Operation
CAUTION:
IT IS PRUDENT TO MINIMIZE THE PATIENT’S EXPOSURE TO ULTRASOUND
ENERGY TO A LEVEL AS LOW AS REASONABLY ACHIEVABLE (ALARA) BY REDUCING THE
NUMBER OF SCANS NEEDED TO BE PERFORMED. ADVISE THE PATIENT OF WHAT TO
EXPECT DURING A SCAN TO REDUCE REPETITIVE SCANS. THE AMERICAN INSTITUTE
OF ULTRASOUND IN MEDICINE (AIUM) HAS A PUBLICATION “MEDICAL ULTRASOUND
SAFETY” (1994) WHICH HAS MORE INFORMATION ON THIS TOPIC.
Operational Check
Measure the patient according to the following procedure and precautions.
WARNING:
DO NOT USE THE IPAC PACHYMETER IF THE MEASUREMENT TIP IS
CRACKED, CHIPPED OR SHOWS ANY IRREGULARITY OF THE SURFACE, TO PREVENT
PATIENT INJURY, AND/OR INACCURATE READINGS.
1. Before using, visually inspect the Pachymeter’s sensor for cracks, chips or other
irregularities. Do not use the pachymeter if the tip is cracked, chipped, or shows
any kind of irregularity of its surface.
2. Press and release the control button (
) to activate the iPac.
Note:
The instrument will automatically enter the power OFF sequence after inactiv-
ity of approximately one minute.
3. Check the battery icon to ensure that the battery is fully charged. If the iPac
needs charging, plug in the charger until the icon indicates that it is fully charged,
or place it in the iPac Charging Cradle.
CAUTION:
ALWAYS ENSURE THE IPAC IS CHARGED SUFFICIENTLY OR ERRATIC
READINGS MAY OCCUR.
Patient Preparation
1. Advise the patient of the measuring process and what to expect before taking
measurements.
2. Have the patient sit comfortably and install a drop of topical anesthetic into the
eye to be examined.
CAUTION:
DO NOT PUT ANESTHETIC DROPS ON THE MEASUREMENT TIP. THIS MAY RE-
SULT IN INACCURATE READINGS. TIP SHOULD BE DRY BEFORE TAKING MEASUREMENTS.
3. Give the patient the appropriate time for the anesthetic to start working.
