Leica M844 F40 belongs to the premium class of ophthalmic surgical microscopes and provides an optimal solution, particularly for advanced anterior- and posterior-segment surgery.
Combining APO OptiChrome optics and direct halogen illumination, the M844 provides crisp, bright, true-color images, even in low-light conditions.
Innovative features such as the QuadZoom technology, double-wing assistant bridge, and HD recording make it an ideal microscope for teaching institutes and university hospitals.
The Leica M844 F40 is one of the top-tier ophthalmic surgical microscopes available today. Enjoy high-resolution clarity with Leica optics, where no light is lost between the main surgeon and assistant, ensuring patient-safe low-light levels with direct illumination for optimal contrast and color. The rotating beam splitter allows for effortless switching of the assistant stereo observer between left and right, while also offering a rear-facing video port.
Key Features and Benefits
- APO OptiChrome™ Technology: Delivers true-to-life color, enhanced contrast, and razor-sharp detail across the full depth of the surgical field.
- Brilliant Red Reflex: Patented QuadZoom™ optics and dual coaxial illumination enhance the red reflex for cataract and anterior segment procedures.
- Integrated InverterScope™: Allows seamless transitions between posterior and anterior segment views without equipment reconfiguration.
- Ergonomic Floor Stand (F40): Compact and motorized with electromagnetic brakes for smooth, effortless positioning.
- Xenon Illumination: Bright, natural light ensures deep, shadow-free visibility of the cavity with high color fidelity. Halogen bulbs are built into the head for additional flexibility.
- Stereo Coaxial Illumination (SCI): Maximizes depth perception and spatial orientation during retinal surgeries. (Note: SCI is specific to the Carl Zeiss Lumera family; Leica’s equivalent is QuadZoom™.)
- Digital Imaging Options: Compatible with HD video systems for surgical recording, teaching, and consultation.
- Modular Configuration: Can be outfitted with accessories such as BIOM (Binocular Indirect Ophthalmic Microscope), assistant scopes, and 3D visualization tools.
Clinical Applications
- Retinal Surgery: High-contrast, depth-rich imaging aids delicate posterior segment procedures.
- Cataract Surgery: Enhanced red reflex and coaxial illumination support precision phacoemulsification and IOL implantation.
- Glaucoma and Corneal Surgery: Clear visualization and minimal light scattering in anterior structures.
- Teaching Hospitals and Surgical Training: Integration-ready for HD video capture, recording, and teaching overlays.
- Multi-Specialty Ophthalmic Centers: Versatile performance with scalable modularity to support various case types.
