Overview
The Reichert TONO-PEN XL is a precision electronic tonometer which measures
intraocular pressure (IOP). The body of the instrument is specially designed to t
comfortably in the user’s hand, facilitating fast and accurate measurements. The
stainless steel probe on the TONO-PEN XL contains a solid state strain gauge
which converts intraocular pressure (IOP) to an electrical signal. The probe tip
must be covered by a protective membrane. Reichert OCU-FILM® Tip Covers
are recommended. Utilizing a sophisticated “single chip” microprocessor and
electronics housed in the body of the instrument, the waveform produced by each
touch to the anesthetized corneal surface is analyzed and stored for a statistical
comparison process. Each single valid IOP reading is digitally displayed on the liquid
crystal display (LCD). When four valid readings are obtained, the mean IOP and the
standard deviation for those readings (an indication of reliability) are shown on the
LCD.
Intended Use
The TONO-PEN XL is intended for measuring IOP as a screening/monitoring tool for
Glaucoma or when increased IOP is suspected.

Calibration Procedure
The Tono Pen XL unit is internally calibrated, thus the instrument calibration should
be checked only before the rst use each day or in the event of unanticipated
readings. Calibration must be routinely and successfully performed once daily prior
to instrument use. Calibration should also be performed whenever it is indicated by
the LCD display, when batteries are replaced, or after an unsuccessful calibration. It
is not necessary to check calibration prior to each use:
Point the transducer end of the TONO-PEN straight down towards the oor
(see Figure 5a).
Depress the Operator’s Button two times rapidly. The time between the rst
and second button press must be between 0.5 and 1.5 seconds. The TONO-
PEN will “beep” and display [CAL].
Wait approximately 15 seconds for the TONO-PEN to “beep”. The display will
change from [CAL] to [UP].
Immediately (within 1 second) invert the TONO-PEN smoothly, pointing the
transducer end straight up (see Figure 5b).
A properly functioning TONO-PEN will display [Good] followed by a “beep”.
Repeat this Calibration Procedure if [bAd] is displayed.
After Good is displayed, depress the Operator’s Button one time and the
TONO-PEN will display [8.8.8.8], followed by a single row of dashes, [- - - -],
and then by a double row of dashes [====] followed by a “beep” tone, indicat-
ing the instrument is ready to measure IOP (Depressing the activation button
a second time will interrupt this process and send the unit to calibration
mode).

Calibration
Unsuccessful Calibration
If several consecutive attempts at checking the calibration are unsuccessful:
Loosen or remove the Ocu-Film Tip Cover from the TONO-PEN XL probe tip and
repeat the calibration check.
If still unsuccessful:
Spray the probe tip with compressed gas, and repeat the calibration check.
If still unsuccessful:
Replace the batteries and repeat the calibration check.
Note: If [CAL] appears followed by a row of four dashes [- - - -], the unit did not go into
calibration mode. To correct this, depress the button quicker two times or slower two
times (see step 2 of calibration procedure).
Note: Do not take measurements with the instrument if two consecutive [good] calibration
checks cannot be obtained. The instrument will not take a measurement when the prior
calibration check was [bAd].
Note: If the TONO-PEN XL fails to yield a [Good] calibration, call Reichert Technical
Service.

Page 13
Instrument Preparation
Prior to using the TONO-PEN XL for IOP measurement prepare the instrument
according to the instructions below:
Allow the instrument to thermally stabilize at room temperature (72-82° F, 22
- 28° C) for approximately 30 minutes prior to use.
Remove the Ocu-Film Tip Cover from the probe. Visually inspect the
tonometer’s probe tip for cracks, chips or other irregularities. If irregularities
are present, contact Reichert. Do not use the instrument.
If the probe tip passes a visual inspection, proceed.
To help prevent build-up of debris around the probe post, spray the probe tip
with compressed gas before the rst use of the day.
Cover the TONO-PEN XL probe tip with a new Ocu-Film Tip Cover. Reichert
Ocu-Film Tip Covers are:
• Individually wrapped and non-sterile sanitized
• For Single Use only
Perform daily routine calibration (See page 11)
Note: Calibration should only be performed on the TONO-PEN once daily, unless otherwise
indicated by the instrument. The TONO-PEN does not require calibration after every
patient examination.
CAUTION
Do not use the instrument without an Ocu-Film Tip Cover. Use without an Ocu-Film
Tip Cover will damage the instrument and void the Warranty.
Performing IOP Measurements
After the TONO-PEN XL has been prepared for operation, the patient must be
prepared and then IOP measurements can be performed.
CAUTION
Ocu-Film contains natural rubber LATEX which may cause allergic reactions.
Question patients about allergies to Latex before examining them with the TONO-
PEN XL.
To prepare a patient for an IOP measurement:
Instill a drop of topical anesthetic onto the eye to be examined.
Position the patient, seated or supine, in front of a xation target; or have the
patient xate on a point of reference (i.e. ear, nose, distant object) to minimize
eye movement.
Note: The TONO-PEN XL unit will function in any stable position.

Taking a Measurement

Page 14
To perform an IOP measurement:
Instruct the patient to look straight ahead at the xation target with his/her
eyes fully open.
Hold the TONO-PEN XL unit as you would a pencil.
Position yourself to facilitate viewing of the probe tip and patient’s cornea
where contact will be made. For normal corneas, central corneal contact is
recommended.
Brace the heel of your hand on the patient’s cheek for stability while holding
the TONO-PEN XL unit perpendicular to and within 1/2 inch of the patient’s
cornea. (See Figure 6 for correct positioning.)
To initiate an IOP measurement, depress the Operator’s Button once, and
only once.
Initially you will see a brief display of [8.8.8.8]. This is a self-test of the LCD
(Liquid Crystal Display). If any of the LCD segments are not displayed, the
TONO-PEN requires service.
If a momentary display of [CAL] is seen, followed immediately by a single row
of dashes [- - - -], it indicates that the TONO-PEN requires calibration before
it will measure.
If a double row of dashes [====] is seen and a “beep” tone is heard, it
indicates that the TONO-PEN is ready to measure IOP. Proceed with
applanation within 15 seconds.
Note: After acquiring the double row of dashes [====], if more than 15
seconds elapses prior to applanation, the TONO-PEN will not measure. The
software will have initiated a battery-saving function, indicated initially by the
display of a single row of dashes [- - - -], then followed in sequence by a blank
display [ ]. A new IOP measurement can be initiated by depressing the
operator’s button once.

Page 15
Note: Anytime the operator’s button is depressed twice within 1.5 seconds, (which
may be caused by operator’s inadvertent pressure on the button) the software will
interpret this as a demand for calibration. Then a sustained display of [CAL] will be
seen which initiates the calibration sequence. The calibration sequence must be
successfully completed before further measurements can be accomplished.
Once activated, after [====] is displayed and a “beep” tone is heard, touch the
TONO-PEN XL unit to the cornea lightly and briey, then withdraw. Repeat
several times. The corneal surface needs only to be momentarily contacted;
indentation is not required and may lead to inaccurate readings.
A chirp will sound and a digital IOP measurement will be displayed each time
a valid reading is obtained. The single horizontal bar at the bottom of the
LCD, indicating statistical reliability, will not be displayed with each single IOP
measurement.
After four (4) valid readings are obtained, a nal beep will sound and the
averaged measurement will appear on the LCD along with the single bar
denoting statistical reliability.
Note: If a single row of dashes [- - - -] appears on the LCD after the nal beep, an
insufcient number of valid readings was collected. If this occurs, repeat the
patient examination procedure, starting at step 1.
To take another measurement, reactivate the TONO-PEN XL unit by pressing
and releasing the activation switch as described in step 5.
Note: If not reactivated within 25 seconds, the TONO-PEN XL unit will automatically
turn off and the LCD will clear, placing the device in sleep mode, to conserve
battery life. If this occurs, activate the Tono Pen XL by pressing the Operator’s
Button once.
Replace the Ocu-Film Tip Cover before using the TONO-PEN XL unit on
another patient and before storage.
Note: Failure to replace the Ocu-Film Tip Cover between patients may result
in unreliable readings of IOP by allowing debris to enter the transducer
assembly.
Note: A reused Ocu-Film Tip Cover may leak. This may cause damage to the strain
gauge and void the Warranty.

Taking a Measurement

Page 16
The number display represents IOP in millimeters of mercury (mmHg.) A number with
a single horizontal bar displayed at the bottom of the LCD is an average of the valid
measurements. A number without the single bar is a single measurement of IOP.
(See Figure 7).
The display of one of four horizontal bars
located along the lower border of the LCD
block indicates the statistical reliability of the
averaged measurement. For example, if the 5%
bar is displayed, the standard deviation of the
valid measurements is 5% or less of the number
shown.
If the reliability measure is 20% or > 20%, a
repeat measurement is recommended.
A single row of dashes [- - - -] indicates that the
instrument is activated.
Two rows of dashes [====] followed by a “beep”
indicates that the instrument is ready to take
measurements.
“CAL” indicates that the instrument is in the
process of calibration check or the instrument
needs to undergo calibration check procedure.
If “CAL” is displayed following a long beep and
“- - - -”, the latter is the case. A “Good” calibration
check must be obtained.
“Lob” indicates the need to replace both batteries prior
to using the instrument.
“UP” indicates that the instrument is being calibrated and the probe tip should be
turned from pointing down to pointing up.
“Good” indicates the calibration check procedure was successful. After two “Good”
calibration checks, the TONO-PEN XL unit is ready for use in patient examinations.
“bAd” indicates the calibration check procedure was unsuccessful and must be
repeated.

Avoid any shock or excessive vibration which will damage the unit. Clean with a non-
abrasive, dry cloth.
CAUTION
DO NOT IMMERSE TONO-PEN XL BODY IN FLUIDS. THIS WILL CAUSE DAMAGE TO
THE ELECTRONICS AND VOID THE WARRANTY.
Battery Replacement
The batteries need replacing when multiple beeps sound and “Lob” appears on the
LCD upon depressing the activation switch. Occasionally, a noticeable slowing in the
calibration check process or in activating the instrument for taking measurements
may suggest that the batteries need replacing. Always replace both batteries. Do not
mix used and new batteries in the instrument. Reichert OCU-CEL XL batteries are
recommended.
