Laser correction with femto assistance (Femto LASIK)

Femto laser-assisted correction involves the use of a femtosecond laser at one of the stages of the procedure, i.e. corneal flap cutting, for a noncontact intervention.

Description of femto assisted correction

Laser vision correction involves reshaping of the curvature of the cornea by excimer laser to change its refractive power. The LASIK method consists in evaporating excess bio material from the median corneal layers. A corneal flap is cut to facilitate access to these layers.
Femto assistance involves replacing cutting with a mechanical tool with separation of tissues by a femtosecond laser.

Femto laser operation during correction

A femtosecond laser uses an infrared beam for a precise separation of tissues at a preset depth via the so-called photo cleavage process. The femtosecond laser sends pulses into the corneal layers to form microbubbles that are positioned alongside each other to form a cleavage plane. After completion of this process, the surgeon opens the flaps to reshape the curvature of the cornea and change its refractive power using an excimer laser.

Creation of corneal flap by a femtosecond laser (Femto LASIK) makes it possible to obtain a smooth surface of the corneal cleavage edge without applying mechanical pressure to the cornea. A corneal flap is created according to the personal parameters of each patient which is impossible to achieve using a mechanical tool.

Advantages of noncontact flap creation:

  • a new and improved quality of contrast and clear vision;
  • capability to accommodate thin corneas;
  • a significantly reduced rehabilitation period;
  • mitigation of risks.

New opportunities given by femto assistance

The capability to precisely cut a corneal flap using a femtosecond laser greatly expanded the scope of laser correction. Now at Excimer, we can offer laser correction to patients with abnormal corneal developments, flat and thin corneas, dry eye syndrome and other complex ocular pathologies. Until recently, these conditions were contraindications to laser correction; now they are not.

Femto assistance greatly enhances the capabilities of the LASIK method. This technique makes it possible to achieve good vision even in the most difficult cases.

Result of laser correction with femto assistance

Laser correction with femto assistance gives you a chance to eliminate myopia, farsightedness or astigmatism, and say farewell to glasses and contact lenses. Your vision recovers on the same day, regardless of the initial degree of myopia, farsightedness or astigmatism.

About 2,5 million femto-assisted laser corrections have already been performed around the world.

When is femto assistance required?

Your attending ophthalmologist will authorize a laser correction technique after comprehensive diagnostics.

Feedback from our patients

Grebenshikova Veronika
Hello, I underwent a surgery (femto LASIK) in late April and I am very happy with the result. I was very nearsighted, but now my vision has almost completely recovered. I am also very impressed with the service and attention from the personnel!
I underwent Femto LASIK correction at Nizhny Novgorod clinic. At first I was afraid because I had been very nearsighted since early childhood. I got really lucky with Excimer. The personnel were very friendly, and the doctor was careful and attentive. I was operated on both eyes, it took about 5 minutes, and all the time the doctors were explaining to me what was going on and keeping comforting me. Everything went quick and smooth. At first I had slight headaches, but they passed quickly, my vision recovered, and soon I was able to go back to work. Now I can see with my own eyes, I even cried I was so happy, and all my fears went away. Many thanks to Excimer, especially to Yulia Sergeevna Kudriavtseva!!!
