Icare HOME tonometer Instruction manual for health care professionals
4. Bring the tonometer near the eye, the probe pointing perpendicular to
the center of the cornea without a vertical or horizontal tilt. The position
is correct when the probe base light is green and appears symmetrically
in the center of the patient's view. See Figure 23 and 24.
• Correct alignment of the tonometer (see Figure 25).
• Incorrect alignment of the tonometer (see Figure 26).
• Incorrect alignment of the tonometer. Readjust so that you see only
the front of the tonometer and the green light symmetrically in the
center of your view (see Figure 27).
5. Press the measurement button:
Single mode:
Press the button briefly (1 second) and you hear a short beep, repeat it
to take one measurement at a time till you hear a long beep and see the
Done light (17) illuminated on the back panel (Figure 28).
Series mode:
Keep the measurement button down to obtain the sequence of
six measurements till you hear a long beep and see the Done light
illuminated on the back panel. The button must be pressed for at least
3 seconds (Figure 29).
6. If both eyes are measured repeat steps 1-5 using your other eye.
7. If an error occurs, press the Measure button briefly (1 second) and
continue the measurement. See also section 12 Trouble shooting.
8. Press the power button for three seconds to turn the tonometer off.
The probe slides out of the probe base.
9. Remove and discard the used probe properly.

11. READING THE MEASUREMENT DATA

The tonometer stores information on every complete measurement sequence
of six measurements. The stored information includes the calculated final eye
pressure reading in mmHg, time and date of the measurement, identification
of the eye (right or left) and the quality level of the measurement. Uploading
is easy:
1. Start Icare LINK software in your PC (Figure 30).
2. 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.
3. The internal clock of the tonometer is automatically updated to the PC's
time by the Icare LINK software at this point (Figure 31).
4. Copy the data to a selected patient in the Icare LINK software (Figure 32).

position and speed of the probe during the measurements, and indicates
errors with sounds and lights. The following table instructs you in error
situations and explains what the different lights and sounds mean.
