Infusion systems
Dynamic Infusion extends traditional passive and active infusion through adaptive IOP management. Discover how it compensates for intraocular pressure changes, helping keep IOP settings near physiological levels.
3-pump system
With Peristaltic, Venturi and SPEEP, the OS 4 Up combines three pump systems in one device. The unique SPEEP pump adds independent control of flow and vacuum, providing full aspiration control in free-flow and under occlusion*.
Integrated 532 nm endolaser
The OS 4 Up features an integrated 532 nm endolaser that can be tailored to your requirements. Benefit from reliable protection with the optional laser protection filter, and enjoy added convenience with the adjustable laser aiming beam*.
Double light source
Two powerful LED light sources tailor posterior segment illumination to personal preferences and surgical situations, while Power LED Plus allows individual adjustment of colour spectrum and light intensity.
Phacoemulsification
The easyPhaco technology is developed for safe and efficient phacoemulsification. It is characterised by direct fragment followability, strong holdability and a stable anterior chamber.
Glaucoma solution
With High Frequency Deep Sclerotomy (HFDS), OS 4 Up offers an implant-free, ab interno procedure for micro-invasive glaucoma surgery (MIGS).
Intuitive pedal control
With linear, dual-linear, and easyVit modes, the multifunction pedal supports intuitive control and can be tailored to your preferred way of working. When using the integrated endolaser, the same multifunction pedal also serves as a laser pedal, providing fast availability and convenient control*.
PACS: Adaptive phaco control
Phaco Assisted Cataract Surgery (PACS) extends classic phaco modulations with adaptive control. By detecting resistance at the phaco tip and adjusting energy delivery in real time, it contributes to precise, controlled and efficient work under stable chamber conditions *.
Smooth trocar placement
The new Caliburn Trocar System is designed around the key ele- ments of smooth trocar placement. From bevelled cannula design to tactile orientation and integrated handling features, every detail works together so you can enjoy surgery.
Constant flow for efficient vitreous removal
The Continuous Flow Cutter ensures continuous aspiration thanks to its permanently open port and up to 15’000 cpm, resulting in reduced traction on the retina.
