Improving Outcomes

The Hill-RBF Method 3.0
now available exclusively on all Lenstar devices

IOL data from all over the world collected by leading cataract surgeons is the foundation for the Hill-RBF. This big data is analyzed by pattern recognition based on artificial intelligence leading to highly accurate IOL predictions and providing confidence thanks to a unique reliability check. Hill-RBF is the only IOL power calculation method providing you with an out-of-bound message, a confidence marker, when it comes to an IOL power collection of an extreme case, i.e., extremely long or short eye.

The LENSTAR LS 900 puts everything I need at my fingertips with one device. It’s the only biometer that has the Hill-RBF seamlessly integrated into its software. The accuracy of the built-in Barrett and Olsen IOL calculation formulas vastly surpasses the pre-millennium formulas used in other biometers. And its T-Cone topography permits rapid assessment of the relative regularity of the cornea and tear film, crucial for screening and managing premium IOL candidates.”
