Corneal Topographer

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.
