OS 4™ MAKING THE DIFFERENCE WITH EVEN MORE VERSATILITY

Product OS4 View Frontal

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 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.

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.

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 fluidics concept, easyPhaco allows a direct fragment followability and provides a strong fragment holdability.

HFDS®
HFDS stands for High Frequency Deep Sclerotomy. In micro-invasive glaucoma surgery (MIGS), HFDS creates a direct access from anterior chamber to the Schlemm canal and further into the sclera.

The three-pump system
The innovative pump technology with vacuum and flow control is the heart of the OS 4. The three-pump system does not only offer the advantages of a Venturi or a peristaltic pump but also boasts the unique SPEEP pump.

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 perfect 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
One of the most important characteristics during eye surgery is stable intraocular pressure (IOP). To maintain a stable IOP, the OS 4 offers two possibilities of infusion systems: active and gravity.

  • MAKING THE DIFFERENCE WITH A POWERFUL PEDAL

    «Working with the OS 4 has several advantages for me, especially in the posterior segment with 27G: The infusion line is easy to click-on and does not dislocate, the flow stabilizes the eye even with higher vacuum rates and the instruments have superior stiffness. The speed of silicone oil injection/extraction is mind blowing. But what I like most is the footswitch: not only is the laser integrated, it also allows me to change the light settings with my pedal to enhance visibility and play with the contrast. My absolute favourite feature of the pedal is the luxury of being able to switch between fluid and air (and back, and back again...) with my foot.»

  • MAKING THE DIFFERENCE WITH POWERFUL FLUIDIC CONTROL AND PERFECT VISIBILITY

    «The OS 4 was my first vitreoretinal surgical platform with which I have progressed. Simultaneous control of both vacuum and flow with SPEEP provides excellent stability and minimizes intraocular pressure fluctuations. Solutions for fluidic control, safety and cutting efficiency in Oertli's platforms allow rapid, secure and continuous progress for both junior and expert vitreoretinal surgeons. The flexible chandelier gives good intraocular illumination in all surgical situations and permits precise maneuvers in bimanual surgery.»

  • MAKING THE DIFFERENCE IN EVERY SURGICAL SITUATION

    «I’m working with different Oertli surgical platforms for more than 20 years. In contrast to other platforms, it’s like working with your best friend. You can trust not only in routine cases but in every challenging and complicated surgical situation. Performance, safety, ease of use and continuous innovation are unique!»

  • MAKING THE DIFFERENCE WITH SAFETY AND SPEED

    «I started using the Oertli OS 4 for my phaco after shifting to the UAE. I find them to be a class apart in the management of both hard and soft cataracts. The chamber stability is solid and the bent I/A tip eliminated the need for any additional incisions for bimanual I/A. Personally, I am very happy with the machine and would recommend it to both beginners and experts alike while considering the safety profile and the speed at which it helps you complete the surgery.»

  • MAKING THE DIFFERENCE WITH SAFETY AND SPEED

    «Safety, control and simplicity of use define the parameters I use when it comes to choosing a medical device. Oertli OS 4 cutting edge design built on time tested traditional features gives me that confidence when operating on challenging cataracts and performing vitreoretinal surgery. This is enhanced by excellent manufacturer’s support. Thanks to its user friendly design, it is also an excellent machine for training junior surgeons.»

  • MAKING THE DIFFERENCE WITH SOPHISTICATED DESIGN

    «I have been performing vitreoretinal surgeries for decades. Oertli machines have always accompanied me reliably from the very beginning. Regular service supports the longevity of the equipment. The OS 4 combines high-tech developments with sophisticated design and enormous user-friendliness. The touch screen is clear and glare-free due to the dark background. The wide range of setting options offers every surgeon – whether beginner or experienced – the desired parameters. This makes it possible to learn and perform all surgeries with great safety.»
