In normal mode a value is shown briefly after each successful measurement. When the six measurements in sequence are completed and the
measurement result is valid, the final value range is displayed. If there is too much variation between the measurements, the REPEAT ERROR LED is
displayed and the measurement needs to be performed again. The device stores the quality of the measurement in its internal memory, which is
only accessible by downloading to a PC using the Icare® LINK software.
A new measurement needs to be taken if:
REPEAT ERROR LED is displayed, for example, if the probe made contact with the eyelid.
Encountering unusual values, for example, over 22 mmHg or below 8 mmHg.
The tonometer’s internal memory stores the time and date of a measurement, the measurement result and the quality level of the measurement.
This information can be uploaded to a PC through a USB cable using Icare® LINK software. The tonometer is taken to a health care professional who
can transfer the data.
NOTE
When using Icare LINK software, it assumes by default that the first accepted measurement is for the right eye and the second accepted
measurement is for the left eye.

PATIENT USE INSTRUCTIONS
When taking measurements:
NOTE
Before performing self tonometry the patient must have the tonometer set up by a health care professional. The doctor or nurse has adjusted the
distance between the tip of the probe and the center of the cornea with the forehead and cheek support to be 4-8 mm, (5/32-5/16 inch).
NOTE
The tonometer must be held in a vertical position. Angle of inclination has limited to ± 22° to ensure reliable outcome.
Doctor or nurse has adjusted the measurement position.
Doctor or nurse has demonstrated to the patient how to use the tonometer
1.
Switch on the unit, load the probe
2.
Go in front of a wall mirror
3.
Take the tonometer in your hand with the white main button pointing upwards
4.
Move the tonometer sideways toward your eye so that you see in the mirror the white tip of the probe in front of the black pupil
5.
Move the tonometer closer so that the forehead and cheek supports touch the skin
6.
Check that the white tip of the probe is seen in front of the center of the cornea (pupil)
7.
Turn the tonometer from the sideway position so that the tonometer with the loaded probe points straight to the center of the cornea
(pupil)
8.
Open your eyes wide and try not to blink your eye while measuring
9.
Press the measurement button once. You will get the final result after the probe touched you eye for six times and after one long beep.
In automatic mode the six interim measurements are taken in sequence.
CAUTION!
Always perform measurement on RIGHT eye first followed by LEFT eye. Complete the RIGHT eye measurement sequence before changing to the
LEFT eye.
