Everything you need to know

Lens options

During cataract surgery, the eyes’ natural lens must be removed and replaced with an artificial lens. There are several lens options available – from simple like-for-like lens replacement to an upgraded lens that will mean you no longer have to wear glasses. Lens choice is an important decision. 

Everything you need to know

Lens options

Depending on your needs, there are a number of lens options available – from simple like-for-like lens replacement to an upgraded lens that will mean you no longer have to wear glasses. Speak to your surgeon at your consultation to discuss which lens is best for you.

Monofocal lens cataract surgery

A monofocal lens will give you good vision at one distance but you will need to wear contact lenses or glasses for other distances. Most people choose to restore their distance vision and wear glasses for close up tasks such as reading. 

It is important to remember that you do not retain the vision you had pre-surgery. If your close vision was perfect before cataracts but you opt for a lens that gives you good distance vision, you will not retain the perfect close vision you had. Your new lens effectively resets your vision. This lens is a good choice for people who don’t mind wearing glasses. 

Trifocal lens cataract surgery

As well as removing your cataracts we can also improve your vision and reduce your reliance on glasses. For trifocal / multifocal cataract surgery your eyes must be in good health, with no sign of macular degeneration or glaucoma.

If you have needed glasses your whole life and you select trifocal lenses, your will most likely be glasses-free after surgery. These lenses are a great choice if you really don’t enjoy wearing glasses or are intolerant to contact lenses.

Toric lens cataract surgery

This option can help correct astigmatism.You can select a combination of toric lenses with either monofocal lenses or trifocal lenses.

Lens options

The lens simulator allows you to see how your vision will be affected by the various lens options available to you. From the top tabs, select the description that best matches your prescription. The image below will represent your own vision (For example, you will see that when you select ‘short sighted’ from the top tabs, the ‘pre-surgery’ image will show that the objects in the fore ground are focused but those in the distance are blurry). You can then select the various lens options so understand how your vision will be affected post cataract surgery.
