Optical and Clinical Outcomes of an Isofocal Intraocular Lens vs. a Monofocal Standard Lens [PDF]
Life, 2023 The aim of this study is to evaluate the results obtained on the optical bench and clinically with an isofocal lens (ISOPure, BVI medical, Belgium) to compare them to a standard monofocal one (MicroPure, BVI medical, Belgium).

Fast and accurate visual acuity prediction based on optical aberrations and machine learning [PDF]
Scientific ReportsIn this work, we propose three machine learning-based methods for predicting visual acuity (VA). Two methods utilize regression trees (LSBoost and XGBoost), and the third employs a neural network that classifies simulated aberrated optotypes as ...
