3 Safety notes
The PROVEO 8 surgical microscope is state-of-the-art technology.
Nevertheless, hazards can arise during operation.
X Always follow the instructions in this user manual, and in
particular the safety notes.
3.1 Intended use
• The PROVEO 8 surgical microscope is an optical instrument for
improving the visibility of objects through magnification and
illumination. It can be applied for observation and
documentation and for human and veterinary medical
treatment.
• The major field of use is Ophtalmology.
• The microscope device is not for use in microsurgery (Neuro,
Plastic/Reconstructive, Ear, Nose and Throat surgeries).
• The PROVEO 8 surgical microscope may be used only in closed
rooms and must be placed on a solid floor or mounted to the

3.3 Directions for the operator of the
instrument
X Follow the instructions described here.
X Follow the instructions given by your employer regarding the
organization of work and safety at work.
Phototoxic damage to the retina during eye surgery
WARNING
Damage to the retina due to prolonged exposure!
The light of the instrument may be harmful. Risk of retina
damage increases with the duration of exposure.
X During exposure to the light from this instrument, do
not exceed the hazard reference values.
If the exposure time exceeds the value in the table on
page 4with this instrument at maximum output
power, the hazard reference value will be exceeded.
The following table is intended to serve as a guideline and make
the surgeon aware of the potential hazard. The data have been
calculated for the worst-case scenario:
• Eye with aphakia
• Completely unmoving eye (continuous irradiation of the same
region)
• Uninterrupted light exposure, e.g. no surgical instruments in
the eye
• Pupils dilated to 7 mm
The calculations are based on the corresponding ISO standard1) and
the exposure limit values recommended in that standard. .
Main light
Light setting Recommended maximum exposure time according to 1) [min.]
25% 6.5
50 % 2.5
75% 1.5
100 % 1
Retina Protection
Function Activated 16.5
Coaxial Red Reflex illumination
Light setting Recommended maximum exposure time according to 1) [min.]
25% 10
50 % 4.5
75% 3
100 % 2
Retina Protection
Function Activated 14
Sources:
1) DIN EN ISO 15004-2; Ophthalmic instruments - Fundamental
requirements and test methods - Part 2: Light hazard
protection.
If both illuminations are used, the lower of the two values
for the permitted exposure time must be used according to
the configured light output. The two hazards do not have to
be set off against each other, as their reflections on the
retina are not superimposed. This also applies to the use of
the Slit Illumination "Phototoxic damage to the retina
during eye surgery" on page 4.
Slit illumination
The following table shows the allowed surgery durations and their
possible extension when reducing the slit width:
Slit width [mm] Time [min.]
>6 1
5 1.2
4 1.5
3 2
2 3
Protect the patient with the following safeguards:
• Short exposure times
• Low brightness settings
• Switching off the illumination during breaks in the operation
It is recommended to adjust the brightness to the minimum
necessary for the surgery. Infants, patients with aphakia (whose
eye lens has not been replaced by an artificial lens with a UV
protection screen), small children and persons with diseases of the
eye are at greater risk. The risk is also increased if the person being
treated or operated on has, within the last 24 hours, already been
exposed to illumination from the same or any other
ophthalmological instrument that uses a bright visible light source.
This applies especially to patients that have been examined via
retinal photography.
Decisions about brightness must be made case by case. In any
event, the surgeon must evaluate the risks and benefits of the used
light intensity. Despite all efforts to minimize the risk of retinal
injury by surgical microscopes, damage may still occur.
Photochemical retinal damage is a possible complication of the
necessity to use bright light to make eye structures visible during
difficult ophthalmological processes.
In addition, the Retina Protection function can be activated during
the surgery to reduce the main light intensity below 10% and
RedReflex below 20%.

Functions
5 Functions
5.1 Balancing system
With a balanced surgical microscope PROVEO 8 you can move the
optics carrier to any position without tilting or moving down.
After balancing all movements during operation only need a minor
force.
The parallelogramm balances the up/down movement.
Balancing the parallelogram see chapter 7.7.1.
Balancing the optics carrier at the F42 floor stand
Balancing the optics carrier at the CT42 telescope mount
5.2 Brakes
The PROVEO 8 surgical microscope has 4 electromagnetic brakes
which stop the movements of the stand, the ceiling mount and the
surgical microscope:
The electromagnetic brakes can be released via handle or nurse
switch.

Functions
5.3 Illumination
The illumination of the surgical microscope PROVEO 8 consists of
two LED modules and are located in the optics carrier.
There are two lamps, main lamp and Red Reflex lamp.
5.4 Fusion Optics
This feature provides an augmentation in resolution and depth of
field for an ideal 3-D optical image.
Fusion Optics operates with two separate beam paths with
different information: the left beam path is optimized for high
resolution, the right beam path for optimum depth of field.
The human brain merges these two very different images to a
single, optimal spatial image.
