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.
