Create Anatomically Correct Flap Creation With the IntraLase Method™*(1)

IntraLase Microkeratome Flap Shape/ Diameter Planar flap† Meniscus-shaped flaps Hinge Size and Shape Software settings can be adjusted and tailored. The use of a stromal pocket allows the flap to be retracted further, thus making more surface area available for a flap of any given diameter. A D-shaped stromal bed is created, leaving less room for the flap diameter. Side Cut Angle The side cut angle can be varied from 0º to 90º. An increased side cut angle can allow the flap to seat more easily and, more importantly, create a powerful barrier to epithelial cell migration. Edge configuration is 25º to 35º—a necessary angle with a blade to avoid deep penetration or anterior perforation. Flap Thickness Predictable: Corneal applanation provides a fixed reference plane Variable and may be affected by: An oscillating blade Corneal curvature Keratome translation speed

†Evidence shows that planar flaps may offer better refractive outcomes, as less induced cylinder and higher-order aberrations seem to occur when compared to meniscus-shaped flaps created by mechanical microkeratomes.(2-4)

*Only the IntraLase® FS laser can be used to perform the IntraLase Method.
