Why Choose Precision Vision London?
Precision Vision London is a surgeon-led private eye clinic on Harley Street — London’s most established private medical district. We perform Refractive Lens Exchange, cataract surgery, laser eye surgery, and implantable contact lens (ICL) procedures.
The best way to find out which treatment suits you is to book a consultation, where we’ll carry out advanced diagnostic scans and give you a clear recommendation.
What is Refractive Lens Exchange?
The lens inside your eye sits behind the pupil and focuses light onto the retina. With age, this natural crystalline lens becomes less flexible, eventually causing the reading difficulty known as presbyopia. It can also become cloudy, forming a cataract.
Refractive Lens Exchange replaces this natural lens with an artificial intraocular lens (IOL) — a custom-made implant that corrects your specific prescription. The procedure is also known as Clear Lens Exchange (CLE), Lens Exchange Surgery, Natural Lens Replacement, or Refractive Lens Replacement Surgery. All terms describe the same operation.
RLE is identical to cataract surgery in surgical technique. The only difference is the reason it is performed: cataract surgery removes a cloudy lens to restore vision, while RLE removes a clear lens to correct refractive error and reduce dependence on glasses.
Lens replacement is one of the most commonly performed surgical procedures worldwide. Data from the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) captured 330,202 cases from 16 countries in 2019 alone, with refractive lens exchange accounting for 46.6% of reported refractive surgery procedures.
Prescription Ranges We Treat
Refractive Lens Exchange is suitable for a wider range of prescriptions than laser surgery. At Precision Vision London, we regularly treat:
- Short-sightedness (myopia): up to approximately -30.00 dioptres
- Long-sightedness (hyperopia): up to approximately +15.00 dioptres
- Astigmatism: up to approximately 12.00 dioptres, corrected with toric IOLs
Prescriptions outside these ranges are assessed individually. We can often treat complex cases that high-volume chain clinics cannot take on. If your prescription falls outside these ranges, or you have been told you are unsuitable for vision correction elsewhere, a consultation is the only way to confirm what we can achieve for you.
Who is Suitable for Refractive Lens Exchange?
How We Determine Your Suitability
RLE is not suitable for everyone. Suitability is determined at your consultation based on your prescription, eye health, age, lifestyle, and occupation. Every patient at Precision Vision London receives a two-hour consultation before any treatment is recommended.
Only an in-person consultation with full diagnostics can confirm suitability. A phone assessment with our patient coordinators will establish whether a consultation is appropriate before any fees are charged.
You may be suitable if you:
- Are aged 40 or over and have developed presbyopia (difficulty focusing on near objects)
- Have a prescription outside the safe range for laser eye surgery (LASIK or PRK)
- Have thin corneas or corneal irregularities that rule out laser vision correction
- Want a permanent solution that also removes the possibility of future cataract surgery
- Are in good general health with no active eye infections or significant eye disease
You may not be suitable if you:
- Are under the age of 40
- Have unusually large pupils (increases risk of glare with multifocal lenses)
- Have certain autoimmune conditions
- Are pregnant or breastfeeding
- Have a history of serious eye trauma or retinal detachment
- Have significant eye disease such as advanced glaucoma or macular degeneration
- Require critical night vision for your occupation (for example, HGV drivers or commercial pilots) if considering multifocal lenses
Borderline cases we assess carefully
Some patients fall into a grey area where suitability depends on detailed assessment. We will review your case individually if you:
- Have had previous eye surgery, including laser vision correction
- Have controlled glaucoma or diabetes
- Have had retinal detachment treated in one eye
- Take medications that affect pupil size (for example, tamsulosin)
- Have early-stage macular changes
Told You're Unsuitable Elsewhere? Read This
Yes — in many cases. We frequently see patients who have been told at other clinics that they are not candidates for vision correction. Common reasons include:
- A prescription outside the safe range for LASIK, LASEK/transPRK, SMILE, or PRK
- Corneas too thin or irregular for laser surgery
- Early lens opacities that make laser results less predictable
- Previous laser eye surgery, where vision has since changed
- High astigmatism combined with other refractive errors
In many of these cases, RLE with a premium IOL produces a more stable and predictable outcome than laser surgery would have. Published research on RLE in modern practice (Alió et al.) supports this, particularly for patients with high degrees of hyperopia or presbyopia.
If you’ve been told you’re not suitable for vision correction elsewhere, a consultation at Precision Vision London is worth the second opinion. We will not recommend a procedure that isn’t right for you — but we have often been able to help patients who had been given up on.
“Many of the patients I see at Precision Vision London have been told elsewhere that they aren’t suitable for laser eye surgery — usually because their prescription is too high, or their corneas are too thin. For these patients, RLE with a trifocal lens often yields a better outcome than laser alone would have. Suitability is individual, which is why a thorough consultation matters.”
— Dr Radwan Almousa
The Refractive Lens Exchange Procedure — Step by Step
Each eye takes around 20 minutes
Refractive Lens Exchange is a day-case procedure performed under local anaesthetic. You will be awake but will not feel pain. Most patients describe the experience as comfortable and straightforward.
The procedure follows these stages for each eye:
- Anaesthetic drops numb the eye. A mild sedative may be given to help you relax.
- Dilating drops widen the pupil to allow access to the lens.
- A soft eyelid guard is placed to prevent blinking during surgery.
- A small self-sealing incision (approximately 2mm) is made at the edge of the cornea.
- The natural lens is gently broken up and aspirated using ultrasound energy, a technique known as phacoemulsification, the standard method recommended by the Royal College of Ophthalmologists for modern lens surgery. This is performed using the Centurion Vision System, which fragments the lens and removes it through a self-sealing micro incision.
- Your custom artificial lens is inserted and held in place by the back membrane of the lens capsule — the same structure that previously held your natural lens.
- The micro incision self-seals. No stitches are required.
Each eye takes around 20 minutes. At Precision Vision London, both eyes can usually be treated on the same day, depending on your suitability. The procedure is performed by Dr Almousa at our Harley Street clinic using the Alcon Refractive Suite.
Your first post-operative check takes place the day after surgery, led by Dr Pillai and our clinical team.
Your Intraocular Lens (IOL) Options
The choice of lens implant is the most important decision in the whole procedure. It determines what you will actually see after surgery — at what distances, with what clarity, and under what lighting conditions.
At Precision Vision London, we specialise in Trifocal IOLs. As an independent clinic with no manufacturer affiliations, we select lenses based solely on what suits each patient’s eye anatomy and lifestyle — not on commercial agreements with any lens maker.
Types of intraocular lens
| Lens type | Vision corrected | Typically suited to |
|---|---|---|
| Monofocal | Distance vision correction | Patients comfortable using reading glasses or with demanding night vision requirements |
| Monofocal Toric | Distance vision correction with astigmatism | As above, where astigmatism is present |
| Multifocal / Trifocal | Distance, reading and intermediate vision correction | Patients seeking full spectacle independence |
| Multifocal Toric | Distance, reading and intermediate vision correction with an astigmatism | As above, where astigmatism is present |
Monofocal & Monofocal Toric IOLs
Monofocal (spherical or toric): Best suited to patients who are comfortable continuing to use reading glasses, or who have occupational night vision demands where multifocal halos would be a problem — for example, HGV drivers or commercial pilots. Also a sensible choice for patients with early macular changes or other retinal conditions where multifocal lenses would compromise image quality.
Multifocal & Trifocal IOLs
Multifocal / Trifocal (spherical or toric): Our default recommendation for patients seeking full spectacle independence across near, intermediate, and distance. Most suitable for patients with stable prescriptions, healthy retinas, and regular pupils. Dry eye, if present, can usually be treated prior to surgery. This is the lens type most of our patients choose, in line with ESCRS Clinical Trends Survey data showing trifocal IOLs account for approximately 50% of presbyopia-correcting IOL cases across Europe.
The three trifocal IOLs we offer:
- Alcon PanOptix — Strong performance across intermediate distances (computer screens, car dashboards). Often recommended for office workers and patients who drive frequently.
- Zeiss AT LISA — Well-established track record in high-prescription eyes; often our choice for complex or high-hyperopia cases.
- PhysIOL FineVision — Well-tolerated glare/halo profile at night; often recommended for patients sensitive to light scatter or who do a lot of night driving.
Your surgeon will recommend the specific lens at consultation based on your biometry, pupil size, corneal topography, and lifestyle.
Blended Monovision and Multifocal Toric Options
Blended monovision with monofocals is also available as an alternative for patients who want reduced glasses dependence but are unsuitable for multifocals — for example, those with certain macular conditions or occupations where trifocal halos would be unacceptable.
For patients with astigmatism who also want full spectacle independence, multifocal toric IOLs combine trifocal vision (distance, intermediate and near) with astigmatism correction in a single lens. RLE can correct astigmatism up to approximately 12.00 dioptres.
After Surgery: Neuroadaptation & Trade-offs to Understand
What to expect in the weeks and months after surgery
Vision after trifocal lens implantation takes time to settle. Distance vision is usually the first to stabilise, typically within 24 to 48 hours. Near vision can take one to four weeks to fully adjust as the eye heals.
Beyond the initial healing, the brain undergoes a process called neuroadaptation — learning to automatically select the right focal zone from the three available. This is not a complication; it’s a normal part of adapting to Multifocal/Trifocal IOLs. Most patients fully adapt within three to six months, though some visual effects, such as mild glare and halos at night, can take up to a year to fully resolve.
Trade-offs to understand
No intraocular lens is perfect. Trifocal IOLs provide the widest range of unaided vision but can produce:
- Mild glare and halos at night — most noticeable in the first few months, usually improving as the brain adapts
- Slightly reduced contrast sensitivity in low-light conditions compared to monofocals
- Rare need for fine-tuning — a small percentage of patients benefit from a top-up laser procedure to sharpen vision after initial healing (included in our 12-month aftercare)
Monofocal IOLs have fewer visual disturbances but typically require reading glasses afterwards.
The right lens for you depends on what matters most in your daily life. This decision is made together at your consultation, based on your prescription, eye anatomy, pupil size, occupation, and lifestyle — not on a default template.
Our approach revolves around prioritising your optimal well-being throughout your Refractive Lens Exchange journey.
Prior to your consultation
Your first point of contact will be with Precision Vision London’s highly trained patient coordinators, who will discuss your prescription, lifestyle and suitability before any consultation fees are charged.
Treatment
RLE is a day-case procedure under local anaesthetic, taking approximately 20 minutes per eye. Both eyes can usually be treated the same day. Dr Almousa performs every procedure personally using the Alcon Refractive Suite.
Consultation
Your two-hour consultation includes full diagnostic imaging, biometry, topographic mapping and a personalised treatment plan discussed with your surgeon. Lens selection is tailored to your individual eye anatomy and lifestyle.
Aftercare
Your 12-month aftercare programme includes scheduled post-operative reviews, all medication for the first month, 24-hour telephone access, and laser fine-tuning if required — all included in the price.
How Long Does Recovery Take?
Most patients notice a significant improvement in vision within 24 to 48 hours of surgery. Near vision can take one to four weeks to fully adjust as the eye settles.
Typical recovery timeline:
- Day 1: Post-operative check with Dr Pillai and the clinical team
- Days 2–3: Vision begins to stabilise; driving is usually possible once your consultant confirms your vision meets the legal standard
- Days 3–5: Most patients return to office-based work
- Up to 4 weeks: Near vision continues to refine; some dryness is normal during healing
- 6 weeks: Most restrictions on physical activity and sport are lifted
- Up to 12 months: Aftercare programme continues with scheduled reviews
You will be given antibiotic and anti-inflammatory eye drops to use during recovery. Your clinical team will provide written instructions and remain available throughout the aftercare period.
When to Contact Us Immediately
Please contact the clinic without delay if you experience any of the following after surgery:
- Severe or worsening eye pain
- Sudden loss of vision
- Flashing lights or a sudden increase in floaters
- Significant discharge from the eye
- Any symptom you feel unsure about
Our team is available 24 hours a day following your treatment.

Private Refractive Lens Exchange at Precision Vision London
Refractive Lens Exchange is classified as an elective vision correction procedure and is not funded by the NHS. Patients seeking RLE in the UK are treated privately.
At Precision Vision London, private care means:
- Consultant-led from start to finish. Dr Almousa performs every RLE procedure personally. You will not be treated by a trainee or rotating registrar.
- Continuity of care. You see the same clinical team across consultation, surgery, and all 12 months of aftercare.
- The full range of premium intraocular lenses. The NHS typically offers a standard monofocal lens. We select from monofocal, multifocal, trifocal, and toric IOLs based on what best suits your eyes and lifestyle — with no manufacturer affiliations influencing the choice.
- No waiting lists. Consultations are typically available within one to two weeks, and surgery is scheduled at your convenience.
- Two-hour consultation with full diagnostic imaging, not a short NHS-style review.
- 24-hour post-treatment telephone access to our clinical team.
Does Private Medical Insurance Cover RLE?
Private medical insurance policies typically do not cover elective RLE, as it is classified as vision correction rather than treatment for disease. Some policies may contribute towards consultation fees or diagnostic imaging. Precision Vision London is recognised by Bupa, Cigna, Aviva, WPA, The Exeter, Allianz, and Simplyhealth — please contact us with your policy details to confirm your coverage.
If you have an early cataract that meets clinical criteria for treatment, your insurer may cover the surgical element while you pay the difference for premium lens upgrades. We can provide documentation to support your insurance enquiry.
RLE vs Laser Eye Surgery: Which is Right for You?
Two Different Approaches to Vision Correction
Laser eye surgery (LASIK, LASEK, PRK) and Refractive Lens Exchange are both vision correction procedures, but they work very differently.
Laser eye surgery reshapes the surface of the cornea to change how light is focused onto the retina. It is most suitable for patients in their 20s to early 40s with stable, moderate prescriptions and healthy corneas.
Refractive Lens Exchange replaces the lens inside the eye. It is typically more suitable for:
- Patients aged 40 and over, particularly those with presbyopia
- Prescriptions outside the safe range for laser surgery
- Patients with thin or irregular corneas
- Those with early cataracts forming
- Anyone who wants a permanent solution that also prevents future cataracts
Published clinical research indicates that, particularly for patients with high degrees of long-sightedness (hyperopia), RLE often yields a more stable and predictable result than laser surgery.
An in-person consultation is the only way to confirm which procedure is right for your eyes.
What Are the Risks of Refractive Lens Exchange?
A Strong Safety Record — But Risk is Never Zero
Refractive Lens Exchange is a well-established procedure with a strong safety record, but the risk of complications is not zero. Your surgeon will discuss your individual risk factors at the consultation.
Data from the Royal College of Ophthalmologists Cataract Surgery Commissioning Guidance shows that 85% of patients achieve refraction within ±1.00 dioptre of target after cataract/lens surgery, with posterior capsular rupture (the main intraoperative complication) occurring in approximately 1–2% of cases nationally. Careful patient selection, surgeon experience, and the use of current technology further reduce these risks.
Dr Almousa will discuss your individual risk profile in full during your consultation. Informed consent is an essential part of our process.
A clouding of the lens capsule (where the lens sits), not the lens itself. It is called "secondary cataract" but it is not a cataract — a cataract is the clouding of the lens, while PCO is a clouding of the lens capsule. It usually occurs due to the healing process after surgery and there is no way to predict who will heal like this. Treatable with a simple YAG laser procedure, which is included if it develops within the first 12 months of aftercare. If it occurs after the 12-month aftercare period, the YAG laser procedure will be charged separately.
Common in the first few months, especially at night with multifocal IOLs. Usually reduce over time.
A rare infection inside the eye. With the antibiotic drops provided after surgery, this risk is minimised significantly. Requires urgent treatment but is uncommon when surgery is performed in a properly sterilised clinical environment.
Some patients need a mild glasses prescription after surgery. This can happen as part of the natural healing process. Can often be corrected with laser fine-tuning, which is included in our 12-month aftercare.
A serious but rare complication, primarily affecting patients with very high myopia. Long-term follow-up studies report retinal detachment in approximately 3.2% of high-myopia RLE cases in published series.

Refractive Lens Exchange FAQ's
Refractive Lens Exchange starts from £3,000 per eye (from £6,000 for both eyes) for monofocal lenses, rising to £3,995 per eye (from £7,990 for both eyes) for multifocal toric lenses. Final pricing depends on the lens type recommended at your consultation. Consultation is free if you proceed with surgery; a £300 booking deposit is required to reserve your consultation. Finance is available from £37.10 per month (60 months at 9.9% APR, subject to status).
The procedure takes around 20 minutes per eye. It is performed as a day case under local anaesthetic, and both eyes can usually be treated on the same day.
The surgical technique is identical. The difference is the reason: cataract surgery removes a cloudy lens to restore vision, while RLE removes a clear lens to correct refractive error and reduce dependence on glasses.
There is no upper age limit for RLE, provided your eyes are healthy. Many of our patients are over 60. Suitability is determined by the health of your eyes, not age alone.
With trifocal IOLs, most patients achieve full or near-full spectacle independence. With monofocal IOLs, you will typically still need reading glasses. Your lens choice at the consultation determines the outcome.
There is no single "best" IOL. The right choice depends on your prescription, eye anatomy, pupil size, lifestyle and occupation. Most of our patients choose a trifocal IOL for full spectacle independence. Patients with demanding night vision requirements or early macular changes are often better suited to a monofocal IOL. Your surgeon will recommend the specific lens at consultation based on your biometry and lifestyle.
Most patients are able to drive two to three days after surgery, once their consultant confirms their vision meets the UK legal driving standard. Distance vision typically stabilises within 24 to 48 hours. Never drive until your consultant has confirmed you are safe to do so.
No. Refractive Lens Exchange is classified as an elective vision correction procedure and is not funded by the NHS. It is available privately at clinics like Precision Vision London.
Private medical insurance policies typically do not cover elective RLE, as it is classified as vision correction rather than treatment for disease. Some policies may contribute towards consultation or diagnostic fees. Precision Vision London is recognised by Bupa, Cigna, Aviva, WPA, The Exeter, Allianz, and Simplyhealth — please contact us with your policy details to confirm your coverage.
Yes, in most cases. Same-day bilateral treatment is suitable for most patients and is confirmed during your consultation.
No. The lens sits inside the capsular bag where your natural lens used to be. There are no nerves in that part of the eye, so you will not feel it, and no one will be able to see it.

Stories from RLE Patients
Below are stories from patients who have undergone Refractive Lens Exchange or Clear Lens Exchange at Precision Vision London.
“I felt very confident with the service I received. The eyes are a difficult area to make the decision to go ahead with surgery, but I was reassured at all times. Everybody was very nice, friendly and confidence-inspiring. I now have 20/20 vision, probably for the first time since I was about 7-8 years old, 42-43 years!“
— Sue D · Lens Replacement
“The whole experience of my Clear Lens Exchange procedure was amazing. The level of care and attention I received was exceptional. I felt completely relaxed and confident throughout, and even though there were several other people having the same procedure as myself, you made me feel like the ‘only one.’”
— G. Margaret · Clear Lens Exchange
“The whole process is very well organised. The CLE treatment I received was straightforward, painless, and most professionally carried out — about 15 minutes per eye. After wearing spectacles for over 53 years with a +9 prescription, the result is amazing. Peripheral vision is superb, and being able to see others clearly when swimming is a whole new experience.“
— Geoffrey H · Clear Lens Exchange
“I had worn contact lenses for over 25 years, and my prescription was -11. Laser eye treatment was not an option, so I was recommended Lens Replacement. I was apprehensive, but it has been life-changing. My distance vision is better than it has ever been. I have now done much more swimming than I have ever done, as I can see in the water. I do have to wear reading glasses, but this is a small price to pay.”
— Elizabeth C · Lens Replacement
