OS 4™ MAKING THE DIFFERENCE WITH MORE VERSATILITY

The OS 4 surgical platform uses the laws of physics and fluidics to make eye surgery safer, easier and more efficient than it has ever been.
The core piece of the device is the 3-pump system with vacuum and flow control and the innovative SPEEP pump that ensures highly precise manoeuvres. The HFDS (High Frequency Deep Sclerotomy) technology is used in microinvasive glaucoma surgery (MIGS) to provide direct access from the anterior chamber to the Schlemm's canal and further into the sclera.
The cutting-edge Power LED technology with even more light power ensures optimised visualisation and high-resolution contrast vision. The continuous flow cutter ensures traction-free vitreous body removal, and the fully integrated 532 nm endo laser opens up new possibilities in laser control.
Make the difference – with the OS 4 by Oertli.
