For every use of the instrument
General
• Never operate the system unattended.
• Excessive radiation exposure times may lead to retinal injury in the patient's eye. Never leave a system unattended when the light source
has been activated.

Printed on 02. 02. 2009
24 Safety
• 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.
Xenon lamps feature high luminance and a spectrum resembling that of
natural daylight. Therefore, only special xenon lamps approved by Carl
Zeiss must be used in ophthalmology.
• 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.
• Phototoxic effect of light beams. When operating on the eye, always
use the yellow protection filter to ensure that the patient's eye is not
exposed to unnecessary (blue) radiation (risk of retinal injury).
• Adjust the illumination intensity as required for the type of illumination
used and the radiation exposure time. You will find the values recommended by Carl Zeiss in the table "Maximum radiation exposure
times" on page 29.
S88 floor stand
• Using the locking pedal on the base, secure the stand in position.
Make sure that the stand is stable and cannot roll away.

Risk of collision!
When using a wide-angle observation system (e.g. BIOM 3)
When using a wide-angle observation system (e.g. BIOM 3 from Oculus)
which is usually installed between the surgical microscope and the patient, make sure that the patient is neither put at risk nor injured by the motorized focusing system or the movement of the suspension system arm.
Only use accessories expressly certified by the manufacturer for combination with the surgical microscopes described in this manual.
Warning!
• With the wide-angle observation system swung out of position, always
position the microscope body in such a way that index dot (1) of the
microscope's focus is in the middle of triangle (2) of the marking.
• Select a medium magnification (e.g. 1.0).
• Lower the surgical microscope toward the surgical field until you see
the patient's cornea sharply defined.
• Turn the setting screw for limiting the downward movement clockwise
as far as it will go and check without the patient that the suspension
arm cannot be lowered any further.
It is vital that you read the user manual for the wide-angle observation
system used (e.g. BIOM 3 from Oculus).
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
dealing with the problem of phototoxicity in ophthalmic
G-30-1682-en OPMI® Lumera® T Issue 4.0
– Angle of illumination
– Focus of the light source
– Exposure time to light
Printed on 02. 02. 2009
26 Safety
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.
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.
For protection of the retina, Carl Zeiss offers the blue barrier filter (retina
protection filter) as a standard feature of the OPMI Lumera surgical microscopes. This reduces not only the exposure of the patient's eye to light,
but also that of the surgeon's.
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
– Surrounding field illumination with brightness control
– Red reflex illumination (stereo coaxial illumination)
G-30-1682-en OPMI® Lumera® T Issue 4.0
Printed on 02. 02. 2009
Safety 27
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
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 also recommended 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 microscope's illumination beam path
and a blue barrier filter (retina protection filter).
Brightness control
The brightness control scale of our systems has a linear structure with
values ranging from 0.5 to 10. The stipulations of standard ISO/FDIS
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 as 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
than longer wavelengths).
– Duration of direct exposure.
– Pupil size.
– Clarity of ocular media (infants and young children, for example,
may be at a higher risk).

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

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 photoretinitis might be expected to occur.
A prospective study
gery 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

The red reflex illumination (stereo coaxial illumination) of OPMI Lumera
has been designed to provide a bright red reflex using only very small
quantities of light at the center of the light spot. The peripheral field illumination causes higher exposure of the retina, but usually not directly of the
macula, depending on the position of the eye. For cataract procedures,
we recommend adjusting the surrounding field illumination to be somewhat darker than the central red reflex spot. Not only does this setting
minimize phototoxic risk, but it also reduces glare from the patient's
sclera.
Other recommendations for minimizing phototoxic risk are:
• Always use the lowest possible brightness setting.
• Use the blue barrier filter (retina protection filter) to block the blue
spectrum of light. The blue barrier filter will increase the recommended
exposure times by factor three.
• 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.

Lumera T surgical microscope
Intended use
The Lumera T surgical microscope has been designed for the magnified
visualization of the field of view during surgical procedures in ophthalmology. The illumination system of the surgical microscope features red
reflex illumination and surrounding field illumination, providing very effective illumination of the field of view and optimum visualization of the red
reflex.
Note:
The illumination system of the Lumera T surgical microscope contains a
UV blocking filter as a standard feature. This helps the surgeon to reduce
the risk of phototoxic retinal injury in the patient.
Description of components
The Lumera T surgical microscope comprises the following components:
1 X-Y coupling
The X-Y coupling allows motorized fine positioning of the surgical microscope in a horizontal plane. The range of travel is 40 mm x 40 mm.
The speed of travel can be set on the control panel of the suspension
system.
The X-Y coupling is provided with a recentering mechanism. When
you press reset button (2) or an appropriately programmed button of
the foot control panel (4),
– the X-Y coupling adopts its center position,
– the focusing system of the surgical microscope is reset to its initial
position (3).

2 Support arm for the surgical microscope
The support arm incorporates a tilt device (3). This allows the viewing
direction of the surgical microscope to be adapted to the requirements
of the surgical field. Using the knob for fine tilt, you can position the
surgical microscope in a range from +90° to -90° (+ in the direction of
the surgeon and - in the opposite direction). The +90° setting is ideal
for surgery on patients in a seated position or lying on their side.
Caution:
Do not tilt the microscope beyond + / -90°, as this could damage the
microscope cable or the light guide.
3 Knob for tilt device
4 Surgical microscope
The apochromatic optics of the surgical microscope provide superb
optical quality. The microscope image displays optimum contrast and
excellent detail recognition along with a large depth of field. The bright
microscope image is a particular benefit in vitreoretinal surgery. A 1:6
ratio zoom system allows the magnification of the overall system to be
set as required by the surgical procedure. Two apochromatic objective
lenses with focal lengths of 175 mm and 200 mm are available for different working distances.
5 Invertertube for the main surgeon
6 Invertertube for the assistant
Tubes (5) and (6) offer an inverter function for ophthalmic applications.
The inverter is used to bring an inverted image created by a wideangle observation system into the correct position.
With the inverter deactivated, tubes (5) and (6) have the same optical
function as normal tiltable tubes.
7 180° tiltable binocular tube (option)
Due to its large tilt range, the tiltable binocular tube allows optimum
adaptation to extreme surgical conditions.
8 45° inclined binocular tube (option)
This tube is used as a viewing device for the surgeon. The viewing
angle of 45° allows work with minimum fatigue.
The standard equipment includes eyepieces with a magnification factor of
10x (option: 12.5x ).

9 Integrated assistant's microscope
The integrated assistant's microscope in its standard version comes
as an integral part of OPMI Lumera T. The assistant sees the same
image as the main surgeon in the same image quality.
The assistant's microscope has two working positions. They are located on the right and left of the main surgeon at an angle of 90° to the
main surgeon's viewing direction. No locking mechanism has been
provided, allowing the assistant to move the assistant's microscope by
a certain amount out of the 90° position, if necessary.
Warning!
To prevent the assistant's microscope from moving downward of its
own accord when the main microscope is being tilted, the assistant's
microscope must be adjusted and locked in position using screw (9)
before surgery.
The assistant's microscope is equipped with a focusing system and a
5-step magnification changer. This enables the assistant to adjust his/
her microscope image independently of the main surgeon.
The binocular tube can be turned by ± 12° about the optical axis of the
assistant's microscope. In addition, the assistant's microscope can be
tilted by 15°. If the assistant finds the viewing angle too steep, an optical wedge (option) can be installed between the microscope body
and the binocular tube to permit horizontal viewing.
The standard equipment includes eyepieces with a magnification
factor of 10x, providing a low initial magnification. This offers the benefit of a wide field of view and an improved overview of the surgical
field. The assistant sees the red reflex in both eyepieces.
10 Locking screw for the integrated assistant's microscope
After adjusting the assistant's microscope as required, secure it in position using this screw.
Caution:
Please note the explanations given in the section "Adjusting the tilt motion" on page 174.

Illumination system
With red reflex illumination (stereo coaxial illumination) and surrounding
field illumination, the illumination system of the surgical microscope has
been specially tailored to the requirements of ophthalmic applications.
The illumination options provide very effective illumination of the field of
view and optimum visualization of the red reflex.
To protect the patient's eye, the illumination system is equipped with a
retina protection device and a blue barrier filter (retina protection filter.
The retinal protection device covers the patient's pupil and prevents light
from entering the patient's eye. It is integrated in the surgical microscope
and can be swung into the beam path when the red reflex is not needed.
The blue barrier filter (retina protection filter) reduces the retinal exposure
of the patient's and surgeon's eyes and permits the radiation exposure
time to be increased by factor 3. It can be swung into the beam path of the
light source in the suspension system.
The light is supplied by a light guide which directs the light from the light
source in the suspension system to the surgical microscope. To switch
the light source and the illumination systems on and off and to control their
brightness, you can use both the foot control panel and the control panel
of the suspension system.
Surrounding field illumination
The surrounding field illumination is integrated in the surgical microscope
and provides an optimally illuminated field of view with superb detail recognition. The brightness is controlled via the foot control panel or the suspension system. In addition, the intensity of the surrounding field illumination can be separately reduced or completely deactivated using knob (1)
on the surgical microscope.
Red reflex illumination
The red reflex illumination (stereo coaxial illumination) is integrated in the
surgical microscope and provides an optimally visible red reflex. For information on how to ensure optimum red reflex visualization, please see
page 172.

Illumination settings
The type of illumination required can be selected using knob (1) on the
surgical microscope.
Type of illumination
Red reflex illumination
This is the best setting to generate an optimum red reflex.
Glare from the sclera is effectively reduced as only the central field of view is illuminated.
Red reflex with surrounding field illumination
This setting permits clear visualization of the red reflex combined with illumination of the surrounding field of view.
Surrounding field illumination
This setting is used for illuminating the field of view if no red
reflex is required.
Surrounding field illumination with retina protection device
In this setting, a retina protection device is swung into the
surrounding field illumination beam path. It prevents light
from entering into the pupil and provides additional protection for the patient's eye against phototoxic injury.
Warning!
– Avoid looking directly into the light source, e.g. into the microscope ob-
jective lens or light guide!
– Adjust the illumination of patient's eye through the surgical micro-
scope to a level which ensures that the fundus is exposed to as little
light as possible.
– If no red reflex is required, swing the retinal protection device into the
beam path.
– When operating on the eye, use the blue barrier filter (retina protection
filter). It protects the patient's retina against unnecessary (blue) radiation and permits the radiation exposure time to be increased by
factor 3.

14 DeepView button (depth of field (DoF) management system)
Allows you to optimize the light transmission or depth of field, depending on the application involved. When this function is deactivated
(LED not lit), the microscope is optimized for light transmission. When
this function is activated (green LED is lit), the microscope is automatically set to optimized depth of field in accordance with the selected
magnification. This mode is primarily recommended for procedures on
the anterior segment where high depth of field is required.
The next time the system is switched on, the mode last selected will
be activated.
15 Manual adjustment of the zoom system in the emergency mode
16 Selection knob for different types of illumination
Red reflex illumination
This is the best setting to generate an optimum red reflex. Glare
from the sclera is effectively reduced as only the central field of
view is illuminated.
Red reflex with surrounding field illumination
This setting permits clear visualization of the red reflex combined with illumination of the surrounding field of view.
Surrounding field illumination
This setting is used for illuminating the field of view if no red reflex is required.
Surrounding field illumination with retina protection device
In this setting, a retina protection device is swung into the surrounding field illumination beam path. It prevents light from entering into the pupil and provides additional protection for the
patient's eye against phototoxic injury.

Caution:
Take care not to damage the light guide connector and light guide!
• Always insert the correct end of the light guide into the light guide con-
nector. For correct mounting, please see the label provided under the

Invertertube™
The tiltable tube has an inverter function and has been designed for ophthalmic use. Many wide-angle observation systems for the posterior segment of the eye provide an inverted intermediate image which is viewed
through the surgical microscope. The inverter is used to erect an inverted
image.
When activating the wide-angle observation system, you must also activate the inverter of the tiltable tube. When swinging out the wide-angle observation system, you must also deactivate the inverter of the tiltable tube
again.
With the inverter deactivated, the tiltable tube has the same optical function as a normal tiltable tube.
To ensure sterility, the controls can be equipped with sterilizable caps.

Widefield eyepieces with magnetic coupling
Note:
When the eyepiece has been removed from the tube, please remember
that it is equipped with a magnetic coupling. Attached eyepieces produce
a very minor magnetic field, i.e. the usual regulations for the handling of
magnets must only be observed with non-attached eyepieces.
• Do not place the eyepiece near instruments which may be magnetiz-
able.
• Do not place the eyepiece on sensitive electronic instruments such as
infusion pumps, heart pacemakers, measuring instruments or magnetic data carriers such as disks, audio/video tapes or credit cards.
• Always store the eyepiece in its original packaging, when not using it.
1 Eyecup
Always adjust the eyecups in such a way that the entire field of view
can be seen.
– Viewing with eyeglass-
Screw in the eyecups all the way.
es:
– Viewing without eye-
glasses:
Adapt the eyecups to the viewer's field
of view by screwing them outward.
2 Diopter setting ring
The eyepieces enable you to set your prescription between -8 D and
+5 D. Eyeglass wearers using their glasses during work should set the
diopter setting ring to 0. Turn the ring until the optimum setting has
been achieved. An integrated brake holds the setting ring in the position set.

Light sources
The suspension system is equipped either with a halogen light source, a
Superlux Eye light source or with a Superlux Eye light source with an additional, integrated halogen light source (option).
1 Superlux Eye light source
This illumination system comprises a xenon lamp featuring 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. For changing the light spectrum, two Superlux Eye light sources with two xenon lamps and different swing-in
filters are available. The second lamp is used as a backup lamp which
must be manually swung into the illumination beam path when the first
lamp fails. You have to pull out the lamp module all the way before
being able to swing in the backup lamp.
Warning!
When using the Superlux Eye light source, only operate the system with
special xenon lamps approved by Carl Zeiss for ophthalmic surgery. If any
other than Carl Zeiss-approved xenon lamps are used, there is the risk of
severe injury to the patient's eye.
2 Halogen light source (option)
This illumination system comprises a light source featuring fiber illumination. The lamp housing contains a backup lamp which is automatically swung into the illumination beam path when the first lamp fails.
If required, the light source can be equipped with a second lamp
housing so that two separate light sources are available for fiber illumination. The second light source can be used, for example, for a fiber
slit lamp.
3 Superlux Eye illumination system with additional integrated halogen il-
lumination (option)
The additional, integrated halogen illumination is a second illumination
system suitable e.g. for the use of a fiber slit lamp.
