Oertli Faros Surgical Platform

The unique pump innovation from Oertli. The SPEEP pump uses the same principle as a peristaltic pump to control the flow. With SPEEP the vacuum can also be controlled using the foot pedal. This enables precise control of the holding force generated right at the instrument opening.

How does the SPEEP pump work?

SPEEP combines the advantages of a flow-controlled peristaltic pump with the responsiveness of a vacuum-controlled venturi pump.

The SPEEP pump allows both the flow and vacuum to be controlled independently of each other. The foot pedal not only allows aspiration and release but also gives the surgeon complete control when holding and manipulating fragments and tissue. SPEEP continues to control the vacuum even under occlusion.

What are the benefits of the SPEEP pump?

With challenging cases such as floppy iris syndrome or zonular weakness, precise control of the fluidics is essential. Thanks to the independent settings for flow and vacuum, SPEEP generates dosable holdability at the instrument opening — giving surgeons complete control.

Thanks to the use of the fluidics technology and the precise flow control, easyPhaco enables immediate aspiration of the lens material for perfect followability. The unique design of the tips ensures unmatched chamber stability while simultaneously providing very high holdability. The fragments are aspirated efficiently and without repulsion. The focused axial delivery of the ultrasound energy guarantees targeted emulsification directly into the lens fragment. And, because the Oertli easyPhaco handpiece is equipped with six Piezo crystals, the transmission of power to the tip happens in a direct and gentle way with less heat development.

For surgical treatment of glaucoma, the OS 4 generates appreciable added value in microinvasive glaucoma surgery (MIGS). High-Frequency Deep Sclerotomy (HFDS) has a low rate of complications and delivers promising long-term results even with a shorter procedure. HFDS provides direct access from the anterior chamber to the Schlemm’s canal and further into the sclera. The outflow resistance of the trabecular meshwork is thus significantly reduced. The HFDS glaucoma tip is inserted through a 1.2 mm paracentesis and uses high-frequency diathermy delivery to place six small sclerotomy pockets in the iridocorneal angle, which provide an improved outflow of the aqueous humour.

The dual-linear foot pedal is the versatile control unit of the Faros. Manufactured from robust metal and precisely finished, the pedal responds to the surgeon’s commands without delay.

Dual-linear versatility

The pedal lends the surgeon control and can be customised to the surgeon’s wishes and needs. Many different functions, for example shifting of functions (change of pump, light, air) and adjustment of the bottle height, etc. can be allocated to the auxiliary buttons.

Making best possible use of fluidics and physics has always been a distinct feature of Oertli that resulted in its establishment as an innovative leader in this sector of ophthalmology. The impressive fluidics system is no doubt one of the key elements for the exceptional performance of this platform.

The Faros excels with its ease of use to make operation comfortable and safe for both the OR staff and the surgeon. The surgical platform is also exceptionally quick to start up: the system is ready to use within seven seconds after being switched on.

In retinal surgery, irrigation can be deactivated for a defined period (Irrigation Off), such as when the surgeon would like to lower the IOP to examine the peripheral retina.

Most instrument connections are easily accessible from the front to make preparation for surgery both simple and efficient.

The light and clearly readable displays of the control field give precise information on operating values and settings. The logically arranged control buttons are always allocated the same functions that can be activated instantaneously by button pressure. The various functions are individually set for each surgeon and surgical technique in the ParaProg background menu. Programming is possible for up to 50 surgeons.

Thanks to the Power LED light source, the light output is up to 45 per cent greater than the previous generations. The Faros has a light source that provides homogeneous illumination and high durability thanks to its latest Power LED technology. The wide control range is an ideal combination with 3D microscopes, especially in case of low lumens.

Developed for a stable IOP

An important criterion during eye surgery is a stable intraocular pressure (IOP). To maintain this IOP, the Faros offers two options of infusion systems: the active as well as the gravity infusion.

Active infusion

The gas-driven active infusion is available on the OS 4 and Faros devices. In the posterior segment version, the Faros offers active infusion in cataract surgery. In the case of bleeding or other situations requiring high pressure, the active infusion can react quickly and reach a pressure of up to 120 mmHg. The active infusion is independent of the room height as the BSS bottle is suspended from a fixed hook. It is connected to the compressed air outlet (GFI = Gas Forced Infusion) via a Luer lock connection, whereby the connection is colour-coded to avoid installation errors.

Gravity infusion

The gravity infusion is mechanical driven and available on all three Oertli platforms: OS 4, Faros and CataRhex 3. Like the active infusion, the gravity infusion is also designed for stable IOP during surgery. Pressure can go up to 100 mmHg or 135 cm, and both setting values are selectable. As the tubing set is part of most phaco and vitrectomy single-use packs from Oertli, the gravity infusion is an economical solution.
