LEICA M844 OPHTHALMIC MICROSCOPE F40 FOR ADVANCED EYE SURGERY

The Leica M844 Microscope on F40 Stand belongs to the premium class of ophthalmic surgical microscopes and offers optimal solutions particularly for posterior and high-end anterior segment surgery.

Combined with the Leica M844 APO OptiChrome optics and direct halogen illumination, the system offers the best clarity, contrast, and sharp, true anatomical color images at safer low-light levels.

The result: a safer linkage between the diagnostic and surgical image. Features, such as the QuadZoom technology, the Double Wing Assistant Bridge, and HD recording – exclusively available from Leica Microsystems – make it furthermore the ideal microscope for Teaching Institutes and University Hospitals.

KEY FEATURES

Integrate retinal accessories and OCT imaging

The M844 has interfaces to accept and easily mount a row of retinal accessories, such as wide-angle observation systems and stereo image inverters. Furthermore, the M844 with an F40 floor stand can be provided with EnFocus intraoperative OCT for advanced eye surgery in the anterior and posterior segment.

Enjoy a truly bright and stable red reflex

This combination of direct halogen illumination and highly efficient optical transmission delivers a very bright, stable red reflex even under low light. The independent red reflex illumination Otto Flex II can be adjusted from diameters of between 4-35 mm to deliver light where it is most needed.

See more with less light

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.

Identical views for all observers
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.

Work in comfort
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.

Visualize and document in HD quality
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.

Intuitive Touch Screen Control Unit 

- Intuitive Control Unit: The touch panel offers intuitive control of all the Leica M844 functions. The control unit operation is simple and straightforward with many innovative features.
 - Everyone is an individual:  Customized start settings, such as illumination and magnification levels, are easily programmed into the control unit for up to 30 different users. By having a surgeon individual settings available at the touch of a button, the microscope is instantly ready for the next procedure and/or surgeon and the workflow of the surgical team is faster and more efficient.
-StepCycle for greater efficiency: Different levels of light, focus and zoom can optimize each phase of surgery. Making these adjustments today takes surgeons’ precious time. The automatic StepCycle function enables the surgeon to program predefined settings that are used throughout typical surgical procedures. After simple programming, a touch of a button on the foot pedal will activate the microscope predefined settings, step by step, during the procedure.
- Real-Time Video: With one touch of a button the control unit display becomes a general use, real-time video monitor, which allows an immediate and convenient view of the current surgical procedure for the operating room staff. For general video viewing there is no need for an extra video cart.
