EyeSuite IOL provides excellent IOL calculation and enables improved outcomes for spheric, toric, and multifocal-IOL with any patient.
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.
Standard formulae use axial length and K measurements to calculate IOL power, limiting their performance with unusual eyes. Barrett and Olsen use more parameters, including anterior chamber depth and lens thickness to estimate implant power. This improves the prediction of the implant position and enables better results, independent of the patient anatomy.
Unlike most standard formulae, the Universal II formula is a thick lens formula, taking into account the changes in optics design of IOLs at different powers. In addition to AL and Ks, it uses ACD, lens thickness and white-to-white measurement to predict the lens position and IOL power, leading to excellent refractive outcomes in all patients.
The Olsen formula uses ray tracing, a method well known from optics design, to calculate lens power and the concept of the C-constant to predict implant location. As an input parameter, apart from AL and Ks, Olsen uses ACD and LT measurement enabling excellent implant position prediction in all eyes.
