Lens Opacities Classification System III-Based Computational Model of Nuclear Cataracts

Abstract

This study developed a computational model to assess the optical properties of nuclear cataracts, using slit-lamp lens images for clinical evaluation based on color and opacity. Cataracts were represented as spherical particles distinct from the surrounding lens medium, with diameters ranging from tens to hundreds of nanometers. This study examined the effects of particle diameter, concentration, and colorimetric properties on the opacity of cataracts and their relationship with images on the retina. The findings indicate that particle size and concentration influence opacity. To ensure alignment with the Lens Opacities Classification System III, colors were defined based on a color absorption coefficient limited within a predetermined range. The developed model was used to simulate the yellow-tinted vision experienced by patients with nuclear cataracts.
