Safety instructions for focusing the BIOM 4
Attention
The following points must be heeded when focusing the BIOM 4:
The BIOM 4 is only needed for visualization of the posterior segment of the eye. After performing the operation steps at the anterior segment of the eye and outside of the eye, the microscope should be remaining at this position (height). Before swinging it to the operating position, make sure that the BIOM has been set to the shortest overall length. Before you begin to focus the BIOM 4, check the distance from the ophthalmoscopy front lens to the patient’s eye. Monitor the distance between the front lens and the eye while focusing the BIOM 4. Make sure that the ophthalmoscopy front lens does not come into contact with the eye. The microscope must not be adjusted in height, nor must the focusing function of the microscope be used while the BIOM is being focused.
For BIOM 4c only (focusing done by electric motor):
4 / 34
Only use the motorized BIOM focusing function when the ophthalmoscopy lens is far enough away from the eye. The motorized focusing function of the BIOM 4c may only be used by the surgeon, when this distance is simultaneously monitored. It must be ensured that the operator can stop the motorized focusing function at any time.

Mode of operation of the BIOM 4
The BIOM 4 is used in conjunction with an SDI (Stereoscopic Diagonal Inverter) to erect the image for non-contact, wide-angle observation of the fundus and vitreous body. The combination of operating microscope and the optical components of the BIOM 4 allows examination of the vitreous body in the posterior chamber under stereoscopic

5 Device Description
conditions. The BIOM 4 works as an indirect ophthalmomicroscope without corneal contact during the surgery. The patient’s eye ball can be moved freely during the surgery. Peripheral fundus portions are thus easy to examine. This combined optical system achieves a fundus view of up to 120° in total. The optical system of the BIOM 4 consists of the reduction lens and the front lens. The reduction lens provides a virtually constant distance between the patient’s eye and the operating microscope when the BIOM 4 is swung in or swung out. Individually adjusted to the respective operating microscope, the microscope objective’s focal distance is reduced. The position of the reduction lens with respect to the operating microscope is preset. The height adjustment of the front lens is used for focusing the BIOM image. The distance between the operating microscope and the front lens is set using the adjusting wheel at the BIOM 4. For BIOM 4c only:
Press the combination foot switch to focus by means of the electric motor. This height adjustment of the front lens brings the fundus image into the focal point of the microscope objective. As the image is completely reversed when the BIOM 4 is used, safe use is only guaranteed in conjunction with a stereoscopic diagonal inverter (SDI). The SDI rights the complete image reversal and can be switched on and off as required.
5.3
To use a BIOM 4c on SDI 3c
If this BIOM 4c (4-pin plug) should be used on the former SDI 3c (2-pin socket) version, a plug adapter (item no. 54406) is needed. This plug adapter should be connected with the 2-pin socket in the SDI housing. The sterile plug of the connecting cable of the BIOM 4c then needs to be connected with the adapter plug. For dismantling the BIOM 4c, grip the plug of the BIOM 4c connecting cable and pull it out of the adapter plug.
Attention
For use of a BIOM 4c, the adapter plug (item no. 54406) has to be removed from the SDI 4c housing.

Operation
6.1
First-time operation
Please remove the BIOM 4 and its accessories from the packaging and dispose of the latter in the proper manner. The BIOM and all sterilizable accessories must be cleaned, disinfected and sterilized prior to initial use and before each subsequent use. As part of an optical system, the BIOM 4, and the operating microscope too, must be handled with care and must not be subjected to vibrations, blows or be allowed to get dirty.
6.2
Daily operation
To mount the BIOM 4, an adapter is needed, which is customized to the type of operating microscope that is being used. If necessary, the adapter must be supplemented with an intermediate piece or a mounting fixture. Installation and instruction in the use of the BIOM 4 and its accessories will be done by an Oculus employee or by a duly authorized Oculus representative. A part of the mounting fixture generally remains installed at the microscope. Just like the BIOM 4 and its components, the detachable adapter plate must be cleaned, disinfected and sterlized prior to use. If, however, you do have to remove the mounting fixture for any reason, please proceed as shown on the assembly diagram provided with the adapter. When assembling dovetail connections, first visually check that the connection sits properly. Then tighten the knurled screw hand-tight. If the connection is correct, the dovetail connection will have no play. Check this by gently rocking the connection before you begin mounting any of the other attachments.
Attention
Detachable connections can be a source of danger if used incorrectly.

Î
Insert the reduction lens into the lens holder so that the side lugs sit in the recesses. Î Turn the reduction lens clockwise until the bayonet catch engages. It is thus held at that position. Î Insert the front lens into the adapter provided for that purpose. Here again, a detent prevents the lens from falling out. This detent must be overcome when inserting the lens. Make sure that the lens is properly aligned. For the BIOM 4c only: Î Mount the drive belt at the BIOM 4c. For all three pulleys, the drive belt should run
in the recesses provided for that purpose, otherwise the function cannot be guaranteed. When inserting the belt, begin at the groove at the bottom end of the adjusting wheel; this will make handling easier. Î
Now, using minimal effort, slip the BIOM 4 onto the adapter plate until it reaches the limit stop. You must thereby overcome a detent that secures the connection.
Attention
Make sure that the BIOM 4 has been slipped on up to the limit stop. That is the only way that safe handling and proper centering of the image are possible.

When using the BIOM 4 focusing function, heed the following points:
16 / 34
Before swinging it to the operating position, make sure that the BIOM has been set to the shortest overall length. Before starting the focusing process, check whether the ophthalmoscopy front lens is far enough away from the patient’s eye. Make sure that the front lens does not come into contact with the eye. While focusing the BIOM, the working height of the microscope must never be adjusted, nor must the focusing function of the microscope be used.
Instruction manual BIOM 4 (G/54400/0109/en)
7 Use of the BIOM 4
For BIOM 4c only (focusing done by electric motor):
Only use the BIOM 4c’s motorized focusing function when the front lens is far enough away from the patient’s eye. The surgeon may only use the motorized focusing function when the distance between the ophthalmoscopy front lens and the eye is simultaneously monitored. It must be ensured that the operator can stop the motorized focusing function at any time.
Attention
After the BIOM 4 has been swung in into the working position, the following must not be performed during the proper use: Î
to use the rough adjustment mechanism of the microscope support under any circumstances (since the mechanism is not designed for precisely controlled movement). Î to change the height position of the microscope support by mechanical or motorized means whilst above the operating area. Î to change the patient´s position by raising/lowering the OP-table.
Visualization of the posterior eye segment After all preparations for surgery in the posterior segment have been completed proceed as follows, without changing the microscope position! Î
Î
Use a suitable endoillumination. Swing the BIOM 4 into the beam path of the microscope. Lift up safety insertion and only release it again when the swung-in end position has been reached. The lens slides down to its designated position. This position has been reached when the control marks are fully visible. Turn off the microscope illumination. Activate the SDI to right the complete image reversal.
Î
For BIOM 4c and SDI 4c only:
If the BIOM 4c is swung out of the beam path the inverter function is not activated. While swinging the BIOM 4c into working position the SDI 4c is activated automatically. The position switch on board of the BIOM 4c thus operates the re-inverting function. If another status of the inverter is desired, the SDI 4c can be optionally operated via a combi foot switch.
Î Î Î
Î
At a low microscope magnification: Begin initial focusing of the BIOM 4-image by turning the BIOM 4 focus adjusting wheel. Î Magnify the image section by actuating the focus foot switch at the microscope.
