Optics and Illumination
Razor-sharp, high-resolution imaging with brilliant, stable red reflex The unique combination of halogen and LED delivers bright, three-dimensional illumination and excellent red reflex. This innovation, paired with outstanding Leica optics, gives surgeons unprecedented vision to perform both cataract and retinal surgeries.
Leica optics
Images with natural color, superior depth of field, and high contrast deliver crucial information for successful ophthalmic surgery. The Leica M822 incorporates proven 800-series APO OptiChrome™ optics for high resolution of the smallest details.
Leica Low light concept
The extraordinary degree of light transmission and the high efficiency of the coaxial OttoFlex™ provide the surgeon with a bright, highly defined image, even at low light levels. The benefits for patient and surgeon are many: a more natural image for greater viewing comfort, reduced corneal glare, and greater efficiency – which can translate into better surgical outcomes.
Brilliant, Stable red reflex
With coaxial OttoFlex™ technology, the Leica M822 provides unsurpassed red reflex. Even the smallest cortical fragments can be clearly seen with minimal light. The large coaxial OttoFlex™ diameter provides stable red reflex throughout all steps of cataract surgery. Even if the eye moves intra-operatively during phaco, it remains in the field of illumination
An LED light source in a surgical microscope offers significant advantages over xenon and halogen sources. The nominal service life of an LED is up to 60,000 hours. In comparison, xenon and halogen lamps, but also fiber optic cables, need to be changed frequently. The reduced service requirement means fewer interruptions during surgery, more uptime, and smoother workflow.
Eco-Friendly Technology
As efficient lighting technology, such as LED, become more of the norm, they are changing the energy paradigm. LED light has a lower energy consumption, longer lifespan, and greater durability and reliability than other sources. These characteristics, combined with Leica‘s Low Light Concept, result in an environmentally-friendly microscope.
Carefully engineered
Leica Microsystems first introduced LED technology into ophthalmic surgical microscopes in 2008. With continued development and refinements, the Leica M822 microscope features the newest LED technology, which offers halogen-like light for a natural color rendering.
Cost effective
LED illumination adds value by reducing operating costs throughout the life of the microscope. But the real savings is this: fewer lamp changes mean fewer disruptions and less downtime, which enhances efficiency. The LED main light source provides many tangible and eco-friendly benefits in addition to a comfortable view.
Safer surgery
The Leica M822 microscope combines high transmission optics with a dual illumination system consisting of LED plus halogen. The result: a surgeon is free to adjust the optimum light balance, at the lowest possible light intensity, to achieve the best results in terms of red reflex, contrast, and recognition of important details.
Simple and versatile control
The user-friendly touchscreen control unit offers intuitive control of all microscope functions. Up to 30 surgeons can set their individual preferences, so the microscope is always ready for each surgeon. With the touch of a button, the screen switches between microscope control display and real-time video monitor (two-in-one display).
Multifunction Cabled and Wireless foot switches
To meet the needs of all users, four models of foot switches are available: cabled or wireless, 12-function or 16-function, which offers four additional freely programmable microscope or accessory functions. The Leica Wireless Footswitch offers maximum mobility for fast, easy adjustments.
Presets for repetitive procedures
StepCycle™ allows the surgeon to program and switch between predefined settings such as illumination, focus, and zoom for each step of a procedure. He or she can select these presets using the footswitch, which saves time and keeps the hands free for uninterrupted work
Standard and/ or High Definition Videos
The Leica M822 OpenArchitecture™ allows the capture of digital standard videos and still images with a variety of commercially available cameras and recording systems. With the optional Leica HD C100 high definition medical grade camera and the Med X Change video recording and documentation systems, surgical cases can now be recorded in best quality.
Modern Video Technology
The Leica M822 offers an ideal package for capturing and exchanging video information: State-of-the-art HD recording system with MPEG4 video compression and picture-in-picture function
• Leica HD C100 high definition medical grade camera with newest imaging technology
• Selection of unique Leica video adapters for intra-operative fine focus of a video with manual or remote control, and integrated zoom function
Download and Share
The Med X Mobile® application uniquely facilitates wireless transfer of HD videos and still images from the microscope capture system to the Apple® iPhone®, iPod Touch®, or iPad® within seconds.
With a USB cable, selected files can also be transferred to most Android™ devices. This allows cases to be transported, viewed, and discussed with colleagues or the patient’s family immediately after surgery.
Flexibility with Long Term Value
Flexibility today and compatibility tomorrow add up to a smart long-term investment The Leica M822 includes mechanical and electronic interfaces to accept and easily mount a wide range of accessories – now and into the future. These improve workflow, support better surgical outcomes, and allow new surgical techniques to be adopted..
Leica Slit Illuminator
This intra-operative precision surgical slit lamp is ideal for anterior and posterior segment surgery. Using the Leica slit lamp, both of the surgeon‘s hands are free for the operation, which allows a more fluid procedure.
Leica RUV800
The Leica RUV800 is the solution for panoramic viewing in retinal surgery. The integrated inverter gives the surgeon, assistant, and video camera the same upright view of the retina. The Leica M822 also fully integrates the commonly used wide-angle observation systems or stereo image inverters, such as the OCULUS SDI / BIOM®.
Leica DI C800
With the Leica DI C800 head-up display, images from digital sources, providing an XGA signal, can be projected directly into the surgeon‘s eyepiece. This cockpit-style display can show data precisely where the surgeon needs it. Using one microscope for cataract and vitreoretinal surgery is a very economical approach. It is easy to change the Leica M822 from one setup to the other.

Leica Keratoscope
The Leica Keratoscope is an integrated, cost-efficient aid to determine astigmatism in anterior segment surgery.
