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.
