Intended Use

The Tomey Cornea/Anterior Segment OCT CASIA2 is a non-contact, high resolution tomographic and biomicrosopic device indicated for the in vivo imaging of ocular structures in the anterior segment. The Tomey Cornea/Anterior Segment OCT CASIA2 is indicated as an aid in the visualization of anterior segment findings.

Device Story

CASIA2 is a non-contact, high-resolution swept-source optical coherence tomography (SS-OCT) system for anterior segment imaging. It captures backscattered light intensity to generate cross-sectional tomographic images of the cornea, lens, iris, and iridocorneal angle. Operated by clinicians in a clinical setting, the device uses a 1310 nm swept-source laser to perform A-scans at 50,000 scans/second. The system includes a main unit, touch panel monitor, and external storage. Output consists of high-resolution images displayed on the monitor, which the clinician uses to visualize ocular structures and pathology. By providing detailed cross-sectional views of the anterior chamber, the device assists in the assessment of ocular conditions, potentially improving diagnostic accuracy and clinical decision-making regarding anterior segment diseases.

Clinical Evidence

Prospective comparative study of 134 subjects (45 normal, 46 cataract, 43 glaucoma). Image quality and visibility of anatomic structures (cornea, angle, lens, iris) were compared against the Optovue RTVue Avanti by 3 masked graders. Results showed CASIA2 provided better overall image quality in the pooled population and individual subgroups. Pathology was observed more frequently with CASIA2 images. Visibility of angle and lens was superior with CASIA2; cornea visibility was equivalent; iris visibility was equivalent or superior depending on scan type.

Technological Characteristics

Swept-source OCT; 1310 nm laser source; 50,000 A-scans/s; 13 mm depth scan range. Includes internal fixation, accommodation, external alignment, and front illumination (red/green) LED lamps. Connectivity via Windows-based PC. Complies with ISO 15004-1, IEC 60601-1, ANSI Z80.36, ISO 10993-1, and IEC 62304. Biocompatible materials per ISO 10993-1.

Indications for Use

Indicated for in vivo imaging of anterior segment ocular structures (cornea, iris, lens, iridocorneal angle) in patients, including those with cataracts or glaucoma, to aid in visualization of anterior segment findings.

#### Description of the Device 3.

The Tomey Cornea/Anterior Segment OCT CASIA2 (CASIA2) is a non-contact, high resolution tomographic and biomicroscopic device indicated for in vivo imaging of ocular structures in the anterior segment. The Tomey Cornea/Anterior Segment OCT CASIA2 is indicated as an aid in the visualization of anterior segment findings.

CASIA2 consists of several components: the main unit, AC input power source, a touch panel LCD monitor, an external hard drive (HDD), a mouse and a keyboard.

There are two types of OCT, which are based on different measurement principles: time domain (TD) and Fourier domain (FD). In the TD, the reference mirror is moved mechanically in the direction of depth; in the FD, the depth-wise tissue data is obtained without moving the reference mirror. With the FD, since the reference mirror does not need to be moved mechanically, images can be obtained at a higher speed compared to the TD.

The FD is further classified into spectral-domain OCT Idetected in Fourier space using broadband light source and spectroscope (grating) without moving the reference mirror] and swept-source OCT (optical interference performed in the Fourier space by changing the wavelength of the light source at a high speed).

CASIA2 is an anterior segment OCT that obtains images by A-scanning with swept-source OCT. OCT images are created by the intensity of the light (backscattered light) that returns in the same path as that of incident light among the scattered light of each tissue. Thus, it is created with higher intensity in the tissues that generate strong backward scattering.

The various structures which are imaged, and the related scans include the following:

- . Cornea
- 0 AS Global scan
- 0 AS H+V Scan
- O AS Single
- Lens ●
- Lens scan O
- Lens Raster O
