The human eye is an extremely delicate organ, and so performing ophthalmic surgery requires the ability to monitor progress on a micro-level. Ophthalmic operating microscopes are designed to provide high contrast and detailed imaging of all regions of the human eye. When choosing an ophthalmic operating microscope, it is important to pay attention to the type of optics employed. An apochromatic lens (or apo) will provide high light transmission, permitting high-quality imaging at lower light intensities. Certain models of ophthalmic surgery microscope provide multiple lighting options such as the ability to switch between halogen and xenon. An ophthalmic surgical microscope can either be fixed or adjustable, and some models provide a second “observer” set of binoculars, some of which can independently adjust the focusing mechanism.

| Description | The new Leica M501 TTS perfectly meets the needs of trainees as well as trainers. The microscope offers brilliant resolution, large depth of field with outstanding stereopsis and natural color reproduction. It offers many and diverse solutions for co | Leica M501 combines quality and precision and has brand new illumination concept which grants an easily achievable, perfectly stable RedReflex. It gives a brilliant resolution and increased depth of field, and has a built-in prism for glowing red | Leica M680 has been specially designed for microsurgery. It is also known as the "two-in-one-microscope". | The Leica M844 F40 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 | Leica MC1 is a stand that is perfectly designed for use with the M500 N microscope system. It is also easily and readily upgradeable in the future. |
| Features | Leica M501 optics. Compact table stand system for ergonomic positioning. Magnification display and reset button for focus. Speed adjustable with automatic and manual reset function. Tilt mechanism with integrated fine adjustment. Coaxial illumination with homogeneous illuminated field. Red Reflex illumination integrated. Sterilely operable jalousie-diaphragm for continuously fading of the coaxial light for optimal three dimensional fundus reflex for individual criteria. Quick-change lamp mount. Control unit with intuitive controls for zoom, focus and light intensity. ErgonOptic means a wide range of observation options for comfortable viewing and fatigue free viewing like the ultra low binocular tube. Foot-/handswitches with 6 functions. Asepsis for all controls. | Compact stand system for easy and rapid positioning. New swingarm with precision bearings for smooth movement. Small, stable base with large lockable casters. Motorized XY-unit, speed adjustable with automatic and manual reset function. Tilt mechanism with integrated fine adjustment. Coaxial illumination with homogeneous illuminated field. Red Reflex illumination integrated. | Perfect 3D effect, superb resolution and brilliant contrast. Four beam paths. Constant light intensity over the whole magnification range that works even when the microscope is switched off. Proportional speed (the adjustment speed of the focus drives), and swivelling and tilting joints which are dependent on the selected magnification. | - See more with less light
Leica Optics have superior light gathering ability. Sharp, brilliant, true anatomical color images with excellent depth of field are obtained under limited or even no microscope illumination. The result: better detail recognition, added patient safety, and fatigue-free viewing for the surgeon.
- QuadZoom: The teaching solution
Only Leica's QuadZoom™ technology features four separate beam paths in the same zoom system. No manual adjustment by the teacher is necessary. Leica's Double Wing furthermore allows two students/assistants to have full stereo view at the same magnification.
- Work in comfort
The Leica M844 F40 offers various features to enhance the surgeon's and assistant's comfort and to support an ergonomical workflow. For example: individually adjustable binocular tubes such as the UltraLow™ II binocular tubes, Leica Wireless Footswitch, Two-in-One display, StepCycle™, and Auto Reset function.
- High-definition documentation
The Med X Change HDMD™ All-in-One (AIO), a compact, integrated HD digital recording system, provides stunning, high-quality videos, and still images. The system is exclusively available from Leica Microsystems. Additionally, surgical cases can be wirelessly transfered to an Apple® device with Med X Mobile.
- Integration of retinal accessories
Leica Microsystems' surgical microscopes are designed to integrate the most commonly used wide-angle observation systems and stereo image inverters. They are also provided with a quick mount interface to comfortably and quickly install and remove e.g. the Leica slit lamp.
- True Red Reflex
The double beam stereo illumination and Leica's large OttoFlex™ II illumination diameter enable true three-dimensional vision, and better Red Reflex stability and brightness. The result: increased depth of field, less XY-centering and refocusing required, brightness adjustable where it is needed most.
| High performance 300 Watt xenon lamp. Ergonoptic™ means a wide range of observation options for comfortable viewing and fatigue-free viewing like the variable angle binocular tube. Asepsis for all controls and special objective protective glass. ISUS "Intelligent Set-Up System" which offers flexibility and user-specific configurations. |
