TAKING THE MEASUREMENTS

WARNING!
Do not push the tonometer into the eye (the tip of the probe should be 4-8mm, or 5/32-5/16", from
the eye).
WARNING!
The probe should be replaced if it contacts or is suspected of having contacted the eyelashes or
eyelid such as might occur during a blink.
The probe will make a gentle and brief contact with the eye when you take the
measurement. No topical anesthetic is needed. The recommended frequency of
measurements is 3-4 daily with a maximum of 5-6.
To measure intraocular pressure:
1. Check that the Measure light (15) still flashes on the back panel.
2. If the Measure light does not flash, press the power button (20) and wait until
the Measure light illuminates again.
3. The patient should look straight ahead at a specific point while keeping eyes
wide open as shown in the below figure.
Correct head and eye position.
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 the below figures.
