Glasses – Why do I need glasses after cataract surgery?

After cataract surgery, you may still need glasses because a standard NHS monofocal intraocular lens (IOL) can only correct vision for either near or distance, not both. If you had both long- and short-sightedness before surgery, glasses are usually still required, though your prescription may change due to improved vision. Private cataract surgery offers more lens options, including multifocal and toric lenses, which can correct astigmatism and reduce the need for glasses.
