Abstract: Both visible and IR cameras are integrated without an increase in an optical stack height of a surgical microscope used for ophthalmic surgery. The IR camera may be used to directly and intraoperatively capture a scanning OCT measurement beam, which uses NIR light that is invisible to the human eye. An IR image from the IR camera taken from the same surgical field as displayed intraoperatively to a user of the surgical microscope may be displayed in an ocular to the user, enabling visualization of a location of an OCT scan along with actual visible images of the surgical field.

Abstract: A foot-operated controller includes a base configured to rest on a floor surface, and a movable contact surface coupled to the base. The contact surface includes an anterior region to support a toe region and a posterior region to support a heel region, and is configured to roll about a roll axis in response to inversion or eversion of a foot engaged with the contact surface, pitch about a pitch axis in response to plantar flexion or dorsiflexion of the foot, and yaw about a yaw axis in response to abduction or adduction of the foot. The roll, pitch, and yaw axes intersect at a point superior to the contact surface, and may align with the operator's ankle.
