Glasses – Why do I need glasses after cataract surgery?

When you have cataract surgery, your eye’s natural lens is replaced with an intraocular lens (IOL). If your cataract surgery is carried out on the NHS(1), then you’ll only have the option of a monofocal lens, which will correct astigmatism, enabling you to see without glasses at one distance only(1).

You’ll be able to choose to have an IOL to correct either near or far-sightedness. If, however, you’re having your cataract surgery done privately, then you’ll be able to choose from monofocal, varifocal and toric lenses; toric lenses are to correct astigmatism and can be either monofocal or varifocal.

So, if you get a monofocal IOL, and had previously had issues with both near and far sight, then you’ll still need glasses following your cataract surgery, to correct the one that isn’t corrected with your intraocular lens.
