This is essentially a LASIK procedure that instead of using a bladed microkeratome uses another laser, the Femtosecond Laser to create the corneal flap. The word IntraLASIK was derived from the first Femtosecond Laser to be commercialised, the "Intralase" in use in the USA since 2002 and in Europe since 2004.
Other Femtosecond lasers are available that also create flaps and perform similarly. These include the Victus Femtosecond laser (Bausch+ Lomb), Visumax (Carl Zeiss), Ziemar and Wavelight.
The advantages of the Femtosecond laser is accuracy and in turn safety of flap creation. Flap dimensions are highly accurate in diameter and depth improving predictability and safety. Additionally the flap is "planar" in shape and of equal thickness throughout. This is important in reducing any biomechanical changes in corneal shape that can alter the goalposts for refractive correction - in other words improved accuracy and decreased likelihood of an enhancement.
The preoperative evaluation process is similar to LASIK. Please refer to LASIK under procedures.
