Facts to source and verify
Trifocal IOLs split light into three focal points for distance, intermediate and near; EDOF lenses stretch the range of focus from distance to intermediate with less light splitting; trifocals generally give better unaided reading while EDOF lenses usually cause fewer halos; macular disease, advanced glaucoma or significant irregular astigmatism can make diffractive lenses unsuitable; most patients adapt to halos over weeks to months (neuroadaptation)
