Surgeons at the Mayo Clinic and elsewhere are operating with a new laser retinal-imaging device, Microvision’s Nomad, which “paints” images and data directly onto their eyes.

Information taken from X-rays, MRIs or CAT scans can be displayed as high-contrast, high-resolution, full-color images superimposed directly over the target area on the patient’s body to help guide the surgeon’s hands through the procedure.
