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 ...

New Objective Refraction Metric Based on Sphere Fitting to the Wavefront
Journal of Ophthalmology, 2017 Purpose. To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil ...

Convergence insufficiency prevalence in attention deficit and hyperactivity disorder children depends on the diagnosis criteria. [PDF]
Ophthalmic Physiol OptAbstract Purpose Attention deficit and hyperactivity disorder (ADHD) is a neurodevelopmental condition commonly seen in children and adolescents, characterised by an increase in distractibility or inattention. Several studies have noted a higher rate of visual problems in this group, especially convergence insufficiency (CI), but when using different ...

Subjective quasi-vector-based refraction with a conventional phoropter. [PDF]
Ophthalmic Physiol OptAbstract Purpose To introduce a novel methodology for subjective refraction based on power vectors with a conventional phoropter. Methods A conventional phoropter was used to measure power vector components of refraction (M, J0 and J45) directly by using the sphere power (for M measurement) and the cylinder power combined with the Jackson cross ...
