9.7 Instructions for Focusing the
BIOM
®
5m
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.
Note
Adjust the ophthalmoscopy lens upwards for hyperopic eyes and
downwards for myopic eyes.
Attention
Risk of eye injury due to poor visibility conditions
If the surgeon works under poor visibility conditions, the use of intraocular
instruments can result in injury to the patient’s eyes.
When focusing the BIOM® 5, heed the following instructions.
Make sure that the microscope remains at this position (height) after
the surgical steps have been conducted at the anterior segment and
outside of the eye.
Before swinging it to the operating position, make sure that the BIOM®
5 has been set to the shortest overall length.
Before you begin to focus the BIOM® 5, check the distance from the
front lens to the patient’s eye.
Monitor the distance between the front lens and the eye while focus-
ing the BIOM® 5.
