Scout Installation and Operating Manual
OPTIKON 2000
It is advisable that, as your first training experience, you take 6-8 pictures on the
same eye and to check their repeatability by “Acquire”, “Repeatability Check” menu,
until this is good.
As a standard procedure, you are then suggested to take 3-4 pictures per eye in
order to check repeatability, and then to save only the best one (or two)
Caution
:
To move the Scout do not use its handle, but the slit lamp joystick. Use
the footswitch to acquire, and avoid using the OK key.
During the acquisition of an image, the Keratron
®
Scout emits a series of “beeps”
changing in pitch and rhythm. This is meant to be an audio cue for the operator when
aligning an eye for image capture. Listen to the beeps to get familiar with the cues.
Perfect focus has its own distinct sound. The audio cues enable you to concentrate
more on the video image on the CRT rather than on the arrow indicators.
Suggestion:
To obtain a quick and reliable acquisition, go just a little closer to the
eye than OK, ask the patient to blink then to OPEN BOTH EYES WIDE then, keeping
the switch pressed, move back slowly and thus acquire the image automatically. If
the patient blinks, discard the photo and repeat.
Once you have captured an image by pressing the footswitch – or the OK key if the
PC is in acquisition mode -, the image will be automatically transferred and added to
the previous ones. If you press the CLR key, you can delete the image last taken.
7.3.2 THE PORTABLE CONFIGURATION
Acquisition in portable or handheld mode is affected by a larger number of perturbing
factors than with LAF (both patient’s and operator’s movements, and possible
rotations in 3D) and therefore it requires more experience and practice.
Nevertheless, after a short training, and with the following trick-and-tips, it is possible
to learn to take quickly results having a repeatability as good as those that can be
obtained with the Slit Lamp configuration.
1. Sit the patient so that his head touches a wall without tilting up, and so to
stay just in a higher position than he is (fig. 6).
2. Put the disk extension of the headrest steady on the patient’s forehead,
possibly helping with the other hand.
