In short: the IC-8 Apthera (AcuFocus / Bausch + Lomb) is a one-piece acrylic lens carrying a 3.23 mm opaque ring with a tiny 1.36 mm central aperture. Like a camera stopped down to a small f-stop, that pinhole extends your range of clear vision by roughly 3 dioptres and screens out the distorted light from an irregular cornea. It is implanted in your non-dominant eye, with a high-quality monofocal lens in your dominant eye. Private UK cost in 2026 is typically £3,200–£4,800 per eye as a lens upgrade, or £4,500–£6,800 per eye for an all-inclusive package.
What the IC-8 Apthera is and who it suits
Most premium lenses split or stretch incoming light to create more than one focal point — which is why diffractive trifocals demand a clean, regular cornea and can produce halos. The IC-8 works on a completely different principle: it simply blocks the peripheral, defocused rays and lets only the central, well-focused light through a small aperture. The result is a long, continuous depth of focus from distance through arm’s length to near reading, with an unusual tolerance for residual prescription and corneal irregularity.
That makes it the lens of choice when other premium options are off the table. The strongest candidates are eyes with an irregular cornea — after LASIK, PRK or radial keratotomy (RK), in mild stable keratoconus, or after a corneal transplant (DALK or PK) with a settled graft. In these eyes the small aperture filters out the higher-order aberrations that would blur a trifocal or EDOF lens, delivering far better uncorrected vision than any diffractive lens could. It is also a sensible pick for patients who want extended range but are wary of trifocal night-time halos.
The IC-8 is implanted in one eye only — the non-dominant eye — because the small aperture slightly dims that eye in low light. Your dominant eye receives a crisp monofocal lens, and your brain blends the two for comfortable all-round vision. If you have advanced macular disease, glaucoma with central field loss, or a high risk of future peripheral retinal treatment, a different lens is usually safer; your consultant confirms suitability after scans.
Your lens options
For an irregular cornea or maximum forgiveness, the IC-8 leads — but it is not the only route. Here is how it compares with the alternatives your consultant may discuss.

Book your assessmentHow IC-8 surgery is done
IC-8 implantation is routine day-case cataract surgery with one extra planning step. After detailed biometry and corneal tomography to confirm your cornea’s shape and choose your companion lens, the operation itself takes around 15 minutes under anaesthetic eye drops — no needles, no general anaesthetic, no overnight stay.
Through a 2.2 mm incision the surgeon removes the cloudy natural lens by phacoemulsification, then implants the folded IC-8 into the lens capsule and carefully centres the small aperture on your line of sight. Centration matters more than with an ordinary lens, so your consultant verifies it under the microscope before finishing. Antibiotic is given inside the eye, the wound self-seals without stitches, and you go home the same day with drops and a protective shield for the first few nights.
Recovery and what to expect
Day 1
Distance vision in the IC-8 eye is usually already useful (6/12 or better). The eye may feel gritty and look a little red — both settle quickly.
Week 1
Most people return to driving between day 1 and day 3 once cleared. Drops continue; intermediate and near vision steadily sharpen.
Weeks 4–12
Neuroadaptation: your brain learns to favour the brighter monofocal eye in dim light and the IC-8 eye for arm’s-length and reading. Any early dimness or faint ring effects fade.
Long term
The IC-8 is permanent. A simple YAG laser treatment clears any later clouding of the capsule; the lens can be exchanged in the rare event it is ever needed.
How much the IC-8 Apthera costs
In 2026 the IC-8 Apthera in the UK typically costs £3,200–£4,800 per eye as a lens upgrade above a standard monofocal cataract package, or £4,500–£6,800 per eye as an all-inclusive package covering your consultant assessment, advanced biometry and corneal tomography, the lens, the day-case surgery and a 12-month aftercare programme. Because the IC-8 goes in one eye with a monofocal companion in the other, a typical bilateral plan totals around £7,700–£11,000.
The NHS funds cataract surgery with a standard monofocal lens only, so the IC-8 is accessed privately. Most major UK insurers (Bupa, AXA Health, Aviva, Vitality, WPA) cover the underlying cataract operation with pre-authorisation; the premium-lens upgrade is normally self-pay. We itemise the insured and self-pay parts clearly before you book. See the full price list or compare with the standard cataract surgery options.
IC-8 Apthera FAQs
How much does private IC-8 Apthera lens surgery cost in the UK in 2026?
Expect £3,200–£4,800 per eye as a lens upgrade above a standard monofocal cataract package, or £4,500–£6,800 per eye for an all-inclusive IC-8 package covering your consultant assessment, advanced biometry and corneal tomography, the IC-8 Apthera lens, the day-case surgery and 12 months of aftercare. As the IC-8 is implanted in one eye with a monofocal lens in the other, a typical bilateral plan totals around £7,700–£11,000.
What is the IC-8 Apthera and how does it work?
It is a one-piece acrylic intraocular lens carrying a 3.23 mm opaque ring with a 1.36 mm central aperture. Like a small camera aperture, that pinhole blocks peripheral, out-of-focus light and lets only the central, sharply focused rays through — extending your depth of focus by about 3 dioptres so you see clearly from distance through intermediate (66 cm) to near (40 cm). The same effect screens out distortion from an irregular cornea, making the IC-8 unusually forgiving.
Is the IC-8 the best lens after LASIK, RK or in keratoconus?
For an irregular cornea, it is often the strongest option. Post-LASIK, post-PRK, post-RK eyes, mild stable keratoconus and settled corneal transplants are among the best indications. Diffractive trifocals (PanOptix, Synergy, FineVision) are generally unsuitable in irregular corneas, whereas the IC-8 small aperture filters the corneal distortion and forgives residual prescription, delivering far better uncorrected distance, intermediate and near vision than a multifocal or EDOF lens could in the same eye.
Does the NHS or my insurance pay for the IC-8 Apthera?
The NHS funds cataract surgery with a standard monofocal lens only, so premium upgrades like the IC-8 are accessed privately. Most major UK insurers (Bupa, AXA Health, Aviva, Vitality, WPA) cover the underlying cataract operation when the cataract is visually significant, with pre-authorisation; the premium-lens upgrade element is generally paid by you directly. Our team prepares the insurance pre-authorisation and itemises the insured and self-pay parts before booking.
Will my vision be dim at night with an IC-8?
The small aperture reduces the light reaching the retina in the implanted eye, so that eye is dimmer in low light than your monofocal companion eye. Most people neuroadapt within 4 to 12 weeks — the brain learns to use the brighter eye for dim conditions and the IC-8 eye for intermediate and near. The large majority drive safely at night afterwards, though a minority notice faint rings around bright lights that ease with time. If you do most of your driving at night, discuss this carefully at your consultation.
IC-8 Apthera or a trifocal lens — which is better?
It depends on your cornea. In a regular cornea a diffractive trifocal (PanOptix Pro, Synergy, FineVision) gives the sharpest unaided near reading but needs a clean cornea and can produce more night-time halos. The IC-8 is the better choice when the cornea is irregular (post-LASIK, post-RK, mild keratoconus, post-transplant), when forgiveness of residual prescription matters, or when you are sensitive to halos. The IC-8 goes in the non-dominant eye with a monofocal companion; trifocals are usually placed in both eyes.
