LOADING THE PROBE
Accurate measurement is guaranteed only when using probes made by Icare

AFTER MEASURING
Press the measurement button.
BEFORE LOADING THE PROBE
Press the selector button.
MEASURING THE INTRAOCULAR PRESSURE
The tonometer needs to be in a
horizontal position
during the measurement. The
distance
should be 4-‐8 mm
(1/6 -‐ 1/3 inch) from the probe to the cornea.
TIP
The distance from the eye to probe should be about the lenght of the collar.
Six individual measurements are required for the final result. The measurement values
displayed during the measurement represents average values of the previous measurements
(1.-‐5.), not individual measurement values.
Press the measuring button six times. The tip of the probe needs to contact the
central
cornea
**. After each successful, individual measurement a short beep is played. After six
successful measurements, a longer beep is played and the final result is shown on the
display.
If there is an erroneous measurement, the tonometer will beep twice and show an error message. Press the measurement button to clear the error
message and continue the sequence of six measurements. The sequence of six individual measurements does not have to be started from beginning, the
tonometer will continue the sequence after cleared error message. If several erroneous measurements appear, see the section ”Error messages” (page 7).
Start a new measurement by pressing the measurement button. The display shows “00” indicating the tonometer is ready for the next measurement.
**IOP should always be measured from the central cornea to get the true value since the result vary in different parts of the eye
