Cornea/Anterior Segment “Swept Source” OCT Scanner
The Cornea/Anterior Segment OCT SS-1000 “CASIA” is a non-contact, non-invasive three dimensional imaging system based on the principle of “Swept Source” OCT. This system achieves high resolution imaging of 10 µm (Axial) and 30 µm (Transverse) and high speed scanning of 30,000 A-scans per second.
The CASIA is indicated for cross sectional imaging of the anterior segment components of the human eye such as the cornea, the anterior chamber and the bleb segment of the sclera, and also for dimension measurements of these such as curvature, length, area and volume by computed analysis.
- Fourier Domain OCT
- High resolution images of the arbitrary area at high speed
- Less motion artifacts with fast acquisition
- Fulfillment of the useful application and utility software
- Measurement of corneal curvature
- Anterior chamber angle analysis
- Bleb segment analysis
- Measurement of corneal thickness and anterior chamber depth
- Auto alignment/Auto Shot
- Corneal shape analysis CASIA provides high-resolution images for wide variety of clinical situations.
The time for capturing an image has been reduced by introducing the Swept Source system for measurement which is one of the Fourier Domain systems. Since a three-dimensional data can be captured only within 0.3 ~ 2.4 seconds, the motion artifact due to eye movement and/or faulty fixing of the eye can be minimized. Since the Cornea/Anterior Segment OCT does not make contact with the eye, images of the eye immediately after a surgery can also be captured.
In addition, the Cornea/ Anterior Segment OCT allows you to obtain the data of the anterior segment of the eye with corneal opacity which is difficult to be observed with the slit lamp, etc. The light source is of the wavelength of 1310 nm which penetrates the tissue deeper to capture fine images of angle recess with the axial resolution of 10µm or less, which cannot be displayed by the OCT that employs the wavelength of approximately 840 nm used for the retina. The wide scanning range of 16 mm allows you to observe the area from the angle on the ear side to that on the nose side at once. The captured data can be analyzed with various applications to quantify the data. Since the three-dimensional data can be captured by simple operations, even a new operator can capture images and perform necessary analysis as many times as needed.
