Improving Outcomes

The Hill-RBF Method 3.0.

Now available exclusively on all Lenstar devices.

The Hill-RBF Method 3.0 is driven by a foundation built on the collection of IOL data from leading cataract surgeons across the globe. This big data is analyzed by artificial intelligence-based pattern recognition to produce highly accurate and confident IOL predictions. The result: improved measurement accuracy for normal eyes, and now includes predictions for even more eyes with unusual anterior segments, high axial myope, and hyperope.

Hill-RBF is the only IOL power calculation method providing you with an out-of-bound message—a confidence marker—indicating an extremely long or short eye. Fortunately, the number of out-of-bound indications for most cataract surgery patients has been dramatically reduced due to the incorporation of lens thickness, WTW, CCT, and patient gender parameters.

Barret & Olsen Formulas

Measured lens thickness and two of the latest generation multivariable IOL formulas allow for premium IOL power prediction with the Lenstar 900.


T-Cone Toric Platform

The optional T-cone complements Lenstar 900’s measurement pallet with true Placido topography of the central cornea and a powerful surgical planner using the Barrett Toric Calculator.


EyeSuite IOL Toric Planner

The optional IOL Toric planner allows optimization of the incision location and planning of the surgery on real eye images to reach advanced refractive results.

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.”
