Cataracts often cause glare, this being the primary reason to have them removed.
Iols (replacement lenses) implanted at cataract surgery
should clear the vision
, but swelling of the cornea (window) afterwards and other defects can also create glare. If a multifocal iol is implanted, expect glare until you get used to them! from your question, i can't tell where you fit in this picture!
