Femtosecond laser technology has revolutionized eye surgery. This technology has been widely and increasingly adopted by refractive and cataract surgeons, originally for the creation of the laser in-situ keratomileusis flap secondary to its improved safety and clinical outcomes. Other applications include astigmatic keratotomy, channel creation for intracorneal rings, femtosecond lenticule extraction, corneal inlays and intrastromal presbyopia correction. The latest is the use of femtosecond technology during cataract surgery and corneal transplantation. The success of this technology lies in the fact that it is precise and reproducible. Flap creation with femtosecond laser over that of a microkeratome is due to better contrast sensitivity, increased safety, faster uncorrected visual acuity recovery, less induced aberrations and less IOP variation. There is also a lower incidence of dry eyes post femtosecond LASIK.
