Abstract:
A foot pedal device configured to provide force feedback to an operator during ophthalmic surgery is described. The foot pedal device includes a processor and a memory containing instructions which, when executed by the processor, cause the processor to transmit, in response to a movement of a moveable member, a control signal to a surgical console for initiating an action of an ophthalmic surgery tool coupled with the surgical console. The foot pedal device includes a force feedback mechanism configured to selectively apply a resistance force in opposition to the movement of the movable member. The memory contains instructions which, when executed by the processor, cause the processor to receive, from the surgical console, a trigger signal, and send a force feedback signal to the force feedback mechanism. The force feedback mechanism is configured to apply the resistance force to the movable member upon receiving the force feedback signal.
