Great surgery starts with the right feeling.

We are happy to announce the commercial launch of our new surgical platform, OS 4 Up, for cataract and vitreoretinal surgery. Development, design and production are carried out entirely at the our headquarters in Berneck with more than 75 years of innovation along with consistent Swiss development and manufacturing expertise. With the OS 4 Up, we combine physics and fluidics, transforming precision into tangible comfort enabling surgeons and OR teams to focus on what matters every day: enjoying surgery.

The OS 4 Up is now available in all CE-certified markets. Other countries will follow with their respective regulatory requirements *.

Focus on operational excellence in the operating theatre

Surgeons spend thousands of hours in the operating theatre throughout their careers and rely on high-quality, dependable medical technology. Accordingly, the development of the OS 4 Up focused on users’ requirements and needs in their everyday surgical practice. As a powerful platform, the OS 4 Up supports consistently efficient operating theatre workflows and can be individually tailored to the surgeon's personal working style.

Adaptive phaco modulation

One of the technological highlights of the OS 4 Up is the newly developed phaco modulation. With Phaco Assisted Cataract Surgery (PACS), we expand on classic phacoemulsification by incorporating adaptive energy delivery. PACS detects resistance at the phaco tip caused by dense lens material and adjusts the energy supply in real time. This maintains a constant longitudinal movement of the tip, regardless of lens density. This enables surgeons to work precisely in a controlled and efficient manner, under calm chamber conditions *.

Reduce IOP settings and remain stable

The OS 4 Up offers three types of infusion: in addition to passive and active infusion, dynamic infusion is now available to compensates for intraocular pressure fluctuations. This allows surgeons to select IOP settings close to physiological levels, while intraocular conditions remain stable even at high flow and vacuum settings *.
