    VISULAS Trion

    Intelligent multi-wavelength laser for highly selective treatment choices

    The VISULAS® Trion is a high-performance, compact, diode-pumped solid-state laser. Its active thermoelectric cooling guarantees reproducible laser performance. The VISULAS Trion is designed for photocoagulation of the retina, trabeculoplasty and iridotomy for treatment of glaucoma. The VISULAS Trion with the VITE option is mainly used for multi-spot panretinal and grid photocoagulation.

    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.

    Control stick

    Sensitive laser positioning

    The electronic micromanipulator allows navigation with fingertip precision for sensitive, synchronous laser beam positioning and slit lamp illumination.

    doctor and patient tratment

    Gentle laser treatment

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

    Significantly reduced treatment times

    Equipped with the VITE option, the VISULAS Trion is capable of delivering multi-spot treatment cascades both as automated as well as controlled sequences without compromising the outcomes of the gold standard. Up to 12 laser pulses per cascade can be triggered with a single press of the button on the slit lamp joystick.
