CAUTION : Federal law restricts this device to the sale by or on the order of a physician.
Thank you for purchasing the TOPCON DRI OCT-1 Model Triton 3D Optical Coherence Tomography.
The TOPCON DRI OCT-1 Model Triton is a non-contact, high-resolution tomographic and bio-micro­scopic imaging device. It is indicated for in-vivo viewing, axial cross-sectional and three dimensional imaging, and measurement of posterior ocular structures, including the retina, retinal nerve fiber layer, ganglion cell plus inner plexiform layer, ganglion cell complex, macula, optic nerve head, and choroid. The DRI OCT-1 Model Triton is intended for use as a diagnostic device to aid in the detec­tion and management of ocular diseases including, but not limited to, macular holes, cystoid macu­lar edema, diabetic retinopathy, age-related macular degeneration, and glaucoma.
FEATURES
This instrument is a special photography device to observe, photograph and record the image and tomogram of fundus and the image of anterior segment and to present its electronic image for diag­nosis. By mounting the anterior segment attachment kit, which is an optional accessory, you can observe, photograph and record the tomogram of anterior segment. After photographing, the images and tomograms of fundus and anterior segment can be recorded in a personal computer where the analysis software is installed. This instrument is classified into two types depending on the combination of the installed functions:
DRI OCT-1 Model Triton:Not equipped with the FA photography function and with the FAF
photography function.
DRI OCT-1 Model Triton plus*:Equipped with the FA photography function and with the FAF
photography function.
(* "plus" is a catalog symbol.)
PURPOSE OF THIS MANUAL
This manual outlines the DRI OCT-1 Model Triton 3D Optical Coherence Tomography, including operating procedures, troubleshooting, maintenance and cleaning. Before using the instrument, carefully read the "DISPLAYS AND SYMBOLS FOR SAFE USE" and the "GENERAL SAFETY INFORMATION" to familiarize yourself with the features of the TOPCON DRI OCT-1 Model Triton 3D Optical Coherence Tomography and to ensure that you operate it safely. Always keep this User Manual at hand.

CONTRAINDICATION
When used for red-free photography only, this instrument must not be used for the following patients.
• Patients who are hypersensitive to light
• Patients who recently underwent photodynamic therapy (PDT)
• Patients taking medication that causes photosensitivity.
WARNING
Ensuring the Safety of Patients and Operators
Be careful not to hit the patient's eyes or nose with the instrument during operation. The patient may be injured.
Handling the cord on this product or cords associated with accessories sold with this product, will expose you to lead, a chemical known to the State of California to cause birth detects or other reproductive harm.

Scan possible range (red) Displayed only for "5 Line Cross" and "Radial" scan patterns. This range shows the "12.0mm×
12.0mm" range at the focal point on fundus. This is the limit range where you can get a tomogram by using this instrument. If a tomogram exceeds the range indicated by the blue line, you cannot always get the sufficient output sensitivity because the pupil and others obstruct the photography.
Fine adjustment buttons (up/down/right/left) Each time you touch these buttons, the scan position is moved by about 0.03mm (on fundus) in the arrow direction.
Rotation buttons (clockwise/counterclockwise) Displayed only for "Line" and "5 Line Cross" scans. Each time you touch these buttons, the scan line is rotated by 1° in the arrow direction.

• Image Quality value (IQV) is the image quality evaluation standard peculiar to TOPCON. IQV shows the image quality of the tomograms obtained by the DRI OCT-1 Model Triton with a value quantitatively. When you need a tomogram applicable to image analysis or other processing, the IQV must be 40 or
NOTE
higher. If the IQV is 40 or higher, the tomogram has a proper image quality. If the IQV is less than 40, image analysis can be performed for the tomogram but the reliability on the analysis result is reduced. So the tomogram is not applicable for analysis.
• If only the images of poor image quality are obtained, contact your dealer or TOPCON listed on the back cover.
