A Femtosecond laser is a specialized laser used for eye surgery and other medical and technical applications.

The word “Femtosecond” refers to the units used to measure the duration of each pulse. One Femtosecond is equal to one millionth of one billionth of a second, or one millionth of a nanosecond.

Femtosecond laser offers greater precision and control than a bladed microkeratome when creating a corneal flap. LV Signature LASIK, thereby, reduces the risk of flap complications during conventional LASIK surgery.

Though flap complications from the use of a bladed microkeratome are infrequent, a risk remains for undesired outcomes such as partial flaps (due to the mechanical microkeratome during flap creation, button hole flaps (a too-thin flap with a hole in its center) and free caps (a flap with no hinge to keep it attached to the eye).

These types of flap complications are virtually eliminated when a femtosecond laser is used to create the corneal flap in all-laser LASIK.
