HFDS or High Frequency Deep Sclerotomy is a particularly simple and fast method in micro-invasive glaucoma surgery; it relies on bipolar high-frequency diathermy. Here, direct access from the anterior chamber to the Schlemm’s canal is created, which results in a drastically reduced outflow resistance of the trabecular network. The HFDS method offers an effective and sustained decrease in pressure and a very low complication rate. HFDS is available on CataRhex 3, Faros and OS 4.


The Oertli surgical platform CataRhex 3 impressively demonstrates that great platforms can sometimes be very small. With hitherto unachieved compactness and a light weight of five kilogrammes, the CataRhex 3 device is consistently geared to mobility and portability – without making any compromises on performance. easyPhaco technology ensures safe and efficient emulsification. Thanks to the HF capsulotomy tip, capsulorhexis has become incredibly easy. In the I/A mode, CortexMode ensures even greater safety. A compressor has been integrated for anterior vitrectomy, and in glaucoma surgery, the HFDS application ensures excellent long-term results. Make the difference – with the CataRhex 3 by Oertli.


The Faros surgical platform enables eye surgery of the highest level while constantly remaining comfortable and intuitively operable. Constructed on a modular basis, Faros is available as a pure phaco device, but can be extended to become a combined system for the anterior and posterior segment. The precise flow control makes the surgeon’s work even simpler and safer than before. The easyPhaco technology brings about unsurpassed chamber stability. The HF capsulotomy allows for an incredibly simple capsulorhexis. In addition, Faros has an integrated HFDS application for glaucoma surgery, the innovative continuous flow cutter for traction-free vitreous body removal and up-to-date LED technology. Make the difference – with Faros by Oertli.

OS 4™

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 three-pump system with vacuum and flow control and the innovative SPEEPMode that ensures highly precise manoeuvres. All instruments are perfectly integrated into the system: cutting-edge LED technology provides for optimum visualisation, 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. Making the difference – with the OS 4 by Oertli.



The surgical platforms by Oertli create a closed surgical system together with their matching instruments. Every instrument is compatible with every Oertli surgical device provided the relevant function is available. Of course, Oertli consistently relies on quality in the production of its instruments, hand pieces, tips and auxiliary agents. Instruments are developed in Berneck and perfected with highest precision – so that surgeons can fully rely on their tools.
