Corneal flap thickness and topography changes induced by flap creation during laser in situ keratomileusis

The LSX One microkeratome was the most predictable. A significant difference was noted in all sectors except superiorly with the M2 and in all sectors with the Amadeus. No differences between nasal and superior hinge placement were found with the M2. Topographic Zernike analysis demonstrated a difference in the orientation of the induced coma as a function of hinge position.
