Your Choice of Intraocular Lens (IOL)

There are a number of different intraocular lenses (IOLs) that can be implanted during cataract surgery depending on your vision requirements, and I will discuss them in full during your consultation.

Your Choice of Intraocular Lens (IOL)

There are a number of different intraocular lenses (IOLs) that can be implanted during cataract surgery depending on your vision requirements, and I will discuss them in full during your consultation.

Monofocal IOLs

The monofocal or standard IOL is the most commonly implanted lens and if you’re undergoing cataract surgery on the NHS, you will usually be offered this option.

A monofocal lens will only offer one fixed focus, whether that’s far, intermediate or near, although it’s usually used to achieve good distance vision. You will then likely need to wear glasses for reading or close work.

Multifocal IOLs

Multifocal IOLs are a more recent development in lens replacement and are specially designed to achieve good near, intermediate or distance vision all in one. They use different optical strengths across different areas of the lens.

These can be a good option if you wish to reduce your dependence on glasses or contact lenses.

However, they can cause some night vision issues (glare and haloes) and aren’t suitable for all patients.

EDOF IOLs

Extended depth of focus (EDOF) IOLs can be a good choice in patients who want to reduce their dependence on glasses for distance and intermediate vision. You will still need to wear glasses for reading but they have the advantage of night vision issues (glare and haloes) compared to multifocal IOLs.

Toric IOLs

These are specially designed lenses that are suitable for patients with significant astigmatism. This is caused by the irregular shape of the cornea, and sufferers typically experience some degree of blurred vision at all distances. Toric IOLs have been proven to reduce dependence on glasses.

Aspheric IOLs

These are premium IOLs that follow the spherical shape of the eye’s natural lens. They can provide better overall vision, including sharper contrast and are better for low light conditions, such as driving at night.
