The OS 4 surgical platform utilises the laws of physics with the aim of making ophthalmic surgery even safer, easier and more efficient. The heart of the platform is the 3-pump system with vacuum and flow control and the innovative SPEEP pump, which can control flow and vacuum simultaneously. The Power LED technology with its double light source provides homogeneous illumination and high-resolution contrast viewing. The pneumatically driven Continous Flow Cutter supports low-traction work in the periphery and the fully integrated 532 nm endo laser provides reliable eye protection during treatment. Make the difference – by using Oertli's OS 4.
