Position the Ocu-Film
applicator on the transducer.
Roll the Ocu-Film tip cover
onto the Tono-Pen tip and
remove applicator.
To initiate an IOP measurement, press and release the operating
button
once; you will see a brief display of [88888] as a self-test of the
LCD. If any
segments are not lled, please contact Reichert Technical
Service at 888-849-8955.
When the TONO-PEN AVIA tonometer is ready to measure, the LCD
will
display a double row of dashes, [= = = ] the green LED will light, and
the device will beep.
Tap the sensor very lightly and briey on the corneal surface. The
TONO-PEN AVIA tonometer will chirp with each applanation, and
the DATA eld on the LCD will increment for each valid IOP reading
obtained.
Note: If upon pressing the operating button, the LCD display shows
[dn], the TONO-PEN AVIA tonometer will need to successfully pass
verication before a measurement can be obtained. See reverse side
for verication instructions.
When another beep tone is heard, indicating 10 applanations have
been read, the LED will turn off, and the averaged IOP measurement
will appear on the LCD above “mmHg”. The statistical condence
indicator will appear on the LCD above “DATA”. The higher the
statistical condence indicator, the more reliable the measurement.
If at least 6 but less than 10 applanations were obtained, the IOP will
be
displayed after a 4 second delay, along with the statistical condence
indica
tor. If 15 seconds elapse prior to applanation being initiated,
the
TONO-PEN AVIA tonometer will initate the sleep mode, indicated
initially by the display of a single row of dashes [
- - - ], followed by a
blank display. The applanation mode may be initiated by pressing the
operating button.
Proper set up of the Ocu-Film
®
tip cover is essential for the precision and accuracy of the tonometry measurement.
The application procedure below should be followed. A new Ocu-Film tip cover must be used for each new patient.
Be certain that the lm is at across the tip, but not too taut or too loose.

4. After cleaning the tip of the tonometer with compressed air,
the tip will be cold. Allow the tip of the tonometer to warm to room
temperature.
5. Perform the tonometer calibration as indicated in the TONO-PEN
AVIA Verication section of this Manual.
Note: If the tonometer does not calibrate “good”, then repeat the
above cleaning instructions. Do not clean more than 3 times in a
row. If the tonometer still will not calibrate, contact Reichert.
Note: Always store the TONO-PEN AVIA tonometer with an OCU-
FILM®tip cover installed to protect the tonometer tip from dirt
and contaminants.
Note: Never use the TONO-PEN AVIA tonometer without an OCU-
FILM®tip cover installed.
Cleaning Instructions
The TONO-PEN AVIA tonom-
eter may have difculty taking
measurements or display “bad”
after a calibration when its tip
is dirty and requires cleaning.
When the tip of the tonometer
has dirt and contaminants in the
airspace between the sensor
Quick Reference Guide
and the housing, cleaning of the tip is necessary. When the airspace
contains contaminants, the sensor cannot move freely and the tonom-
eter may have erratic readings and then show a “bad” calibration.
To clean the tonometer, perform the following steps:
1. Remove OCU-FILM®tip cover from the tonometer, if one is
installed.
2. Using canned air, place the sensor end of the tonometer against
the outlet of the canned air as shown above.
3. Blow the canned air into the tip of the tonometer for
approximately 3 seconds.
Note: It is necessary to blow canned air directly into the tip, so
that the contaminants are pushed out of the airspace between
the sensor and the housing.
