Pressure-Sensing Vitrectomy Surgical Systems and Methods

A vitrectomy surgical system comprising:

• a vitrectomy probe having a cutting portion comprising an inner cutting tube, an outer cutting tube, and an outer port, the inner cutting tube being movable relative to the outer cutting tube to cut vitreous humor during a vitrectomy procedure;
• a motor configured to move the inner cutting tube relative to the outer cutting tube to open and close the outer port;
• and
• one or more pressure sensors coupled to the vitrectomy probe to measure one or more pressures associated with the vitrectomy probe.

A method of treating an ophthalmic condition, the method comprising:

• inserting a probe through a sclera into a vitreous chamber of a patient, the probe including at least one pressure sensor;
• measuring a vitreous chamber pressure with the at least one pressure sensor to provide a vitreous chamber pressure measurement;
• and
• adjusting a parameter of a vitreous humor removal procedure based upon the vitreous chamber pressure measurement.
