The efficient compact model
The SCHWIND AMARIS 500E combines efficiency and safety. Automatic Fluence Level Adjustment (AFLA) ensures an optimal balance between the total number of laser pulses and the energy delivered. The result is fast ablation with advanced smoothening of the cornea.
The laser system, with a 500 Hz repetition rate, is well complemented by a 5D eye tracker, which compensates for eye movements in five dimensions. The SCHWIND AMARIS 500E is trusted by eye surgeons, and the outstanding performance of this compact laser system is verified by numerous studies.4 – 6

Precise: 5D eye tracking
Treatment success is enhanced by SCHWIND’s proprietary active 5D 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
Changes in pupil size are detected, and the laser is adjusted as necessary. In conjunction with the 5D eye tracker, this automatic function ensures correct centring throughout the procedure.
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.

Versatile: SCHWIND CAM
The modular SCHWIND CAM software facilitates optimum treatment planning for a very wide range of applications in refractive and therapeutic corneal surgery. SCHWIND CAM takes into account all diagnostic data, including corneal wavefront, ocular wavefront and pachymetry (central cornea thickness).
The modules are:
• ORK-CAM for refractive corneal surgery
• PresbyMAX for presbyopia treatment
• PTK-CAM for therapeutic corneal surgery
The KPL (keratoplasty) option in PTK-CAM supports safe and precise corneal transplants for patients for whom perforating keratoplasty is indicated.

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.
