    Simplify visibility

    to save valuable time during surgical procedures

    Experience breakthrough visualization capabilities combined with an optimized workflow when using ZEISS EXTARO 300 for general otolaryngologic procedures, such as tympanoplasty, myringotomy, stapedectomy, mastoidectomy, and transoral laser surgery.

    The intuitive functionalities minimize interruptions and maximize your focus on surgery. Innovative data management solutions enable you to capture photos and record videos of every treatment, organized according to your needs. Due to its small footprint, easy maneuverability, and adjustable axis, it can be positioned flexibly in the operating room – even when space is limited.

Augmented Visualization MultiSpectral Mode

Augmented Visualization

with integrated capabilities for a clear view

ZEISS EXTARO 300 enables a more accurate assessment of the surgical situation for better decision making. The MultiSpectral Mode, NoGlare Mode, and a powerful illumination enhance surgical visualization, allowing you to make the right surgical decisions even in deep anatomical structures – for a better outcome for your patients.

Visualization enhanced – ZEISS EXTARO 300

    MultiSpectral Mode

    for enhanced contrast

    Low-color contrast often makes it difficult to recognize critical anatomical structures. The MultiSpectral Mode of ZEISS EXTARO 300 enhances this contrast, for example to better distinguish between vasculature and tissue or to check the viability and thinness of the tympanic membrane.

  • Microscope application no glare

    NoGlare Mode

    to suppress disturbing reflections

    Sometimes light reflections complicate the surgical procedure and fine structures are barely recognizable. The NoGlare Mode of ZEISS EXTARO 300 suppresses these obtrusive reflections from liquids like blood or water, allowing for faster and more detailed distinction of anatomical details and artificial implants.

Single-Handed Operation

Single-Handed Operation

with easy-to-use interactions

Since every intervention is unique, maximum concentration during a procedure is required to react to deviations adequately and quickly in the surgical workflow. Even the slightest adjustment or repositioning of the ENT microscope can greatly disturb focus and cost valuable time. Thanks to the user-friendly Mode Control button and Varioskop 230 of ZEISS EXTARO 300, which can be adjusted effortlessly with just one hand, you can perform procedures with maximum focus and efficiency. Best in class.

Usability perfected – ZEISS EXTARO 300

Mode Control

to minimize disruption to the surgical workflow

With the Mode Control button, ZEISS EXTARO 300 allows you to activate all visualization modes and camera functionalities without taking your eyes off the surgical field. With its innovative balancing and movement system, frequent repositioning will no longer be a burden on your procedures.

Varioskop 230

to focus on the essentials

The Varioskop 230 allows you to effortlessly set the field of view and focus over a wide working range of 200 to 430 mm without moving the microscope – using just one finger for ergonomic handling.

Laser compatibility

for easy mounting

ZEISS EXTARO 300 is fully compatible with the micromanipulators of manufacturers and offers a tried-and-tested mounting system. With the optional laser package, the focus of the microscope can be locked on the same focal plane as the surgical laser to perform delicate procedures on the larynx and inner ear.

Digital Data Management

with smart solutions

High patient throughput and the associated documentation can be tedious when collecting, organizing, and storing procedure-related images and videos. ZEISS digital solutions offer an easy and efficient pathway to data management and facilitate professional peer collaboration and education. Integrate apps such as ZEISS Surgical Cloud and ZEISS Livestream in your daily routine to effectively store, share, and stream your clinical cases directly from your device.
