8 CONDUCTING EXAMINATION
There are three modes of acquiring the examination available: Full Auto, Semi Auto and
Manual mode. See details in chapter 8.3 Acquisition modes description
Preparation for examination
Check patient’s pupil size. In case of narrow pupil, it might be necessary to dilate the patient’s
eye. Dilation is optional. The pupils of the examined eyes must be at least 2.45 mm in
diameter. Tomograms acquired through too small pupils may be dark on the edges, or the
SOCT signal may be weak, leading to lack of image intensity and clarity.
1. From the main window, select the patient you want to examine. Fast search mechanism
can be used to locate patients easily. If the patient is not on the list, perform the
registration. See chapter 6. PATIENT WINDOW
2. Verify the patient refraction. If the refraction value is higher than -/+5D add this
information to patient’s data (Edit Patient). See chapter 6.2 Registering new patients
3. Click 'Acquire’ tab from main window. Make sure that the proper patient is selected (look
at the upper right corner of examination window). See chapter 7. EXAMINATION

Scanning programs description) or Protocol (see chapter 7.3 Selection of protocol) and
acquisition mode (see chapter 8.2 Acquisition modes description). The way of Acquisition
mode should be selected (Full Auto-select checkbox, Semi Auto or Manual)
5. Tell the patient to sit in front of the device. Adjust the height of the table to seat the patient
comfortably. Place patient's chin on the chinrest and ask the patient to rest his/her head
firmly on chinrest and forehead support. Using the Chinrest control buttons adjust the
elevation of patient's head. Canthus has to be on the reference position on the forehead
frame. Advice the patient to look straight ahead then after its visible focus on blinking
fixation point and do not follow the scanning beam.
WARNING: Make sure, that patient does not put his head inside the frame when
“up” or “down” chinrest elevation button is pressed.
6. Change the eye if required, press [L] or [R] button to choose the desired eye.
7. When the system recognizes the pupil [START] button becomes active. If the pupil is not
visible on the eye preview, it is required to move the scanning head to left/right and/or
back/forth slightly to allow pupil detection. It is also possible to click on the eye preview
(left mouse button or touch screen press) to move the head to desired location. See
chapter 7.4 Device head movement controls and 7.5 Eye preview).
