[Application of femtosecond laser in corneal refractive surgery].

The function of photo-decomposing of femtosecond laser makes it useful in creating precise "cuts" at arbitrary locations within the corneal of almost any conceivable geometry. The applications of femtosecond laser include intrastromal photorefractive keratectomy, creating the pre-cut channels for intra-corneal ring segment, creating lamellar flaps for laser in situ keratomileusis, performing femtosecond lamellar keratoplasty, which represent an entirely new approach for the correction of refractive errors.
