With the highest level of optics and the latest technology, the Leica M844 microscope sets the premium standard for ophthalmic surgical microscopes. The unique 4-channel Leica QuadZoom ™ system provides the surgeon with a completely independent optical channel, which, in combination with excellent optics, allows for excellent image quality in any operation. The combination of the path of the optical systems of the surgeon and the assistant in one scheme allows to achieve ideal synchronization of the magnification and diameter of the field of view for the surgeon and the assistant. The assistant can individually fine-tune the focus separately from the primary surgeon.
