– Measurement of corneal thickness and anterior chamber depth

* Auto alignment/Auto shot
* Corneal shape analysis

The time for capture an image has been reduced by introducing the Swept 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 OCTdoes not make contact with the eye, images of the 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 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 10 m or less, wich cannot be displayed by displayed by the OCT that employs the wavelength of approximately 840 nm used for the retina. The wide scanning range of 16 nm 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 operatorcan capture images and perform necessary analysis as many times as
needed.

Casia provides high-resolution imagesfor wide variety of clinical situations

• Axial (anterior, posterior, real)
• Instantaneous (anterior, posterior, real)
• Refractive (anterior)
• Elevation (anterior, posterior)
• Pachymetry
• And more

Narrow Angle
This image shows that the angles are closed. Since three-dimensional image is captured,
the gonioscopic data of 360º can be obtained.

Anterior chamber angle analysis

Lasik eye
The flap of Lasik is shown. Since Casia does not touch the eye, an image immediately
after the surgery can be captured.
