Femtosecond LASIK

Laser vision correction (also known as "refractive surgery") improves eyesight by using an excimer laser to change the way light is focused or refracted by the eyes. The most common type of refractive surgery is Laser-Assisted In-Situ Keratomileusis (LASIK).

In the first step of the LASIK procedure, surgeons mechanically create a corneal flap, a mirco-thin flap of tissue on the outer layer of the cornea, using a mechanical device called a microkeratome. With Femtosecond (FS) LASIK, the surgeon uses a computer-guided femtosecond laser to create the corneal flap.

The Femtosecond (FS) Laser uses tiny beams of laser light to safely and accurately create a layer of gas bubbles in the cornea. This allows the surgeon to perform “all laser LASIK,” using two different lasers for the two steps of the procedure: the femtosecond laser to make the flap, and the excimer laser to contour the cornea’s curvature, adjusting its focusing power.

The process can be up to 100 times more accurate, resulting in fewer complications and allowing patients a higher degree of comfort.

The safety and accuracy of Femtosecond LASIK allows treatment of a broader range of people, including those who were not good candidates for the traditional LASIK procedure due to the thickness of their cornea or to slightly dry eyes.
