Practical Information for Use

Attention
Risk of eye injury as a result of uncontrolled head movements of the
patient.

Take suitable measures to suppress uncontrolled head movements of
the patient during the surgery.

Avoid any contact of the front lens with the cornea.
If the lens comes into contact with the cornea, the image immediately
becomes blurred.

In an extreme emergency, e.g. uncontrolled downward movement of
the microscope:
Stop with the Emergency Off button.

 Pull or move the complete surgical microscope upwards.
Tilt the BIOM® 5 out of the beam path.


After a contact with the eye, swing the BIOM® 5 out, or slide the safety
rod upwards to facilitate cleaning of the optics, so that you can clean
the lens with a sterile swab.

Make sure that the cornea is sufficiently moistened with a suitable
solution. This will prevent damage to the cornea and will give you the
optimal view into the eye.
Adjustment of the microscope's focus while the BIOM® 5 is in use acts as a
field diaphragm. The greater the distance between the eye and the
microscope, the smaller the angle of observation. This leads to the so-called
"keyhole effect".
Focusing on the BIOM® 5m is done manually with the adjusting wheel and
can also be done by a sterile assistant, who follows the surgery via a co-
observer viewer.

For BIOM® 5c only:
Focusing of the BIOM® 5c is done solely by the surgeon by means of the
combination foot switch while observing through the microscope.
Note
Adjust the ophthalmoscopy lens upwards for hyperopic eyes and
downwards for myopic eyes.
