When using a fundus imaging system (e.g. BIOM 3)
When using a fundus imaging system (e.g. BIOM 3 from the company Oc-
ulus) 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 suspension system
arm.
Only use accessories expressly certified by the manufacturer for combi-
nation with the surgical microscope described in this manual.
Warning!
•
With the fundus imaging system swung out of position, always position
the microscope body in such a way that index dot (1) of the micro-
scope's focus is in the middle of triangle (2) of the marking.
•
Select a medium magnification (e.g. 1.0).
•
Lower the surgical microscope toward the surgical field until you see
the patient's cornea sharply defined.
•
Turn the locking lever for limiting the downward movement clockwise
as far as it will go and check without the patient that the suspension
arm cannot be lowered any further.
•
It is vital that you read the user's manual on the fundus imaging sys-
tem used (e.g. BIOM 3 from the company Oculus).

General
Several papers

publications reveals five aspects of particular concern:
–
Illumination characteristics (spectral composition)
–
Illumination intensity
–
Angle of illumination
–
Focus of the light source
–
Exposure time to light
