Sony patents eye surgery display that tracks patient's eye movement

Sony describes a system for eye surgery that tracks a patient's eyeball in real-time video. It creates a visual guide on the screen with rings or lines that move to show specific positions or sizes relative to the eye.

Why it mattersThis tool could help surgeons see exactly where they are operating on the eye by adjusting the visual overlay as the patient's eye moves.

In the filing’s own words

An image processing apparatus ( 13) according to one form of the present disclosure includes: an image input unit ( 13 b) that receives an operative field image for an eye of a patient; an eyeball tracking unit ( 13 e) that tracks an eyeball in the operative field image; and a display image generation unit ( 13 f) that sets a plurality of regions having different display modes for the operative field image and generates a display image in which an annular or radial boundary in the plurality of regions indicates a specific position or a specific size with respect to the eye. The display image generation unit ( 13 f) changes a position or a size of the boundary on the basis of a tracking result of the eyeball and generates the display image.

What exactly they claim (claim 1)

1. An image processing apparatus comprising: processing circuitry configured to: receive an operative field image for an eye of a patient; track an eyeball in the operative field image; set a plurality of regions of the operative field image, the plurality of regions having different display modes; generate a display image including the plurality of regions of the operative field image in which an annular or radial boundary formed by the difference in the display modes between the plurality of regions of the operative field image indicates a specific position or a specific size with respect to the eye; and change a position or a size of the boundary on the basis of a tracking result of the eyeball, wherein the processing circuitry is configured to generate the display image based upon the changed position or the changed size of the boundary.
