How ICL Surgery Works?
At Precision Vision London, we offer advanced ICL (Implantable Collamer Lens) Surgery in Harley Street, the heart of London’s renowned medical district. ICL surgery provides a long-term, lens-based solution for people who want freedom from glasses and contact lenses but may not be suitable for laser eye surgery.
Unlike LASIK or other laser procedures, ICL surgery does not remove any corneal tissue. Instead, a soft biocompatible lens is carefully implanted between your natural lens and the iris (the coloured part of your eye). This lens works in harmony with your eye to correct short-sightedness, Long-sightedness and astigmatism, offering high-definition vision with natural sharpness and contrast. It is the only vision correction procedure that is completely reversible, as it leaves the cornea untouched and unaltered.
The procedure itself is quick, safe and virtually painless, usually taking around 20 to 30 minutes per eye. Recovery is remarkably fast; most patients notice significantly improved vision within hours. Because the ICL can be removed or replaced if needed, it provides both flexibility and peace of mind.
ICL surgery is an ideal choice for patients with thin corneas, dry eyes or high prescriptions who may not be suitable for laser correction. Every lens is custom-made to match the patient’s exact eye measurements, ensuring a perfect visual outcome.
Are You Eligible for ICL Surgery?
Most adults seeking long-term freedom from glasses or contact lenses are suitable candidates for ICL (Implantable Collamer Lens) Surgery, a safe and effective alternative to laser vision correction. ICL surgery is designed for individuals with short-sightedness (myopia), long-sightedness (hyperopia), or astigmatism who want permanent vision correction without altering the corneal structure.
You may be an ideal candidate for ICL Surgery if you are between 21 and 45 years old and your prescription has remained stable for at least 12 months. This procedure is particularly suitable for individuals with thin or irregular corneas who may not qualify for laser eye surgery. If you’re seeking a reversible, long-term vision correction solution that offers exceptional clarity and comfort, ICL Surgery could be the perfect choice for you.
You may not be suitable for ICL Surgery if you have severe eye conditions such as glaucoma, cataracts, advanced retinal disease, or uncontrolled systemic health issues such as diabetes or autoimmune disorders. In such cases, your surgeon will carefully assess your eye health and discuss alternative options.

Implantable Contact Lens Treatment FAQ's
EVO Visian ICL is the treatment of choice for those patients between the ages of 21 to 45 who are not ideal candidates for laser eye surgery due to high prescriptions, thin corneas, dry eye syndrome or other reasons. It can also be used to help patients suffering from Keratoconus who have had cross-linking treatment or where the disease has stabilised.
EVO Visian ICL treatments have been performed for over 20 years and more than 900,000 ICL procedures have been conducted successfully worldwide. Prior to being available, ICL lenses were subjected to extensive research and development. They have been approved in Europe since 1997 and FDA approved in the US since 2005.
The US military regularly implant EVO Visian ICL for their servicemen/women and have been monitoring the results. Their study concluded that EVO Visian ICL provides “excellent visual and refractive results”. The study showed excellent vision quality and stability of the lens inside the eye, even in combat. The treatment has shown to be an effective, safe, predictable and stable way to correct high and low levels of short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism.
As with any procedure, safety is not only dictated by the technology used but also by the surgeon performing the treatment. Precision Vision surgeons are internationally-renowned surgeons and recognised experts in the field of lens treatments and teach other surgeons how to perform this procedure.
Implantable Contact Lenses are suitable for a wide range of prescriptions from -23D to +11 with astigmatism up to 6D. Precision Vision has made history by being the first clinic in the UK to treat an astigmatic hyperope (a long-sighted individual with a high prescription and significant astigmatism).
EVO Visian ICL is the standardised treatment for higher prescriptions and is recommended by the American Association of Cataract and Refractive Surgery (ASCRS) and the European Association of Cataract and Refractive Surgery (ESCRS).
The EVO Visian ICL is made of Collamer, a highly biocompatible advanced lens material which contains a small amount of purified collagen. Collamer does not cause a reaction inside the eye and contains an ultraviolet blocker that protects the eye.
There is no chance of rejection as the EVO Visian ICL is made of a Collamer material that is completely biocompatible with the body’s natural chemistry.
The EVO Visian ICL implant is designed to remain inside the eye indefinitely. It can be thought of as a permanent contact lens that is maintenance free. However, the lens can be removed at any time in the future should it be necessary.
Implantable Contact Lenses (ICL) are often referred to as a phakic IOLs meaning a lens is implanted into an eye with the natural lens in place. An Intra-Ocular Lens (IOL) replaces the natural crystalline lens and is used to treat patients aged 45+ that require reading glasses (presbyopia) or have cataracts.
EVO Visian ICL lenses are much smaller than a contact lens and they are implanted behind the iris (the coloured part of the eye) and they are not visible to those looking at you. Given the location of the implanted lens, it will remain permanently in place and cannot be felt.
No, you cannot feel the lens.
The advantage of the EVO Visian ICL is that it can permanently correct your vision, yet no natural tissue is removed in any way during the procedure. If for the unlikely reason you need or wish to remove your EVO Visian ICLs in the future, it can be done.
After attending the consultation, tailor-made lenses are ordered from the manufacturer. Lenses sometimes can take up to 4 to 8 weeks to be manufactured and sent to our clinic.
Once the lenses have arrived the procedure will take approximately 30 minutes per eye and we will treat each eye on two consecutive days, meaning that the amount of time spent with one eye uncorrected is minimised, allowing for a faster recovery.
Anaesthetic drops are applied to numb the eye meaning that nothing is felt throughout the treatment. The drops wear off without any side effects soon after the procedure is finished.
Visual improvement is noticeable almost immediately after treatment and patients can see 90-95 % better within two to three days following treatment.
Patients are required to attend regular aftercare appointments the first year after treatment; these are included in the cost of your treatment. There is no other maintenance required but we recommend having an eye examination every 2 years at the Precision Vision clinic or with a qualified person in the field.
ICL surgery does not prevent or slow down cataract formation. However, if a cataract operation is required, the EVO Visian ICL implants can be safely removed and normal cataract surgery can be performed.
Every EVO Visian ICL implant is customised to each individual’s prescription and the lens is tailor-made. The procedure requires more extensive preoperative assessments, measurements and calculations. There is also a larger surgical team required for the procedure.
Laser surgery permanently modifies the cornea and, as ICL treatment does not affect the cornea, it is possible to have EVO Visian ICL after Laser treatment.

ICL Treatment Process
Upon reaching the Harley Street clinic for your surgery, our skilled and welcoming medical team will assist you throughout the entire process. Typically, we perform surgery on both eyes during the same session, though there may be specific exceptions based on the surgeon’s assessment.
We prefer this approach to reduce the visual disparity and discomfort that can occur when treating eyes separately. This method helps streamline the post-operative experience for our patients and shortens the overall recovery duration.
The procedure begins with numbing drops to anaesthetise the eye. No needles are involved. You’ll receive a sedative, and drops will be used to dilate the pupil. A small self-healing incision is created on the cornea’s edge. For patients with hyperopia (long-sightedness), a laser will create two tiny holes in the iris, known as an iridectomy.
The custom-designed lens is then folded and positioned in front of your natural lens. Since the micro-incision heals itself, no stitches are required. Our dedicated nurse will explain all necessary precautions and medication instructions before you leave. Your follow-up care commences with an eye examination the following day.
Following your ICL procedure, you’ll receive three types of eye drops: anti-inflammatory, antibiotic, and moisturising. Clear instructions will be provided regarding the timing of these drops.
ICL Lenses
Powerful distance-vision correction without reshaping your cornea. EVO Visian ICL is a tiny, biocompatible lens (made from Collamer®️) placed inside the eye, leaving your natural Lens untouched. It’s designed to correct distance prescriptions with exceptional clarity, especially helpful for high prescriptions, thin corneas, or dry-eye-prone patients. The Lens is removable, so your options stay open as your visual needs evolve.
Who it’s for
1. Myopia (short-sightedness) and astigmatism, including higher prescriptions that may not be ideal for laser eye surgery.
2. Patients seeking a cornea-preserving and reversible solution with crisp, high-contrast vision.
The ICL range we use
To tailor outcomes precisely, we select from the latest EVO Visian ICL designs during your clinical work-up (availability is confirmed at consultation):
1. Simple Lens – for long sight (hyperopia) or short sight (myopia)
2. Myopic Toric Lens – for myopia with astigmatism
3. Hyperopic Toric Lens – for hyperopia with astigmatism
What ICL does and doesn’t treat
EVO Visian ICL focuses on the distance field of vision. It doesn’t correct or prevent presbyopia (the age-related need for reading glasses). If presbyopia develops, you may need readers. For people wanting a full range of vision (distance, intermediate and near), Lens Replacement (RLE) may be more suitable.
Safety-led technology
We use the latest EVO Visian ICL designs, including the V4C with CentraFlow®️ (a central aquaport). This innovation helps maintain natural fluid flow in the eye and typically removes the need for a peripheral iridotomy (the tiny opening sometimes made in the iris), streamlining the procedure while supporting excellent visual quality.
Why patients choose ICL at Precision Vision London
1. Cornea-preserving (no tissue removal) and reversible.
2. High-definition distance vision, even in high prescriptions
3. Often dry-eye-friendly compared with some laser options
4. Harley Street expertise with personalised diagnostics and lens planning
