Accutome PachPen Manual
2. A single beep from the
instrument will indicate that all
measurements, averages, IOP
entries and calculations are set to
zero.
WARNING! THE PROBE TIP MUST BE
PROPERLY DISINFECTED BEFORE TAKING ANY
MEASUREMENTS ON A NEW PATIENT.
How to Take a Measurement
1. Touch and hold the Up and Down
Control Buttons on the PachPen simultaneously for 2 to 3 seconds to reset
all measurements, averages, and IOP information to zero.
2. Press and release the Action Control Button. Two high pitched chirps
(beeps) and a rotating line to the left of the average in the display indicate
that the PachPen is ready to take a reading.
3. Apply the probe to the patient’s eye.
4. The PachPen will automatically proceed to the next empty measurement if
it is available.
5. The PachPen will emit a high-pitched chirp (beep) when you have
automatically acquired a measurement.
6. The PachPen will emit three high-pitched chirps (beeps) when the nineth
measurement has been taken, or if the measurement time expires.
Notes
1. The PachPen can take up to nine measurements and provide the average
of those measurements. This average is the number used when calculating
the True IntraOccular Pressure (TIOP).
2. The * symbol by a measurement indicates the reading which is farthest
away from the average.
3. You can review the measurements taken by pressing the Up and Down
Control Buttons.
4. You can delete any measurement taken by touching and holding either the
Up or Down Control Button for several seconds (until the unit emits a high-
pitched chirp). After deleting a measurement, the unit will automatically
recalculate the average of the measurements.
How to Perform a Calculation
After you have completed a patient’s measurements, you can calculate the True IOP
for the patient. You can perform the calculation from the MIOP Screen.
To calculate True IOP:
1. From the Measurement Screen, select the MIOP screen by pressing and
holding the Action Control Button for 2 to 3 seconds.
2. Enter the measured IOP by pressing the Up and Down Control Buttons until
the proper measured IOP is displayed. If you make a mistake, just reselect
the correct value.
3. The True IOP based on the average of the measurements taken is displayed
below the measured IOP.
