Corneal topographer SeeNa™

optical biometertabletop

SeeNa™ captures nine key measurements to calculate IOL power and predict effective lens position...all with a single acquisition. Axial length Keratometry Anterior chamber depth Central corneal thickness Lens thickness Corneal topography Corneal wavefront analysis Photopic and mesopic pupillometry Corneal white-to-white measurements Bausch + Lomb’s Cataract Workflow Bausch + Lomb offers efficient, affordable solutions for pre-surgical evaluation and planning as well as post-operative follow up. Using the SeeNa™ biometer and corneal topographer gives surgeons the tools needed to plan for surgery and assess visual outcomes.
