About 1% cannot adapt and swap to a monofocal lens. In the FDA study of the PanOptix trifocal lens, 99.2% of patients (126 of 127) would choose the same lens again, against 87.4% with a monofocal; fewer than 5% were &#8220;bothered very much&#8221; by halos, starbursts or glare at six months. A 2019 analysis of nine studies found EDOF lenses give excellent distance and intermediate vision but moderate near vision.<\/p>\n<h3 data-reveal>Will I need glasses after cataract surgery?<\/h3>\n<p data-reveal>Possibly. The NHS says you may still need glasses for reading or distance, and your prescription may change. With a monofocal lens, expect reading glasses; with a multifocal lens, any glasses are usually for one specific task.<\/p><\/div>\t<\/div><\/div><\/div><\/section>\n<!-- Table (Table on a tinted panel) End -->\n\n\n<!-- Image + Text (Image left, text right) Start -->\n<section class=\"psec pad split-sec\" id=\"which-lens-is-best-for-night-driving\"><div class=\"container-fluid px-0\"><div class=\"row g-0\"><div class=\"col-12\"><div class=\"split\"><div class=\"row\">\n\t\t<div class=\"split-media col-12 col-lg-6\" data-reveal><div class=\"media\" data-parallax><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"800\" src=\"https:\/\/laseristanbulclinic.com\/wp-content\/uploads\/2026\/10\/intraocular-lens-implant-819x1024.webp\" class=\"attachment-large size-large\" alt=\"Intraocular lens implant\" sizes=\"auto, (max-width: 991px) 100vw, 50vw\" srcset=\"https:\/\/laseristanbulclinic.com\/wp-content\/uploads\/2026\/10\/intraocular-lens-implant-819x1024.webp 819w, https:\/\/laseristanbulclinic.com\/wp-content\/uploads\/2026\/10\/intraocular-lens-implant-240x300.webp 240w, https:\/\/laseristanbulclinic.com\/wp-content\/uploads\/2026\/10\/intraocular-lens-implant-768x960.webp 768w, https:\/\/laseristanbulclinic.com\/wp-content\/uploads\/2026\/10\/intraocular-lens-implant.webp 1200w\" \/><\/div><\/div>\n\t\t<div class=\"split-copy col-12 col-lg-6\">\n\t\t\t\t\t\t<h2 class=\"t48\" data-reveal>Which lens is best for night driving?<\/h2>\n\t\t\t\t\t\t<p class=\"t22 lede\" data-reveal>A monofocal lens usually causes the fewest night-time side effects.
