Femtosecond laser flap creation for laser in situ keratomileusis: six-month follow-up of initial U.S. clinical series.

Purpose: To evaluate clinical performance of a femtosecond laser for flap creation in laser in situ keratomileusis (LASIK).

Methods: A prospective, consecutive series of 208 eyes (122 patients) undergoing LASIK between June 2000 and November 2000 using a femtosecond laser for creation of the corneal flap were evaluated for the incidence of complications. A subset of 114 patients who underwent myopic procedures and who were followed for 6 months was analyzed using standard outcome measures.
