Schwind Amaris 750 S

Minimum treatment time

The SCHWIND AMARIS 750S works two to three times
faster than other laser systems. 750 tiny light flashes
per second shape the corneal surface. It is extremely
fast and corrects one dioptre of myopia within
1.5 seconds, and eight dioptres are ablated within
13 seconds.

Automatic Fluence Level Adjustment

In order to perfectly combine speed and precision, the
SCHWIND AMARIS 750S is equipped – besides a 750 Hz
pulse frequency – with two energy levels. At first, the
SCHWIND AMARIS 750S uses a high energy level and
rapidly ablates around 80 percent of the tissue to be
removed – like a fast yacht quickly heading for the safe
harbour. How long the powerful beams are applied
depends on your individual refractive error and is continuously
checked by the software during the treatment.
Like a small sport boat then exactly navigates to a
narrow landing, a gentler beam ablates the remaining
20 percent, thus assuring an especially smooth surface
and perfect vision.

Eye tracking in six dimensions

The eyes can involuntarily move in all directions for
milliseconds while fixating on the laser light. The
SCHWIND AMARIS 750S eye tracker monitors the position
of the eye with approximately 1050 measurements per
second and thereby compensates any deviation up to
the sixth dimension.

Imagine your eyeball being a buoy in the sea: When the sea
is calm, the buoy shifts from the left to the right or forward
and backward. In swell, however, the buoy tilts to the side.
Furthermore, a buoy also turns around its anchorage
or moves upward and downward. In the same manner,
your eyeball can roll (rotation), rotate around its own
axis (cyclotorsion) or move up and down along the z-axis.
The eye tracker of the SCHWIND AMARIS 750S detects
all these eye movements and compensates them. With
cyclotorsion control, the compensation occurs statically,
between the sitting and lying positions of the patient,
and dynamically during the laser treatment.

Permanent measurement of corneal thickness

Similar to a diver orientating himself in water with his
depth gauge, your doctor is permanently informed through
the online pachymetry of the SCHWIND AMARIS 750S.
This system measures the changes of corneal thickness
in real time and displays them on the treatment screen.
Thus, your doctor knows at every point in time how
much tissue he has already ablated and how thick the
remaining cornea still is.

Exceptionally fine laser beam

The laser beams of the SCHWIND AMARIS 750S have
an exceptionally small diameter of only 0.54 millimetres
and are thus significantly smaller than others. Further-more they have a special shape. Your cornea becomes
especially smooth with this fine beam.

Constant microclimate

With the SCHWIND AMARIS 750S, two specially formed
nozzles ensure a directed, fine airflow that creates a
stable microclimate across the cornea. The climatic
conditions remain constant, preventing the cornea from
drying out.

Unique thermal control

The SCHWIND AMARIS 750S is equipped with a unique
thermal control system. Even at high ablation speed the
corneal tissue is effectively preserved. The laser pulses
are temporally and spatially sorted, which gives the
individual position on the cornea sufficient time to cool
off. Following pulses can thereby approach an already
cooled position faster.

Clinical results

A multitude of international clinical studies have documented
the excellent treatment quality with SCHWIND
AMARIS technology. Visual acuity of 100 percent or better
was achieved in nearly all cases.

A high percentage of treated patients could see better than
before with glasses or contact lenses.
The study results also show improved contrast vision.
