Avoid looking directly into the light source, e. 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. When operating on the eye, always use a GG protection filter to ensure that the patient's retina is not exposed to unnecessary blue radiation retinal injury.

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. 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:. 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 exposure of the eye to light of varying spectral composition date back to the early s.
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 nm. Carl Zeiss provides a GG retina protection filter for surgical microscopes recommended for use in ophthalmic surgery.
This reduces not only the light exposure of the patient's eye, but also that of the surgeon's. It should be noted in this context that the use of filters inevitably leads to a change in the color of the light. The surgeon may therefore have to get used to the changed appearance of 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 A number of publications1 -4 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:. 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 or aphakic eye should not be exposed to the light source longer than a few minutes. In every operation the exposure of the retina to light is dependent on the type and duration of surgery and on any complications which occur.
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. Also, the surrounding light sources should not cause additional strain to the patient's eye. Carl Zeiss has provided an answer to this problem in the form of a swingin retinal protection device for insertion into the beam path of the surgical microscope.
This device ensures total eclipsing of the pupil, preventing light from entering into the patient's eye. It can be swung out when a red reflex is required. Intensity scale The intensity scale of our suspension system is calibrated in units of the spectrally weighted radiance for the photochemical hazard to the phakic eye LB 5. At this reference value, photoretinitis might be expected to occur as a result of the microscope illumination after a retinal exposure time totaling 10 minutes.
This applies to the exposure of a specific point on the retina with an uninterrupted illumination beam. In cataract surgery, instruments such as the phacoemulsification handpiece, the use of fluids in the eye, manipulation in and movements of the eye ensure that the illumination beam path is interrupted. These are factors which considerably increase the period after which photoretinitis might be expected to occur.
Reduction of the illumination of the surgical area to the extent required for the patient's safety and for clear microscopic visualization. Maximum reduction of the exposure of the patient's eye to light from surrounding light sources. These measures should help the surgeon to reduce the risk of phototoxic retinal injury in the patient.
This helps the surgeon to reduce the risk of phototoxic retinal injury in the patient. List of references H. Stiller, and B.

The standard equipment includes eyepieces with a magnification factor of Illumination system The illumination system has been designed for use in ophthalmology. A light guide directs the light from the light source in the suspension system to the surgical microscope. A retinal protection device is provided to protect the patient's eye from photoretinitis.
This device can be swung into the beam path if no red reflex is required. At the light source integrated in the suspension system, a GG eye protection filter can be swung into the beam path.
This filter markedly reduces the exposure of the patient's and surgeon's eyes to light. Adjust the intensity of the illumination of the patient's eye through the surgical microscope in such a way 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. Only use the retro-illumination contrast-enhancing stop see page 64 if the procedure requires a red reflex.
When operating on the eye, always use a GG protection filter to ensure that the patient's retina is not exposed to unnecessary blue radiation risk of retinal injury. The result is a significantly reduced illumination reflex on the cornea. Despite this, the image provides high contrast and a high information content. A slight opening approx.
