12 Icare HOME Patient Guide

POSITIONING THE TONOMETER

Stand in front of a mirror and hold the
5
tonometer sideways in front of your face.
This will help you to align the tonometer
to your eye.
WARNING
Make sure that the probe or any part of the
tonometer does not contact your eyes.
6
Align the probe tip with center of cornea
and rotate the tonometer until the
probe tip points straight at cornea.
WARNING
Make sure that the probe or any part of the
tonometer does not contact your eyes.
i
PRECAUTION
Do not cover the eye recognition sensors,
because covering the sensors causes an error.
7
Make sure the probe base light is green.
If the probe base light is red, make sure you
are facing straight ahead (i.e., head held at
a 90° angle) and tilt the tonometer until the
probe base light turns green.
8
Make sure the probe is centered in sight
to ensure the probe contacts the center of
the cornea during measurement.
If the probe is not centered in your sight,
repeat steps 5 and 6.
