Overlay imaging for registration of a patient eye for laser surgery

Abstract:

Methods and systems for overlay imaging for registration of a patient eye for laser surgery include aligning and overlaying a surgical image of the limbus over a previously acquired diagnostic image of the limbus. The surgical image is displayed with a degree of transparency and enabled to rotate about the limbus center. Various types of colors, markers, contrast, and backgrounds may be used to generate a display for determining the alignment angle between the diagnostic image and the surgical image.
