Cataract surgery when you have high myopia works exactly as it does for anyone else — the clouded natural lens is removed and replaced with a clear intraocular lens. The difference for a very short-sighted eye is in the planning: the eye is longer than average, so the power of the new lens has to be calculated with more care, and the retina is checked closely first. Get those right and the result is often life-changing, because the implant can also correct most of the short-sight you have lived with for decades. At our partner clinics it starts from £2,900 per eye for a monofocal lens, £3,796 for EDOF and £4,300 for multifocal, all-inclusive of consultation, biometry, theatre, your lens and aftercare.
Cataract surgery when you're very short-sighted
High myopia usually means a prescription beyond about -6.00, and often a good deal stronger. The eyeball is physically longer than a typical eye, which is why glasses this strong are needed — and it is also why cataracts tend to show up a little earlier than average. Many people in this group have spent a lifetime in thick lenses or contact lenses, so the prospect of surgery that tackles both the cataract and the short-sight in one go is understandably appealing.
It is a realistic prospect. Once the cloudy lens comes out, the implant that replaces it is chosen to bring your focus much closer to normal. Most patients still keep a light pair of glasses for some tasks, but the days of −10 or −12 dioptre lenses are usually behind them.
What high myopia changes about your surgery
Three things get extra attention in a long, short-sighted eye, and your consultant will talk each of them through at the assessment.
Getting the lens power right. Standard implant-power formulas were built around average-length eyes and can drift in very long ones. We use precise optical biometry and modern long-eye formulas to pin the number down — the same careful measurement described on our IOL power calculation page. It is the single biggest factor in how close to your target you land.
The retina. Short-sighted eyes carry a somewhat higher lifetime risk of retinal problems, so the surgeon examines the back of the eye thoroughly before surgery and again afterwards. This is routine, not a reason to worry — but it is why we check, and why we ask you to report any sudden new flashes, a shower of floaters or a shadow spreading across your vision straight away.
Which lens suits the eye. Not every premium lens is a good fit for every myopic eye. Where the macula and retina are healthy, an EDOF or multifocal lens can give real glasses freedom. Where there is myopic thinning at the back of the eye, a reliable monofocal often gives the crispest, most dependable sight — and honesty about that trade-off is part of the job.
Very short-sighted and thinking about surgery? A consultation measures your eye properly and tells you what vision you can realistically expect afterwards.

The lens you choose shapes how much you rely on glasses afterwards. If you also have astigmatism — common alongside high myopia — a toric lens corrects it at the same time. Your consultant recommends the fit that suits your eye and your daily life.
If you are short-sighted but do not yet have a cataract, a refractive lens exchange uses the same operation electively, and younger high myopes are sometimes better suited to an EVO ICL instead. Your consultant will say which route fits you.
What happens during the procedure
Surgery is done under local anaesthetic eye drops — you are awake but feel no pain, just mild pressure and light. Each eye takes 15 to 25 minutes, and you are usually at the clinic for two to three hours including checks and a short rest.
- Numbing drops go in and the skin around the eye is cleaned with sterile solution.
- A tiny 2.2–2.8mm incision is made at the edge of the cornea, small enough to seal itself without stitches.
- Phacoemulsification uses a fine ultrasound probe to break up and remove the cloudy lens.
- Your chosen intraocular lens, calculated for your long eye, is folded, inserted and settled into place.
- The eye is shielded and you rest for 30–60 minutes before going home.
Recovery week-by-week
Most people see more clearly within a day, with full healing over about a month. Because short-sighted eyes carry a slightly higher retinal risk, do report any sudden flashes, new floaters or a shadow across your sight without delay — it is rare, but it is worth catching early.
Day of surgery
Vision is hazy for a few hours. Eye shield worn the first night. No driving or heavy lifting. Drops begin.
Days 1–3
Vision clears noticeably. Mild grittiness or watering is normal. Gentle activities and reading resume.
Week 1
First post-op review. Most patients are back to driving and working — no swimming or eye-rubbing yet.
Weeks 2–4
Vision refines. Drops continue. Any new glasses prescription is fine-tuned at week 4–6.
Beyond a month
Vision is settled. The second eye is scheduled if both are being treated.
Cataract surgery cost for high myopia
Prices are all-inclusive — consultation, biometry, theatre, your lens and aftercare, with no hidden extras. High myopia does not change the base fee; a toric lens for astigmatism is the only common add-on:
- Self-pay: from £2,900 per eye (monofocal); £3,796 EDOF; £4,300 multifocal.
- Insurance: recognised by Bupa, AXA Health, Aviva, Vitality, Cigna and WPA — we handle authorisation.
- Finance: 0% over 12 months, roughly £242/month for a monofocal lens.
