A positioning assembly for retaining, positioning and at least partially exposing a cornea of an eye during a surgical procedure. The positioning assembly includes a positioning segment having a retention plate with an aperture to receive and expose the cornea, and a flange member disposed about the aperture and structured to engage the eye. The positioning assembly further includes a suctioning assembly having a vacuum port extending vertically from the positioning segment and angled outwardly away from a guide track integrally disposed on in the retention plate to define an arcuate cutting path for a microkeratome cutting head assembly. A pivot assembly including at least a post member is further provided which operably interconnects the cutting head assembly and the post member. A cut origination control is provided at the post member to define an origination point.
