LASEK

AMARIS RED LASEK / Today LASEK

AMARIS 1050 RED

Every ablation and every correction is completed using only a single beam of laser light. All-laser LASEK does not use a blade, from removal of the corneal epithelium through vision correction. It is a non-contact vision correction procedure performed using 100% laser only. Germany's SCHWIND Amaris Red system emits ultra-high-speed pulses and features a 7D Eye Tracker: seven-dimensional eye-tracking system technology. This minimizes thermal damage to the cornea and creates a smoother ablation surface. As a result, it provides shorter procedure times, less pain, and clearer visual quality.

❶ Ultra-high speed of 1050 Hz

The fastest excimer laser speed currently available and stability, both at once

AMARIS RED uses an ultra-high-speed 1050 Hz pulsed laser, requiring only 1.3 seconds to correct 1 diopter. At more than 50% faster than conventional systems, it preserves more residual corneal tissue while minimizing heat damage to the eye.

❷ 0.54 mm ultra-fine ablation

More precise than cells, smoother than ever

The smaller the laser beam, the more precise the procedure can be. A precise 0.54 mm laser beam, 3.5 times thinner than conventional lasers enables rapid, smooth polishing of the corneal surface for high-quality visual recovery.

❸ Seven-dimensional eye-tracking system

Technology that accounts for every movement of the eye

A seven-dimensional ultra-precise eye-tracking device tracks the eye in real time and controls the laser so that it is delivered accurately to the target point. Even if the eye moves during the procedure, its position is immediately corrected for safe vision correction without error.

❹ AI heat-dispersion system

AI heat-dispersion system

Disperses heat while maintaining eye safety

It is equipped with an AI heat-dispersion system that automatically analyzes laser energy to maintain a consistent corneal temperature. This feature prevents subtle heat buildup and minimizes cellular damage, significantly reducing postoperative pain and the incidence of inflammation. This is why stability is maintained even at high speeds.

❺ 3D coordinate-based SmartPulse Technology

A method of delivering laser treatment based on the cornea's three-dimensional spherical structure

Precisely delivers laser treatment in three dimensions according to the shape of the human eye. By reducing the roughness of the corneal surface after the procedure, it promotes faster recovery and improves visual quality, helping secure clearer vision. It enhances procedural stability and increases the likelihood of achieving the target vision.

[Conventional Method]

Laser treatment is delivered in a 2D (planar) manner, which may leave the corneal surface rough.

[NEW 'SPT' Method]

Polishes the corneal surface more smoothly and evenly to promote rapid visual recovery immediately after surgery and reduce glare

Germany's SCHWIND SIRIUS

3D precision diagnostics that reads each individual's eye structure in depth

Analyzes corneal curvature, thickness, and refractive errors in three dimensions, while simultaneously imaging the front and back of the cornea to diagnose the eye's structure in 3D before surgery. It designs optimal correction outcomes using a personalized vision map based on precise data. By establishing a correction plan precisely suited to each individual's eye structure, accurate diagnosis produces precise results.

❶ 3D optical tomography

Reading the eye in three dimensions, even beyond visible areas

3D Corneal Topography technology simultaneously scans the front and back surfaces of the cornea. It precisely analyzes three-dimensional data including subtle asymmetry, curvature, and distortion that cannot be identified with the naked eye, enabling accurate diagnosis.

❷ Wavefront Aberration Analysis

Analyzing the causes of glare numerically

Precisely measures refractive errors throughout the eye (higher-order aberrations) to accurately identify the causes of blurred vision and glare. This data is directly reflected in AMARIS RED surgical planning to help restore clear, sharp vision.
