Abstract: A system for performing ophthalmic surgery includes a robotic positioning system including an end effector. The robotic positioning system is configured to position the end effector with at least five degrees of freedom. An ophthalmic surgical instrument is mounted to the end effector along with an accessory device configured to facilitate performance of an ophthalmic treatment by the ophthalmic surgical instrument. The robotic positioning system may be controlled to enforce anatomical boundaries and implement predefined motion profiles.

Abstract: A delivery device includes a conveyor, one or more imaging devices configured to have an eye of a patient in a field of view thereof, and an needle assembly configured to receive a drug to be injected into the eye of the patient. A staging assembly is mounted to the conveyor and includes one or more actuators configured to position the needle assembly relative to the eye of the patient. A controller is configured to receive one or more images from the one or more imaging devices; detect a location of anatomy of the eye of the patient in the one or more images; and activate the one or more actuators to drive a needle mounted to the needle assembly into a placement location on the eye of the patient according to the location of the anatomy. The controller activates the needle assembly to inject fluid into the eye or draw tissue out of the eye.

Abstract: A system for performing ophthalmic treatments includes a handpiece configured to be held by a hand of a surgeon. An end effector is mounted to the handpiece and configured to manipulate tissue of a patient, such tissues of the eye when performing an ophthalmic treatment. The system includes a motion sensor configured to sense movement of the handpiece and one or more stabilizing actuators configured to stabilize movement of the handpiece in response to movement of the hand of the surgeon. A controller is coupled to the motion sensor and the one or more stabilizing actuators and is configured to instruct the one or more stabilizing actuators to compensate for motion detected by the motion sensor. The controller may include a high-pass filer with the output of the high-pass filter used to control the stabilizing actuators. The parameters of the high pass filter may be adjusted throughout an ophthalmic treatment.
