1 Application and description
The OS3 Vitrex operating unit is used for surgical
procedures in the posterior segment of the eye. It can be
used as a stand-alone unit or, preferably, in conjunction
with the OS3 VC830100 base unit.
The functional features offered by the instrument include
inter-ocular lighting, an air pump to maintain inner eye
pressure and a pump for the injection and extraction of
visco-elastic substances.
IMPORTANT!
Alterations and repairs may only be undertaken by persons
authorised by the manufacturer, otherwise the proper
functioning of the unit may be impaired.
CAUTION!
The unit must never be used in areas containing
inflammable anaesthetics!
The unit actuates and controls the accompanying
instrumentation and consumable materials within the
performance limit values selected by the operator in each
case, and as set on the control panel. A foot pedal is used
for the fine adjustment of these values within the specified
range. The unit is extremely easy to operate. Frequently
used settings can be stored and recalled.
The unit may only be used with the Oertli instruments and
consumable materials recommended and supplied by the
manufacturer (see Section 11).
The unit may only be operated by trained personnel. The
surgeon is responsible for defining the correct settings.
The unit is not suitable for surgical interventions outside the
eye. If in doubt, please contact the manufacturer.
2 Important points and hazards
IMPORTANT!
Please read these instructions very carefully before using
the apparatus for the first time!
IMPORTANT!
When setting up the unit, ensure that neither the rear
ventilation holes nor the top of the unit are covered.
CAUTION!
Never look directly into the lamps when they are lit!
IMPORTANT!
Mobile telephones and other appliances that use radio
frequencies may cause unexpected or undesirable
behaviour of the unit or system!
IMPORTANT!
Never place the unit or system next to or on top of other
appliances when operating it. If it is necessary to arrange
the appliances in this way, it must be checked in each case
that the unit or system is working correctly.
NOTE!
In order to avoid the risk of electric shock, this unit may
only be connected to mains supplies with a protective earth
connection.
IMPORTANT!
The user is responsible for ensuring compliance with and
fulfilment of IEC 60601-1
IMPORTANT!
Before connecting the unit, check that the voltage shown
on the rating plate is the same as that of the operating
room!
CAUTION!
The Visco instrument connections (INJCT and EXTR) must
never come into direct contact with the eye! If a syringe is
to be used as a silicone container, care must be taken to
ensure that there is no air in the syringe reservoir!
IMPORTANT!
While in the EXTR mode, ensure that liquid is never sucked
into the unit at the Visco instrument connection, especially
during the application of substances with a lower viscosity.
IMPORTANT!
The correct choice of equipment settings is the
responsibility of the surgeon!
Settings given in this instruction manual are suggestions
only.
IMPORTANT!
Only those instruments and accessories supplied by the
manufacturer and listed in Section 11 may be used!

The control panel
40 mmHg
0.50 bar
0.10 bar
All settings for operating the OS3 Vitrex unit can be entered
on the control panel (pre-settings are entered in ParaProg,
see Section 7). A visual display shows at a glance the
operating state of the system and the current values.
The buttons respond to gentle pressure which can also be
applied either with a sterile swab or the sterile operating
pen (VE850003) available from the manufacturer.
Depending on the stage of the operation or the position of
the control pedal, certain buttons will be disabled. This
feature offers increased protection against improper use.
The execution of a command is accompanied by
corresponding changes in the display field. If a disabled
button is pressed, no change is shown on the display.
The control panel cannot be separated from the unit. If you
are using it in combination with the OS3 VC830100 base
unit, a VE830020 remote controller can be attached.
2.1 Arrangement of control and indicator elements
Diplay and
setting area
Function
selection area
Injection pressure indicator
Displays the selected limit value (current value flashes
when active) of the injection pressure at the VISCO (B)
outlet. The unit of measurement can be set using ParaProg
(mmHg, PSI, kPa).
Extraction vacuum indicator
Displays the selected limit value (current value flashes
when active) of the extraction vacuum at the VISCO (B)
outlet. The unit of measurement can be set using ParaProg
(mmHg, PSI, kPa).
Arrow buttons
The arrow buttons can be used to reduce (down arrow) or
increase (up arrow) the value shown in the display field
immediately above. Exert normal pressure to change the
value slowly or in individual increments, or fully depress for
rapid value setting.
The function selection area
AIR1 button and indicator light
Activates the AIR function with the pressure value stored in
memory 1. The indicator lamp lights up.
Press again to activate the pump and reduce pressure.
Pressing once more will deactivate the pump and the
function and switch off the indicator lamp.
The control and indicator elements are grouped in such a
way that they can be operated after only a short period of
familiarisation, even in semi-darkness. The top half of the
control panel is the indicator and setting area. It is designed
to show at a glance the operating state of the unit and the
current values. The values displayed can be increased or
reduced using the dark green arrow buttons directly below
the value displays.
The lower half of the control panel houses the function
selection buttons.
Please familiarise yourself thoroughly with this ergonomic
arrangement of the control elements; it will enable you to
operate the equipment quickly almost "blind"!
