In addition, it evaluates the time required to initiate surgical guidance and postoperative refractive astigmatism following toric IOL implantation.\n\nThis single-surgeon, single-site, prospective, non-invasive observational study evaluated the accuracy of toric IOL alignment axes calculated and displayed by the digital guidance system (Cassini Technologies, B.V.) in 100 eyes. The intraoperatively calculated alignment axes were compared to preoperative measurements to assess their accuracy (in degrees).
