Field of use Intended use OPMI LUMERA 700 is a surgical microscope intended for the illumination and magnification of the surgical area and for the support of visualization in surgical procedures in the field of ophthalmology.
Normal use In line with the intended use of the system, you can use it for surgical procedures on both the anterior segment of the eye (e.g. cataract, cornea, glaucoma) and the posterior segment of the eye (retina, vitreous). The system-integrated SCI illumination provides an optimum red reflex and delivers a sharply defined, high-contrast image of the patient's eye. The freely programmable foot control panel or, alternatively, the handgrips ensure maximum operating comfort for the surgeon who can configure all settings required to meet his/her specific needs. In addition, the OR staff can change the configuration of the microscope and of the integrated camera or USB video recording functions via the adjustable 5.7" control panel. The fast focus allows rapid movement over a defined travel range and enables the surgeon to move the focus very easily over long distances (e.g. for folding lenses) and back to its initial position. Assistant functions such as the keratoscope or the integrated slit illuminator expand the surgeon's scope of work. After completion of the surgical procedure, the system can be reset to the selected, freely programmable starting values via the standby position or reset function to ensure an optimum starting position for the next surgery. The system can be supplemented by various accessories and can be prepared for sterile use by attaching resterilizable caps, handgrips and drapes. The system is intended for use in offices, hospitals or other human medicine institutions. For disposal, please observe the instructions in this manual as well as the applicable legal regulations in your country.

•
In order to prevent phototoxic damages to the patient's eye, reduce the brightness and the light exposure of the surgical area to an amount that is absolutely necessary for the surgery.
•
In order to prevent phototoxic damages to the patient's eye during surgery, use a retina protection filter (blue barrier filter) and/or a retina protection device that are integrated into the light source.
•
In order to prevent phototoxic damages to the patient's eye, adjust the irradiation intensity and the associated irradiation time by selecting the appropriate illumination setting. The values recommended by Carl Zeiss can be found in table "Maximum radiation exposure times" on page 22. Any deviation from these values is only permissible when medically justified.
•
In order to prevent phototoxic damages, never look directly into the light source, e.g. on the microscope or the light guide.
•
Never leave a device unattended with the light source still switched on, as excessive radiation exposure times may lead to retinal injury in the patient's eye.
•
When operating the handgrips or the zoom knob on the assistant's microscope, do not touch the non-sterile connecting cable to avoid infecting the patient.
•
If you have mounted the RESIGHT fundus viewing system on the underside of the microscope and steeply tilt the microscope, the RESIGHT fundus viewing system may unintentionally move in and injure the patient. Remove the RESIGHT fundus viewing system before steeply tilting the microscope.

Measures to prevent phototoxic injury 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
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. Integrated protection filters
For protection of the retina, Carl Zeiss offers the swing-in retina protection filter (blue barrier filter) and the stationary UV blocking filter as standard features of the surgical microscope. 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 orange color of the retina protection filter will inevitably change the perceived color of the light. For this reason, the surgeon 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
Page 18

OPMI LUMERA® 700
Safety measures
surgery. Brightness control
For this reason, the brightness of the light source in Carl Zeiss systems is continuously variable. 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 A number of publications1)-4) suggest that the microscope should be tilted to reduce the exposure of the macula to direct illumination. Tilting mechanism
The surgical microscope features a tilting mechanism for the main microscope to enable indirect illumination.
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. Fiber optic illumination
Version 3.0 G-30-1673-en
This is the reason why Carl Zeiss uses fiber optic illumination in its surgical microscope systems.
Page 19
Safety measures
OPMI LUMERA® 700
Exposure time to light According to some publications, the eye should not be exposed to the light source longer than a few minutes. In all surgical cases, the retinal exposure time to light 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 retina protection device that can be swung into the microscope's illumination beam path and a swing-in retina protection filter (blue barrier filter). Brightness adjustment
The brightness of this device can be adjusted on a scale from 5% to 100%. Based on standard DIN EN ISO 15004-2:2007 there are maximum illumination times for various illumination configurations. These values can be found on table "Maximum radiation exposure time" (see page 22). With increasing age of the light source, the actual illumination intensity delivered at the respective setting decreases (this is a normal property of the system).
Phototoxic risk factors
The microscope light source - like any bright light source - may present a potential 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 light is 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)
–
Condition of the eye: aphakic and pseudo-aphakic eyes with IOLs are at a higher risk.
–
Previous exposure to bright light such as retinal photography, especially within the last 24 hours
During cataract procedures, factors such as lenticular material, instruments
