The EVO ICL is an implantable collamer lens — a soft, biocompatible lens placed permanently inside the eye, behind the iris and in front of your natural lens, to correct short-sightedness like a contact lens built into the eye. Because it removes no corneal tissue, it can correct myopia up to around −18D — well beyond laser’s safe range — and it is fully reversible.
What is the EVO ICL?
The ICL works like a contact lens that lives inside the eye. The EVO generation introduced a central micro-opening, the KS-AquaPORT, which lets the eye’s natural fluid flow freely around the lens. With older ICLs the surgeon had to make a separate small hole in the iris (a peripheral iridotomy) beforehand to prevent pressure build-up; the central port means that step is generally no longer needed, which simplifies the procedure, improves comfort and reduces some pressure-related risks. The port is invisible to you and does not affect vision quality, and EVO/EVO+ also offer a slightly wider optical zone.
It is a private, self-pay treatment performed by consultant refractive surgeons at our South England partner clinics, with UK-wide guidance through your assessment. The ICL corrects distance vision and is especially valuable for high myopes and thin corneas; it does not stop the age-related need for reading glasses (presbyopia).
EVO ICL vs laser options
How EVO ICL surgery is performed
Surgery is an outpatient procedure under anaesthetic drops, sometimes with light sedation to help you relax — no general anaesthetic. It takes around 15–20 minutes per eye. Through a tiny self-sealing incision the surgeon inserts the folded, custom-ordered collamer lens, which gently unfolds into position behind the iris and in front of your natural lens; a toric lens is rotated to the precise axis of your astigmatism. Because the EVO lens has the central KS-AquaPORT, a separate iridotomy is generally not needed. The eyes are usually treated on the same day or a few days apart, and you go home the same day with protective drops.

Book your suitability assessmentRecovery timeline
First hours – day 1
One of the fastest recoveries in refractive surgery: vision is usually noticeably clear within hours to the next day. The eye may feel gritty and light-sensitive for a day or so.
Day 1–2
Most people return to desk work and can drive once they comfortably meet the legal vision standard. Early reviews check the lens vault and your eye pressure.
Weeks 1–4
Anti-inflammatory and antibiotic drops are used for a few weeks. Any night-time halos ease. Avoid eye-rubbing, swimming, saunas and dusty environments as advised.
Ongoing
The great majority of ICLs are never removed and provide stable vision for years, with periodic endothelial cell-count and pressure checks at review.
How much does EVO ICL cost?
UK 2026 self-pay EVO ICL is typically £3,500–£4,500 per eye for the standard lens, or £4,000–£5,000 per eye for the EVO Toric lens that also corrects astigmatism, giving roughly £7,000–£10,000 for both eyes as an all-inclusive package. The suitability assessment is £200–£400 and is often redeemed against surgery. The price includes the premium collamer lens, custom-ordered to your prescription, and usually the medications and aftercare. Most clinics offer 0% or low-rate finance from around £150–£350 a month. Always ask for one written all-in figure for both eyes that states whether toric lenses and the full aftercare are included. See our ICL cost guide for detail.

What is the EVO ICL, and how is it different from the older ICL?
The ICL is an implantable collamer lens, a soft, biocompatible lens placed permanently inside the eye, behind the iris and in front of your natural lens, to correct short-sightedness like a contact lens built into the eye. The EVO generation introduced a central micro-opening called the KS-AquaPORT, which lets the eye’s natural fluid flow freely around the lens. With older ICLs the surgeon had to make a separate small hole in the iris (a peripheral iridotomy) beforehand to prevent a pressure build-up; the central port means that step is generally no longer needed, which simplifies the procedure, improves comfort and reduces some pressure-related risks. The central port is not visible to you and does not affect the quality of vision. EVO and EVO+ also offer a slightly wider optical zone.
EVO ICL or laser eye surgery — which is better for high myopia?
For high short-sightedness the ICL often has the edge. Corneal laser procedures such as LASIK, SMILE and SmartSight work by removing tissue from the cornea, so there is a limit to how strong a prescription they can safely treat and how thin a cornea they can work on; pushing beyond those limits risks weakening the cornea. The ICL removes no tissue and can correct myopia up to around −18 dioptres, well beyond laser’s safe range, and tends to give excellent quality of vision at high prescriptions, with the bonus of being reversible. Its trade-off is that it is intraocular surgery and depends on having enough space inside the eye. For low-to-moderate myopia with a healthy cornea, laser is often simpler and cheaper; for high myopia or thin corneas, the ICL is frequently the better choice. Your assessment decides which suits your eyes.
What prescriptions can EVO ICL treat?
EVO ICL treats a very wide range of short-sightedness, commonly myopia from around −3 up to about −18 dioptres, which is far beyond what corneal laser surgery can safely correct. The EVO Toric version simultaneously corrects astigmatism, typically up to around −6 dioptres of cylinder. The exact range suitable for your eyes depends on your individual anatomy, particularly the depth of the anterior chamber and the health of the corneal endothelium, which are measured at assessment. Because the lens is custom-ordered to your prescription and eye dimensions, it can be tailored to strong and complex prescriptions that leave glasses thick and contact lenses hard to tolerate, which is exactly why many high myopes choose it.
How long is the recovery after EVO ICL?
Recovery is fast — the ICL gives one of the quickest visual recoveries in refractive surgery. Vision is usually noticeably clear within hours to the next day. For the first day or two the eye may feel gritty and be light-sensitive, and you may see some halos around lights at night that ease over the following weeks. You use anti-inflammatory and antibiotic drops for a few weeks. Most people return to desk work within a day or two and can drive once they comfortably meet the legal vision standard. You should avoid eye-rubbing, swimming, saunas and dusty environments for the period your surgeon advises, and avoid strenuous activity for a short time. Early reviews check that the lens is sitting at the correct height (vault) and that your eye pressure is normal.
Is ICL surgery available on the NHS?
No, ICL surgery to correct short-sightedness is an elective, lifestyle procedure and is not routinely funded by the NHS, so EVO ICL is a private, self-pay treatment. The NHS only very rarely funds a phakic lens, and then for specific clinical reasons such as an extreme prescription with a severe difference between the two eyes and contact-lens intolerance, decided on an individual basis. For most people the practical financial route is the clinic’s interest-free or low-rate finance rather than the NHS or private medical insurance, which generally excludes elective refractive surgery.
