What is Lens Replacement?

Lens Replacement Surgery, also known as Lens Exchange (LE), Clear Lens Exchange (CLE), Natural Lens Replacement or Refractive Lens Exchange (RLE), is a transformative procedure aimed at correcting various vision issues. Similar to cataract surgery, Lens Replacement involves the removal of the eye’s natural crystalline lens and its replacement with an intraocular lens (IOL). This surgical innovation is particularly beneficial for individuals struggling with presbyopia, a condition that impairs near vision, as well as those requiring correction for both near and distance vision, or astigmatisms.

At Precision Vision London, our Lens Replacement Surgery is a bespoke solution, with the choice of intraocular lens tailored to each patient’s unique needs. This quick and safe procedure, takes less than 20 minutes per eye, and both eyes will be treated on the same day with the promise of a glasses-free life. Endorsed by the World Health Organization (WHO) as one of the safest medical treatments globally, Lens Replacement at Precision Vision is a proven pathway to visual freedom and clarity.

What is Lens Replacement?

Welcome to Precision Vision London, your gateway to a glasses-free future through advanced Lens Replacement surgery! If you’ve ever found yourself squinting at menus or struggling with reading glasses, envision bidding farewell to these hassles for good.

Lens Replacement is a revolutionary procedure designed to liberate you from the constraints of glasses and contact lenses. By replacing your eye’s natural crystalline lens with a state-of-the-art intraocular lens (IOL), we can effectively correct your vision and eliminate the need for external aids.

If your vision requires correction for both close-up tasks like reading and distance viewing, traditional laser eye surgery may fall short. In such cases, Lens Exchange emerges as the ideal solution, providing comprehensive correction for all fields of vision. An additional perk is the prevention of future cataracts, ensuring clarity and visual freedom for the rest of your life.

The Lens Replacement procedure mirrors the widely performed and trusted cataract surgery, endorsed by the World Health Organisation (WHO) as one of the safest medical procedures globally. Instead of addressing a cloudy lens (cataract), we replace a clear lens with an IOL tailored to correct your specific prescription. This transformative process is aptly named Clear Lens Exchange or Lens Replacement.

Embark on a journey toward perfect vision and freedom from glasses with Precision Vision London. Our Lens Replacement surgery not only guarantees full correction of your vision but also shields you from future cataracts. Say goodbye to the inconvenience of glasses and embrace a lifetime of clear, unaided vision.

Experience the Precision Vision London difference – where clarity meets precision, and a glasses-free life awaits you!

Suitability for Lens Replacement


As we age, the natural lens in our eye gradually weakens, causing difficulty focusing on objects up close and problems reading, eventually leading to the need for reading glasses after the age of 40. This is called presbyopia, and everyone develops it at some point. For this reason, Lens Replacement surgery is ideally suited for patients over the age of 40 who are already having reading problems.

To be eligible for lens replacement surgery, you must:

Must be over the age of 40
Have developed presbyopia (a reading prescription)
Any prescription range
Healthy eyes, which must lack any significant eye disease like glaucoma
Good general health
Lack of any existing eye infections
Not be allergic to anaesthetic


Although we are passionate about correcting the sight of all those we possibly can, Precision Vision neither provides experimental treatments nor operate on those who suffer from conditions that prevent safe and ethical treatment.

Common reasons patients are found unsuitable for treatment include:

Under the age of 40
Unusually large pupils
Specific medication
Certain health conditions: this includes autoimmune disease
Certain occupations involving the need for critical night vision (eg. HGV drivers, commercial pilots, etc) if wanting Trifocal lenses
Pregnancy or breastfeeding
Previous instance of serious eye trauma or retinal detachment

With the best surgical team in the UK, our combined expertise in non-laser treatments is without precedent. We take great pride in having the skills to help even those who have been turned down by other clinics.

About Intraocular Lens Implants (IOLs)

Welcome to Precision Vision – Your Leading Specialist in Intraocular Lens Implants

At Precision Vision, we elevate beyond the standard offerings of NHS providers. While basic Monofocal lenses are common elsewhere, our commitment to delivering truly tailored treatments sets us apart. We focus on customizing intraocular lens (IOL) implants based on your unique needs, determined through an in-depth consultation with our experienced surgeons.

Unlike traditional multifocal IOLs that initially promised improvements in distance and near vision, our clinic recognizes the evolving demands on intermediate vision in today’s digital age. Introducing Trifocal IOLs, the latest generation of multifocal lenses that redefine vision correction.

Trifocal IOLs provide a comprehensive solution, correcting distance, near, and crucially, intermediate vision. This innovation ensures you can perform daily tasks, including computer work, without the need for glasses. Unlike varifocal glasses or multifocal contact lenses, adapting to Trifocal IOLs is seamless and natural.

The cutting-edge technology behind Trifocal IOLs ensures efficient light transmittance through the lens implant, leading to improved intermediate vision with minimal glare and halos, especially noticeable at night. Published reports emphasize elevated levels of patient satisfaction, superior vision quality (especially during nighttime), and reduced dependence on glasses. Imagine a life with clear vision at all distances!

Precision Vision exclusively embraces these revolutionary Trifocal lenses. As an independent clinic with no ties to specific lens manufacturers, we have the flexibility to correct a wide range of prescriptions. Our reputation is founded on successfully treating patients considered unsuitable by other clinics.

Beyond the immediate benefits of vision correction, our Lens Replacement procedure also guards against future cataract development. This means you can enjoy a glasses-free life with the assurance that your vision is optimized for the long term.

Experience the Precision Vision difference in Intraocular Lens Implants – where personalised care and advanced technology converge for your visual well-being.

Types of Intraocular Lens Implants (IOLs)

We offer different types of IOLs, which can give you clear vision at different distances:

Monofocal: Available in both spherical and toric (for astigmatism) designs, this is single focus intraocular lens (IOL) which gives clear distance vision, and glasses are needed for reading and computer use.
Trifocal: Available in both spherical and toric (for astigmatism) designs, these lenses are able to correct more than one field of vision by using layered concentric circles, enabling for simultaneous correction of near, distance and intermediate vision leaving patients largely glasses free.

Lenses available at Precision Vision

Precision Vision is a completely independent surgeon led clinic and have no affiliation with any manufacturers or paid consultants enabling us to choose the best lenses to fit our patients’ visual and lifestyle needs. We have access to the three most widely used Trifocal (intraocular lenses) IOLs:

AT LISA (Carl Zeiss Meditec, Jena, Germany) – available in spherical and toric designs.
FineVision (PhysIOL, Liege, Belgium) – available in spherical and toric designs.
PanOptix (Alcon, Fort Worth, Texas) – available in spherical and toric designs.


Version Image Guided System Centurion Vision System The Lux-OR Ophthalmic Microscope

The VERION Image Guided System

This is used to capture a digital reference image of the eye during the initial assessment which is used to create a surgical plan. This equipment is also used throughout the treatment allowing the surgeon to see all incisions and alignments in real time, improving accuracy and minimising errors especially whilst correcting astigmatism.

VERION Image Guided System

The Centurion Vision System

Precision Vision is the first clinic in the UK to possess this equipment and it is the newest phacoemulsification system available (this breaks up and removes the natural lens). It allows for smaller incisions and is able to optimise every phase of the lens removal. The device also controls the intra-ocular pressure throughout the treatment and enhances the control of the surgeon, consequently improving the patient’s outcome and accelerating the recovery process.

Centurion Vision System

The Lux-OR Ophthalmic Microscope

The Lux-OR LX3 with Q-VUE Ophthalmic Microscope is designed to provide superior visualisation throughout the surgical procedure, this microscope is able to expand the visual field with a highly stable, 6x greater red reflex zone, providing excellent visual detail with superior visualisation of the retina.

Lens Replacement vs Presbyond

Presbyond is a laser treatment or Blended vision where one eye is ‘set’ for distance vision and the other eye is ‘set’ for near vision. It can provide a satisfactory balance between distance and near vision for a select category of patients, however, this group is limited and generally restricted to low, non-complex prescriptions and those who can adapt and tolerate a discrepancy between the two eyes. An alternative to this laser treatment is a Lens Replacement with a Trifocal lens, below is a comparison table between the two.

  Lens Replacement Trifocal Presbyond/Blended vision
Vision Both eyes given distance, intermediate and near vision – no compromise in vision or binocularity Difference between eyes can lead to imbalance and compromise of vision
Effects Permanent as natural lens replaced, life-long solution Temporary as eyes still continue to age
Need for retreatment No retreatment needed as maximum reading vision given Retreatment or fine tuning needed after approx 5 years
Future cost One time cost – no vision changes Extra cost for retreatment or fine tuning once eyesight changes
Suitability 99% suitable over a certain age Not suited to everyone, must be able tolerate difference between two eyes
Cataract development No cataract development as natural lens replaced with permanent implant Cataract surgery most likely in future
Prescription Range No limit – tailor made lenses can treat all prescriptions Limited – can only treat simple, low prescriptions

Lens Replacement FAQ's

Who is suitable for Lens Replacement surgery?

Lens Replacement treatment is suitable for those over the age of 40 whose natural lens has started to age and will naturally deteriorate over time. There is no upper age limit and no prescription limitation. The only requirement is that your prescription has stabilised and that it is not currently in the midst of a decline.

Lens Replacement is suitable for patients who have very high and complicated prescriptions that cannot be treated by Laser Eye Surgery or Implantable Contact Lens treatment.

What is the difference between Lens Replacement and cataract surgery?

The Lens Replacement procedure is virtually identical to cataract surgery. The only difference is that a clear lens is removed in the Lens Replacement treatment and a cloudy lens is removed in cataract surgery.

What are Monofocal implants?

Traditional intra-ocular implants are Monofocal lenses which focus light to only one point, meaning they correct distance vision only and glasses will be needed for near vision. This is the type of lens that is typically used by the NHS.

What are Trifocal implants?

A Trifocal intraocular lens has more than one point of focus, enabling clear distance, intermediate and near vision. It has revolutionised the results of treatment and allows for patients to be glasses free.

Are Trifocal lenses like varifocal spectacles or contact lenses?

The optical design of intraocular lenses is completely different to varifocal spectacles. Instead of a patient needing to move their head to adjust the focus, they will be able to comfortably see distance, intermediate and near without having to make any movements. Layered concentric circles are used to correct each form of prescription issue allowing for simultaneous correction of all fields of vision.

What lenses do Precision Vision provide?

Precision Vision provide lenses from the following companies:

What if you are unsuitable for a Trifocal lenses?

Suitability for treatment and the type of lens is determined at your consultation.

If you are unsuitable for Trifocal intraocular lenses, Monofocal lenses are available. These can be used to either aim for monovision (one eye for distance, one eye for reading), or to correct your distance vision in both eyes and glasses will be needed for near vision. This will all be explained in detail during your consultation

How long does the lens implant last?

Once the natural lens has been removed and replaced with lens implants patients will likely never require surgery again. The materials from which the lenses are made from have been subject to accelerated ageing tests. Results have demonstrated that the lens material will last in excess of 150 years before showing signs of degradation.

Will the procedure be painful?

No pain is felt as anaesthetic drops are used to numb the eye. However some discomfort or pressure can be felt during the procedure.

How long after surgery will you be able to see clearly?

Most patients notice a difference to their vision immediately after the procedure. Distance vision is the first field of vision to settle, typically taking 24 to 48 hours. However, it can take slightly longer to adjust to the new reading vision.

How much time off work will you require?

Generally you will need 3-5 days off work (for most office jobs). Two for the treatment and one or two days afterwards to rest. Patients are able to perform most day to day tasks one day after surgery without any difficulty. Your working environment will also be taken into consideration and our surgeon will advise on what precautions should be taken at your consultation.

Will there be restrictions after surgery?

There will be a few restrictions after treatment. Examples include avoiding sports that may cause trauma to the eye, avoiding dusty environments and lifting heavy weights. At your consultation, we will take into consideration your lifestyle and hobbies and advise you accordingly.

Where will the treatment take place?

All our treatments are carried out at our Precision Vision clinic on 22 A, Harely Street London W1 9PB. Precision Vision is one of the very few clinics in the UK where everything from consultation to surgery and aftercare is conducted under one roof.

Can you develop cataracts in the future?

The Refractive Lens Exchange procedure involves removing the natural lens where a cataract would have developed. When a patient undergoes Lens Replacement treatment, it means that they will never develop a cataract in either eye at any point in the future.

Will you be able to feel the implant?

The lens implant is inside the eye where there are no nerves or sensation, so it cannot be felt. It will not feel like a contact lens and you will be completely unaware that it is there, apart from experiencing greatly improved vision.

How many times will you need to attend the Harley Street clinic?

Your consultation, treatment, one day post op, two week and the six week aftercare appointments are carried out at Precision Vision’s Harley Street clinic. After this time, we can hand you over to the care of one of our nationwide independent optometrist partners, allowing you to stay closer to home for the remainder of the follow-up appointments.
