Training Set Was Established:

    • The document does not provide this information. The clinical study details focus solely on the evaluation of the device's performance using a test set.

Tests for electrical safety (ANSI AAMI ES60601-1:2005/(R)2012 and A1:2012, C1:2009/(R)2012 and A2:2010/(R)2012) and electromagnetic radiation (EC 60601-1-2 Edition 4.0 2014-02) were performed with the Anterion device and passed the relevant requirements of the applied standards.

CLINICAL EVALUATION

A prospective, clinical study was conducted at a single clinical site in the United States to compare the clinical performance of the ANTERION Imaging App between the ANTERION and the CIRRUS HD-OCT 5000 devices. 87 participants age 22 or older meeting eligibility criteria in at least one eye were enrolled into two study cohorts, the "Normal Anterior Segment group" (without abnormality present in the anterior segment of the eye) and the "Abnormal Anterior Segment group" (those anterior segment abnormalities identified with the slit lamp exam such as glaucoma and corneal surgeries). One eye of each subject was selected to be the study eye, (randomly determined when both eyes were eligible).

The following endpoints were evaluated:

  • The image quality grade of the acquired images. ●
  • Agreement in identification of abnormality between the B-Scan images using the ● slit lamp examination as the reference.

{12}------------------------------------------------

An eye examination was performed to determine study eligibility, then inclusion and exclusion criteria were assessed. The anterior segment abnormalities and a primary Abnormality of Interest (AOI) were identified during the eye examination by the investigator (when applicable). The device order and the acquisition type order was randomized.

Imaging was performed by the site operators based on randomization

The first acceptable scans were sent to the Reading Center for grading. Each grader graded each image for image quality and for identification and assessment of abnormality (if applicable). The images were presented to three independent graders, who were blinded to the subject identification, population allocation, eye examination results and to each other's grading results. Majority rule was applied to get consensus. For each device and acquisition type (if applicable), three qualified graders graded the OCT images for quality into categorical groups (1 = poor, 2 = fair, 3 = good).

In each image the visibility of following structures was assessed:

  • Cornea/Conjunctiva ●
  • Iris (temporal/nasal) ●
  • Anterior Lens Surface
  • . Scleral Spur (temporal/nasal)
  • . Angles (temporal/nasal)

The graders also graded for presence or absence of pre-defined key abnormalities, specified on the grading form.

Eighty-seven subjects were enrolled in this study. Thirty-four in the Normal Anterior Segment population and fifty-three in the Abnormal Anterior Segment population.

The mean age was 45.7 ± 16.1 years overall, with the Abnormal Anterior Segment population subjects being older. The study population gender distribution was 67.9% male and 32.1% female. Sixty-seven percent (67%) were not Hispanic or Latino, 34% were Caucasian and 42% African American. The study eyes were fairly equally distributed between right and left eyes (51% right, 49% left).

To compare the image quality of the ANTERION and the CIRRUS devices, key anatomical structures were evaluated for image quality (Good/Fair/Poor) by the independent Reading Center by three masked graders.

{13}------------------------------------------------

Figure 1 below summarizes the structure image quality for all study eyes of the effectiveness analysis population. Overall, the ANTERION shows superiority in image quality compared to each of the three CIRRUS scans.

Image /page/13/Figure/3 description: The image is a set of bar charts that show the image quality of different structures in the eye, including the cornea/conjunctiva, anterior lens surface, iris, angle, and scleral spur. The image quality is measured using four categories: good, fair, poor, and no acceptable scans. The bar charts show the percentage of scans that fall into each category for each structure. For example, for the cornea/conjunctiva, 83.3% of scans are rated as good using the ANT scan type, while 52.6% of scans are rated as good using the CCN scan type.

There were no adverse event occurring during the course of the study.

The results of this study illustrated that when using OCT to visualize the anterior segment, ANTERION's overall OCT image quality and ability to visualize key anatomical structures on OCT images was similar to or better than CIRRUS for all scan patterns and all subject populations. Furthermore, using the slit lamp examination as a reference, the results indicate that ANTERION offers an equal or superior ability in identifying each pre-specified abnormality as compared to CIRRUS. Therefore, the study results support substantial equivalence of ANTERION and the CIRRUS 5000 with Anterior Segment Premier Module in regard to image quality, the ability to discern key anatomical structures, and the ability to identify various anterior segment abnormalities.

CONCLUSION

Comparison of intended use, technological characteristics, and clinical performance data as well as evaluation of non-clinical testing support substantial equivalence of the ANTERION subject device to the predicate and reference devices.
