INTRODUCTION

Thank you for purchasing the TOPCON Computer­ized Tonometer CT-80.

(To get the best use from the instrument, please carefully
read these instructions and keep this Instruction Manual in a
convenient location for future reference.)

This instrument features the following:

• An exact, non-contact intraocular pressure measurement that
can be done by air ejection.

• An alignment bar that enables easy operation.

This text outlines the Computerized Tonometer CT-80 and de­scribes basic operations, troubleshooting, checking, maintenance
and cleaning.
To encourage the safe, efficient use of this instrument and prevent
danger to the operator and others, we suggest you carefully read
the “Displays for Safe Use” and the “Safety Cautions”.
Again, please keep this Instruction Manual in a convenient location
for future reference.

Precautions

•

This machine is a precision instrument; install it in a place set to the fol­lowing conditions: temperature (10∼60°C), humidity (30∼85%) and atmos­pheric pressure (70∼106KPa). Avoid direct exposure to sunlight.

To ensure smooth operation, install the instrument on a level place free of

•

vibrations. Also, do not place any objects on the instrument.

Before using the instrument, connect all cables correctly.

•

Use the specified source voltage.

•

When not in use, turn the power off and put the measuring window cap and

•

dust cover on.

To ensure a correct reading, do not soil the measuring window with finger

•

prints, dust, etc. Also, do not touch the measuring nozzle except when
cleaning.

SAFETY CAUTIONS

WARNING

Icons Prevention item Page

To avoid electrical shock, do not open the instrument.
Refer all servicing to qualified personnel.

To avoid electric shocks, do not remove the covers from the bottom
and top surfaces, TV monitor, measuring unit, etc.

To prevent shock hazard, do not allow water or other foreign matter
to enter into the instrument.

To avoid fire and electric shocks in case of tumbling, do not place a
cup or vessel containing water/fluid on the instrument.

To avoid electric shocks, do not insert objects or metals through the
vent holes or gaps or contain them inside the machine body.

To avoid electrical shock and fire, unplug the power cable before
removing the fuse cover. Additionally, be sure to replace the fuse
cover before plugging in the power cable.

Use only the attached fuses. Using other fuses may cause a fire.

Should any anomaly, such as smoke, occur, immediately switch
OFF the power source and unplug the power cable.
Continued use ignoring the condition may cause fire. Contact your
dealer for repair.

SAFETY CAUTIONS

CAUTION

Icon Prevention item Page

To avoid potential injury, hold the instrument in the proper position.

To avoid electrical shock, do not handle the power plug with wet
fingers.

Never insert your fingers under the measuring head.
∗ Inform the patient of this, too.
Careless insertion of fingers may cause injury by pinching.

Never insert your fingers under the measuring head.
∗ Inform the patient of this, too.
Careless insertion of fingers may cause injury by pinching.

Do not use or apply any spray-typed cleaner near the instrument.
If a drop of cleaner remains inside the measuring nozzle, the pa­tient’s eye may be injured during measurement.

Before carrying the instrument, be sure to affix it firmly by turning
the fixing screw at the base.
If the instrument is moved with the screw loosened, it may result in
damage to the instrument.

When moving the instrument, be sure to hold it at the bottom sur­face with two people. Carrying by one person may cause back inju­ry or injury by falling parts. Also, holding areas other than the bot­tom surface may cause pinching fingers between parts and injury
by falling parts as well as damage to the instrument.

Before measuring, set the safety stopper. If the safety stopper is
not set, it may cause injury to the eye that comes in contact with the
measuring window glass. Set the safety stopper separately for the
right and left eyes.

When setting the safety stopper, do it from the instrument side
(safety stopper knob side).
Setting from another position does not easily allow you to check the
positions of the measuring window glass and the patient’s eye and
may cause injury to the eye that comes in contact with the measur­ing window glass.

To clean the measuring window glass and the window glass inside
the measuring nozzle, use ethanol. Using other chemicals may
cause damage to the patient's eye during measurement.

When the machine body needs to be moved slightly back and forth or right and left,

•

move the control lever in each direction.

It is recommended that you do intraocular pressure measure­ments several times. Since the intraocular pressure varies by
heart beats and tears, often it is not possible to obtain exact
measurement values by measuring only once or twice.

Operating the control lever

At this moment, be careful not to catch eyelashes and eyelids within the outer align­ment mark so as to ensure correct measurements.

If the instrument is too close to the target eye, with regard to the alignment reference
position, “TOO CLOSE” is displayed on the monitor screen, and if it is too far, “FOR­WARD” is displayed.
The alignment bar is displayed as a broken line when the instrument is close to the
target eye and as a solid line when it is far. Also, the alignment bar is shortened ac­cordingly as it approaches the alignment reference position.
These factors are displayed only when the alignment dot is near the inner alignment
mark.

HOW TO PRINT OUT MEASUREMENT VALUES

To avoid printer problems due to paper jams, do not feed paper

•

if it is torn or creased.

To avoid discoloring, particularly of the recording part, do not

•

store the printer paper in holders made of materials containing
plasticizers (ex., vinyl chloride).

MEMO

This machine can print out measurement values with the built-in printer.

Return to the Measurement screen.

1

Press on the control panel.

2

Measurement values of the monitor screen are printed out.
Upon printing, the measured values are deleted automatically from the screen.

To avoid coloring in the white part and discoloring in the re-

•

cording part, do not use bonds containing solvents. Use water
bonds.

The printer paper is heat sensitive and cannot keep records for

•

long periods of time. Copy the records to other paper for stor­age.

The ERR display is not printed. Also, printing can not be done when no measurement
values exist. When a red line appears in the printer paper, replace it. For details
about the replacement of paper, see “HOW TO SET PRINTER PAPER” on page 23.
Again, use the 58-mm wide TF50KS-E2C (Japan) paper for the printer.

When “PRINTER HEAD IS UP” is displayed, lower the paper retainer lever and press

again.
