Icare HOME tonometer Instruction manual for health care professionals
2. Turning the tonometer on:
• Press the power button. All indicator lights on the back panel will flash
once and you will hear a short beep.
• The Load light will flash alone when the tonometer is ready to load the
probe.
• The tonometer turns off automatically after 3 minutes if you do not
use it.
3. Loading the probe:
• Unwrap the probe.
• Remove the lid of the probe container.
• By holding the probe container drop the probe into the probe base
without touching the probe.
• Press the measurement (play) button briefly (1 second) to activate the
probe.
4. Adjusting the measurement distance:
• Carefully, without touching the patient's eye, set the distance between
the tip of the probe and the center of the cornea for the patient at
4-8mm (5/32-5/16") by turning knobs to adjust forehead and cheek
support positioning as needed.
• Write the settings down on a support position tag for the patient.
• Repeat for the patient's other eye.
5. Explain and show illustrations for how to position the tonometer (use a
separate illustration sheet from the labeling for this):
• Sit or stand in front of a mirror and hold the tonometer sideways in
front of your face.
• Align probe tip with center of cornea and rotate the tonometer until
probe tip points straight at cornea.
• Make sure probe base light is green. If probe base light is red, make
sure you are facing straight ahead (i.e., head held at a 90° angle) and
tilt tonometer until probe base light turns green.
• The probe base light does not turn red in response to horizontal
deviations. For this reason make sure the probe is centered in sight to
ensure the probe contacts the center of cornea during measurement
even if the probe base light is green. If the probe is not centered
in your sight, repeat 5 and 6. This is very important because the
tonometer with the probe must not be tilted more than 10 degrees
away from the center of the cornea and without visualizing the probe
base light it is difficult to judge the horizontal angle of the device.
6. Explain how to take the measurement:
• Explain that the Measure light will flash when the tonometer is ready
to measure.
• Explain that the user must take six individual measurements for the
IOP result and that the results are stored in the tonometer.
• Explain that the measurement button must be depressed to obtain the
sequence of 6 measurements until a long beep is heard and the green
"Done" light is illuminated on the back panel. The probe base light
turns off at the same time.

7. Show and explain how to collect, display and store the results (for HCPs only):
• Start Icare LINK software in your PC by clicking the Icare LINK icon
• Connect the tonometer to the PC using the USB cable. The Load and
Measure lights will flash. If no lights flash or the Service and Battery
lights flash, reconnect the USB cable.
• (The internal clock of the tonometer is automatically updated to the
PC's time by the Icare LINK software at this point).
• Icare LINK software's device tab opens and you see the results.
• Copy the results to a selected patient (it can be the default patient
"-New patient-" that you can rename afterwards).
• The Measurements tab opens showing the copied results with date
and time information that all is now stored to the PC.
STEP 3 – Rehearsal
HCP:
1. Position the tonometer on your (HCP trainer) own eye.
2. Ask HCPs, if a given training session includes multiple health care providers, to
observe and learn.
3. Load a new probe, ask the HCPs to position the tonometer and take some self-
measurements as instructed and demonstrated.
4. Observe each HCP and, if necessary, correct the position while the HCP positions
the tonometer, say to the HCP that this is the correct position and ask the HCP to try
again.
5. Repeat 1-3 for up to ten times until the HCPs show consistent device positioning.
CAREGIVER:
6. Position the tonometer on another trainer's eye.
7. Ask the caregiver to observe and learn.
8. Load a new probe and ask the caregiver to position the tonometer on another
trainer's eye and to take some measurements as instructed and demonstrated.
9. Observe and, if necessary, correct the position while the caregiver positions the
tonometer, say to the caregiver that this is the correct position and ask the caregiver
to try again.
10. Repeat 1-3 for up to ten times until the caregiver shows consistent device
positioning.
STEP 4 – Reference measurement
HCP:
1. Load a new probe and carefully measure the IOP of the HCP with the tonometer once
in each eye.
CAREGIVER:
2. Load a new probe and carefully measure the IOP of another trainer once in each eye
with the tonometer.
