Slit Lamp Adapted Optical Coherence Tomography
SL SCAN-1
Optical Coherence Tomography (OCT) technology createda revolution in the fundus diagnostic field more than a decade ago. With the introduction of the world’s first commercialised Fourier Domain OCT, 3D OCT-1000 in 2005, Topcon made a further revolution in this field offering the combination ofa retinal camera with high resolution 3D OCT image.
Topcon is proud to introduce the world’s first slit lamp adapted posterior and anterior segment Fourier Domain OCT, SL SCan-1. With the SL SCan-1, OCT examination becomes available from the first consultation increasing efficiency and accuracy of diagnosis. Patient comfort is also improved by reduction in examination time.

Ultimate Optimisation of Patient Flow by the SL SCAN-1
The Topcon SL SCAN-1 enables observation, capture and recording of high resolution cross-sectional images of the anterior and posterior pole of the eye with a biomicroscope. The integration of superior imaging technology, OCT with Topcon’s leading slit lamp range enhances diagnostic capabilities significantly. With SL SCAN-1 many depth related disorders can be clearly and easily observed using a standard slit lamp examination.
With the SL SCAN-1, OCT examination becomes available from the first consultation.
The SL SCAN-1 requires minimal operation to obtain the desired OCT B-Scan images. A simple, compact addition to Topcon’s digital range of slit lamps the SL SCAN-1 does not sacrifice a single function of the Topcon slit lamp.The high resolution OCT image provides detailed and precise readings for further treatments such as Fluorescein fundus photography, 3D OCT scanning and the follow up of surgery, laser treatment and anti VEGF injection.

The SL SCAN-1 provides high resolution OCT images of the posterior and anterior section.
The B-Scan length of the SL SCAN-1 on the fundus is 12mm wide covering approximately 40 degrees of the fundus view providing scanning of a large peripheral area of the fundus.
Using Topcon SL SCAN-1 in combination with an add-on digital camera allows the user to record an en-face image taken by the camera and the cross section image taken by the OCT system simultaneously. Both can be stored on standard PC allowing you to view and analyse data at a later stage.
Various Scan Patterns
The SL SCAN-1 is equipped with the various scan patterns for your desired use.
All scan patterns are configurable in number of B-scan lenghts and resolution.
With the SL SCAN-1, B-scan acquisition of the peripheral retina is possible.

With the SL SCAN-1, B-scan acquisition is possible on any part of the retina including extreme peripheral area using a hand held lens.
Full 12mm scan on retina allows the user to capture both macula and optic disc in one B-Scan.

Easy Operation of SL SCAN-1
The SL SCAN-1 requires minimal operation to obtain the desired OCT B-scan images, in fact the operation is so minimal that it does not sacrifice a single function of the Topcon slit lamp.
User can view the retina via hand held lens as usual.
The operator can press the joystick button to capture/record B-scan images, continuing to do so until the desired image is captured.
Once joystick is pressed, the scan line is projected on the retina/anterior chamber and the live B-Scan will be displayed on the monitor.
The user may report on the images captured to IMAGEnet i-base, where they can be viewed remotely via a network.

DV-3
• The DV-3 incorporates a digital camera designed for high-resolution image acquisition.
• A C-MOS sensor provides a resolution up to 3.14 million pixels in a 10-bit digital output.
• “What you see is what you get”. The image on the monitor screen is equal to the image seen through the oculars of the slit-lamp. With traditional SLR cameras this is not the case. DV-3 offers the best ease-of-use.
• The DV-3 mounts a yellow filter and diaphragm unit for improved image quality.
With SL SCAN-1 it is possible to use conventional handheld lenses to observe the retina and capture the OCT image.
Using the Topcon SL SCAN-1 in combination with an add-on digital camera DC-3 or DV-3 allows the user to record an en-face image with the automated digital scan line taken by the camera and the cross section image taken by the OCT system simultaneously.
Aperture Selector, FV-1A Reduces reflection to optimise the fundus observation.
(This unit can be used
independently from the SL SCAN-1
and/or FV-1L. It can be used with
the conventional lenses.)
Lens Holder, FV-1LApproximately 30 degree fundus image observed. With the combination of image recording devices such as the DC-3 or DV-3, the slit lamp can become a basic fundus camera.

DC -3
• The DC-3 is the perfect combination for still imaging and live image.
• Integrated imaging solution with a phenomenal 8.3 Megapixel CCD sensor.
• Equipped with an exceptional resolution of 1 Megapixel life image.
PosteriorAnterior
Without the DC-3/DV-3, four kinds of digital drawing of various segments of eye are
available to record scanned area manually.
With or without the DC-3/DV-3, registration of scanned area can be recorded in the SL SCAN-1 software
(Standard Option).
With the DC-3/DV-3, scan pattern is automatically recorded on the retina / anterior image.
