What the trial is, and whether it could suit you

This study aims to assess the accuracy of toric intraocular lens (IOL) alignment axes as calculated and displayed by a novel digital guidance system. In addition, it evaluates the time required to initiate surgical guidance and postoperative refractive astigmatism following toric IOL implantation. This 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). Postoperative outcomes, including residual refractive astigmatism (diopters) and visual acuity (Snellen), were recorded at 1 month postoperatively.
