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.

Instructions for the health care professional
Instruction for the patient
1.
Check that the tonometer is set up correctly by a
doctor or a nurse.
2.
The patient should relax, and look straight ahead at a
specific point while keeping eyes wide open.
3.
Bring the tonometer near the eye. Move the
tonometer closer so that the forehead and cheek
support touch the skin. Check that the white tip of the
probe is seen in front of the center of the cornea
(pupil). The distance from the tip of the probe to the
center of the cornea must be 4-8 mm (5/32-5/16 inch).
4.
Press the measurement button lightly to perform the
measurement, taking care not to shake the tonometer.
The tip of the probe should make contact with the
central cornea (pupil). The way you take
measurements depends on the chosen mode.
5.
In normal mode a value is shown briefly after each
successful measurement. When the six measurements
in sequence are completed and the measurement
valid, the final value of IOP 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.
6.
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.
7.
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. If a patient does not have the
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. In case you end up taking
multiple measurements for some reason, the eye details can be
incorrect and must be fixed (See Icare LINK user manual).
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
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.
A new measurement needs to be taken if:
REPEAT ERROR LED is displayed, for example, if the
probe made contact with the eyelid.
