1 INTRODUCTION 1

The LABOMED Prima OPH is an Ophthalmic microscope, which is adaptable for different surgical needs without
compromise to performance.
The microscope provides extremely high optical image quality, good depth of focus and wide field of view for
precise surgery. Illumination control, inbuilt tilt, adjustment of the observation head help to reduce the
surgeon’s work fatigue and allow comfortable use over long period.
1. The observation head can easily be positioned with the help of suspension arm .
2. An advanced 5-step magnification changer allows an optimal magnification for a particular surgery from
five different magnifications.
3. Auto home position for X-Y movement can be done by touch of a button.
4. Cold light illumination with a high intensity 150W Halogen lamp is provided using a fiber optic guide for
proper illumination. The illumination is further adjustable up to its most suitable brightness using
intensity control knob suitably located at the suspension arm, and is easily approachable to the surgeon.
5. The simple lamp changing mechanism allows to change lamp quickly when the lamp in use blows
during operation.
6. The power supply to the lamp automatically goes OFF when the suspension arm is raised to its top
most position.
7. When the microscope is not in use, the suspension arm can be folded over the main body to store it
compactly.
8. Rigid H-form base with castor wheels provides greater stability as well as mobility to the instrument.

SAFETY INSTRUCTIONS
2Prima OPH
Very important : For identification, service people must know the serial number of the
microscope.
Intended Use:
1. This microscope is manufactured according to the safety norms as per CE regulation and FDA.
2. This microscope is intended for use only as prescribed in this manual.
3. Servicing and repairs are allowed through authorized persons only.
4. Replace burnt out fuses by live fuses of the same type only (rated voltage, rated current, switch
– off characteristics.)
5. Use mains plug and mains socket both with protective earth conductors only.
6. Do not use force while fixing cable connections. If the male and female parts do not readily
connect, make sure that they are appropriate for one another. If any of the connectors are
damaged. Please contact the representative.
7. Make sure that inlets and outlets of ventilation system for cooling the housing are open (not
covered).
8. The microscope is built for use in dry rooms only. Take care that no fluids enter the microscope

9. Microscope is protected against overheating through a thermal cut-off.
10. The manufacturer will not accept any liability for damage caused by unauthorized persons
tampering with the instrument; this will also forfeit any rights to claim warranty.
11. It is recommended to use the instrument only with the accessories supplied. In case you wish to
use other accessory, make sure that LABOMED has certified that its use will not impair the
safety of instrument.
The Prima OPH is a universal instrument for operative and diagnostic medical use. It is useful for
optimal illumination and magnification of the attendance area with the possibility of:
1. Manual variations of magnification
2. Motorized focusing (Z-axis) through foot control
3. Motorized centering of attendance area in XY directions through a Joystick provided on the foot
control (applicable to the suitable model)

SPECIAL INSTRUCTIONS
3
3.1
1. Check all Electrical connections.
2. Attach sterilized covers, panels or caps which have been re-moved or opened.
3. Pay special attention to labels on the instrument, such as caution label, warning triangles
with exclamation marks or notes.
4. Do not cover nay ventilation openings.
3.2
1. Avoid looking directly into the light source, microscope objectives lens or light guide.
2. When the illumination is on, the light guide must be connected at both ends. Otherwise there
is a risk of fire or burn injuries.
3. Any kind of radiations has a detrimental effect on biological tissue. This also applies to
illuminating the surgical field, therefore adjust the brightness and duration of illumination on
the surgical field to the absolute minimum required.
4. Adjust tension of suspension arm as per convenience.
3.3
1. Switch off the Mains sullpy to the instrument.
2. When the microscope is not in use, the suspension arm can be folded over the main body for
compact storage.

8Electrical Connections
8.1 Adjusting mains Voltage:
Connect the power cable to the AC inlet socket provided on
the illumination box and check the voltage settings at the
voltage selector switch. The line voltage of the electrical
system is set in the factory the rated line voltage of the
country of destination which must be either 110V or 220V
AC. The line voltage available at the site of installation must
lie within the admissible voltage range. If this is not the case
you must not operate the system.
8.2 Connections of Various Controls:
8.2.1 Connect 7 pin connector from X-Y coupling assembly to
terminal of electrical box.
8.2.2 Connect 4 pin connector from Z-axis motorized control
assembly to terminal of electrical box.
8.2.3 Connect 12-pin connector from foot control to terminal of
electrical box.
This completes your electrical connections.

After Supplementary accessories are mounted, the
additional load of suspension arm must be compensated by
adjusting tension on tension control screw provided on
suspension arm by moving it clock wise or anticlockwise.
For Diagnosis:
