The ultra-fast iFS 150 femtosecond laser uses an infrared light beam of 1053nm,
generating 30,000 pulses per second, to prepare the intracorneal bed and
create the corneal flap in the first step of LASIK (Femto-LASIK).
The laser can also be used to create corneal pockets to implant ICRS.
The femtosecond laser eliminates the need for the doctor to use a blade
at all. Instead, this computer-controlled laser technology works by delivering
rapid pulses of infrared laser energy, a quadrillionth of a second each,
to a pre-programmed depth and position within the cornea. The iFS 150 enables the doctor to precisely design and control many aspects of the
flap itself, such as its thickness, its circumference, and the angle of
its edges, effectively tailoring the flap to the eye. This is of particular
benefit to patients with steep, flat, or thin corneas, some of whom are
not eligible for LASIK surgery performed with a microkeratome.
The degree of accuracy achieved by the femtosecond laser is unprecedented
in flap creation technology. Peer reviewed studies demonstrate that the femtosecond laser technology eliminates the possibility of the most serious sight-threatening
complications associated with laser eye surgery.
