Several studies report partial or complete resolution of symptoms after YAG laser anterior capsulotomy of the nasal portion of the anterior capsule. 23,24 This evidence disagrees with an earlier study’s hypothesis that eventual opacification and translucency of the anterior capsule helps reduce shadow perception by scattering light into that region …Lights and Shadows.
