Phacoemulsification – powerful and controlled.
Beyond what you imagined possible. Maximum suction, continuous flow – top-class performance for soft and hard cataracts.

Demanding cataracts, fragmented faster
The higher frequency creates a stronger jackhammer effect: the nucleus fragments faster — with controlled energy input. The endothelium remains protected in the bench results.² You can choose:

From the OR
Listen to those who have already tested it.⁵
What impressed me most was the anterior chamber stability. It is virtually impossible to destabilize the device and its pressure control. That is a truly outstanding characteristic of VIVOS.
Prof. Dr. med. Lars-Olof Hattenbach
Director, Eye Clinic at Klinikum Ludwigshafen
The anterior chamber remained stable even at 700 mmHg, which is very important. In terms of fluidics and pressure stability, the system was highly predictable and easy to work with.
PD Dr. med. Hyeck-Soo Son
Senior Consultant & Head of Refractive Surgery, University Eye Clinic Heidelberg¹
What excites me is that VIVOS applies modular technology for different surgical settings – combined with excellent anterior chamber stability and a compact, well-handling machine.

The VIVOS ECOSYSTEM
The VIVOS Ecosystem combines high-quality GEUDER components into one cohesive solution for eye surgery – precise, reliable, and consistently aligned with the surgical workflow.
Phaco
Choose between the 42 kHz or the new, lighter 53 kHz ultrasound handpiece for even more efficient removal of the hardest cataracts with reduced heat generation. Also in the portfolio: highly efficient phaco tips as well as irrigation/aspiration handpieces – reusable or sterile.
Tamponades
With integrated compressor technology, VIVOS supports air and oil injection directly from the system. An external compressed air supply is not required – for more flexibility in the OR, less dependence on infrastructure, and easier integration into existing workflows.
Vitrectomy
VIVOS device systems are compatible with UNO Colorline vitrectors, light guides, and trocars. The open port of the vitrectors, combined with matching trocars, maintains continuous aspiration — with maximum duty cycle and stable flow. For clean and efficient vitrectomy at up to 24,000 cpm.
Laser & Light
Precise endocoagulation and endoillumination with matching laser probes and light guides – finely tuned for the posterior segment and fully integrated with VIVOS NOVA+.
Cassette
Other systems require regular cassette changes. VIVOS offers a choice: a multi-patient cassette for the entire OR day, reducing changeover effort and saving time, or a single-use cassette for individual procedures.
