How to adjust the instrument
Ask the patient to look relaxed at the yellow fixation light.
Focus on the iris, not on the peripheral points. Adequate room lighting
will facilitate detection of iris structures. Avoid direct exposure of eye
and instrument front panel to extraneous light.
Particularly take care that the visible right and left edge of the iris is not
disturbed by reflections from lamps and windows.
If the iris structure should not be discernible, focus on the edge of either
iris or pupil.
Larger degrees of defocussing will be result incorrect data.
After the image has been taken, the operator should check if the
software correctly detected the edge of the iris. If the circle segments
drawn in the image should not define the iris correctly, discard the
result. Click on
OK
to confirm the results and save the data.
