Abstract:

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An ophthalmic surgical system may include a vitreous probe having a housing sized and shaped for grasping by a user. The vitreous probe may also include a cutter extending from the housing and being sized to penetrate and treat a patient eye. The cutter may include an outer cutting tube coupled to the housing. The outer cutting tube may have an outer port formed at a distal end wall of the outer cutting tube and configured to receive tissue. The cutter may include a rotatable inner cutting member disposed within the outer cutting tube. The inner cutting member may include a first cutting surface that rotates across the outer port to cut the tissue when the inner cutting member is rotated.
