7.4 TAKING THE MEASUREMENTS
WARNING!
Do not bring the tonometer into contact with the eye or push it into the eye (the tip of the
probe should be 4-8mm, or 5/32-5/16”, from the eye).
The probe will make a gentle and brief contact with the eye when you take the
measurement. No topical anesthetic is needed.
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.
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.

long beep and see the Done light illuminated on
the back panel.
