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 ensures 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 primarily useful 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
VISULAS Trion offers flexible and highly selective treatment options for a wide range of retinal diseases offering:
532nm green wavelength - the gold standard for pan-retinal photocoagulation
561nm yellow wavelength add more suitable for the central retinal region and cloudy media, and
659nm wavelength for better subretinal penetration, with rapid switching capabilities between the three laser wavelengths.
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.
Laser red
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.

Enhanced workflow
The illuminated SPOTview™ display allows the physician to continuously monitor the laser spot diameter, even in darkened environments.

Compact in design
Due to the mobile design the laser module can be moved between treatments rooms or into the operating room with ease.

Solid performance in the operating room
A perfect duo together with the OPMI LUMERA® 700 surgical microscope.

Two illuminated and color-coded fiber ports
Provide wavelength confirmation and facilitate quick transition to laser indirect ophthalmoscope.
