Today, the Femtosecond Laser has entered the quiver of refractive surgeons. The Femtosecond Laser uses pulses of light, which penetrate the surface of the cornea and form small cavities (bubbles) at a predetermined depth and position within the corneal layer. The result of the application of the Femtosecond Laser is the creation of a uniform layer of bubbles inside the cornea. Using a special spatula, the final separation of the flap from the rest of the cornea is done. The surgeon can then apply the treatment with the Excimer Laser.
Compared to mechanical microkeratomy, the creation of the flap using femtosecond technology is a more predictable and more controlled process. The thickness, the diameter, the angle of the flap borders, the position in which it remains attached to the cornea (stem / hinge) as well as the angle of the stem are defined by the surgeon before the application of the Femtosecond Laser.
Continuous technological development has also helped to dramatically improve the technical characteristics of Excimer Lasers. The new machines have the ability to use a very thin laser beam, which “flies” in different parts of the cornea (flying-spot Laser). Thus, it allows more detail in the operation. The speed of the machines has also been increased, so that the treatment time is minimized.
Finally, individualized treatments can be applied according to the needs of each eye separately (wavefront-optimized & wavefront-guided treatments). These treatments are used in conjunction with corresponding diagnostic machines that have introduced refractive surgery into the fascinating world of Wavefront-guided / optimized & Topography guided customized ablation.
The operation is now done to the measure of each eye and is not the same for all those who have the same recipe in their glasses.
“Diathlasis” uses exclusively the Femtosecond Laser VisuMax by ZEISS, a system that in combination with the Wavelight EX500 Excimer Laser by ALCON, unique in Northern Greece, offers excellent clinical results and greater comfort for patients during ocular surgery.
