  • Patent number: 8287486
    Abstract: An infusion pressure monitoring system for a phacoemulsification or vitrectomy machine to be operated by a health care provider includes an irrigation path configured to carry an irrigation solution to a surgical site and a fluid sensor configured to detect a fluid parameter in the irrigation path. An input device receives a variable fluid flow command from the health care provider commanding an irrigation fluid flow through the irrigation path at a flow rate corresponding to the command. A controller communicates with both the fluid sensor and the input device. The controller determines an expected fluid pressure value and a dynamically variable threshold pressure value based upon the variable fluid flow command.

  • Patent number: 8257307
    Abstract: A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.

  • Patent number: 8182435
    Abstract: An implantable intraocular pressure sensor system has a sealed geometric shape with an internal pressure at a first value. A strain gauge wire is embedded in a surface of the sealed geometric shape. When the surface is deflected by intraocular pressure, a measured resistance of the strain gauge wire indicates the intraocular pressure. The system also has a processor coupled to a power source and memory. The processor is configured to read the measured resistance and write values corresponding to intraocular pressure to the memory.

  • Patent number: 8118790
    Abstract: The present invention is an ophthalmic injection system with a limited reuse assembly and a tip segment. The tip segment is connectable to and removable from the limited reuse assembly. The tip segment includes a dispensing chamber, a plunger, and a housing. The dispensing chamber holds a quantity of a substance to be injected into an eye. The proximate end of the plunger has a first mechanical linkage interface. The limited reuse assembly of the ophthalmic injection system has a power source, a controller, a motor, a second mechanical linkage interface located on an end of the motor shaft; and a second housing. The first mechanical linkage interface is mateable with the second mechanical linkage interface such that when the tip segment is connected to the limited reuse assembly, the first mechanical linkage interface mates with the second mechanical linkage interface so that motion of the shaft results in motion of the plunger.

  • Patent number: 8070711
    Abstract: A control system for managing power supplied to a phacoemulsification hand piece includes a power source that provides power to the hand piece and a controller that controls the power source. The controller calculates a thermal value based on irrigation fluid flow and a power level and decreases the power level in proportion to the calculated thermal value when the calculated thermal value exceeds a threshold thermal value. Irrigation fluid flow can be calculated from irrigation fluid pressure.
