3. Tilt the cone possibly in its horizontal position. Only with patients having a
leaned forehead or with children orientate the cone to 5° or 10° upwards (1
or 2 clicks). In such cases, however, you could need to be even higher
than the patient. The cone should however approach close to the eyebrow
(figures 7), so to avoid that the lower lid covers the eye too much (figures
8).
4. Press OD or OS to start acquisition. Get near to the eye until reaching the
OK position.
5.
Take care that the protrusions of the mires cone do not hurt the
patient’s eye!
To avoid this, it is important that you centre the reflected
rings with the cross in the display from the very beginning and that you
keep them centred at all time while you advance by pushing on the
headrest up to reach the OK position. Avoid pivoting sideways the VK by
your holding hand and instead looking for the optimal point where to place
the headrest disk, with the help, if necessary, of the other hand.
6. Ask to the patient to blink and then to open wide both eyes. Then get close
by slightly overcoming the OK position, press and keep pressed the OK
button and then get back very slowly until you get an automatic capture.
7. If the picture is moved, then erase it at once by pressing CLR and then
proceed with next acquisition. Capture up to 8 picture (at your first
experience) on the same eye and 3-4 per eye, in your daily practice. On
the PC, discard only the very moved or bad ones and then run “Process
All”. Do “Acquire” “Repeatability Check” and repeat until you can get good
results. Eventually save only the 1 or 2 best ones.
