In one embodiment, a phacoemulsification system includes a phacoemulsification probe configured to be inserted into an eye, an ophthalmic curette, including a handle, a tube having a proximal end connected to a distal end of the handle, and having a distal tip configured to be inserted into the eye, an irrigation channel extending from the proximal end to the distal tip of the tube, and a pressure sensor disposed at the distal tip of the tube, and configured to be inserted into the eye and provide a signal responsively to intraocular pressure inside the eye, and comprising a sensing surface, and an irrigation-aspiration sub-system coupled with the irrigation channel and configured to convey irrigation fluid along the irrigation channel, and wherein the irrigation channel is shaped, and positioned with respect to the pressure sensor, to direct a flow of the irrigation fluid over the sensing surface of the pressure sensor. |
