摘要：A positioning assembly for retaining, positioning and at least partially exposinga cornea of an eye during a surgical procedure, the eye being disposed in a latitudinallynarrowed ocular access. The positioning assembly includes a positioning segment having
a retention plate with an aperture defined therein to receive and expose the cornea ofthe eye, and a flange member disposed about the aperture, a closely spaced apartdistance from a latitudinal radius thereof, and structured to engage the eye. The
positioning assembly further includes a suctioning assembly operably associated with thepositioning segment for at least temporarily attaching the positioning segment to theeye, the suctioning assembly including a vacuum port extending vertically from thepositioning segment and angled outwardly away from a guide track integrally disposedon the retention plate to define an arcuate cutting path for a microkeratome cuttinghead assembly. A pivot assembly including at least a post member is further provided,the post member defining a pivot axis about which a coupling assembly, which operablyinterconnects the cutting head assembly and the post member, pivots. A cut originationcontrol is provided at the post member to define an origination point at whichmovement, and accordingly cutting, by the cutting head assembly begins.
