Femto-Visum®

Femtosecond lasers generate pulses of 10-15 sec. This extremely short pulse duration provides photodisruption of the tissue with no thermal damage. High quality corneal flap creation is achieved through the dynamic scanning algorithm and special optics minimising the diameter of the laser spot in the focal plane.
