Laser Eye Surgery Cost Calculator
What will LASIK, LASEK or SMILE really cost you? Estimate your per-eye and both-eyes price
Last updated: July 2026
How much does laser eye surgery cost in the UK?
Most people having laser eye surgery in the UK pay somewhere between £1,700 and £3,500 per eye, so a typical both-eyes bill lands between roughly £3,400 and £7,000. Those are market ranges, not quotes: the price you are actually offered depends on the procedure (LASIK, LASEK/PRK or SMILE), how strong and how complex your prescription is, the technology the clinic uses and whether you are in a high-street chain, an independent consultant-led clinic or a central London practice. This calculator turns those variables into a realistic per-eye and both-eyes estimate, adds a monthly finance illustration, and flags suitability questions worth raising at your assessment. It exists because the gap between advertised “from” prices and what patients really pay is one of the most common complaints in this market – going in with a sensible expectation makes the sales conversation much easier to navigate.
What actually drives the price
- Procedure type. Standard LASIK and surface treatments (LASEK/PRK) sit at the cheaper end. Wavefront or “custom” LASIK, which maps the eye's unique optical errors, costs more. SMILE – the keyhole technique with no corneal flap – is usually the most expensive because fewer UK clinics have the platform.
- Your prescription. Many clinics use price bands: a simple -2.00 short-sighted eye books the entry band, while high myopia, long-sight or meaningful astigmatism pushes you into the top band. This is exactly where “from” pricing misleads.
- Clinic and surgeon. High-street chains benefit from volume and price keenly. Independent clinics where a named consultant does your assessment, surgery and aftercare generally charge more – some patients think that continuity is worth the premium.
- Location. Central London carries the usual premium of roughly 10–25% over regional prices for the same procedure.
- What's bundled. Aftercare length, enhancement (re-treatment) rights and astigmatism correction are included at some clinics and charged separately at others – two “identical” headline prices can be hundreds of pounds apart once itemised.
LASIK vs LASEK vs SMILE – price and fit
| Procedure | Typical per-eye range* | Usually suits |
|---|---|---|
| LASIK (standard) | £1,700 – £3,000 | Most short-sight to around -8D, mild long-sight, fast recovery |
| LASIK (wavefront/custom) | £1,900 – £3,500 | Higher-order aberrations, night-vision concerns, larger pupils |
| LASEK / PRK | £1,700 – £3,200 | Thinner corneas, contact-sport players (no flap); slower recovery |
| SMILE | £2,200 – £3,500 | Short-sight including higher prescriptions, dry-eye-prone patients |

Worked example
Sam is 32, short-sighted at -4.25D with 1.50D of astigmatism, and is comparing standard LASIK at a high-street chain against an independent consultant-led clinic. At the chain, the calculator estimates £1,700–£2,100 per eye, so £3,400–£4,200 for both eyes – though the astigmatism means the quote will likely come in nearer the top of that band. At the independent clinic the range moves to £2,000–£2,600 per eye (£4,000–£5,200 both eyes). Spread over a typical 24-month interest-free plan, the midpoint works out at roughly £158–£192 a month. Sam's real decision is not just price: it is whether the cheaper quote includes the same aftercare period and enhancement rights as the dearer one.
Read the guarantee smallprint before you sign
Almost every clinic markets some form of “lifetime care” or “20/20 guarantee”. These are genuinely useful – but they are contracts, not promises, and the exclusions matter:
- Enhancement windows. Free re-treatment is often limited to a period (commonly 12 months, sometimes longer) or to cases where the original target correction was not achieved. Re-treatment years later, because your eyes changed naturally, is usually chargeable.
- Ageing is excluded. No laser guarantee covers presbyopia – the age-related change that makes reading glasses necessary from the mid-40s. Laser surgery does not prevent it.
- Conditions attach. Some lifetime schemes require you to attend paid annual check-ups at the clinic to keep the guarantee alive. Miss one and the cover can lapse.
- “20/20 or your money back” offers typically apply only to selected low prescriptions and have claim windows. Ask exactly which outcomes qualify and get it in writing.
A useful discipline: ask every clinic for a single itemised page showing the per-eye price for your prescription, what aftercare it includes, the enhancement policy and any guarantee conditions. Comparing those pages beats comparing adverts.
The NHS position – and free routes
The NHS does not fund laser eye surgery for ordinary short-sight, long-sight or astigmatism – it is classed as a lifestyle treatment, since glasses and contact lenses correct the same problem. NHS laser treatment is reserved for specific corneal or medical conditions. What you may be entitled to for free is the NHS sight test (children, over-60s, people on qualifying benefits, diabetics and others), which is the sensible, no-cost first step to an up-to-date prescription before you approach any clinic. If cost is the main barrier, remember that surgery is optional: modern contact lenses and spectacles remain the low-risk default the NHS supports.
Frequently asked questions
How much does laser eye surgery cost in the UK?
Most people pay roughly £1,700 to £3,500 per eye in the UK, depending on the procedure (LASIK, LASEK or SMILE), your prescription and the clinic. Both-eye treatment is usually double the per-eye price, sometimes with a small package discount. These are typical market ranges, not quotes – only a clinic assessment can price your eyes.
Is laser eye surgery available on the NHS?
Not for ordinary short-sight, long-sight or astigmatism. The NHS treats laser vision correction as a lifestyle choice, so you would pay privately. NHS-funded laser treatment exists only for specific medical conditions of the cornea. Glasses and contact lenses remain the free-at-assessment NHS route, and many people qualify for free NHS sight tests.
Which is cheapest – LASIK, LASEK or SMILE?
Standard LASIK and LASEK are usually the cheapest options and cost about the same. Wavefront or custom LASIK sits in the middle, and SMILE (keyhole lenticule extraction) is typically the most expensive because fewer clinics offer it and it uses newer laser platforms.
Why do clinics advertise laser eye surgery from £595 per eye?
Headline from-prices normally apply only to very low, simple prescriptions treated with the most basic package. Once astigmatism, a stronger prescription, wavefront technology or a full aftercare plan is added, most patients are quoted far more. Always ask for an itemised, per-eye written quote after your assessment.
What should a laser eye surgery quote include?
A complete quote should cover the pre-operative assessment, the procedure for both eyes, all routine aftercare appointments (usually 12 months) and the clinic's enhancement or re-treatment policy in writing. Check whether astigmatism correction is included or charged as an extra, and whether the lifetime guarantee has conditions such as attending annual check-ups.
Can I pay for laser eye surgery monthly?
Most large UK clinics offer finance, often interest-free over roughly 10 to 24 months, with longer terms available at interest. Finance is subject to a credit check and terms differ by clinic, so compare the total repayable, not just the monthly figure.
