Private lens replacement surgery (Refractive Lens Exchange, or RLE) swaps your eye's natural lens for a permanent premium intraocular lens, correcting long sight, short sight and presbyopia in a single 20–30 minute day-case procedure under anaesthetic drops. Because the natural lens is removed, you can never develop a cataract in that eye. At our partner clinics RLE starts from £3,200 per eye for monofocal or EDOF lenses and from around £4,300 per eye for trifocal lenses, all-inclusive of consultation, surgery, lens and aftercare. This page focuses on what to expect as a patient — for the full clinical detail see our Refractive Lens Exchange treatment guide and the complete RLE cost breakdown.
What lens replacement surgery is — in plain terms
Inside your eye sits a clear natural lens that focuses light onto the retina. In your 40s and 50s this lens stiffens (causing the reading difficulty known as presbyopia), and later it clouds into a cataract. Lens replacement surgery is identical in technique to cataract surgery — but it is done before a cataract forms, to free you from glasses and contact lenses. The cloudy or stiffening natural lens is removed and a precision intraocular lens (IOL) is implanted in its place, chosen to match the vision you want.
Because the procedure removes the lens that would one day become a cataract, RLE is the only vision-correction surgery that takes future cataract surgery off the table entirely. For many patients in their 50s and 60s it is a more lasting solution than laser eye surgery, which only reshapes the cornea and leaves the ageing lens behind.
Is lens replacement right for me?
The honest answer comes from a consultation, not a website — but here is how we think about suitability. RLE tends to suit you well if you:
- Are over 50 and increasingly dependent on reading glasses or varifocals
- Are long-sighted (hyperopic), where laser surgery is often less predictable
- Have a prescription outside the safe range for laser eye surgery
- Want a one-time fix that also removes the risk of future cataracts
- Are starting to notice early lens cloudiness but not yet a true cataract
It may not be the first choice if you are under 45 with healthy accommodation, are highly short-sighted with retinal risk factors that need weighing carefully, or have an eye condition that should be treated first. Your surgeon will examine your eyes, measure them precisely, and tell you plainly whether RLE, laser, or simply updating your glasses is the right path. There is never any pressure to proceed.
Not sure if you're a candidate? A consultation includes diagnostic scans and a frank discussion of every option — including the option to do nothing.
Book a suitability assessmentChoosing your lens
The lens you choose shapes the vision you'll live with, so this is the heart of the consultation. Your surgeon recommends a lens family based on your eye anatomy, your prescription and how you actually use your eyes day to day. The full clinical range is set out in our implant lens guide.
Toric versions of each lens correct astigmatism at the same time. There is no single “best” lens — only the best lens for your eyes and your lifestyle, which is exactly what the consultation exists to find.
Your journey, step by step
Knowing what happens and when takes the anxiety out of surgery. Here is the path most of our RLE patients follow. You can read more about each stage in our patient journey overview.
1. First contact
Call or request a callback. Our nurse answers your questions and arranges a consultation at your nearest clinic — no GP referral needed.
2. Your consultation
Full eye examination, biometry scans and a relaxed discussion of options. You leave with a clear recommendation and a written quote, not a hard sell.
3. Preparing for surgery
We confirm your lens choice and surgery date and send simple preparation guidance. See preparing for surgery for the full checklist.
4. The day itself
You're at the clinic 2–3 hours. Surgery takes 20–30 minutes per eye under anaesthetic drops — you stay awake but feel no pain. You go home the same day.
5. Recovery & reviews
Vision clears over the following days. We see you at 1 week and 4 weeks. Full guidance is in our recovery section.
What recovery feels like
Most patients are pleasantly surprised by how gentle recovery is. Vision is hazy for the first few hours and often noticeably clearer by the next morning. Mild grittiness, watering or light sensitivity is normal and settles quickly with the drops we provide.
- First night: wear the protective shield; rest your eyes.
- Days 1–3: vision sharpens; most people read and watch TV comfortably.
- Week 1: back to work, driving and walking for most; no swimming or eye-rubbing yet.
- Weeks 2–4: vision keeps refining as the brain adapts to the new lens; second eye treated if both are planned.
Because a premium lens is designed to deliver a range of vision, your brain takes a little time to learn to use it — especially with EDOF and trifocal lenses. Our team supports you throughout that adaptation. For the complete week-by-week guide, see recovery.
Cost & what's included
Our RLE prices are all-inclusive: consultation, biometry, the surgery, theatre and hospital fees, your chosen premium lens, post-op drops and both follow-up reviews. There are no hidden extras.
- Self-pay: from £3,200 per eye (monofocal/EDOF); from £4,300 per eye (trifocal/multifocal).
- Insurance: RLE is usually an elective refractive procedure, so most policies do not cover it — we'll tell you honestly at consultation.
- Finance: 0% options available to spread the cost.
