When using a fundus imaging system (e.g. BIOM II)

When using a fundus imaging system (e.g. BIOM II 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 stand arm.

Only use accessories expressly certified by the manufacturer for combi-

nation with the surgical microscope described in this manual.

Caution!

• 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 towards the surgical field until you see

the patient's cornea sharply defined.

• Turn the screw for limiting the downward movement clockwise as far

as it will go.

• It is vital that you read the user’s manual on the fundus imaging sys-

tem (e.g. BIOM II from the company Oculus).

Phototoxic retinal injury in eye surgery

General

Several papers have been published dealing with the problems of photo-

toxicity during eye surgery. A comprehensive review of these publications

reveals five aspects of particular concern:

– Illumination characteristics (spectral composition)

– Intensity of illumination

– Angle of illumination

– Focus of the light source

– Exposure time to light

Risk of collision!
