UNIQUELY LEICA

Crisp and sharp
Leica’s APO OptiChrome M844 optics provide the highest resolution to see even the smallest anatomical details.

Same view, same light
Leica’s QuadZoom gives both the surgeon and assistant 100% of the llumination and the same magnification.

Enhanced safety for the patient and surgeon
Leica's exclusive direct illumination system offers impressive clarity, contrast and color at safe low-light levels.

Leica introduces the original APO OptiChrome
Providing an extraordinary degree of light transmission for maximum detail recognition is critical for all types of ophthalmic microsurgery. For the posterior segment surgeon, where availability of light is limited, a high degree of light transmission is essential. For refractive and anterior segment surgery, low light is always better for the patient.

Expect only the highest standards in optics from the Leica M844

• Sharper and crisper image
• Higher light transmission
• Natural colour fidelity
• Outstanding depth of focus
• Higher contrast

Efficient illumination
By utilising four separate beam paths through the same common zoom system, the Leica QuadZoom delivers 100% APO OptiChrome stereovision and 100% illumination for both the main surgeon and the assistant.

2 × 2 views always synchronized
By putting both pairs of beam paths through one common zoom system, as the surgeon changes magnification, the assistant's view is perfectly synchronized with the surgeon's view.

Low light supports patient and surgeon safety
With two bulbs and two prisms, the Leica M844 creates true three-dimensional illumination. Using a focused, direct illumination system instead of fiber optics, the Leica M844 takes a ray of light and projects a crisp, sharp and homogeneous image even at very low light levels. This combination of direct halogen illumination and highly efficient optical transmission helps protect the eyes of patient and surgeon alike.

See things in a different light
OttoFlex II, an integrated independent illumination system, gives a brilliant red reflex even in low light conditions and enhances the view's contrast. Difficult anatomical conditions, such as small pupils or very advanced cataracts are more easily visualised through this unique system. Continuously adjustable from 4 mm to 35 mm diameter, OttoFlex II places the brightness where the surgeon needs it most.

Intuitive control unit
The touch panel offers intuitive control of all the Leica M844's functions. The control unit’s operation is simple and straightforward with many innovative features.

Everyone is an individual
Customised 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’s 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's predefined settings, step by step, during the procedure.

Real-time video
With one touch of a button the control unit's 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.

Leica F40 space saving stand with extended net reach
The Leica M844 F40 has a small footprint but long reach which makes it easy to position anywhere around the operating table. Four large, fully pivoting casters and an easy to grasp handlebar make the microscope effortless to transport into and out of position.

Auto Reset and it's ready to go
When the surgeon pushes the swingarm up after each procedure,all the microscope functions automatically reset and the microscope is ready for the next case. A real time saver for the operating room staff and peace of mind for the surgeon.

Focus Lock – for quick movement in and out of the operative site
Focus Lock allows the surgeon to move the microscope in and out of position laterally. With the microscope staying on the same focus plane, the surgeon does not have to waste precious time refocusing to continue his procedure.

Easy side-to-side quick change for the assistant
Changing the assistant's position from one side to the other can be done quickly and easily without removing any parts. Simply lift the main surgeon's binoculars and rotate the assistant's bridge. No parts to drop or damage!

The UltraLow III for ideal eyepiece-to-field distance
The UltraLow III binocular eyepiece tubes drop lower than conventional binoculars, which compensates for stacking auxiliary accessories on the optics, such as inverters or laser shutters.The surgeon now works in comfort.

ErgonOptics for individual comfort and concentration
Every surgery requires the highest level of concentration from the surgeon and his or her surgical team. The physical comfort of the surgeon is critical to this concentration. Leica provides a large selection of binoculars and three different objective lens types to meet each individual surgeon's physical requirements. No other
microscope system offers this range of surgeon and assistant binoculars and objective lenses.

Independent choice of wide-angle observation accessories
The Leica M844 is designed to accept the integration of wideangle observation systems or stereo image inverters. Leica Microsystems' own solution, the Leica RUV800 with integrated inverter, gives the surgeon, assistant, and video camera the same upright view of the retina. In addition, when integrating the Oculus SDI/BIOM system, the surgeon can control its functions through the Leica M844's 16-function foot pedal therefore the system can be fully controlled by a single foot pedal instead of two.
