  • Page 8: Directives And Standards

    Safety The instrument described in this manual has been developed and tested in accordance with Carl Zeiss safety standards and with national and in- ternational regulations. A high degree of instrument safety is thus en- sured. We would like to inform you on the safety aspects involved in operating the instrument.

  • Page 9: Notes On Installation And Use

    Use this instrument only for the applications described. • Only use the instrument with the accessories supplied. Should you wish to use other accessory equipment, make sure that Carl Zeiss or the equipment manufacturer has certified that its use will not impair the safety of instrument.
  • Page 10 Make sure that all ”Requirements for operation” are fulfilled. • Go through the checklist. • Re-attach or close any covers, panels or caps which have been re- moved or opened. G30-1298-en VISU 200 Surgical Microscope Issue 2.0 Printed on 09. 11. 2006...
  • Page 11 • When operating on the eye, always use a GG 475 protection filter to ensure that the patient's retina is not exposed to unnecessary (blue) radiation (retinal injury). G30-1298-en VISU 200 Surgical Microscope Issue 2.0 Printed on 09. 11. 2006...

  • Page 12: When Using A Fundus Imaging System (E.g. Biom Ii)

    – Illumination characteristics (spectral composition) – Intensity of illumination – Angle of illumination – Focus of the light source – Exposure time to light G30-1298-en VISU 200 Surgical Microscope Issue 2.0 Printed on 09. 11. 2006...
  • Page 13 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 in- struments. Illumination characteristics (spectral composition) Studies on exposure of the eye to light of varying spectral composition date back to the early 1950s.
  • Page 14 Also, the surrounding light sources should not cause addi- tional strain to the patient's eye. Carl Zeiss has provided an answer to this problem in the form of a swing- in retinal protection device for insertion into the beam path of the surgical microscope.
