Abstract: An ophthalmic illumination system comprising a multimode fiber optic having an end a first laser source, and the system configured to project light into the end at a plurality of different angles. An ophthalmic illumination system comprising a multimode fiber optic having an end, a first light source adapted to produce light of a first color, a second light source adapted to produce light of a second color, and a beam combiner configured and arranged to receive and combine the light from the first light source and the light from the second light source to form a combination of light. The beam combiner is configured and arranged to project the combination of light into the end. The system is adapted to vary at least one of the amount of the light of the first color and the amount of the light of the second color projected into the end, such that the combination of light has a selectable color.

Abstract: A flow control device includes a housing having a motor chamber and a pump chamber. The motor chamber has an outlet for communication with a fluid collection device, and an inlet for communication with an aspiration line through which fluids are delivered into the motor chamber. First and second motor rotors are rotatably disposed in a flow path between the inlet and the outlet in the motor chamber, and a drive shaft is coupled to the first motor rotor. The pump chamber has an outlet for infusing fluid to a surgical site, and an inlet through which infusion fluids are delivered into the pump chamber. First and second pump rotors are rotatably disposed in a flow path between the inlet and the outlet in the pump chamber, where the first pump rotor is coupled to the drive shaft. The drive shaft drives the pump rotors at the same speed as the motor rotors, such that any surge in aspiration flow induces a similar surge in infusion flow.

Abstract: A flow control device for providing flow resistance to a surgical handpiece during ophthalmic surgery. The flow control device includes a chamber having two sides in parallel separated by a height, an inlet port extending tangentially from the chamber in parallel with the two sides for coupling to a surgical handpiece, and an outlet port extending from about the center of the chamber perpendicular to the two sides for coupling aspiration tubing.
