Binocular Indirect Ophthalmomicroscope

The BIOM® 5 is the ideal complement to the SDI® (Stereoscopic Diagonal Inverter). The BIOM® 5 enables wide-angle observation of the fundus during vitreous surgery. The observation unit BIOM® can be mounted in a matter of seconds and can be swung into the beam path when needed.

Efficiency meets function

Surgeons appreciate the easy handling of the new BIOM® 5. While observing the vitreous and the fundus, the BIOM® 5 is aligned coaxially with the operating microscope.  During extraocular phases of surgery, it is swung out of the observation beam while the inverting action of the SDI® is neutralized:  automatically, by a surgeon controlled footswitch, or manually.


The convenience of automatic inversion provided by the SDI® 4c ensures the surgeon's view is always orientated properly. This is accomplished by OCULUS´ patented design, utilizing a fully autoclavable micro switch.
