The powerful performance laser
The SCHWIND AMARIS 750S offers high performance, proven outcomes and safety. The laser system ablates the cornea at two difference fluence values, thereby achieving a good combination of speed and precision. A very fine laser spot, with a diameter of just 0.54 millimeters (FWHM) ensures smooth corneal modelling.
With a repetition rate of 750 Hz, the SCHWIND AMARIS 750S achieves very short treatment times. The 6D eye tracker takes 1050 measurements per second to monitor the exact position of the eye in six dimensions. It actively compensates for any deviation with an ablation time of up to 1.5 seconds per dioptre.1

Precise: 6D eye tracking
Treatment success is enhanced by SCHWIND’s proprietary active 6D eye tracker which enables a unique level of precision. It is linked to the SCHWIND diagnostic systems and captures all eye motion (static as well as dynamic) during the procedure, for outstanding outcomes.
During the procedure, it precisely determines and compensates for the following eye movement dimensions:
- X-axis
- Y-axis
- Horizontal rolling
- Vertical rolling
- Eye rotation around the visual axis: static and dynamic cyclotorsion
- Z-axis: active compensation for upward and downward movements
Changes in pupil size are detected, and the laser is adjusted as necessary. In conjunction with the 6D eye tracker, this automatic function ensures correct centring throughout the procedure.
Patient expectations are constantly increasing with regard to treatment methods and the results attainable in corneal surgery. If you can offer the shortest treatment times with perfect results, you have the upper hand. This is where the SCHWIND AMARIS family of laser systems sets a new standard, delivering greater safety and patient comfort.
Innovative and reliable
The SCHWIND AMARIS 1050RS is a major milestone in refractive corneal surgery, achieving a repetition rate of 1050 Hz, currently is one of the highest of any excimer laser in the market. This innovative excimer laser decreases the extremely short ablation time of the product family even further, to 1.3 seconds per dioptre2 – the ablation times achieved with the AMARIS 750S and AMARIS 500E are no less impressive. In practical terms this means shorter treatment times and minimised risk of corneal dehydration. Moreover, the length of time the patient has to fixate on the green light is significantly shorter.

Plan individually for each situation
Comprehensive treatment planning with complete diagnostic data
Each treatment is different. That is why the entire AMARIS product family, with the modular SCHWIND CAM software, makes it possible for you to plan treatment individually for your patients across an exceptionally wide range of applications in corneal surgery. Whether corneal or ocular wavefront, pachymetry or epithelial data – all the required diagnostic information are incorporated into planning.
You can be sure that you will not leave out any detail important for the individual ablation.
SCHWIND CAM modules and the advantages for you
ORK-CAM
A one-of-a-kind intelligent planning tool for wide-ranging and tailor-made refractive laser treatment. Aspheric ablation profiles are employed for both aberration-free and customised treatments based on (total) corneal or ocular wavefront data.
PresbyMAX
This module is ideal for safe and efficient treatment of patients with emmetropia, myopia, hyperopia and astigmatism, whose accommodative response is limited. PresbyMAX is based on bi-aspheric ablation profiles.
PTK-CAM
This module supports you in performing therapeutic treatments. Superficial as well as deep corneal scars and corneal degenerations can be exactly localized and treated with a procedure in which the corneal tissue is ablated in either a circular, elliptical or an individualised shape. You can choose between a more superficial refraction-neutral or a deep ablation for performing laser keratoplasty.
Touch-free treatment with SmartSurfACE
SmartSurfACE combines the benefits of touch-free TransPRK surface treatment with innovative SmartPulse Technology.8, 9
It works without touching the eye. There is no suction, no blade and no incision – vision is corrected through the top layers of the cornea with SCHWIND AMARIS technology, gently, touch-free, in a single step. The treatment with SmartSurfACE on regular corneas speeds up the healing process and yields good vision quality even in high myopic eyes.
The advantages over other surface treatment methods are obvious – the epithelium is removed more precisely, more uniformly and more easily than with manual or alcohol-assisted debridement.
SmartSurfACE is suitable for any laser candidate as well as patients with thin corneas, corneal pathologies or complex topographies.

Automatic Fluence Level Adjustment
Ideal balance between the total number of laser pulses and energy delivered
AFLA - An ideal balance
With the Automatic Fluence Level Adjustment (AFLA), the SCHWIND AMARIS product family achieves desired level of corneal smoothening even at the highest ablation speed.* Researchers at SCHWIND have developed an algorithm that ensures an ideally balanced ratio between the total number of laser pulses and the energy delivered.
About 80 percent of the ablation is performed with a high fluence value. For the fine modelling – the remaining 20 percent – AFLA automatically switches to a lower fluence. The result is optimum smoothing of the cornea. Through the extremely small beam size and Super-Gaussian beam profile, you achieve desired ablation smoothness.
ITEC - Gentle even at the highest speeds
Intelligent Thermal Effect Control (ITEC) is the name of the thermal control process that prevents damage to the surrounding corneal tissue, even at the very high ablation speeds of the SCHWIND AMARIS product family. ITEC ensures that the laser pulses are distributed in a thermally optimised, dynamically adapted way, which gives the individual position on the cornea sufficient time to cool off. The following pulses can therefore approach an already cooled position faster. ITEC is better than the static processes. Studies using an infrared thermographic camera have proven that the corneal tissue only heats up minimally, even at high ablation speeds.*
The thermal control technology and ablation control with two fluence levels play a very important role, especially in biological terms: the less the biological interaction with the corneal tissue, the more reliably wounds can heal.
