Precisio™ – High Definition Surgical Tomography

The unique tomographer for custom vision surgery.

Designed in-house to be fully integrated into the iVis Suite™, Precisio™ is iVis new generation Corneal Tomographer.

Precisio™ delivers true HD morphological maps and refractive data with statistically validated repeatability.

Precisio™ is equipped with our exclusive iVerify™ application to grant, by means of a statistical analysis based on AI principles, an automated and objective analysis of the morphological and refractive corneal surgical outcomes.

Precisio™ is based upon effective 6D tracking of 60 HD cross-section images acquired in less than 1 second to provide morphological and refractive data of each corneal sublayer with unmatched accuracy and repeatability.

Thanks to its patented blue scanning laser micro-slit, Precisio™ is the unique medical device featuring full registered and validated epithelial maps up to 10.0 mm diameter.

Precisio™ provides , through a ray-tracing process, the true total corneal power including corneal high order aberrations.

Precisio™ identifies the corneal pathologies and differentiates between stable and ectatic diseases by means of a dedicated diagnostic analysis. A clinical follow-up application allows to monitor the evolution of the corneal pathology.
