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.

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.
•
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 23.
S7 floor stand • Using the brake tabs on the base, secure the stand in position. Make sure that the stand is stable and cannot roll away. S7 ceiling mount with lifting column • The lifting column is used to move the microscope into position for surgery prior to the surgical procedure. Do not constantly move the lifting column up and down, since a thermal cut-out will then automatically switch off the drive motor. If this occurs, the lifting column cannot be moved again until the motor has cooled down. After every use of the system

•
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.

Safety
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! Risk of collision!

•
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 locking lever 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 Several papers1)-5) dealing with the problem of phototoxicity in ophthalmic 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 – Exposure time to light
G-30-1681-en
OPMI® Lumera®
Issue 2.2 Printed on 12. 12. 2011

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 (coaxial illumination)
