Instrument Operation

Measurement Process

4. Instruct the patient to look straight ahead at a
fixation target (e.g., ear, nose, distant object) to
minimize eye movement, with eyes fully open to
prepare for a measurement.
5. Hold the iPac Pachymeter as you would a pencil
and to enable viewing of the sensor and the
patient's cornea where contact will be made. For
normal corneas, central corneal contact is highly
recommended.
Note: The corneal surface needs only to be contacted
for a short time. Indentation or additional pressure
is not required and may lead to injury to the eye.
Note: Do not 'tap' the iPac on the cornea. Hold it
steadily against the cornea.
6. Support the iPac with your hand, and if necessary,
stabilize the movement of the iPac by resting your
hand against the patient.
7. Press and release the Control button, one time (
). The iPac will initiate the measurement
process and beep once. After the beep, three
asterisks are displayed.
8. Minimizing the time the Pachymeter is touching
the eye, lightly touch the center of the cornea until
the iPac completes a series of beeps followed by
a single beep.
9. After the series of beeps and the final beep,
remove the iPac from the eye. The iPac will
display the average reading.
