M844 Ophthalmic microscope for advanced eye surgery

Leica Optics have superior light gathering abilities. Sharp, brilliant, true anatomical color images with excellent depth of field can be obtained even with very low or no microscope illumination. This helps protect the eyes of both the surgeon and patient, but still enables clear visualization of small details.

Select, modify, and load the surgeon preferences using the intuitive touch screen user interface of the M844.

With two bulbs and two prisms, the M844 delivers homogenous illumination for a true three-dimensional vision with high depth perception.

QuadZoom technology with four separate beam paths in the zoom system of the M844 provides an identically bright stereo view for both the main surgeon and the assistants. No manual adjustment by the teacher is necessary. Furthermore, the optional double wing assistant bridge can give a full stereo view with the same magnification to two assistants.

Conventional microscope (left image): The main surgeon loses up to 20% of the light to the video camera. M844 (right image): the main surgeon benefits from 100% light, even if a video camera is added. QuadZoom features four separate beam paths - two for the surgeon/teacher and two for the assistant/student. The result: identical magnification and stereo view for all observers.

The M844 ophthalmic microscope offers various features to enhance the comfort of both the surgeon and assistant, as well as to support an ergonomic workflow. For example: individually adjustable binocular tubes such as the UltraLow III binocular tube, wireless footswitch, StepCycle, and Auto Reset function.

M844 fully integrates the most used wide-angle observation systems or stereo image inverters such as the BIOM 5 and SDI 4 from OCULUS. The surgeon can operate these vitreoretinal accessories via footswitch.

Combine the M844 ophthalmic microscope with the HD C100 medical video camera from Leica Microsystems to record and easily share procedures in HD quality. For more comprehensive documentation, the M844 is also compatible with the EVO 4K recording and documentation system from Med X Change.
