Adjusting The Measurement Position; Measuring Intraocular Pressure (Iop); Results - Icare PRO TA03-026-1.0 Manual De Instrucciones

Icare tonometer PRO manual
activation, the device will magnetize the
probe (the probe will move rapidly backwards
and forwards). Once you have activated
the probe, the tonometer will be ready to
perform measurements.

6.4 ADJUSTING THE MEASUREMENT POSITION

WARNING
Do not bring the tonometer into contact with
the eye or push it into the eye (the tip of the
probe should be 3–7 mm, or 1/8 – 9/32 of an
inch, from the eye).
CAUTION
If you do not use the tonometer when it is
switched on, it will turn off automatically after
3 minutes.
The Icare PRO tonometer allows measurements
to be performed on supine patients and
patients in a normal upright (sitting/standing)
position. To adjust the position of the patient:
1. Ask the patient to look straight ahead with
both eyes open and keeping his or her chin in
a horizontal position.
2. To ensure that the measurements are
correct, keep the probe as perpendicular to
the center of the cornea as possible.
3. If you need to correct the position of the
patient, the device will display an error
message.
4. The tonometer has an adjustable forehead
support to ensure that the measurement
distance and alignment are correct. Adjust
the forehead support using the adjustment
wheel, so that the distance from the tip of the
probe to the surface of the cornea is 3-7mm
(1/8 – 9/32 of an inch) (Figure 5).
5. When you are measuring the intraocular
pressure of a supine patient, the probe will
not drop because the tonometer will hold the
probe in place. Once the probe is in the right
position, an arrow will appear on the display
indicating that the position of the probe is
sufficiently vertical for the performance of a
successful measurement (Figure 6).
7. MEASURING INTRAOCULAR PRESSURE
(IOP)
A measurement sequence is a series of six
measurements.

CAUTION
No anesthetic is required when performing
measurements.
CAUTION
If you do not use the tonometer, it will switch
off automatically after 3 minutes.
To measure intraocular pressure:
1. Check that the tonometer is set up correctly.
2. Go to Menu –> Measure and press the main
button. Use the left and right navigation
buttons to select the eye you want to
measure and press the main button to
confirm (Figure 7).
3. Tell the patient to relax and look straight
ahead at a specific point while keeping his or
her eyes wide open.
4. Bring the tonometer near the eye. The
distance from the tip of the probe to the
cornea must be 3-7mm (1/8 – 9/32 of an
inch), as shown in the figure (Figure 5).
If necessary, adjust the distance using
the forehead support. Keep the probe
perpendicular to the center of the cornea.
5. Press the main button lightly to perform
one individual measurement, taking care
not to shake the tonometer. The tip of the
probe should make contact with the central
cornea. A short beep will sound after each
measurement and the device will display a
reading.
6. Repeat step 5 six times. Once the six
measurements are complete, the device will
display the final IOP reading.
7. Press the main button.
8. Choose YES to continue measuring the other
eye of the same patient. Use the navigation
button to select the eye you want to measure
and then press the main button (OD/OS).
9. If you do not want to continue measuring,
choose NO. You can turn off the device from
the main menu, or leave it idle.

7.1 RESULTS

The device displays the reading after each
measurement within the series of six as an
average of the measurements taken until then.
The reading shown after the sixth measurement
is an average of four readings calculated after
discarding the highest and lowest reading
(Figure 8).
