One recent and interesting technical development in laser refractive surgery is the emergence of ultrashort pulse lasers. The femtosecond laser is a focusable infrared laser using pulses in the femtosecond (10−15s) duration range. This laser delivers closely spaced spots that may be focused at a preset depth to photodisrupt tissue within the corneal stroma.Flap creation for LASIK represents the first clinical application of the femtosecond laser. The potential advantages of the femtosecond laser over the microkeratome include precise flap thickness , and reduced incidence of flap complications, such as buttonholes, epithelial abrasions, short flaps, free caps, blade marks, and irregular cuts.A femtosecond laser provides an effective and safe procedure for LASIK treatment of myopia. This technology also improves contrast sensitivity and avoids the negative effect on visual performance found after microkeratome LASIK.
