Implantable collamer lens surgery may be an option if you want less reliance on glasses or contact lenses, particularly when your prescription or corneal measurements make laser treatment less suitable. At Precision Vision London on Harley Street, an eye assessment establishes whether an implantable lens is appropriate for you.
How does an implantable lens correct vision?
An ICL is placed behind the coloured part of your eye, the iris, and in front of your natural lens. It provides additional focusing power without removing the natural lens or reshaping the cornea with a laser.
The implant is intended to remain in the eye long term. It can be removed or exchanged through another operation if clinically appropriate. Removal is not a guarantee that the eye will return to its exact pre-surgery condition.
The Royal College of Ophthalmologists’ patient information explains this type of lens implantation and the alternatives to discuss.
Which implant would I need?
The lens choice depends on your prescription and eye measurements. Your clinician will explain the proposed model, what it is designed to correct and any remaining need for glasses.
| Decision | What it means for you |
|---|---|
| Prescription correction | The lens power is selected to address your prescription. Ask what vision is realistically expected afterwards. |
| Astigmatism | A toric lens may be considered where astigmatism correction is needed. |
| Lens sizing and position | Measurements establish whether there is adequate space and help determine a suitable implant. |
| Long-term care | Discuss the eye checks you will need after the initial recovery period. |
If you are long-sighted or have a condition such as keratoconus, ask which treatment and lens model are appropriate. These situations need individual assessment.
Could ICL be suitable for my eyes?
ICL may be considered for adults with a stable prescription, including some people who are unsuitable for laser correction. A high prescription or thin cornea does not automatically mean that an implant is safe or appropriate.
Your assessment needs to consider the space inside the eye, the corneal cell layer, the natural lens and overall eye health. The relevant age and prescription limits depend on the lens and your clinical circumstances.
Where appropriate, discuss laser vision correction or lens replacement with your clinician. Neither is automatically preferable based on age alone.
What does the treatment journey involve?
- Assessment. Your prescription, eye health and measurements are checked before a treatment is recommended.
- Lens planning. Discuss the implant, expected outcome, risks, alternatives and written quotation with your surgeon.
- Treatment arrangements. The team confirms the location, preparation instructions and arrangements for treating each eye.
- Follow-up. Attend the recommended reviews so healing, eye pressure and the position of the implant can be checked.
Arrange transport home after surgery. Follow the prescribed drops and advice on returning to work, driving, exercise and contact-lens use.
What are the benefits and risks?
For suitable patients, ICL can reduce dependence on glasses while leaving the natural lens in place. It avoids the removal of corneal tissue used in laser correction, but it remains an operation inside the eye.
Potential problems include glare or haloes, raised eye pressure, cataract formation, infection, inflammation and loss of corneal endothelial cells. Further surgery may be needed to reposition, exchange or remove the lens, and serious complications can affect sight.
STAAR, the lens manufacturer, describes the risks in its UK ICL safety information. Your surgeon should explain the risks relevant to your proposed lens and measurements before you decide.
What will ICL treatment cost?
ICL treatment at Precision Vision London starts from £3,650 per eye. The final quotation depends on your prescription, lens and treatment plan.
Before booking, ask the team to confirm the consultation charge and what the treatment price includes. Your quotation should also explain follow-up arrangements and any conditions or charges for additional treatment.

What our ICL patients say
“I had worn glasses for 25+ years and was very short-sighted, so laser was not an option. I had implantable contact lenses done and am thrilled with the results — my vision is now clearer than it ever was with contacts or glasses. I would highly recommend this treatment to family and friends.”
“I was nervous about having ICL, but the professionalism of all the staff helped to relax me. The procedure was far less painful than I had imagined and very quick. The aftercare has been extremely good — I now have 20/20 sight (from approx. -8.00) and I am extremely happy.”
“The treatment and follow-up care have been fantastic. My vision has improved beyond belief and I now have 20/20 vision in both eyes. They even called both evenings after surgery to make sure I was OK. Thank you.”
Questions about implantable lenses
Is ICL better than laser treatment?
There is no single best procedure for every eye. Your prescription, measurements and eye health determine which options are appropriate.
Can the implant be removed?
Removal or exchange is possible through further surgery if clinically appropriate. This should not be understood as a risk-free reversal of the original operation.
Can problems occur with a biocompatible lens?
Yes. Biocompatibility does not remove the possibility of inflammation, pressure changes or other surgical complications. Your surgeon will explain these during consent.
Will I need reading glasses later?
You may. ICL leaves the natural lens in place and does not prevent age-related loss of near focusing. Discuss reading and screen-work expectations before treatment.
What happens if I am not suitable?
Your clinician can explain other appropriate options, including continuing with glasses or contact lenses. You do not have to proceed with surgery.
