Abstract
A system includes an imaging device configured to perform three-dimensional imaging of at least a portion of an eye of a patient, such as one or both of an OCT and a 3D camera. A sensor is configured to sense a location of a trocar cannula positioned in the eye of the patient. A controller is configured to receive one or more three-dimensional images from the imaging device and receive coordinates of the trocar cannula from the sensor. The controller generates a three-dimensional map of the eye from the one or more three-dimensional images and the coordinates, the three-dimensional map including a representation of the trocar cannula. The controller further generates guidance for performing an ophthalmic procedure according to the three-dimensional map, such as an instrument envelope and / or instrument path. The controller outputs the guidance to a display device or uses the guidance to control a robotic arm.
