D-KAT Tonometer by KEELER
Cause:
If during measurement the slit lamp is moved forward toward the patient or the patient
moves toward the slit lamp, the sensor arm will be pushed into contact with a stop spring
and an audible alarm will sound. The applanation surface will be too large. The image will
not change when the measurement drum is rotated.
Correction:
Retract the slit lamp until regular pulses and a correspondingly smaller applanation surface
are obtained. This is the correct measurement position, in which variations in pressure will
not cause immediate variations in the applanation surface.
8.3 THE TWO SEMICIRCLES ARE NOT CENTRAL IN THE FIELD OF VISION
Correction:
Using the joystick, move the slit lamp up
and to the left.
Cause:
The rings are too far to the right.
Correction:
Using the joystick, move the slit lamp to
the right.
Cause:
The reading in this position is considerably
higher than real ocular pressure.
Correction:
Using the slit lamp height adjustment
mechanism, lower the slit lamp until the two
fluorescein semi circles are equal in size.
The measurement pressure will then be
reduced.
