    Abstract: In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.
