How is SMILE different from Femto LASIK?
So, what is a femtosecond Laser?
A femtosecond is 1-15 of a second or 0.0000000000000001 second. Every pulse in a ‘femtosecond laser’ takes less than one trillionth of a second
These ultra short pulses of laser light are extremely gentle on the cornea.
In Smile a ‘lenticule’ is prepared in the intact cornea with a femtosecond laser. This is the actual treatment.
Everything takes place in a closed environment. This ‘lenticule’ is removed through a very small keyhole opening. All this is done without a flap [no large cut], no pain and a quick recovery. With one single system : the Visumax femtosecond laser.
In Femto LASIK, a flap is made with the Femtosecond laser, the flap is lifted and only after that an excimer laser [not the Femtosecond one] shoots treatment can take place. So, you have a flap, in an open environment.
