1 Application and description
The OS3 operating unit is used in surgical procedures to the
anterior and posterior segments of the eye. It performs all
essential functions including irrigation and aspiration,
ultrasound Phaco, bipolar diathermy for haemostasis and
coaptation of conjunctiva, diathermic capsulotomy, diathermic
tissue cutting and the drive of vitrectomy instruments. The
unit can be supplemented with the VC830200 module for
carrying out vitreo-retinal procedures.
The unit actuates and controls companion instrumentation
within the performance limits chosen by the operator and as
set on the control panel. A foot pedal effects fine adjustments
within the pre-set limits. The unit is extremely easy to use.
Frequently used equipment settings can be stored and
recalled.
The unit may only be used with the Oertli instruments
recommended and supplied by the manufacturer (see
Section 13).
The unit may only be operated by trained personal. Correct
settings are the responsibility of the surgeon.
The unit is not suitable for surgical procedures outside the
eye. If in doubt, contact the manufacturer.
2 Points to note and hazards
IMPORTANT
Please read these instructions very carefully before using the
apparatus for the first time!
IMPORTANT!
Before connecting the unit, check that the voltage shown on
the rating plate is the same as that of the operating room!
IMPORTANT!
1. Patients with heart pacemakers or pacemaker electrodes
may be at risk in that the functioning of the pacemaker may
be impaired or the pacemaker itself damaged. If in doubt, the
cardiology department must be consulted.
2. The functioning of other electro-medical equipment may be
affected during the operation of bipolar diathermy,
capsulotomy and vitrectomy cutters.
IMPORTANT!
Where high-frequency diathermy, HF-cut or vitreous cutting is
used simultaneously with physiological monitoring equipment
on the same patient, any monitoring electrodes must be
placed as far as possible from the diathermy points. Needle
monitoring electrodes are not recommended. Monitoring
systems incorporating high-frequency current limiting devices
are recommended in all cases.
IMPORTANT!
The correct choice of instrument settings is the responsibility
of the surgeon! Values given in this instruction manual are
suggestions only.
IMPORTANT!
Only instruments and accessories supplied by the
manufacturer and listed in Section 13 may be used!
IMPORTANT!
Only persons authorised by the manufacturer may carry out
modifications and repairs, otherwise the proper functioning of
the unit may be impaired.
IMPORTANT!
While operating in diathermy or HF-cut mode, the instrument
tip must be monitored carefully. The pedal must be released
immediately as soon as tissue begins to overheat
excessively.
IMPORTANT!
All accessories must be checked regularly! Diathermy cables
in particular should be checked for possible damage to the
insulation.
IMPORTANT!
The unit must never be used in areas containing inflammable
anaesthetics!
IMPORTANT!
The cart with the tray fully stretched out can tip over if

3 Control panel
All settings for the operation of the OS3 operating unit can be
undertaken using the control panel (pre-settings are made
using ParaProg. See Section 10). Visual displays serve to
show the current operating state of the unit and the current
values. The buttons respond to light pressure, which can also
be applied using a sterile swab or the special sterile operating
pen (VE850003) available from the manufacturer.
Depending on the stage of the operation or the setting of the
operating pedal, certain buttons will be blocked. This feature
offers increased protection against improper use.
The execution of a button command is accompanied by
corresponding changes in the display field. There is no
change in the display when a blocked button is pressed.
The control panel can be separated from the unit and placed
in a sterile bag for use in the sterile area. To do so, lift and
disengage the control panel from below. Alternatively, an
additional control panel VE 830025 or a remote controller VE
830020 can be connected to socket M3.
3.1 Arrangement of control and indicator elements
The controls and displays are grouped in such a way that the
unit can be operated after just a short familia- rization period,
even in semi-darkness. The top half of the control panel is the
display and adjustment area for the phaco, vitrectomy,
diathermy and capsulotomy functions. It shows at a glance
the operating state of the unit and the current values. The
values displayed can be increased or decreased using the
dark green arrow buttons immediately beneath the display.
The lower half of the control panel houses the displays and
adjustment buttons for the irrigation/aspiration system.
The lowest row on the control panel contains all the buttons
for the auxiliary functions.
Please familiarise yourself thoroughly with this ergonomic
arrangement of the control elements; it will quickly enable you
to operate the unit almost "blind"!

signals (SOUND) and voice messages (VOICE). Also adjusts
the IOP indicator (bottle height).
VOICE button
Repeats or stops the current voice message. The scope of
information given can be defined in ParaProg.
PREOP button
Initiates the filling and rinsing function, and stops the
procedure if pressed again. Completes the procedure with a
phaco test if PREOP is started when in phaco 1, 2, 3
operating mode.
TEST button
Starts the phaco test when the unit is set to phaco 1, 2 or 3,
or activates the connected vitrectomy instrument during
button depression, if the unit is in VIT A, VIT B or VIT PN
mode.
NOTE: If not willingly activated PREOP or Phacotest also
can be interrupted by pressing pedal with the heel.
Then the display shows the message “PREOP
discontinued” or “Phaco Test discontinued”.
4 Control pedal
The control panel is used to regulate the I/A system and all
instruments. It must be connected to the pedal connection
socket (M1) on the rear of the unit. The control pedal can be
moved vertically (downwards) and
horizontally (sideways) and has four switching elements,
which, for safety reasons, can only be accessed by lifting the
foot.
The vertical plane
Fig. 1
The vertical range – from zero to the fully depressed position
– is divided into a maximum of three ranges: irrigation,
aspiration and instrument activation. These three ranges lie
between positions 0, 1, 2 and 3. If the pedal is pressed
slowly, the settings 0-3 can be felt as a slight resistance. This
resistance can be changed in ParaProg (low, medium, high).
The pedal is brought to position 4 by pressing with the heel,
and this position is always used to activate reflux.
The number of positions and the amount of travel between
them can be changed in ParaProg. This is described in detail
in the ParaProg user manual, VV016013E.
The vacuum is always off in position 0.There is no suction,
and the instruments are inactive.
The service engineer can adjust the firmness of the pedal
(resistance to movement).
The horizontal plane
In the horizontal plane, the pedal can be moved to the left
and right. The pedal can be moved horizontally from any of
the vertical positions, i.e. even when the pedal is depressed.
If duallinear operation is selected in ParaProg (see Section
10), the chosen instrument is controlled linearly by moving
the pedal to the left (i.e. the power of the instrument
changes in proportion to the deflection).
Moving the pedal to the right switches between the
multimode memories of the function just used (e.g. phaco 1-
2-3 etc.).
ParaProg (see Section 10) can be used to specify whether 2
or 3 memories should be available.
Switching elements
The two round switches (heel switches) can be operated with
the heel (the pedal does not have to be in the zero position)
to change the infusion pressure (bottle height) or air pump
pressure. Pressure is always reduced with the left heel
switch, and increased with the right heel switch.
The two switches on the pedal grip (TOP switch) are
positioned so that they can only be activated after the pedal
has been returned to the zero position (foot raised).
TOP left
Switches between the basic functions (selector) e.g. I/A,
CAPS, Phaco, etc. Each surgeon can enter his preferred
sequence in ParaProg.
In ParaProg (se Section 10) you can invert the assignments
of left and right of the horizontal movement to right and left.

5 Mains connection / switching the unit on/off
IMPORTANT!
The mains voltage in the operating area must be
100...240VAC / 50...60Hz!
Plug the supplied mains cable into the mains connection
socket O on the back of the unit, and connect to the mains
supply socket.
Move the power switch Q to position I.
As soon as it is switched on, the unit starts a self test
(AUTOTEST), and checks the functioning of the switching
circuits, voltages, tone generation, instrument drives and
pump.
If the pedal is not connected, the message "NO PEDAL"
appears.
When the test has been completed successfully, the
message "SELECT SURGEON" is displayed.
The selected surgeon memory appears in the surgeon
display. It can be changed by using the arrow buttons.
In the flow display, the version of the installed software
appears in weakly illuminated lettering.
The unit is now ready and can be prepared for the operation.
5.1 Replacing fuses
Press the clip on fuse holder P to the right, until it pops out.
Use a small screw driver as desired. Fully pull out holder.
Insert new fuses and push in the holder P again.
The correct fuse value is printed above the holder P on the
rear panel of the unit.
6 Setting up the I/A system
With the exception of diathermy and capsulotomy, a properly
set up and filled irrigation/aspiration system is essential for all
operations.
IMPORTANT!
To ensure trouble-free operation, the I/A system must be
completely filled with irrigation fluid. The tubes must be
completely free of air bubbles!
The OS3 unit cassette system simplifies the proper set-up of
the I/A unit. Three different designs are available.

Autoclavable cassettes must be cleaned and sterilised
according to the instructions on the packaging insert. After
multiple sterilisation processes, the cassettes and tubes will
show signs of ageing which will endanger the proper
functioning of the I/A system and may result in damage to the
unit due to the ingression of water.
IMPORTANT!
Reusable cassette sets must be replaced after 10 sterilisation
cycles!
IMPORTANT!
Single-use cassette sets must never be reused!
IMPORTANT!
Reusable cassettes must be clean and free from remnants of
silicone or visco substances, inside and outside, to avoid
false alarm of the liquid level indicator.
6.1 Installing the cassette
IMPORTANT!
Ensure that conditions are sterile when installing the tubing
system!
The ends of the instrument connection tubes must be kept in
the sterile area. The sterile person must not insert the tubes
into the unit!
Turn the cassette rotary switch in an anti-clockwise
direction and open the cassette door G1 downwards.
IMPORTANT!
Do not reach into the cassette opening (risk of injury!) Never
insert any kind of tool into the cassette opening (risk of
damage!)
Insert the cassette in the cassette opening (with the
tubes facing the operator). Lightly bend the tubes to the
right with the right hand, and use the left hand to close
the cassette door by pushing it upwards. Turn the
cassette rotary switch G in a clockwise direction until you
hear and feel it engage (horizontal position). The
cassette is now fully connected to the pump system.
The tubes must not be kinked nor trapped in the cassette
door!
Remove the protective cap 3a, and mount on emergency
discharge 4, then connect BSS connector 3 with the
giving set. Ensure sterility.
Note: Alternatively, the giving set can be attached to connector 3 in the sterile
area before the cassette is installed.
Check that cap 4 for emergency discharge and screw
cap 6 for emptying the cassette (autoclavable cassette
only) are screwed tightly shut.
The Ultrasound time will be reset after installation of the
cassette.

29.05.09 VV016011E 10
6.2 Filling the I/A system (PREOP)
To fill the I/A system, the instrument ends of the connection
tubes should be prepared as follows in the sterile area,
ensuring that sterile conditions are maintained:
Variant 1
Connect to a phaco handpiece and set up a phaco test
chamber (VV803100).
This procedure is described in detail in Section 7.2.
"Ultrasonic phaco handpiece".
Test chamber

Variant 2
Connect to a I/A instrument and insert the point of the
instrument in a container of infusion liquid.
This procedure is described in detail in Section 7.1.
"I/A instrument".
I/A tip
I/A handpiece
Variant 3
Immerse the loose ends in a container of infusion liquid or
join together the infusion and aspiration tubes.
Variant 1 is recommended so that a phaco test can also be
carried out.
Prepare the instrument tubes in accordance with one of
the above variants.
Open the infusion tap on the giving set and press the
PREOP button.1) The message of "FILL RINSE" will
appear in the display and the progress of the filling
procedure is indicated in %.
As soon as the entire tubing system is completely filled
with fluid, and no more bubbles are visible, the filling
process can be stopped by pressing the PREOP button
again. However, the filling process automatically
switches itself off approx. 55 seconds.
The I/A and phaco system is now ready to use.
If variant 1 is being used, press PHACO 1, 2 or 3 first, then the PREOP button.
The phaco test will then be carried out automatically when the filling process is
complete.
NOTE: The PREOP function is divided into two phases: I Filling of the infusion

I/A2, PHACO1, VIT A etc.) and hold down for a short period.
The message "SETTING VALUES" appears, accompanied
by an acoustic signal, and finally the message "VALUES
SET". The new values are now stored and can be recalled at
any time. If you release the button too soon, the message
"VALUES NOT SET" will appear.
* The PULSE or BURST function is not stored if
"PULSMODE NO" is set in ParaProg (see chapter 10).
* Continuous irrigation is also stored for each of the
functions I/A, PHACO and VIT. Continuous irrigation is
not stored for all other functions
Note that values for peristaltic and venturi operation must be
stored separately, which also means that different values can
be stored.
Section 8.3.4 describes the procedure for storing values for
Occlusion Mode Phaco.

8.2.1 I/A operation
Press the I/A 1, 2 or 3 button.
I/A1 SURGEON 2
IOP 65cm
15 ml/min 350mmHg
The display fields show the selected function together with
the active surgeon memory and any relevant limit values
stored for flow and suction. Using the arrow buttons, these
values can be increased or reduced at any time within the
ranges 0 to 50 ml/min (0 to 100%
VENT) or 0 to 600 mmHg. See Section 8.1 for information
about storing values.
The irrigation / aspiration procedure is controlled by the
surgeon using the pedal. When the pedal is operated, the
current values will appear in the display fields.
To exit the I/A function, you can either press a new function
button or the RESET button.
As long as the pedal is being operated (except when in
position 1), all the buttons – with the exception of the arrow
buttons, I/A 1, I/A 2, IRR, AUX, VOICE and RESET – remain
blocked.
8.2.2 Changing between venturi/peristaltic operation
If cassettes VV 630003 or VV 630010 are being used, you
can change between the venturi and peristaltic pump at any
time. To do so, the pedal must be in the zero position.
Effect the change by pressing the venturi button on the
control panel (or remote controller), or the right TOP switch,
on the pedal grip.
Venturi operation is shown by the green indicator light next to
the venturi button and by the %VENT display.

IOP 65cm
70% VENT 150mmHg
Note: In ParaProg you can specify per surgeon and per function whether you
wish to work with peristaltic only, venturi only, or with both pumps.
8.2.3 Infusion pressure IOP
8.2.3.1 Gravity infusion with bottle height
When using the OS3 infusion trolley VE830001, the height of
the infusion bottle can be adjusted with both the heel buttons
on the pedal and the arrow buttons beneath the IOP display.
The display indicates the height of the bottle above the
patient's eye in cm.
Proceed as follows to calibrate the bottle height: measure or
estimate the bottle height, hold down the AUX button and
enter the measured value using the arrow buttons beneath
the IOP display. Release the AUX button.
The maximum bottle height can be defined in ParaProg. To
do so, position the bottle at the chosen maximum height,
open ParaProg (see Section 10) and answer Fluidics-More-
SET POLE LIMIT with YES.
NOTE: In ParaProg you can set surgeon-specifically whether the HEEL buttons
on the pedal are activated/deactivated.
8.2.3.2 Active infusion with air pump
When using the Vitrex VC830200 extension module, the air
pump can be used to produce pressure in the infusion bottle.
Follow the instructions in the leaflet accompanying the active
infusion set.
The IOP button must be pressed on the Vitrex module. The
IOP display will show the bottle pressure in mmHg, which can
be changed using the HEEL buttons and arrow buttons
beneath the IOP display.

29.05.09 VV016011E 14
8.2.4 Continuous irrigation
Press the IRR button if irrigation flow is to be maintained
independently of the pedal position. An active IRR function is
indicated by the falling droplet symbol in the function display.
Pressing the IRR button again will switch off the IRR function.
Irrigation flow begins as soon as the pedal is moved to
position 1 for the first time. It can be stopped by moving the
pedal back to position 4.
NOTE: The Parameter „IRR OFF BACKWARDS YES NO“ of the ParaProg
disables or enables the function of stopping the continuos irrigation by moving
the pedal backward to position 4.
The IRR function can be used in conjunction with all the other
functions. If the IRR button is held down, the irrigation valve
opens.
8.2.5 Reflux
Reflux (backflushing) is actuated by moving the pedal
backward into position 4 (Fig. 2), or if selected in ParaProg by
switching to the left. Unless otherwise specified in ParaProg,
reflux is effected by the reverse operation of the pump. The
Twin Vac cassette is designed to exclude any possibility of
contamination. The maximum reflux pressure with the pump
is 150 mmHg (Venturi) or 250 mmHg (peristaltic).
NOTE: In ParaProg, the duration of reflux (REFLIMIT) can be limited to 2
seconds per activation, and instead of reversing the pumping action, you can
opt to effect reflux using inflow from the bottle.
8.2.6 Proportional Override
To override the vacuum limit in pedal position 3, a higher
upper limit value of up to 600 mmHg may be entered using
the OOC-M button.
To do this, keep the OC-M button depressed in the I/A1, I/A2
or I/A3 program (possible individually) and set the desired
upper limit value using the arrow key beneath the vacuum
display. This value should be higher than the I/A limit value. If
an override value was chosen, then this will be indicated in
the I/A function by the OCC-M indicator light. Active override
is indicated by flashing of the word “Override” and by an
acoustic signal. The override value will remain stored. If the
override function is not wanted, reduce the vacuum, using
the arrow key whilst the OCC-M button is depressed, until the
word “OFF” appears.
8.3 Ultrasonic phaco
The unit is set to phaco mode by actuating one of the buttons
PHACO1, PHACO2 or PHACO3. The function selected is
shown on the display panel with the corresponding pre-stored
values.
8.3.1 Phaco test
The handpiece must be tested before beginning the
operation. To do so, fit a filled test chamber to the handpiece
and press the TEST button.
Never carry out the TEST procedure whilst the handpiece is
in the eye!
NOTE: The test will already have been carried out automatically if PREOP was
started from PHACO1, 2 or 3.
Once the test is complete, one of the following messages will
appear:
“PHACO TEST OK” (for 2 seconds)
The phaco system is ready for use.
“CONNECT HANDPIECE!”
The handpiece is not connected.
“CHECK HANDPIECE”
The handpiece is faulty or worn out. Repeat the test! If the
same message appears, use another handpiece and contact
the service centre. By pressing the TEST button again you
can acknowledge the message and, if necessary, continue
working with the handpiece, but its performance will be below
standard.
“HANDPIECE DEFECTIVE”
The handpiece is defective, and should no longer be used.
Use another handpiece and send the faulty handpiece to the
service centre.
“CHECK TIP”
The tip is not properly attached or an Oertli original tip is not
being used. Tighten the tip and repeat the test. If the same
message appears, use another tip.
NOTE: The phaco test can be aborted by pressing the TEST button. The
phaco test can only be started when the pedal is in its zero position.
8.3.2 Phaco operation
Once the test function has been completed successfully, the
unit will be in the last selected function: PHACO1, PHACO2
or PHACO3.
PHACO1 70% 2s SURGEON 2
IOP 65cm
20ml/min 180mmHg
The display fields will show the selected function and the
corresponding stored limit values for phaco power, flow rate
(venturi speed) and suction. These values can be reduced or
increased at any time using the arrow buttons. The ranges
are 0-100%, 0-50 ml/min or
0-100%VENT and 0-600 mmHg (0-300 mmHg for Venturi).
Section 8.1 describes the procedure for storing values.
The surgeon uses the pedal to control the phaco handpiece.
The pedal functions are described in Section 4. When the
pedal is being used, the current values will be shown in the
value display fields. The phaco time display will run for as
long as there is phaco operation.
If Phaco LINEAR has been selected in ParaProg, delivery of
phaco power is proportional (linear) to the pedal deflection.
If Phaco PANEL has been selected in ParaProg, power is
delivered in pedal position 3 with the value selected by the
arrow keys. The value indicator on the panel blinks.
To quit the PHACO function, you can either press a new
function button or the RESET button.
As long as the pedal is being operated (except when it is in
position 1), all the buttons – with the exception of the arrow

29.05.09 VV016011E 15
buttons, PHACO1, PHACO 2, PHACO3, PULSE, IRR, AUX,
VOICE and RESET – will remain blocked.
8.3.3 Phaco pulse and phaco burst
The pulse or burst function is switched on and off by pressing
the PULSE button or by moving the pedal to the left (if linear
phaco with PULSMODE is selected in ParaProg). Changing
between pulse and burst is done by repeated pressing of the
PULSE button.
Pulse
In the pulse function, phaco output is given in short pulses.
The number of pulses per second (pulse frequency) can be
selected between 0.5 and 40. To do this, press the PULSE
button and hold it down while you set the chosen values
using the arrow buttons beneath the value display. The pulse
frequency as selected by each surgeon remains stored, even
when the unit is switched off.
The cooling factor can be specified while keeping the
PULSE button from 10% to 99% in 1% increments or in 10%
increments.
Burst
In the burst function, phaco output is given in short pulses
(bursts). The number of bursts per second is (frequency)
proportionally controlled by the pedal, from a single burst
(0.5Hz) up to continuous power delivery To do this, hold the
PULSE button down and set MAX PEDAL accordingly. The
phaco power always corresponds to the value selected with
the arrow key on the panel (1% to 100%), irrespective of
pedal position.
NOTE: If Phaco PANEL has been selected in the ParaProg, only one single
burst with the selected values is delivered in pedal position 3. The next burst
will be released only after the pedal has been brought back to position 2.
The burst duration
(duration of phaco power delivery) can be selected from
10ms to 500ms. To do this, press the PULSE button and hold
it down while you set the chosen value using the arrow
buttons beneath the value display. The burst length as
selected by each surgeon remains stored, even after the unit
is switched off.
NOTE: If PULSMODE was selected in ParaProg (pulse or burst switched on by
moving the pedal horizontally), pulse or burst will not be stored as a part of
PHACO1, 2 and 3. Otherwise, pulse will also be stored.
8.3.4 CMP Phaco
Press the CMP button to switch the CMP function on and off.
In the CMP function phaco power is delivered in short pulses.
The pulse frequency and the cooling factor can be selected
as desired within the limits set by the machine. To do so hold
the CMP button down and select the values with the arrow
keys. Independent of the values selected the phaco tip will
remain cool, even at 100% phaco power. This allows
operations without infusion sleeve. The phaco power is
always proportional to the pedal deflection.
Note: CMP1, 2, 3 have their own memories. By holding down the
corresponding button phaco 1, 2, 3 (see 8.1) for a short period, all settings will
be memorized.
8.3.5 Occlusion Mode Phaco
In occlusion mode, the unit operates until a freely-definable
vacuum limit is reached (occlusion vacuum) with the values
stored in PHACO1, PHACO2 or PHACO3 (or CMP1, CMP2,
CMP3) and above with the values of the respective OCC-M
memory. When the occlusion vacuum is reached, the unit
switches to the OCC-M values for flow (venturi), phaco output
and pulse. Example:
PHACO1 OCC-M 1
Vacuum 200mmHg a) 150mmHG b)
Flow 15ml/min 25ml/min
Power 70% 50%
Pulse or burst Off On
a) Maximum vacuum, is never exceeded
b) Occlusion vacuum. When this has been reached, the unit switches to the
OCC-M values.
Must be lower than vacuum a).
Switching on the OCC-M
To switch on and off, press the OCC-M button lightly. The
OCC-M is ready when the LED lights up. As soon as the
occlusion vacuum is reached in the course of the operation,
the LED begins to flash rapidly. The OCC-M values are now
active.
Storing the OCC-M values
First store the multimode values for PHACO1, PHACO2 and
PHACO 3 (or CMP1, CMP2, CMP3) as described in Section
8.1. Then call up the memory to be programmed.
Fully depress the OCC-M button. The LED will flash slowly.
The displays will show the values for the OCC-M.
Using the arrow buttons, firstly set the chosen value for the
occlusion vacuum. It must be lower than the vacuum in the
respective multimode memory. Higher values will not be
accepted.
Next, set the values for flow (venturi speed) and phaco
power, and switch PULSE or BURST on or off (not possible
in CMP).
Hold down the PHACO 1 (or PHACO2 or PHACO3) button as
described in 8.1. When "VALUES SET" appears, fully
depress the OCC-M button again. The LED extinguishes.
Repeat the procedure for the other multimode memories
(PHACO2, 3 etc.).
NOTE: The OCC-M function can only be switched on and off when the pedal is
in the zero position or position 1.
8.3.6 Proportional override for Phaco
To override the vacuum limit value in pedal position 3
through moving to the right, a higher limit value up to
600 mmHG can be inputted using the OOC-M button.
First save the multimode values for PHACO1, PHACO2
and PHACO3 (or CMP1, CMP2, CMP3) as described
in chapter 8.1.
Then, in the program PHACO1, PHACO2, or PHACO3
(possible individually), press hard on the OCC-M button
and change OCCM-SET to OVERRIDE using the arrow
button beneath the IOP display. Then, using the arrow
button beneath the vacuum display, set the upper limit
value. It should be higher than the PHACO limit value.
Then end the setting procedure by pressing hard on
the OCC-M button. That fact that override is active is
indicated by the blinking of the word OVERRIDE and

29.05.09 VV016011E 16
with an acoustic signal. The override value will remain
stored. If the override function is not desired, press
strongly on the OCC-M button and change OCCM-SET
to OVERRIDE using the arrow button beneath the IOP
display. Then lower the vacuum value using the arrow
button under the vacuum display until OFF appears.
8.3.7 Setting of values for additional aspiration and
Phaco power in DUALLINEAR 2 mode
If you have decided for left movement of pedal for
DUALLINEAR 2 in ParaProg you can chose either the value
for additional aspiration or Phaco power with the OCC-M
button. Press the button and hold it until you can select the
value for ASP or Phaco dependant on the settings made in
ParaProg.
8.4 Diathermy
Press the DIA button.
DIA 40% SURGEON 2
IOP 65cm
The chosen function appears in the display fields with the
output value last used. The output value can be increased or
reduced at any time with the arrow buttons. The range is 0-
100%, unless otherwise specified in ParaProg. Two separate
limit values for "DiaLimit LOW" and "DiaLimit HIGH" can be
programmed in ParaProg.
The surgeon controls the diathermy output by using the
pedal. Unless otherwise specified in ParaProg, the following
functions are available:
Horizontal movement leftwards: linear control to maximum
LOW value
Horizontal movement rightwards: linear control to maximum
HIGH value
Vertical movement to position 2: linear control to maximum
LOW value.
ParaProg can be used to specify whether linear control to the
maximum HIGH value should be possible in position 3, and
horizontal control to right and left are switched off separately.
The I/A function cannot be used when the unit is in the
Diathermy setting. However, ParaProg can determine
whether irrigation should flow in position 1.
To exit the DIA function, you can either press a new function
button or the RESET button.
As long as the pedal is being operated, all the buttons – with
the exception of the arrow buttons, RESET, AUX, VOICE and
PREOP – will remain blocked.
Instant diathermy
By moving the pedal horizontally to the left (while it is in
position 0), the diathermy function remains available without
having to set the unit to diathermy mode by pressing the DIA
button.
This function can be set to DiaLOW or DiaHIGH or switched
off in ParaProg.
NOTE: ParaProg can be used to determine whether "Instant Diathermy" should
be available in all pedal positions when the unit is in VIT A, VIT B, VIT PN.
8.5 HF CUT
Press the HF cut button.
The chosen HF CUT function appears in the display fields
together with the application last used CAPSULE or
GLAUCOMA. With the arrow keys you can switch between
CAPSULE and GLAUCOMA.
8.5.1 Capsulotomy
Select HF CUT and subsequently CAPSULE: With the arrow
keys you can switch between the power ranges REGULAR
(recommended) and HIGH (for capsulotomies underneath the
iris). Power is controlled by the unit itself and cannot be
influenced by the surgeon.
The surgeon actuates capsulotomy operation by using the
pedal. Unless otherwise specified in ParaProg, the following
controls are available:
Horizontal left movement:
REGULAR output
Horizontal right movement:
HIGH output
Only if HIGH was first selected with the arrow button.
Vertical position 1:
REGULAR output.1)
NOTE: ParaProg can be used to specify whether HIGH output should be
available in position 2 and whether horizontal control to the right and left can be
switched off separately.
1) Unless HIGH was selected using the arrow button. The setting last used as
by each surgeon remains stored, even after the machine is switched off.
As long as the unit remains in CAPS mode, the I/A system
cannot be operated. An activated IRR function will be
retained however.
To exit CAPS, you can either press a new function button or
the RESET button.
As long as the pedal is operated, all buttons – with the
exception of the arrow buttons, RESET, AUX, VOICE and
PREOP – will remain blocked.

Press one of the buttons VIT A, VIT B or VIT PN.
VIT A1 1200/min Surgeon 2
IOP 75cm
10ml/min 250mmHg
The display fields indicate the function selected, together with
the values last used for cutting rate, flow (Venturi rate) and
suction. The arrow buttons can be used to increase or reduce
these values at any time.
Unless otherwise specified in ParaProg, the VIT A connection
serves to operate an SDS or SUS guillotine vitrectomy
stripper, and the VIT B connection the micro-scissors.
The PN connection is for operating the pneumatically-driven
Twinac vitrectomy instrument.
NOTE: In ParaProg, VIT A, VIT B and VIT PN can be set up for stripper or
scissor operation, according to preference.
Vitrectomy multimodulation programs
Three multimode memories are available for each of the
functions VIT A, VIT B, VIT PN. They are identified as VIT
A1, VIT A2, etc. on the function display. Switching between
these multimode programs is accomplished by repeated
depressing of the corresponding function key (VIT A, VIT B,
VIT PN) or by swinging the pedal to the right while in position
0 or 1.
NOTE: in ParaProg you can barr these multimode memories or limit to two
memories only.
Storing of the values for the vitrectomy multimode programs
is done as described in Section 8.1.
TEST function
Press the TEST button to check whether the connected
instrument is functioning properly (operation with the set
number of cutting movements).
The surgeon controls the vitrectomy procedure by using the
pedal. When the pedal is active, the value display fields show
the current values. Unless otherwise specified in ParaProg,
the following controls are available ("linear vitrectomy"):
Vertical step 1: Irrigation
Vertical step 2: Linear aspiration
Vertical step 3: Linear cutting
Horizontal left: Instant diathermy (only in position 0)
Horizontal right: Single cut (stripper VIT A) Close scissors
(VIT B)
NOTE: In ParaProg, you can specify the reverse sequence: position 2 cut,
position 3 aspiration, and program the horizontal right movement to switch
between VIT A1, VIT A2 etc. Instant diathermy can also be made available for
operation in positions 2 and 3.
Duallinear vitrectomy
This operating mode enables separate control of the pump by
vertical pedal movement and control of the cutting rate by
moving the pedal horizontally to the left (or vice versa). It is
programmed in ParaProg.
To exit the VIT function, you can either press a new function
button or the RESET button.
As long as the pedal is active (positions 2, 3), only the arrow
buttons and the RESET, AUX and VOICE buttons will
respond.
9 System communication
9.1 Visual displays
Light indicators serve to show selected, programmed and
current values and important information about all other unit
states on the control panel and remote controller. Warnings
and instructions are displayed in the language selected in
ParaProg. See also
Section 17.
9.2 Acoustic signals
The unit uses acoustic signals to indicate the state of the I/A
system and the output values. Different tones represent the
various states:
INFUSION OPEN
Sound of a slow drip
ASPIRATION ACTIVE
Sound of a rapid drip, whose pitch rises as the vacuum level
increases.
VACUUM LIMIT REACHED
Short beeps
REFLUX (pump reversed)
A high-pitched, rapidly-repeating signal
DIATHERMY ACTIVE
High-pitched sequence of sounds, rising with increased
output
HF CUT ACTIVE
Low-pitched sequence of tones (IDK)
Medium-pitched sequence of tones (STT)
High-pitched sequence of tones (CAPSULOTOMY)
PHACO ACTIVE 1)
Repeating combination of three beeps
Volume control
Hold down the AUX button, and select a volume level
between 0-100% with the "SOUND" arrow buttons.
NOTE: The CONTIN option can be selected in ParaProg for the acoustic
monitoring of the vacuum. The vacuum is then indicated by a wailing tone,
which rises as the vacuum value climbs to the set maximum value.
1) If specified in ParaProg
9.3 Voice confirmation
Voice confirmation will notify you about the selected function
and values as well as about warnings and instructions. You
can set up the scope of voice information for each surgeon in
ParaProg, and switch each of the following messages
individually to silent:
Warnings and instructions (VOICE MESSG)
Confirmation of selected functions (VOICE MODES)
Confirmation of set values (VOICE VALUES)
Confirmation only of changed values (CHANGE)
In addition, you can specify whether the messages should be
given out automatically (VOICE AUTOM) or only when the
VOICE button is pressed.
Volume control

29.05.09 VV016011E 18
Hold down the AUX button and adjust the volume between 0-
100% using the "VOICE" arrow buttons.
If the VOICE button is pressed while a voice message is
being given out, the transmission stops.
10 Pre-settings using ParaProg
Many important pre-settings can be made in ParaProg. It is
best to do so with the assistance of your Oertli consultant
while you are being trained in the use of the unit. However,
the parameters can also be changed at any time before or
after an operation.
ParaProg settings can be entered individually for each
surgeon.
As ParaProg variants are dependent on the software
installed, a separate ParaProg User Manual, VV016013E,
has been attached to these operating instructions.
11 Selection of setting values
Every surgeon develops his own preferred operating
technique, which also requires corresponding specific setting
values for the various stages of the operation.
The OS3 unit can optimally accommodate these individual
requirements.
The unit is supplied with the set values used during the last
trial or in the internal works test. These values are in no way
recommended or suggested values. The correct choice of
machine settings is rather the responsibility of the surgeon!
Please also note that settings from another make of operation
machine cannot necessarily be transferred to the OS3. The
type of instruments used, the irrigation and aspiration tubes
and the bottle height will also affect the functioning of the
irrigation / aspiration and vacuum modes.
As a general rule, we recommend that you start with lower
set values. Our sales consultant will be pleased to advise on
the basis of our experience during the trial and induction
period.

29.05.09 VV016011E 19
12 Cleaning and sterilisation regulations
IMPORTANT!
Make sure to adhere to guideline TN999042 (as well as to all
of the other relevant requirements that have been made
available) when preparing the instruments for re-use!
12.1 Cleaning the Control Device
The device and the control panels should be cleaned at the
end of each day of operation. Remove all BSS residue using
a soft fiber-free cloth that has been dampened with medicinal
benzene. Make sure to keep the control panels and the
device dry at all times. They are not to be spayed or rinsed.
12.2 Cleaning the Instruments
Immediately after the operation, immerse the diathermy tips,
cutting heads and handpieces in BSS or distilled water and
rinse thoroughly. The cleaning instructions supplied with the
instruments should be strictly observed!
Only use distilled or de-ionised water, neutral cleaning agents
and a soft lint-free cloth or soft sponge. Ensure that all
instruments are free from blood, tissue and impurities caused
by saline deposits or other substances. Rinse carefully and
thoroughly with distilled water, and clean carefully with
compressed air. Do not use oxygen or any other gases!
12.3 Sterilisation IMPORTANT!
Clean diathermy and capsulotomy tips immediately after
removal from the eye and keep moist with BSS or distilled
water until they can undergo final cleaning.
Steam sterilisation is the recommended method for tips,
handpieces, instruments and re-usable cassettes. ETO
sterilisation is not recommended, and gamma sterilisation is
unacceptable because of the instability of the materials.
IMPORTANT!
The user is responsible for using the correct sterilisation
method, including taking any precautions to ensure
bacteriological safety.
After cleaning (as described in Section 12.1), tips,
handpieces and instruments must be sterilised in the
autoclave with a supporting air removal device. The
recommended values are: temperature 134°C…138°C, min.
cycle time 3 minutes.
When the instruments are removed from the sterilisation
system, they must be cooled to room temperature before
commencing an operation.
The instruments should be dismantled into their individual
parts before being sterilised.
IMPORTANT!
The instruments must be sterilised before every use!
