The Cassini Guidance System is a digital surgical guidance platform that uses preoperative iris imaging from the Cassini Ambient (topographer ) to provide real‑time intraoperative alignment for toric IOLs and corneal incisions. This image-based system allows the planned astigmatic correction to be delivered at the true anatomic axis of the eye, compensating for cyclotorsion, head tilt, and pupil shift between diagnostic imaging and surgery.
