Considering vision correction but not sure laser eye surgery is right for you? Implantable Contact Lens (ICL) surgery is a safe, effective alternative that can help you enjoy sharp, clear vision – without the need for glasses or traditional contact lenses. At Oculase, our leading ophthalmologists offer personalised care and advanced ICL treatment options tailored to your eyes and lifestyle.
Here, we explain how ICL surgery works, who it’s suitable for, what to expect before and after treatment, and the benefits it can offer.
What is an implantable contact lens (ICL)?
Implantable Contact Lens, also known as Implantable Collamer Lens (ICL), gives you sharp, clear vision without needing glasses or traditional contact lenses.
This ICL lens sits in the space in front of your natural crystalline lens (behind the coloured part of your eye, known as your iris), allowing you to see clearly and sharply without any glasses or contact lenses.
Unlike traditional contact lenses, the ICL lens can remain in the eye permanently, is not visible to the naked eye, and does not have to be removed or cleaned.
Learn more about contact lens use on our blog, ‘Contact Lens: Risks, Side-effects & Alternatives’.
Is an ICL the same as a permanent contact lens?
Yes and no! An implantable contact lens is intended to be a long-term solution for vision correction. Once implanted, it remains securely in place inside the eye and does not require daily removal or cleaning like traditional contact lenses. However, while it’s designed to stay in place indefinitely, the ICL can be safely removed or replaced by our eye surgeons if necessary – offering both stability and flexibility over time.

What happens during ICL surgery?
During ICL surgery, we implant a specially designed custom refractive lens in the eye through a tiny self-healing incision.
Our video below – How is Implantable Contact Lens (ICL) surgery performed? – covers how we perform ICL surgery.
The procedure takes between 20 and 30 minutes per eye, after which you have a permanent lens implant.
However, the procedure is reversible, and we can remove the lens implant if appropriate, for example, if you need cataract surgery later in life or if you have a major prescription change. This offers you peace of mind and flexibility for the future.
How much does ICL surgery cost?
At Oculase, we believe in making high-quality vision correction accessible and transparent. That’s why we offer FREE video consultations to discuss whether ICL surgery is right for you.
The price of implantable contact lens surgery at Oculase starts from £2,950 per eye, depending on your individual prescription and clinical needs. This includes comprehensive pre-operative assessments and expert care from our leading ophthalmologists.

I basically grew up wearing glasses, quite thick ones, because I’ve been highly myopic since birth and I’ve always wanted to live a glasses-free life. So ICL surgery was the best option. The surgery was a little bit unnerving, but at the same time exciting. I had opted for the local anaesthetic option so I was fully awake although my vision was extremely blurred. But the calming music in the operating theatre definitely helped a lot. The care I received was excellent. The whole team made me feel very relaxed. I felt like the recovery could be broken down into kind of two phases. There was a daytime phase that had a very quick recovery and a nighttime phase, which was a little bit slower. So a few days after the surgery, my daytime vision was superb. I was able to see without any visual aid at all. The ICL surgery has definitely changed quite a bit about my daily lifestyle and activities. I can exercise without any worry about glasses falling off. I can play contact sports, even just cricket without worrying about would I be able to make it back home if I break my glasses. I would highly recommend Mr Ayoub and Oculase for anyone considering any corrective surgery or anything to do with your eyes. I feel Mr Ayoub is extremely professional and so is the team. They’re very empathetic, very caring. They look after you extremely well.

Implantable contact lenses, as the name suggests, is a specially designed lens that sits inside your eye to correct very high prescriptions. It is a very soft synthetic lens that sits behind your iris, which is the coloured bit of your eye, but on top of your natural crystalline lens. As it is inside the eye, it is not visible to anyone around you, and you do not have to take it out and remove it and replace it as you would for a standard contact lens. Those who are not suitable for laser eye surgery would be suitable for implantable contact lenses.

Anyone who has a prescription, whether that’d be myopia or hyperopia or astigmatism, is suitable for implantable contact lens surgery. In general, however, we reserve implantable contact lens surgery for anyone who was not suitable for laser eye surgery. Usually, people who are not suitable for eye surgery have very thin corneas or extremely high prescription, and therefore implantable contact lens surgery would be a better option for them. Additionally, in some people who have had corneal transplants previously, or have stable keratoconus, an implantable contact lens may be a more suitable option.

Implantable contact lens surgery is painless as I use lots of anaesthetic drops to completely numb your eye. In some people I would consider also giving you a block of anaesthetic to freeze your eyes, so you feel no pain. In very rare cases, we can use sedation or general anaesthesia for the surgery, but this usually is not required. The surgery itself is very safe, and very quick, and pain is not usually an issue.

Implantable contact lens surgery is generally a safe procedure with over 1 million of these implanted worldwide. However, there are some important side effects or risks that you need to be aware of. Immediately after the surgery your eyes are going to be sore and red and gritty and you might notice that your vision is slightly blurred. This is normal and resolves over a period of a few days to a couple of weeks with the drops that you will be prescribed. Sometimes after the surgery your pressure may be raised. If this is the case they will give you some drops or tablets to reduce the pressure in your eye. Another important risk of ICL surgery is the issue with sizing of the contact lens. We take several measurements of your eye to predict the exact size of the lens that needs to be implanted in your eye. Usually this lens implant is bespoke to your eye. However, sometimes the lens may not sit snugly in your eye and may rotate or move from its position. In these situations we may have to do a second surgery to reposition the lens, replace it, or remove it. A finally important risk is that one can develop a severe infection which could adversely affect your vision. However, we are able to treat this with antibiotics in most cases.
Am I suitable for ICL surgery?
Almost all prescriptions and eyes can be treated with ICL surgery, so long as there is enough space in the eye to safely fit the ICL lens. This ranges from very low to very high prescriptions.
If you aren’t deemed suitable for laser vision correction (such as if you have a very high prescription, your corneas are too thin, or you suffer from dry eye issues or another eye surface condition), then ICL surgery may be the very best option for you. Other factors also influence whether you are suitable, such as the space available in the front part of your eye.
ICL surgery may be the most appropriate vision correction procedure for you if you have:
- A very high prescription
- Stable keratoconus
- Thin corneas
- Dry eyes
- Other minor corneal problems
Suitability for ICL surgery is also dependent on your:
- Age <45 (ICL is indicated up to 65 years old)
- Lifestyle
- Eye examination
- Work and hobbies
- Consultation eye scan results
During your consultation, Mr Ayoub will discuss whether this or an alternate procedure is suitable for you, depending on your circumstances.
The range of spectacle prescriptions that can be treated effectively with ICL surgery is approximately:
- Up to -20.00D of myopia or short-sightedness
- Up to +10.00D of hyperopia or long-sightedness
- Up to ±6.00D of astigmatism
What are the benefits of ICL surgery?
ICL surgery has several advantages over other types of refractive surgery. It can provide you with a sharp, clear vision and offer you freedom from glasses and contact lenses.
Some further benefits include:
- Fast recovery time – around a few days
- Excellent night vision
- Quick and pain-free procedure
- UV protection
- No dry eye syndrome
- No removal of any natural tissue
- Biocompatible – made with collagen
- We can remove ICL implants
Results show that patients achieve excellent vision during the day and night after ICL. It doesn’t worsen dry eyes, and ICL implants are removable, providing you with future flexibility and peace of mind. Find out more about how long implantable contact lenses last in our blog here.

Are there any risks with ICL surgery?
During your consultation, we will discuss all ICL surgery risks with you and how likely they are. Implantable contact lens surgery is safe and effective and the likelihood of complications is rare.
Mr Ayoub discusses ICL surgery risks in more detail and how we counter these complications at Oculase in our video, What are the risks of Implantable Contact Lens surgery?
Is ICL surgery painful?
ICL surgery shouldn’t be painful. Before the procedure begins, we use anaesthetic eye drops to completely numb the surface of your eye, so you won’t feel any pain during the surgery. You may feel slight pressure or a sensation of movement, but the procedure itself is quick and comfortable.
After surgery, it’s normal to experience mild discomfort, light sensitivity, or a gritty feeling in the eye for a day or two. These symptoms usually settle quickly with the help of prescribed eye drops and rest. Our team at Oculase will guide you through every step of the recovery process to ensure you’re comfortable and supported.
How long does it take to recover from ICL surgery?
Recovery after ICL surgery is typically quick and straightforward. Most patients notice a significant improvement in their vision within 24 to 48 hours. You’ll usually be able to return to work and most of your normal activities within a few days, although we recommend avoiding strenuous exercise and swimming for a couple of weeks. Your eyes may feel slightly sensitive or dry in the first few days, but this usually settles quickly.
Our team at Oculase will provide full aftercare guidance and support throughout your recovery, helping you get the most from your ICL surgery.
