Page MISU Operation Roll-over procedure Use the "Roll-over procedure" to select the required function in the default sequence of the above table. A beep is emitted when the new position has been saved. To move to a stored focus position, press the key config- ured for this purpose only briefly less than 2 seconds. Rollover Select the function required using a rollover run in the sequence defined in the above table. Look through the eyepieces of the binocular tube. Adjust the eyepieces in such a way that you can see both the edge of the field of view and the microscope image sharply.

Make sure that drapes do not cover the grid. This can lead to overheating of the lamp modules and to lamp failure. For example, drapes could be covering the grid. This can lead to overheating of the lamp module and to lamp failure. Note: Yellow indicator lamp 4 lights when the lamp has failed, or if the lamp module is defective. Note: When the manual function has been activated, all electrical control sys- tems are inoperative.

The lamp brightness is automatically adjusted to a fixed setting. Page Failure Of Magnetic Brakes MISU Operation Failure of magnetic brakes If the magnetic brakes fail magnetic brakes are locked , you can manu- ally position the articulated arm including the microscope by overcoming the locking effect of the magnetic brakes.

The connector is located under the cover of the suspension arm. The illu- mination remains on. To ensure opti- mum performance and safe working order of the instrument, its safety must be checked once every 12 months. We recommend having this check performed by our service representative as part of regular main- tenance work. Switch off illumination on suspension system. Illuminate surgical field using an OR illuminator. Remove the cause of over- microscope not working.

When the lamp module has cooled down, the illumination switches on again. Yellow LED above microscope are inoperative. Suspension arm is in hori- Suspension arm still locked. When the lamp module has cooled down, the illumi- nation switches on again. Defective lamp control Switch off illumination on system.

Contact service dept. Aged xenon lamp. If you change the lamp shortly after it has failed, the lamp will still be very hot. Wear heat-protection gloves to avoid burns! Note: If both halogen lamps 4 and 5 fail during surgery, insert an available backup lamp module. Make sure you do not touch the lamp bulb 7 or the interior of the reflector 6. Fill in the enclosed return card and send the old lamp module to the nearest Zeiss service agency.

Page Care Of The Unit To protect the eyepiece optics from fogging, we recommend using an anti-fogging agent. Note: Anti-fogging agents provided by eyecare professionals for use with eye- glass lenses are also suitable for Zeiss eyepieces.

The measurement process runs automatically. You start directly via the touchscreen and choose from single or multiple measurements. You also have the option of initiating a test puff to prepare your patients for the examination. The results appear directly on the monitor.

Alternatively, you can print out the results with the integrated thermal printer, or export via the serial interface. Add to Wishlist. Product added! Browse Wishlist. 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 using a fundus imaging system e. BIOM II from the company 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 stand arm.

Only use accessories expressly certified by the manufacturer for combination with the surgical microscope described in this manual. Several papers have been published dealing with the problems of phototoxicity during eye surgery. 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 instruments.

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. The majority of researchers suggest that the surgeon should use the lowest light intensity necessary to guarantee good viewing during surgery. Carl Zeiss has addressed this concern by providing 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.

Carl Zeiss strongly discourages the use of xenon or other high-intensity light sources in ophthalmology. 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:. 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 the peak intensity of an even and extended light source such as a fiber guide. This is the reason why fiber optic illumination is used in surgical microscopes from Carl Zeiss. 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. At this reference value, photoretinitis might be expected to occur from the surgical microscope light source in a total retinal exposure time of 10 minutes. This applies to the exposure of a specific point on the retina with an uninterrupted illumination beam.

In a cataract procedure, instruments such as the phacoemulsification handpiece, the. Such factors would be expected to significantly extend the time at which photoretinitis might occur. These measures should help the surgeon to reduce the likelihood of phototoxic retinal injury. These measures help the surgeon to reduce the risk of phototoxic retinal injury.
