Optical Biometry & Topography System

9 in 1 Features

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.
