The Leica M720 OH5 is the premium operating microscope for neurosurgery, otolaryngology and reconstructive microsurgery.

With this operating microscope, surgeons will benefit from greater visibility in deep cavities or lesions and improved ergonomics and comfort. The Leica M720 OH5 surgical microscope also offers full HD 3D and 2D visualization and recording, so that the entire surgical team as well as students will be able to observe and learn more easily.

Your Advantages

More space to work Excellent surgeon ergonomics
The Leica M720 optical head is the most compact of all neurosurgical microscopes. The compact optics head improves surgeon ergonomics by facilitating a more natural postural alignment, and allows greater instrument maneuverability by creating more free working space and unobstructed access to surgical area. Leica Microsystems' butterfly-binoculars accommodate all body heights, for both the surgeon and the assistant, as well as the most challenging surgical positions to ensure comfortable working during surgery. The eyepieces swing easily and quickly to a second viewing position.
Improved visibility in deep cavities Intraoperative fluorescence
Small Angle Illumination (SAI) distributes light more evenly, and reduces shadows in the surgical field, providing: increased detail visibility, improved depth perception, and deeper light penetration. This concentrated light beam is especially beneficial for narrow surgical access techniques such as intra-tracheal, transsphenoidal or METRx™. The surgical fluorescence modules Leica FL400 (5-ALA oncological fluorescence) and Leica FL800 (ICG vascular fluorescence) provide real-time, intraoperative information to the surgeon and OR team, directly through the microscope eyepieces or on a monitor. The information gained allows to make faster progress in work, increase surgical precision and improve patient outcomes.
Unsurpassed patient safety Full HD 3D and 2D surgical documentation
Leica Microsystems is committed to helping surgeons improve patient safety and outcomes. BrightCare Plus and AutoIris™ reduce the risk of patient skin burns by automatically optimizing light intensity and diameter relative to working distance and zoom. The Leica M720 OH5 surgical microscope integrates the TrueVision® 3D Surgical system or the Med X Change HDMD® 1080p/720p digital recording systems (optional). With the 3D visualization system, the entire team can now see on a monitor what traditionally could only be seen through the microscope eyepieces.

Improved surgeon ergonomics and instrument maneuverability

Leica M720 compact optics carrier

The substantial gain in free working distance, thanks to the compact optics carrier Leica M720, gives the surgeon unobstructed access to the surgical area and greater instrument maneuverability. Whatever the position of the patient, even sitting upright, the surgeon benefits from superior ergonomics. Improved postural alignment can lead to increased comfort and concentration, and can prevent fatigue and musculoskeletal pain during long procedures.

Smart illumination technology for unsurpassed patient safety

Example: Transsphenoidal surgery, general illustration

1. Conventional microscope illumination, WD 400 mm
2. Microscope with Small Angle Illumination, WD 400 mm

Small Angle Illumination (SAI)

SAI provides a concentrated light beam, aligned to the optical axis, thus distributing light more evenly and reducing shadows in the surgical field. The result:

  • deeper light penetration
  • increased detail visibility
  • improved depth vision

BrightCare Plus — Light intensity control

BrightCare Plus optimizes the light intensity relative to the working distance. As working distance decreases, the light intensity is reduced automatically, reducing the risk of patient burns. As working distance increases, the light intensity rises again accordingly.

1. Max. illumination: Long working distance
2. Max. illumination (BrightCare Plus inactive): Decreased working distance at same illumination setting (left) creates burn potential in conventional microscopes.
3. Microscope with BightCare Plus activated: BrightCare Plus automatically adapts light intensity to the working distance, providing safer illumination (up to 60% reduction of intensity).

AutoIris™ — Light diameter control

AutoIris™ adjusts the diaphragm so that only the visible area is illuminated. When zoomed in, the light circle adapts automatically: the higher the magnification, the smaller the light circle. This prevents the possibility of drying or burning exposed tissue, outside of the actual field of view.

1. Conventional microscope at low magnification: At low magnification, the field of illumination (yellow) fills the field of view (green) completely.
2. Conventional microscope at high magnification: Previously, as magnification increased, the field of view became smaller, but the illumination outside the field of view could potentially cause tissue burns (red).
3. Microscope with AutoIris™: AutoIris™ automatically works with the zoom, decreasing the field of illumination as the field of view decreases. There is no peripheral illumination to cause tissue burns outside the field of view.

Superior maneuverability and precise movement

Two beam focusing reference

SpeedSpot™, the fast and accurate microscope focusing feature, allows one reference point for all three viewing ports (surgeon, assistant and video camera) to be immediately in focus when positioning. The result is an optimal parafocality, sharp images and increased comfort for surgeons.

Intraoperative AutoBalance

A microscope may need rebalancing during surgery due to changing needs for the surgeon's and assistant's positioning. With one push of the AC/BC button, located above the optical head, the surgeon can rebalance in seconds, even through the sterile drape.

Highest overhead clearance and longest reach

The Leica M720 OH5's long arm gives it the highest overhead clearance and longest reach of any surgical microscopes on the market today. This, combined with a compact footprint, enables surgeons to position the microscope out of the way, to obtain the perfect vantage point and continue working comfortably.
