Operating microscope

New generation of microscopes for ophthalmic surgery with innovative lighting system
The Leica microscope brings high performance and precision to ophthalmic surgeries thanks to Leica 8 Series optics and an innovative dual illumination system: LED for the main light and a halogen lamp for an unrivaled and stable red reflex.

Optics and lighting
The unique combination of halogen and LED light sources provides bright, three-dimensional illumination and excellent red reflex. This innovation, combined with Leica's unique optics, gives surgeons unprecedented visibility to perform operations on both the anterior and posterior segments of the eye.
Leica optics
Images with natural color, extreme depth of field and high contrast convey all the important information for successful operations. Leica includes proven 800-series high-definition optics APO OptiChrome™

Leica Low Light Intensity Concept
The exceptional light transmittance and high efficiency of the OttoFlex™ coaxial illumination system provides the surgeon with bright, highly detailed images even at low light intensity levels. This has many benefits for the patient and the surgeon: a more natural image for better viewing, reduced corneal glare, greater efficiency - all this helps to achieve a better surgical outcome.
The bright, stable red reflex of the Leica M822 with coaxial OttoFlex™ technology provides an unrivaled red reflex, making the smallest fragments of the lens masses clearly visible even in the lowest levels of illumination. The large diameter of OttoFlex™ ensures a stable red reflex throughout all stages of cataract surgery, including eye movement.
LED lighting - reliable, safe, environmentally friendly and economical LED lighting offers a number of significant advantages over xenon and halogen lighting:
• the most natural color rendition;
• the ability to freely adjust the optimal light balance at the lowest possible light intensity to achieve the best red reflex, contrast and detail;
• nominal service life of LED elements is 60,000 hours with minimal power consumption;
• reduction in the need for service;
• reducing the number of breaks during surgery;
• significant increase in uptime.

Ergonomics and ease of control
Comfortable work allows the surgeon to better concentrate on the operation. The Leica M822 not only offers surgeons better images, but also a more comfortable day-to-day work experience thanks to natural microscope positions and less strain and fatigue.

Intuitive microscope
The Leica's controls, settings and movements are very clear, making the microscope easy to use. The intuitive controls and interface of the microscope ensure ease of use, logical workflow, and the ability to choose personal preferences. Using a Leica, the surgeon focuses on the patient and the operation, not the microscope settings

For your eyes only
ErgonOptics™ is a Leica system that provides the widest range of interchangeable lenses and binoculars to suit each surgeon's individual requirements. For example, the unique UltraLow™ II binocular allows the surgeon's viewpoint to be lower than other binoculars to compensate for the height of installed ancillary accessories.

Various floor and ceiling tripods
With the ability to be mounted on either of two compact floor stands or two compact ceiling stands, the Leica M822 microscope is very easy to place and move in any size operating room. The long support rod allows you to quickly adjust to the operating field, ensuring a stable image position throughout the entire operation.

Auto reset and the microscope is ready for use again
To quickly reset all current microscope settings, simply lift the support rod up.

Simplified access from the temporal side
Leica Microsystems has developed the world's first rotating beam splitter for temporal access in cataract surgery. The assistant's easy and quick repositioning of the binoculars saves time between procedures, increases efficiency in the operating room, and minimizes the possibility of binocular damage. For maximum flexibility, the Leica video adapter connector is conveniently located on the rear panel.
Presets for repeating procedures
The StepCycle™ feature allows the surgeon to program and switch between preset settings such as light level, depth of focus, and magnification level for each step of the procedure. The surgeon can switch between these presets using a foot pedal, saving the surgeon time and freeing his hands.

Easy and flexible control
The user-friendly touch control unit offers intuitive control of all microscope functions. Up to 30 surgeons can create their own custom settings, so the microscope is always ready for every surgeon. When you press the center button, the screen switches between the microscope control monitor and the video monitor.

Multi-function wired and wireless foot switches
To solve most user problems, Leica offers two options for foot switches: wireless 12 or 14-function pedals with the ability to freely reprogram the assignments of each element to a specific function of the microscope or module connected to it.
Full image control
When a surgeon wants to share photos or videos with his colleagues in the operating room in real time, show them an interesting case, document the progress of an operation or treatment - high-definition video and the use of mobile devices are now becoming the gold standard.

High Definition Video
Leica OpenArchitecture™ allows you to capture digital video and photos from cameras and recording systems from different manufacturers. With the optional recording system, all operations can be recorded in high definition. The user-friendly system can be mounted on Leica tripods; The monitor can be rotated to a convenient position for viewing.

Modern video technologies
Leica offers a complete package of functions for recording and sharing video information:
• the latest HD video recording system with video compression in MPEG4 format and the “picture-in-picture” function;
• monitor bracket with four movable joints for easy viewing;
• a wide selection of unique Leica video adapters with intraoperative aseptic precision focusing with manual or remote control and integrated zoom function.
