The first OS 4 Up systems are set to reach South African shores in early March, following their international launch last year by Oertli Instrumente AG. We are incredibly excited to welcome this next-generation surgical platform for cataract and vitreoretinal surgery to local theatres.
Designed and manufactured in Switzerland, the OS 4 Up combines physics and fluidics to translate precision into tangible comfort in the operating room. A key innovation is Phaco Assisted Cataract Surgery (PACS), which detects resistance at the phaco tip and automatically adjusts energy delivery in real time — maintaining constant longitudinal tip movement regardless of lens density and supporting controlled, efficient performance under stable chamber conditions.
The platform also introduces dynamic infusion, compensating for IOP fluctuations and allowing surgeons to work closer to physiological pressure levels while maintaining chamber stability — even at high flow and vacuum settings.
“For us, the OS 4 Up is much more than a technological upgrade – it embodies the essence of what Oertli stands for,” says Thomas Bosshard, Co-CEO of Oertli Instrumente AG. “Surgeons and OR teams dedicate thousands of hours in the operating theatre preserving eyesight. With the OS 4 Up, complemented by our innovative instruments, we enable them to enjoy their surgery – working with confidence, efficiency and joy, while delivering the best outcomes for patients.”
We look forward to supporting South African surgeons as they begin operating with the OS 4 Up — a platform defined by precision, stability and joy in surgery.
