MEASUREMENT
Ask the patient to relax and look
1.
straight
ahead at a specific point
to keep the eye
steady during the measurement.
Bring the tonometer near the patient’s eye.
2.
Check that the
central groove is in a horizon-
tal position
. It’s not necessary to look at the
display during the measurement since the
device gives sound signals about errors etc.
Keep the distance from the tip of the probe

to the patient’s cornea at
4 to 8 millimeters

forehead support.
Press the measuring button lightly. The tip of

the
probe should make contact with the

correct measurements are done, the IOP will
