[Corneal flap analysis after LASIK and femto-LASIK using optical coherence tomography and optical sections]

Two groups of patients were enrolled into the study, each group included 15 patients (30 eyes). Evolution 3E mechanical microkeratome ("Moria") was used to create LASIK flaps in the 1st group. VISUMAX laser microkeratome ("Carl Zeiss Meditec") was used in the 2nd group. Optical coherence tomography showed irregularity of flap thickness in the 1st group. In the 2nd group flap thickness was regular. According to Pentacam data the posterior corneal surface had no postoperative changes in both groups.
