    Four different wavelenghts for frequently varying laser applications

    The VISULAS® Trion Combi from Carl Zeiss combines the multi-wavelength laser VISULAS Trion for posterior photocoagulation with the VISULAS YAG III for anterior photodisruption. This multi-purpose laser provides four different wavelengths for the three most common therapeutic laser applications in a single compact workplace for the first time. The VISULAS Trion Combi is excellently suited for performing iridotomies with pre-coagulation: a single touch of the control panel switches the interface from the photocoagulation to the photodisruption mode.

    Legendary ZEISS optics

    For decades Carl Zeiss Meditec has been developing high-quality therapeutic lasers featuring outstanding precision and legendary optics from ZEISS. Perfectly integrated laser slit lamps guarantee superior slit lamp image quality, which is an important requirement for reproducible clinical results.

    Both lasers also perform effectively as individual units. The VISULAS Trion can be used in the operating room while the VISULAS YAG III can continue to be used with the combi slit lamp.

    Only as much energy as necessary

    The VISULAS Trion Combi focuses the optimum amount of YAG laser energy directly to the target thanks to its Super-Gaussian beam profile. It therefore requires less energy to achieve the optical breakdown, as little as 2.5 mJ in air. The result: high-precision treatment to the patient using a minimum of laser energy.

    Variable focus shift

    The focal point of the aiming beam is set precisely and reproducibly before, behind or directly at the focal point of the disruption laser.

    docor and treatment

    Gentle laser treatment

    The ParFocus™ zoom system of the VISULAS Trion delivers a homogeneous, sharply defined and reproducible laser spot on the retina and minimizes heat-related side-effects on the patient's cornea.

    Enhanced workflow

    All controls for both lasers are available on one central control panel with a detachable display. The coagulation laser is operated quickly and accurately using the electronic micromanipulator integrated into the joystick. The trigger for the YAG laser is incorporated in the slit lamp joystick.

  • Options & Accessories
