2 Safety Instructions
4 / 34
Attention
After the BIOM 4 has been swung in into the working position, the following must not be
performed during the proper use:

to use the rough adjustment mechanism of the microscope support under any
circumstances (since the mechanism is not designed for precisely controlled
movement)

to change the height position of the microscope support by mechanical or
motorized means whilst above the operating area

Safety instructions for focusing the BIOM 4

Attention
The following points must be heeded when focusing the BIOM 4:
 The BIOM 4 is only needed for visualization of the posterior segment of the eye.
After performing the operation steps at the anterior segment of the eye and outside

of the eye, the microscope should be remaining at this position (height).
Before swinging it to the operating position, make sure that the BIOM has been set

to the shortest overall length.
Before you begin to focus the BIOM 4, check the distance from the ophthalmoscopy

front lens to the patient's eye.
Monitor the distance between the front lens and the eye while focusing the BIOM 4.

 Make sure that the ophthalmoscopy front lens does not come into contact with
the eye.
The microscope must not be adjusted in height, nor must the focusing function of

the microscope be used while the BIOM is being focused.
For BIOM 4c only (focusing done by electric motor):
 Only use the motorized BIOM focusing function when the ophthalmoscopy lens is
far enough away from the eye.
The motorized focusing function of the BIOM 4c may only be used by the surgeon,

when this distance is simultaneously monitored.
It must be ensured that the operator can stop the motorized focusing function at

any time.
