I ARTIFICIAL INTELLIGENCE N FOCUS 40 | EYEWORLD | AUGUST 2020 draw on neural networks/big data and artifi- cial intelligence. Dr. Hill's Hill-RBF formula is perhaps the most notable, but there are others, for example the Ladas Super Formula 2.0 and the PEARL-DGS (Prediction Enhanced by Artificial Intelligence and Output Linearization) formula. In addition, the Precision Ladas Uni- versal Super algorithm applies "advanced AI to any static formula" Uday Devgan, MD, explains on his website The Hill-RBF formula, Dr. Hill explained, was developed with 44 investigators in 22 coun- tries, including mathematicians and engineers at MathWorks in the U.S. He said that 13 different parameters were initially evaluated. Using a ge- netic algorithm for version 1, they determined the AL, Ks, ACD, and postop spherical equiv- alent were the most important items of those evaluated. "As the size of the artificial intelligence model fitting dataset is increased, by the time of version 3 of the Hill-RBF method, we were able "Combined with an appropriate artificial intelligence model, big data allows for the calculation process to be greatly expanded in terms of its breadth and depth," Dr. Hill said. "For example, many current methods mostly limit possibilities to situations that are already understood, and manual optimization methods significantly limit the number of solution op- tions. Artificial intelligence is well-suited to real world problems for which ideal models are not available. This approach also has enhanced sen- sitivity for identifying and unraveling complex, non-linear relationships and is free of calcu- lation bias. If based on a high-quality dataset, IOL power selection by artificial intelligence has the potential to take IOL power selection to the next level."
