OS 4™ MAKING THE DIFFERENCE WITH MORE VERSATILITY

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, capable of controlling flow and vacuum at the same time. 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.
Latest Power LED technology with double light source provides optimised visualisation and high-resolution contrast viewing. The Continuous Flow Cutter ensures traction-free vitreous removal. Last but not least, the fully integrated 532 nm endo laser with an automated laser user protection filter opens up unprecedented possibilities in laser control.
Make the difference – by using Oertli's OS 4.
The platform for all cases
The OS 4 by Oertli is the powerfully efficient all-in-one platform for cataract (phaco), glaucoma and vitreoretinal surgery. As a versatile and user-specific OR device, the OS 4 works as the extended hand of the surgeon and carries out his orders and intuitions perfectly.
Features of the OS 4
SPEEP® pump
The SPEEP pump uses the same principle as a peristaltic pump1 to control the flow. SPEEP also allows the vacuum to be controlled with the foot pedal.
easyPhaco® technology
Fluidics based on physics. Thanks to Oertli’s unique fluidics concept, easyPhaco allows direct control over fragments and ensures a high holdability.
HFDS®
HFDS stands for High Frequency Deep Sclerotomy. In microinvasive glaucoma surgery (MIGS), HFDS provides direct access from the anterior chamber to the Schlemm’s canal and further into the sclera.
The top-class pedal
The wireless and dual linear foot pedal is the multifunctional control centre of the OS 4. Manufactured from robust metal, the pedal responds precisely and without delay to the surgeon’s commands.
The 3-pump system
The heart of the platform is the 3-pump system with vacuum and flow control and the innovative SPEEP pump, capable of controlling flow and vacuum at the same time.
Simple and safe operation
The OS 4 is designed for absolute user-friendliness. The 15-inch touchscreen with the graphic user interface is simple and intuitive to operate. After a switch-on time of less than 30 seconds, the OS 4 is ready for operation and the acoustic voice signals further support the operation.
Power LED technology
Thanks to the new Power LED, the light output in the OS 4 has been increased by an additional 45 percent2 - for homogeneous illumination and visualisation during all manoeuvres, extending to the periphery.
Perfect laser integration
The OS 4 offers a fully integrated 532 nm endo laser of Swiss production. The laser is ready for operation within the shortest time possible and can be controlled directly by means of the dual-linear pedal.
Infusion system
An important criterion during eye surgery is a stable intraocular pressure (IOP). To maintain this IOP, the OS 4 offers two options of infusion systems: the active as well as the gravity infusion.
