Multi-Focal Intraocular Lens


Multi-Focal Intraocular Lenses are available at the following centres:

Nuffield Health Guildford Hospital
Manchester Royal Eye Hospital
Sheffield Royal Hallamshire Hospital


Multi-focal intraocular lenses have special features that give you good near, intermediate and distance vision-all in one lens.

Multifocal intraocular lenses give you a good chance of living glasses-free for the majority of your activities after cataract surgery. A multifocal IOL  can have many designs varying from bifocal lens to one that resembles a bulls-eye target, with concentric circles for near, intermediate and distance vision. Your brain automatically zeros in on the range of vision you need-so you can see objects well at all distances.

Multifocal intraocular lenses are an excellent choice if you:

  • Want to reduce your dependence on glasses or contacts as much as possible.
  • Do not have astigmatism or are willing to address your astigmatism by wearing corrective lenses or by having additional surgeries such as LASIK or limbal relaxing incisions.
  • Are less comfortable adapting to change and learning new skills.
  • Are willing to risk some minor night vision symptoms.

If you wish to reduce your dependence on glasses or contacts but multifocal lenses don’t seem like a good match for your needs, consider accommodative intraocular lenses or monovision.

A good way to reduce your dependence on glasses

Multifocal IOLs have a very high success rate and give you a good chance of not needing glasses after cataract surgery. A large majority of patients report enough eyesight improvement that they either never or only occasionally need to wear glasses after surgery. As with all surgery, patients with additional health conditions should ask their doctor what they can reasonably expect in their specific case.

When you may need glasses

It may take several weeks to several months for you to reach your best eyesight improvement. And it is usually recommended to have cataract surgery on both eyes within a few weeks time, so the brain does not need to adjust to unbalanced vision while only one eye has a corrected lens.

There is a chance you may need glasses for some tasks even after you adjust. For example, some patients need glasses to:

  • Read fine print
  • See more clearly in low light conditions
  • Obtain the best vision at intermediate distances, like at the computer
Possible night vision symptoms

As your brain adjusts to the new visual information from the multifocal IOL, you may notice some rings around lights at night, which usually get better in time and diminish within six months or so. Most patients say these symptoms are not noticeable or bothersome and rarely affect their day or night activities. A small number of patients have night vision symptoms on an ongoing basis. Even when this occurs, these symptoms rarely affect tasks such as night driving.However, in rare instances, multifocal IOLs may make night driving more challenging than with standard or accommodative IOLs.
