For every use of the instrument
General
• Never operate the system unattended.
• Avoid looking directly into the light source, e.g. into the microscope objective lens or a light guide.
• When the illumination is on, the light guide must be connected at both
ends. Otherwise there is a risk of fire or burn injuries.
• Make sure that the instrument has been switched off before you
change the xenon lamp module. When switched on, the ignition system generates high voltage.
• The xenon illumination system is a high-intensity light source which if used improperly - can cause thermal injury to skin or tissue. Keep
the exposed tissue moist and provide sufficient irrigation. Carefully
monitor the effects of the illumination on the tissue, in particular in the
following cases:

Safety 21
– during prolonged procedures on skin and tissue using objective
lenses with a short focal length (short working distance),
– during procedures on tissue with a low blood supply,
– with high brightness settings of the xenon lamp.
Warning!
Due to the high luminance of the xenon lamp and its light spectrum, which
resembles that of natural daylight, its use in ophthalmic applications is
only permissible in combination with the Retrolux illumination module.
• Any kind of radiation has a detrimental effect on biological tissue.This
also applies to the light illuminating the surgical field. Please therefore
reduce the brightness and duration of illumination on the surgical field
to the absolute minimum required.
• Using the locking pedal on the base, secure the stand in position.
Make sure that the stand is stable and cannot roll away.
After every use of the instrument
• Always use the main power switch of the instrument to turn it off.
• The main power switch must always be turned off when the instrument
is not in use.
Phototoxic retinal injury in eye surgery
General
1)-5)
Several papers
surgery have been published. A comprehensive review of these publications reveals five aspects of particular concern:
– Illumination characteristics (spectral composition)
– Illumination intensity
– Angle of illumination
– Focus of the light source
dealing with the problem of phototoxicity in ophthalmic
– Exposure time to light
In the following, comments on these aspects are given and a description
of how Carl Zeiss, as a manufacturer, makes allowance for them in its
systems.
G-30-1721-en OPMI® VARIO Retrolux System Issue 1.0
Printed on 12. 03. 2008
22 Safety
Illumination characteristics (spectral composition)
Studies on the exposure of the eye to light of varying spectral composition
date back to the early 1950s. These studies suggest that the potential
hazard of phototoxic injury to the patient's retina can be reduced by
blocking out the blue and ultraviolet light below a wavelength of 475 nm.
An important point to note here, however, is that the use of filters will inevitably change the perceived color of the light. For this reason, the physician may initially have to get used to the changed appearance of the anatomical structures.
Illumination intensity
The majority of researchers suggest that the surgeon should use the
lowest light intensity required at the patient's eye to guarantee good
viewing during surgery.
Carl Zeiss has addressed this aspect by providing its systems with a device for continuously varying the brightness of the light source. This permits the surgeon to optimally adapt the light intensity at the patient's eye
to the conditions existing in each case.
Angle of illumination
1)-4)
A number of publications
suggest that the microscope should be
tilted to reduce the exposure of the macula to direct illumination.
Carl Zeiss ophthalmic surgical microscopes are therefore equipped with
the following:
– Tilting mechanism for the microscope body
Focus of the light source
Studies show that injuries are likely to occur if the filament of the light
source is imaged on the patient's retina. The peak intensity of a filament
is considerably higher than that of an even and extended light source
such as a light guide.
This is the reason why Carl Zeiss uses fiber optic illumination in its surgical microscope systems.
Exposure time to light
According to some publications, the phakic and aphakic eye should not
be exposed to the light source longer than a few minutes. In all surgical
cases, the retinal exposure time depends on the type and duration of the
procedure and possible case complications. It is therefore recommended
G-30-1721-en OPMI® VARIO Retrolux System Issue 1.0
Printed on 12. 03. 2008
Safety 23
in ophthalmic surgery to keep the light intensity as low as possible, or to
use a device which prevents the light from entering through the patient's
pupil. It is alsorecommended to make sure that the patient's eye is not additionally exposed to the light of surrounding light sources. This problem
has been solved by Carl Zeiss by the use of a retinal protection device that
can be swung into the illumination beam path of the Retrolux illumination
module.
Brightness control
The brightness control scale of our systems has a linear structure with
values ranging from 1 to 10. The stipulations of standard ISO/DDIS
15004-2:2006(E) result in maximum radiation exposure times for the different illumination configurations as specified in the table "Maximum radiation exposure times".
The microscope light source - like any bright light source - may present a
hazard to the patient's eye both in the form of immediately visible thermal
damage to the retina as well phototoxic chemical reactions which may
lead to photoretinitis. The factors which play an important role in determining the phototoxic risk are:
– Lamp brightness.
– Spectral distribution of the light (UV and blue are more dangerous
that longer wavelengths).
– Duration of direct exposure.
– Pupil size.
– Clarity of ocular media (infants and young children, for example,
may be at a higher risk).
– Phakic status of the eye (aphakic and pseudo-aphakic eyes with-
out UV and blue filtering IOLs are at a higher risk).
– Previous exposure to bright light such as retinal photography, es-
pecially within the last 24 hrs.
The following table is intended to provide the surgeon with a guideline in
determining the potential hazard. The data has been calculated for a
worst-case scenario of direct, uninterrupted exposure of an aphakic eye
with an 8 mm dilated pupil. The calculations are based on the recom-
6)
mended occupational health daily exposure limits as defined in
. A
safety factor of 10 has been used in determining these limits.
During cataract procedures, factors such as lenticular material, instruments such as the phaco handpiece, and movement of the eye provide
interruption of the exposure and would be expected to significantly
lengthen the time before photoretinits might be expected to occur.
G-30-1721-en OPMI® VARIO Retrolux System Issue 1.0
Printed on 12. 03. 2008
24 Safety
A prospective study 7) of the effects of microscope illumination during surgery did not reveal any phototoxic retinal injuries for procedure times of
up to 30 minutes if the calculated maximum recommended exposure time
was 150 seconds. However, it was also found that at the same brightness
setting, phototoxic retinal injury could be expected after approximately
100 min.
Carl Zeiss recommends the following measures in order to minimize phototoxic risk:
• Always use the lowest possible brightness setting.
• When working on the exterior eye, use the retinal protection device to
prevent light from entering the pupil, especially when the pupil is dilated.
• Turn off the microscope illumination system or cover the patient's eye
during pauses in surgery.
The following table shows the maximum radiation exposure to the xenon
illumination.
Maximum radiation exposure times
Illumination display scale Max. exposure time
2,5 3.4 minutes
5,0 1.5 minutes
7,5 1.0 minutes
10 0.8 minutes
Warning!
This exposure time must not be exceeded, as serious eye injury could
otherwise be caused by the xenon illumination.
Note:
A UV blocking filter is contained as a standard feature in the Retrolux illumination module on the microscope side.
This helps the surgeon to reduce the risk of phototoxic retinal injury in the
patient.

Widefield eyepieces with magnetic coupling
Note:
When you remove these eyepieces from the tube, please note that they
are fitted with a magnetic coupling. When mounted, the eyepieces display
a very weak magnetic field, so that the usual rules for the handling of magnets must only be observed with eyepieces which have not been mounted
on the microscope:
• Do not place the eyepieces close to instruments where there is any
risk of magnetization.
• Do not place the eyepieces on sensitive electronic units such as infusion pumps, cardiac pace-makers, measuring instruments or magnetic data carriers such as disks, audiotapes and videotapes, or credit
cards.
• Always store eyepieces not used in their original packaging.
1 Eyecup
Always adjust the eyecups in such a way that you can see the full field
of view.
– Viewing with eyeglasses: Screw in the eyecups all the way.
– Viewing without eyeglasses: Screw out the eyecups until you
see the full field of view.
2 Diopter adjustment ring
The eyepieces provide ametropia compensation between -8 D and
+5 D. Eyeglass wearers who perform surgery wearing their glasses
set the diopter adjustment ring to 0 D. Turn the ring until you have obtained the optimum setting. An integrated brake holds the ring in the
position set.

Description of the modules
The floor stand comprises an articulated arm, a stand column and a stand
base. The articulated arm comprises a carrier arm and a suspension arm.
The carrier arm contains the control unit with all electrical supply systems
required for the control of a motorized surgical microscope. These motorized functions can be activated using a foot control panel.
The suspension arm permits almost effortless positioning of the surgical
microscope. The spring force of the suspension arm can be varied in a
range from 8 to 20 kg, permitting reliable balancing of the microscope
even with heavy accessory equipment. The downward movement of the
suspension arm can be limited as required.
A maneuvering handle attached to the stand column is used to move the
stand and to attach the foot control panel. The stand column is provided
on its left and right with cable supports for winding up cables before the
unit is relocated. Four steerable casters on the stand base permit easy
positioning near the operating table. The stand base has been designed
in such a way that high stability is ensured even with unfavorable loading
of the stand. A locking pedal is provided to lock the floor stand quickly and
reliably into position.

Lamp housing with xenon light source
Warning!
The use of OPMI Vario for ophthalmic procedures is only permissible in
combination with the Retrolux illumination module.
The suspension system is equipped with a xenon illumination system for
fiber illumination. The xenon lamp generates light whose spectrum resembles that of natural daylight. Regardless of the brightness setting, the
color temperature of the light always remains the same. Normal daylight
film without any additional conversion filters can therefore be used for
photographic documentation. The lamp housing contains two xenon
lamps. The second lamp is used as a backup lamp which must be swung
into the illumination beam path should the first lamp fail.
Ventilation grid
Do not cover the ventilation grid! For example, drapes could be covering
the grid. This can cause the lamp modules to overheat and lead to lamp
failure.

Video monitor (option)
The S88 floor stand can be equipped or retrofitted with a TFT monitor (1).
In the case of retrofitting, our service staff or an authorized person will install the TFT monitor on your suspension system.
The TFT monitor (1) features a 15" screen and permits the scrub nurse
and other OR staff to follow the surgical procedure. For optimum viewing,
the TFT monitor can be precisely positioned using flexible arm (2).
Warning!
Risk of injury due to lowering of the TFT monitor!
• Ageing processes may lead to the loss of gas in the gas pressure
spring of the monitor's suspension arm, causing the TFT monitor to
move downward of its own accord.
• Compensate for the loss of gas by readjusting the gas pressure spring
as described on page 180.
If the TFT monitor continues to move downward, the gas pressure spring
is defective.
• Notify our service representative.
Warning!
Do not use the stored video sequences, video clips (cut sequences) and
single images for diagnostic purposes, as the video cameras and the
monitor have not been calibrated. The visualized images may therefore
include deviations in scale, color and shape.
This applies in particular if the sequences, clips or images are viewed on
a monitor outside the OR, as the transmission to a different monitor may
lead to changes in the display.
Note:
The background illumination of the LCD display has a limited service life.
If you notice that the display is getting darker or starts to flicker, contact
your Zeiss dealer.

Design
The 8-function and 14-function foot control panels feature two rocker
switches (1) which are used to control the ”Zoom” and ”Focus” functions.
The switches for these functions are located on one side, allowing you to
control both directions of a function using toe/heel movement without
having to shift your foot. Bridge (3) between two rocker switches (1)
serves as a support to rest your foot on.
Connector (2) is used to connect the foot control panel to the appropriate
connector on a suspension system or a wall-mounted control panel.
The foot control panel is provided with a waterproof rubber cover.
The illustration shows the 14-function foot control panel. Depending on
the configuration involved, an 8-function foot control panel can also be
connected.
