New Technique : Femtosecond Lenticule Extraction. Different To LASIK

Femtosecond Lenticule EXtraction ( FLEx ) is a completely new technique for laser vision correction designed for the correction of myopia. It is similar to Intra Femtosecond LASIK that creates a lenticule for removal and a corneal flap. However, unlike the traditional LASIK, the FLEx involves using the femtosecond laser to cut a refractive lenticule in the same step as the flap creation, but it is peeled off the corneal bed, rather than being ablated and being converted into a gas with the excimer laser of the traditional LASIK. In addition, the breakthrough is that the FLEX may be reversible.

  1. FLEx has made protecting the cornea's integrity easier and creating flaps more consistent and precise.
  2. FLEx may be more accurate than LASIK when correcting relatively high amounts of myopia.
  3. FLEx may induce fewer higher-order aberrations than LASIK or PRK , for sharper vision overall, and especially at night.
  4. FLEx works even better for those with more severe myopia of up to 1,000 degrees.
  5. FLEx may be reversible.

How FLEx Works

Step 1. The femtosecond laser creates a refractive and a nonrefractive cut in a single step.
Step 2. After the flap is lifted, a piece of stromal corneal tissue (ie, refractive lenticule) is removed.
Step 3. The flap is repositioned in the usual fashion.

Currently, the FLEx procedures has received a CE Mark in Europe. The near future, it will substitute of older femtosecond lasers like the Intralase.
