Smart and Sophisticated

SCHWIND SmartSquare – the combination of SCHWIND ATOS femtosecond laser (on the left) and SCHWIND AMARIS excimer laser (on the right).

SCHWIND has a track record of continually developing and improving its excimer laser platforms – and this trend continues with the company’s recent offering: ATOS. An intelligent femtosecond laser with a sophisticated eyetracking system, ATOS pushes the boundaries of lenticule extraction, making the procedure available to more patients.

ATOS can be used to perform SmartSight – an up-to-date femtosecond laser procedure (without a flap) that allows refractive correction for myopia and astigmatism. And because the procedure can be performed in its entirety with ATOS, surgeons benefit from well-considered workflow benefits at every phase.

In particular, refractive surgeons will welcome the sophisticated eye tracking system; the pupil recognition and integrated static cyclotorsion compensation at play allow easy and precise centration of the patient’s eye along the visual axis. The innovative design includes an optimized patient interface geometry with improved suction and an integral filter function (which eliminates the need for additional tubes and filters). It is ready for use in just to steps. The suction time and incision procedure are kept as short as possible.

The innovations at the heart of ATOS are a logical consequence of SCHWIND’s comprehensive expertise in technologies for smooth corneal surfaces. From a technical point of view, its pulse rate of up to 4 Mhz, sophisticated pulse characteristics, and refined positioning algorithms all add up to short treatment and incision times. And the improved lenticular geometry is not limited by a minimum thickness, which helps save tissue.

But the innovations don’t stop at serving the surgeon. The curved interface, which follows the corneal limbus, not only provides a good fit, but also reduces pressure on the eye during positioning, increasing patient comfort. And because the patient can remain in a single position for all treatment steps, comfort is further improved – especially when combined with the speed of the procedure.

The compact device has a small footprint; the monitor and keyboard are mounted on a swiveling arm that not only lets the user adjust the position to suit their needs, but can also be folded back against the body of the machine for easier repositioning in the clinic. The laser is controlled via clear and intuitive software displayed on two high-resolution (24- and 10-inch) touch screens (PCT).

In addition to SmartSight, ATOS allows flap cutting for FemtoLASIK. In fact, ATOS was designed to cover all advanced laser procedures in refractive corneal surgery, including SCHWIND SmartSquare, which combines AMARIS excimer laser and ATOS femtosecond technology.

Whether lenticules or flaps, ATOS provides a homogenous surface, making SmartSight lenticule extraction simple and allowing the flap to be easily lifted in FemtoLASIK. Notably, ATOS can be used to create flaps of various diameters, which is particularly helpful in excimer laser treatment of hyperopia and mixed astigmatism.

SCHWIND is committed to giving surgeons the best possible tools to work with. And that is why the company continues to work on improvements, additional applications, and a larger product portfolio to support surgeons with appropriate solutions for human cornea treatment. The aim is simple: to further improve the surgical experience and – ultimately – improve patients’ vision and quality of life.

ATOS was presented at ESCRS 2019 in Paris, France, and received its CE mark in July 2020. It is now available in Europe, and other regions will follow, starting with Asian markets.
