OCULUS BIOM® 5
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.
Description
Highlights
Slim and sleek
The slim and open design is lightweight and increases accessibility for the surgeon’s hands and instruments as well as reprocessing. Space consumption in the operating field is also minimized.

Optimized Surgical Efficiency
The new reduction lens is designed to optimize the view of the retina and the limbus without the need to refocus during extraocular phases of surgery.
Precision Engineered for Maximum Accuracy
OCULUS’ high design and manufacturing standards ensure greater stability and precision. Selected materials, including Titanium, offer increased durability, with excellent resistance to today’s rigorous and sometimes harsh sterilization methods.

Wide-Field in High Definition
The new OCULUS BIOM® WiFi HD lens is designed to provide superior clarity with wide-angle viewing. This unique design also provides high definition during high magnification, reducing the necessity of a separate lens for macula work.
Compatibility and continuity
The BIOM® 5 is interchangeable with most accessories of the former BIOM® 3 and BIOM® 4 versions.
Features
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.
Intelligent
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.
Intelligent activation of the SDI® 4c
BIOM® 5c (with electronic focus)
When used with the SDI® 4c, the BIOM® 5c offers the convenience of electronic foot pedal focusing and intelligent and automatic image inversion.
BIOM® Connecting Spacer
If your microscope already incorporates a stereoscopic diagonal inverter, you don’t have to miss out on the benefits of the OCULUS BIOM® 5c and BIOM® 5cl. Ask the OCULUS team about the BIOM® Connecting Spacer.
