Femtosecond laser in laser in situ keratomileusis [PDF]
Journal of Cataract and Refractive Surgery, 2010 Flap creation is a critical step in laser in situ keratomileusis (LASIK). Efforts to improve the safety and predictability of the lamellar incision have fostered the development of femtosecond lasers. Several advantages of the femtosecond laser over mechanical microkeratomes have been reported in LASIK surgery.
