Cataract Lenses: Types of IntraOcular Lens (IOL) Implant

An (IOL) Intraocular lens is an artificial lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems.

Always work with your doctor to select the right intraocular lens for your condition and preferred outcome. 

What does your vision look like with a cataract?

Vision with cataract is foggy and dull. With time, vision gets worse as the cataract gets more dense.

Cataract Lenses - Monofocal Lens View

Monofocal lens

A monofocal lens has a single point of clear focus. This provides distance vision only. Glasses are needed for middle and near vision.

Clear vision in the distance, with middle and near range being blurred and needing glasses to see clearly.

Some patients that have always been near-sighted may opt for near vision without glasses, and accept that all other distances will be blurred and require glasses to see clearly.

Cataract Lenses: Increased Range Of Focus

Increased range of focus (IROF) lens

Clear vision for distance and middle, with reasonable near. But glasses are needed to optimise near vision and for reading.

Cataract Lenses: Multifocal IOL

Multifocal lens

Clear vision for distance, middle, and reading. Multifocal lenses work best in good lighting, with standard print size and with good contrast print (such as black on white).

Astigmatism that is not corrected with a toric lens

Astigmatism is an asymmetry in the shape of the cornea (like a rugby ball instead of a football). It causes blurred vision which can be corrected with glasses, or by using a toric lens implant. A toric lens implant means clearer vision without glasses after surgery.
Each of the lens implant types described above comes in a toric version to treat astigmatism, as well as providing the benefits previously described.

Astigmatism that is not corrected with a toric lens
Vision remains blurred at all distances and requires glasses to achieve clear sight. The more the amount of astigmatism, the more blurred the vision.

Cataract Lenses: Multifocal IOL

Astigmatism that is corrected with a toric lens

A toric IOL has marks to indicated the location on the lens where the astigmatism is corrected. This allows the surgeons to align the toric IOL with the astigmatism on the patient’s cornea.

Who might need our treatment?

You’re over 45 and would love to read again without glasses

Unfortunately, reading glasses or varifocals get in the way of many of the things you most enjoy. Yes, spectacles help, but they are annoying little appendages that you lose or must clean to see clearly.

Book a consultation

Your vision is yellowing, duller, and cataracts are forming.

The effect on your life can vary from being slightly frustrating, through to significantly affecting your ability to function independently, or even causing a devastating reduction in vision.

Before you developed cataracts, you were living a full life. You may enjoy the outdoors, have indoor hobbies or enjoy travelling. Or, perhaps you have finished working and are now taking the time to enjoy everything you may have missed when you were busy making a living.

Sadly, your eyes now dull the shine of life’s beautiful landscape. The trees, the flowers and even the sky don’t seem as bright as they used to look.

Get your life back without the compromise.

Hear from our patients

With over 6300+ surgeries performed hear from just a few of my happy patients.

It’s been incredibly liberating to wake up in the morning and be able to see without reaching for my glasses.

Cataract Surgery

I can go any anywhere and see anything near and far. I can see now as well as I could when I was 18 years of age which is incredible and I’m looking forward to clear vision for the rest of my life.

Kevin Taylor
Cataract Surgery

“No. 1 – My advice would be do it. No. 2 – See Mohammed if you can. I made the decision to not go down the NHS route because I wanted to see the best consultant – probably in the UK… It was absolutely worth it… because you can’t really put a price on your sight.”

Martin Harris
Cataract Surgery & Keratoconus Treatment

“I don’t wear glasses at all now. I don’t need them. I was impressed by his professionalism, his calmness. He explained everything clearly and in layman’s language… I would say to anyone considering treatment: just do it. Don’t be afraid of it. It’s painless and it works.”

Martin Power
Refractive Cataract Surgery with multifocal toric lenses

“I can’t speak highly enough of (Prof Muhtaseb). Nothing was too much trouble, you could phone anytime, day or night. I wish I had done it when I first started wearing reading glasses and just gone to Prof Muhtaseb then and got it done. I would do it all over again, but do it much faster.”

Ann Edworthy
Refractive Cataract Surgery & Piggyback Lenses

“I would definitely recommend the professor. I think his approach is perfect! If you have any anxieties at all – just check with someone who’s had the procedure done. I had no pain at all. I expected a little bit of discomfort – but no pain, that was good. It’s life-enhancing and that’s not something you can put clearly enough. I didn’t realise how green the trees were! It’s lovely!”
