Digital guidance provides a live overlay in the operating microscope, helping me position your lens with precision. I have experience using both the VERION and CALLISTO systems and I currently employ CALLISTO z‑alignment at Moorfields Private Eye Centre, 50 New Cavendish Street.

For the technically minded: Systems such as Zeiss CALLISTO eye and Alcon VERION register limbal landmarks and scleral vessels from pre‑operative images, projecting intra‑operative alignment cues. Sub‑degree rotational accuracy improves toric axis placement and centration of multifocal optics.
