Eye Lens Replacement Surgery for Vision Correction

Lens replacement – Give your eyes an upgrade

What is lens replacement surgery

Lens replacement surgery, also called refractive lens exchange (RLE), offers a permanent vision correction solution.

This outpatient procedure treats problems like presbyopia (near vision loss), cataracts (cloudy lenses), and extreme farsightedness or nearsightedness/ These include conditions that are unsuitable for laser surgery.

Lens replacement surgery boasts a high success rate, giving you a clear view of the world and a life less reliant on glasses or contacts.

How lens replacement works

Think of lens replacement surgery as an upgrade for your natural lens.

During this procedure, your eye’s lens is gently removed and replaced with a customised, clear artificial lens. This is similar to cataract surgery, but performed proactively before cataracts develop.

The real magic happens with the lens implant itself. There are different types available, each chosen based on your specific needs and a thorough pre-operative exam.

Multifocal Implants – See Clearly at All Distances

Multifocal implants – also called Multifocal IOLs (mIOLs) – are a game-changer. This innovative, new technology mimics your eye’s natural ability to focus, offering clear vision for near, intermediate, and far distances. So with multifocal implants, you’ll see the object you want to focus on clearly, without needing glasses or contacts.

Results You Can See

Eye lens replacement surgery is an outpatient procedure, boasting both high safety and patient satisfaction.

Surgical risks are minimal, and Prof Mohammed Muhtaseb will discuss them thoroughly during your initial consultation.

Here’s the good news: the vast majority of iLase patients experience exceptional results after lens replacement surgery, with significant improvement to both vision and quality of life.

Key benefits of lens replacement

Lens replacement surgery is about more than correcting vision – it’s about embracing a new chapter in your life.

Upgrade your eyes

This 15 minute procedure offers you the the freedom to see clearly, near and far without the need for glasses or contacts.

Improve vision quality

Sharper, clearer and more convenient vision compared to what you might be experiencing with glasses or contacts.

Address presbyopia

This age-related loss of near vision affecting people over the age of 40, is caused by the natural aging of the lens. It cannot be tackled by laser vision correction surgery, which focuses on reshaping the cornea.

Prevent cataracts

Since this procedure replaces your natural lens, it eliminates the possibility of future cataracts developing, a condition requiring separate surgery.

Long-term stability

Unlike laser eye surgery that might require enhancements over time, lens replacement offers a more stable and long-term vision correction solution.

Renewed quality of life

Enjoy a new level of confidence with sharp, unaided vision that allows you to participate fully in life’s activities, like exercise, travel, and hobbies.

Lens replacement FAQs

How will I know if I’m suitable for lens replacement surgery?

You could be suitable for lens replacement if you:

  • Are 50 years or over (although exceptions to this may be considered depending on individual circumstances).
  • Have a spectacle prescription for distance or near vision, or both.
  • Wish to become less reliant on their glasses or contact lenses.
  • Want to be free from glasses and contact lenses.

What is the process for getting a diagnosis for lens replacement treatment at iLase?

Step 1: The first step towards achieving freedom from glasses with lens replacement is to arrange a consultation with us. You do not need a referral, but it is always helpful if you can bring the report from your latest optician’s eye test.

Step 2: After a thorough consultation and examination, we may ask you to have further tests if we think it’s necessary.

Step 3: Once we have agreed to a personalised treatment plan for you, we will offer you a range of dates for the surgery and plan your post-operative care in line with your specific circumstances.

Step 4: When you arrive in the surgical centre, you will be greeted by the team. The day will go very smoothly and you will leave the hospital having received the very best care and attention throughout your time with us.

Which is better, lens replacement or laser vision correction?

It’s not a question of which is “better”, but which is most suitable for your specific needs and circumstances. Here’s a breakdown to help you choose:

Good candidates for lens replacement

  • Over 40 and experiencing presbyopia: lens replacement with multifocal implants can address both near and far vision.
  • Have severe refractive errors: laser correction might not be suitable for very high nearsightedness, farsightedness, or astigmatism.
  • Have existing corneal conditions: Conditions like keratoconus can disqualify you from laser correction making lens replacement a viable alternative.
  • Want to prevent future cataracts: lens replacement, as the name suggests, replaces your natural lens, eliminating the possibility of cataracts developing.

Good candidates for laser correction

  • Aged 18-40 with good overall health: Age is a factor, and laser correction might not be suitable for developing eyes.
  • Have mild to moderate refractive errors: laser correction works best for addressing these levels.
  • Have a healthy cornea: The procedure relies on reshaping the cornea, so its health is crucial.
  • Prefer a less invasive procedure: laser correction is typically faster than lens replacement.
What are the lens replacement surgery risks?

Lens replacement is a very safe procedure.

Like all types of surgery, lens replacement carries some risk of unexpected events occurring either during or after the operation. These risks are usually 1% or less, and the vast majority of patients are very happy with the results of their surgery.

Will I need glasses after lens replacement?

The variety of intraocular lenses (IOL) that can be used for this procedure enable us to deliver a tailored approach to visual correction.

Here is a breakdown of different IOL types:


You will see in the distance but uses glasses for middle and near.

Enhanced Monofocal

You will see in the distance and have some functional middle distance vision, but will require glasses for finer middle distance vision and for near.

Multifocal / Trifocal

You will see clearly in the distance, middle and near.

Multifocal – Extended Depth Of Focus (EDOF)

Lenses that combine multifocal and EDOF technology add to the range of multifocal lens options.

The visual outcomes detailed above are target outcomes, not guarantees. There is a possibility that glasses may still be required to achieve best vision, whatever the type of IOL that is used.

What is the success rate of lens replacement?

Lens replacement surgery boasts a very high success rate, with 95% of patients achieving vision of driving standard or better following the procedure.

Is lens replacement surgery painful?

Lens replacement is not a painful procedure. With local anaesthesia and a focus on patient comfort, most patients experience minimal discomfort during and after the surgery.

If you’re concerned about any aspect of the procedure, discuss it with Prof Mohammed Muhtaseb, who can address your specific anxieties and explain what to expect in terms of comfort.

Is lens replacement the same as cataract surgery?

Both procedures use similar techniques and offer excellent success rates, but they address different situations:

Lens replacement (RLE): This is an elective surgery for people with good vision who want to improve it further, especially by correcting presbyopia (age-related nearsightedness). During RLE, your natural lens, even if clear, is replaced with an artificial intraocular lens (IOL).

Cataract surgery: This is a necessary surgery for people who have developed cataracts. Cataracts are a clouding of the natural lens in your eye, which significantly affects vision. Cataract surgery removes the clouded natural lens and replaces it with a clear artificial IOL to restore vision.

Why is my vision blurred after lens replacement surgery?

Blurry vision after lens replacement is normal. Your eye is healing, adjusting to a new lens, and might have some inflammation. It usually clears within days. If blurry vision worsens, persists, or you have pain/redness, we ask that you contact the clinic for additional post-operative support.

How much does eye lens replacement surgery cost? 

iLase offers convenient payment options to suit your timescale and budget, with the cost of treatment from £3,286 per eye.

This all inclusive price covers:

  • Hospital fees
  • Anaesthetist fees
  • Lens implants**
  • Aftercare (as per T&Cs of surgery)

Prices may vary depending on the type of lens chosen for your surgery as well as for any other additional procedures. Payment plans may be available through the hospital where your surgery is conducted. Please contact us to discuss your options.

Your vision is yellowing, duller, and cataracts are forming. You feel like your eyes are letting you down

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. Experience what life used to look like. Even better, if you’ve worn glasses or contact lenses, discover the incredible once-in-a-lifetime opportunity that modern cataract surgery affords.


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.


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

“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

“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!”
