The WaveLight® FS200 femtosecond laser (Alcon, USA) is an innovative laser technology that enables corneal flap creation while minimizing surgical risks and increasing flap precision, in contrast to the mechanical flap creation method used in LASIK.
The WaveLight FS200 femtosecond laser uses high-frequency operation for efficient flap creation with low flap thickness deviation; a small focus spot and a special cutting pattern minimize opaque bubble layers (OBL); and low pulse energy ensures sharp incision edges, a smooth stromal bed, and facilitates easy flap lifting.
The WaveLight FS200 femtosecond laser enables:
- Sub‑Bowman keratomileusis;
- Intrastromal tunnels for segments and rings;
- Flap creation (a platform allowing various cutting patterns);
- Keratoplasty – lamellar (layer‑by‑layer), penetrating (particularly for deeper penetration required with thick donor tissue), and through‑and‑through, which can be performed using customizable patterns.
The WaveLight FS200 femtosecond laser utilizes an optimal repetition rate and a specialized position control algorithm to operate at optimal energy levels while also reducing positioning requirements, enabling efficient procedure performance. The productivity of the photodisruptive effect, combined with an enhanced induced shock wave, ensures leadership in tissue separation technology at minimal impact energy.
Enhanced pass management technology applied for surgical efficiency enables:
- Use of a single overlapping pass to reduce induced errors;
- Optimization of cut lines and points for smoother surfaces;
- Uniformity of laser pulses through PerfectPulse Technology™, even with customized separation profiles;
- Advanced OBL (opaque bubble layer) management with reduced OBL spread for higher‑quality procedures.
Advanced vacuum technology with optimized vacuum‑on and vacuum‑off times improves patient comfort and enhances visual recovery, thanks to an innovative vacuum ring and patient interface design.
Unique Patient Interface:
- The specially shaped patient interface fits both normal and deep‑set eyes. This shape also allows creation of large flaps (up to 10 mm), which is particularly important for hyperopia correction;
- The patient interface design also incorporates a special flat surface that ensures uniform energy delivery, including at the periphery;
- Automatic calibration of each interface is performed using laser interferometry before each procedure to minimize the effect of interface glass thickness and improve result consistency.
The WaveLight FS200 femtosecond laser creates consistently high‑quality flaps by reducing flap thickness deviation from the central zone to the periphery.
A high‑precision position control algorithm and Gaussian beam shape ensure smooth incisions without depressions or protrusions.
Automatic daily calibration of the WaveLight FS200 femtosecond laser ensures reliable and stable operation throughout the surgical day.
Sensors that measure at multiple points along the laser path guarantee energy quality to maintain high‑quality spot formation and pattern consistency.
A high‑resolution microscope provides unparalleled, uninterrupted viewing throughout all procedure stages, with preset magnification options. A user‑friendly interface, with a short learning curve, enables monitoring of all procedure stages through the microscope or on the monitor to ensure patient safety. The S‑Video output also serves as an aid for displaying information or video.
The convenient operator interface, which is an integral part of the laser, includes a keyboard, control panel, and high‑resolution monitor.
