Safety The instrument described in this manual has been developed and tested in accordance with Carl Zeiss safety standards and with national and international regulations. A high degree of instrument safety is thus ensured. We would like to inform you on the safety aspects involved in operating the instrument. This chapter contains a summary of the most important precautions to be observed.
Safety Notes on installation and use Safe working order • G-30-1439-en Do not operate the equipment contained in the delivery package in – explosion-risk areas, – the presence of inflammable anesthetics or volatile solvents such as alcohol, benzine or similar chemicals. • Do not station or use the instrument in damp rooms. Do not expose the instrument to water splashes, dripping water or sprayed water. • Immediately unplug any equipment that gives off smoke, sparks or strange noises.
Safety • Only personnel who have undergone training and instruction are allowed to use this instrument. It is the responsibility of the customer or institution operating the equipment to train and instruct all staff using the equipment. • Keep the user's manuals where they are easily accessible at all times for the persons operating the instrument. • Never look at the sun through the binocular tube, the objective lens or an eyepiece.
Safety • Pay special attention to warning symbols on the instrument (triangular warning signs with exclamation marks), labels and any parts such as screws or surfaces painted red. For every use of the instrument G-30-1439-en • Avoid looking directly into the light source, e.g. into the microscope objective lens or a light guide. • Any kind of radiation has a detrimental effect on biological tissue.This also applies to the light illuminating the surgical field.
Safety When using a fundus imaging system (e.g. BIOM II) When using a fundus imaging system (e.g. 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.
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 instruments. Illumination characteristics (spectral composition) Studies on 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.
Safety This is the reason why fiber optic illumination is used in surgical microscopes from Carl Zeiss. 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.
Safety use of fluids in the eye, manipulation and movement of the eye, among other factors, result in the interruption of the illumination from the surgical microscope light source. Such factors would be expected to significantly extend the time at which photoretinitis might occur. In conclusion Carl Zeiss recommends: – Use of the GG 475 eye protection filter. – Reduction of the illumination of the surgical area to the extent required for the patient's safety and for microscopic visualization.
Safety Warning labels and notes Caution: Observe all warning labels and notes! If any label is missing on your instrument or has become illegible, please contact us or one of our authorized representatives. We will supply the missing labels.

Description VISU 200 BrightFlex™ Surgical Microscope Intended use The VISU 200 BrightFlex™ surgical microscope has been designed for surgical procedures in the field of ophthalmology, i.e. the microscope meets the special requirements of this discipline. Description of the modules The VISU surgical microscope is comprised of the following modules: 1 X-Y coupling The X-Y coupling allows fine, motorized positioning of the surgical microscope in a horizontal plane. The range of travel is 40 mm x 40 mm.
Description 1 G-30-1439-en OPMI® VISU 200 BrightFlex™ Surgical Microscope Issue 3.0 Printed on 21. 11.
Description 2 Support arm for the surgical microscope The support arm incorporates a tilt device. 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 +180° to -180° (+ 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.

Description To protect the patient's eye against photo-retinitis, a retinal protection device is provided. This device can be swung into the illumination beam path, if no red reflex is required. At the light source integrated in the stand, a GG 475 eye protection filter can be swung into the illumination beam path. This filter markedly reduces the exposure of the patient's and surgeon's eyes to radiation.
Description G-30-1439-en OPMI® VISU 200 BrightFlex™ Surgical Microscope Issue 3.0 Printed on 21. 11.
Description 4 0° assistant's microscope The assistant's microscope is an integral part of the VISU 200 BrightFlex™ surgical microscope, i.e. it cannot be separated from the main microscope. The assistant sees the same image as the main surgeon. The system's excellent image quality is also available to the assistant. 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.
