OS 4™ MAKING THE DIFFERENCE WITH EVEN MORE VERSATILITY

The OS 4 is not cleared by the FDA for distribution in the United States. For more information on our FDA-approved surgical platform for the U.S. market, please click here.

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.

The platform for all cases

The OS 4 is the all-in-one-platform for cataract, glaucoma and retinal surgery. Everything about the OS 4 is clear and easy. This makes operation comfortable and easy to understand for both OR personnel and the surgeon.

SPEEP® pump
The SPEEP pump uses the same principle as a peristaltic pump * to control the flow. SPEEP also allows the vacuum to be controlled with the foot pedal.

* Modulation according to the principle of the peristaltic pump

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.

Comfortably fast - intuitively clever
Everything about the OS 4 is clear and easy. This
makes operation comfortable and easy to understand for both OR personnel and the surgeon. The operating platform is ready for start extremely quickly thanks to its own software technology. Following a switch-on time of about 30 seconds,
the system is ready for start. This makes changeover between surgeries very short.

Perfect laser integration
The fully automated laser user protection filter enables a reliable eye protection during treatment. The fully automatic insertion of the filter glass before the laser treatment saves the OR team precious time and energy.

Infusion system
An important criterion for eye surgery is maintenance of the intraocular pressure (IOP) to ensure a stable anterior chamber and a stable eye. To maintain the IOP, the OS 4 has two options for infusion systems: active infusion and gravity infusion *.

    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 D

    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 D

    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! D»

    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 D

    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 D

    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 D
