Abstract: A system for guiding an ophthalmic procedure is disclosed. The system includes a housing assembly with a head unit configured to be at least partially directed towards a target site in an eye. An optical coherence tomography (OCT) module and stereoscopic visualization camera are at least partially located in the head unit and configured to obtain a first set and a second set of volumetric data, respectively. A controller is configured to register the first set and second set of volumetric data to create a third set of registered volumetric data. The third set and second set of registered volumetric data are rendered, via a volumetric render module, to a first and second region. The first region and the second region are overlaid to obtain a shared composite view of the target site. The controller is configured to extract structural features and/or enable visualization of the target site.

Abstract: A method for enhancing digital images during a microsurgery, e.g., an eye surgery, includes collecting digital images of target anatomy using a digital camera as the target anatomy is illuminated by warm white light. The method includes identifying, via a processor in communication with the digital camera, a predetermined stage of the microsurgery. Within the images, the processor digitally isolates a first pixel region, e.g., a pupil pixel region, from a second pixel region, e.g., an iris pixel region, and adjusts a characteristic of constituent pixels thereof. The method, possibly recorded as instructions in a computer-readable medium, may be used to enhance a red reflex at predetermined stages of an eye surgery. A system includes a lighting source for emitting warm white light having a color temperature of less than about 4000° K, the camera, and the processor.

Abstract: A method of calibrating a robotic imaging apparatus includes providing the robotic imaging apparatus, calibrating a stereoscopic camera portion of the apparatus to robot space, and registering the robot space to a patient space. An embodiment of the apparatus includes a base section defining the robot space, a robotic arm including a first end connected to the base section, a second end including a coupling interface, and a plurality of joints and links connecting the first end to the second end, each joint including a motor configured to rotate the joint around an axis and a joint sensor configured to transmit a position of the respective joint, a stereoscopic camera connected at the coupling interface, and a sensor positioned at the coupling interface and configured to detect force imparted on the stereoscopic camera by an operator and to transmit output data indicative of the detected force.

Abstract: A visualization system for an ophthalmic procedure on a target eye, e.g., lens replacement surgery, includes first and second light sources respectively operable for directing visible and NIR light toward the target eye. A hot mirror directs reflected light from the eye along two paths, i.e., a visible light path for reflected visible light and an NIR light path for reflected NIR light. First and second cameras are respectively positioned in the visible and NR light paths to detect the reflected visible or NIR light and output a visible or NIR image. An electronic control unit (ECU) executes a method to detect a perimeter edge of an imaged portion of the target eye in the NIR image using edge detection logic, merges the visible image with the NIR image to construct a combined image, and indicates the perimeter edge in the combined image.
