Key Takeaways

  • Oertli has commercially launched the OS 4 Up, a new surgical platform for cataract and vitreoretinal procedures, now available in all CE-certified markets.

  • The system features Phaco Assisted Cataract Surgery (PACS), which detects lens resistance in real time and automatically adjusts energy delivery to maintain consistent tip movement, controlled fluidics, and enhanced intraoperative stability.

  • Expanded infusion options—including dynamic infusion to compensate for IOP fluctuations—allow surgeons to maintain chamber stability at near-physiological pressure levels.

Swiss medical technology company Oertli Instrumente has announced the commercial launch of its new surgical platform, the OS 4 Up, designed for cataract and vitreoretinal surgery.

The OS 4 Up is designed to combine physics and fluidics in a platform that translates precision into tangible comfort in the operating room. According to Oertli, in developing the OS 4 Up, the company placed strong emphasis on the practical needs of users in everyday surgical settings. A key technological highlight of the device is its newly developed phaco modulation. Through Phaco Assisted Cataract Surgery (PACS), Oertli builds upon conventional phacoemulsification by integrating adaptive energy delivery.

PACS detects resistance at the phaco tip caused by dense lens material and automatically adjusts the energy supply in real time. This provides a constant longitudinal movement of the tip, regardless of lens density. By maintaining controlled energy delivery under calm chamber conditions, the technology supports precise, efficient surgical performance and enhances intraoperative stability.

The OS 4 Up also introduces expanded infusion capabilities. In addition to passive and active infusion modes, the platform now offers dynamic infusion, designed to compensate for IOP fluctuations. This allows surgeons to select IOP settings closer to physiological levels while maintaining stable intraocular conditions—even at high flow and vacuum settings. The result is enhanced chamber stability and greater confidence during complex procedures.

“For us, the OS 4 Up is much more than a technological upgrade – it embodies the essence of what Oertli stands for,” said Thomas Bosshard, Co-CEO of Oertli Instrumente AG. “The OS 4 Up runs precisely, reliably and with uncompromising performance. Above all, however, it was developed with one clear idea in mind: joy. Surgeons and surgical teams spend countless hours in the operating theatre – these should feel intuitive, safe and, wherever possible, joyful. The OS 4 Up is the result of our long-standing proximity to users and our genuine understanding of what matters in the operating theatre.”

The OS 4 Up is now commercially available in all CE-certified markets. Launches in additional countries will follow in accordance with respective regulatory requirements.
