Real-Time Instrument Position Estimation and Guidance for Ophthalmic Surgery

A method for an ophthalmic surgical procedure, comprising:

• obtaining, via an intra-operative imaging system, images of an eye during the ophthalmic surgical procedure, the intra-operative imaging system comprising a first camera and a second camera having different viewpoints of the ophthalmic surgical procedure;
• processing the images of the ophthalmic surgical procedure in real-time to determine a relative position of a targeted instrument feature with respect to a targeted anatomical feature of the eye;
• and
• outputting a surgical guidance in real-time based on the relative position of the targeted instrument feature with respect to the targeted anatomical feature of the eye.

An ophthalmic surgical system comprising:

• an intra-operative imaging system to obtain images of an ophthalmic surgical procedure performed on an eye, the intra-operative imaging system comprising a first camera and a second camera;
• and
• a real-time instrument position estimation module implemented in a non-transitory computer-readable storage medium and configured to perform operations comprising:
• determining, in real-time as the images are obtained, a relative position of an instrument feature with respect to an anatomical feature of the eye based on the images, pre-operative measurements of the eye, and an arrangement of the first camera and the second camera in the intra-operative imaging system;
• and
• outputting, in real-time as the images are obtained, a surgical guidance based on the relative position of the instrument feature with respect to the anatomical feature of the eye.
