Understanding Implantable Contact Lenses Before Choosing Surgery

Implantable contact lenses, commonly known as ICLs, are an advanced form of refractive eye surgery designed to correct vision without reshaping the cornea. Instead of using a laser to alter the front surface of the eye, this procedure places a small prescription lens inside the eye, positioned behind the iris and in front of the natural lens. This approach makes implantable contact lenses an excellent option for people who are not suitable for laser eye surgery, as well as those seeking an alternative method of vision correction.
 
At Centre for Sight, implantable contact lenses form part of a personalised vision correction pathway. Each patient undergoes detailed diagnostic testing and a one to one consultation with a specialist surgeon to determine whether ICL surgery is the safest and most effective option for their eyes and visual goals.
 
Implantable contact lenses are designed to remain in the eye long term, but they are also removable if required. This reversibility provides reassurance for many patients who want a permanent solution that still offers flexibility in the future.

How Implantable Contact Lenses Work Inside the Eye

Implantable contact lenses function differently from traditional contact lenses that sit on the surface of the eye. An ICL is placed inside the eye, where it works alongside the natural lens to focus light precisely onto the retina. The lens corrects refractive errors by adjusting how light enters the eye, resulting in clearer and sharper vision.
 
Because the cornea is not reshaped or thinned, the eye’s natural structure remains largely untouched. This makes ICL surgery particularly suitable for people with thin corneas or high prescriptions, where laser procedures may not be recommended. The lenses are made from a biocompatible material called collamer, which is soft, flexible and designed to integrate safely with the eye’s internal environment.

What Vision Problems Implantable Contact Lenses Can Correct?

Implantable contact lenses are used to correct short sightedness, long sightedness and astigmatism. They are especially effective for moderate to high prescriptions and can provide excellent visual clarity even in cases where glasses or standard contact lenses offer limited quality of vision.

Short Sightedness

Long Sightedness

Astigmatism

For many patients, ICLs deliver sharper contrast sensitivity and improved night vision compared with other forms of correction. Outcomes depend on individual eye characteristics, which is why comprehensive pre operative testing is essential.

Who Is Suitable for Implantable Contact Lenses

Most patients considering implantable contact lenses are over the age of 21 and have had a stable prescription for at least twelve months. Good general eye health is also required. During assessment, specialists examine corneal thickness, anterior chamber depth, pupil size, eye pressure and retinal health to ensure the procedure can be carried out safely.
 
Patients who are not suitable for laser eye surgery due to thin corneas, high prescriptions or corneal irregularities are often excellent candidates for ICLs. If implantable contact lenses are not appropriate, alternative vision correction options will be discussed.

Implantable Contact Lenses vs Laser Eye Surgery

Both implantable contact lenses and laser eye surgery aim to reduce or eliminate the need for glasses or contact lenses, but they achieve this in different ways. Laser procedures permanently reshape the cornea to change how light is focused. Implantable contact lenses do not alter the cornea. Instead, they add an internal lens to refine focus.
 
One of the key advantages of ICL surgery is reversibility. The lens can be removed or replaced if necessary, whereas laser surgery cannot be undone.
 
Implantable contact lenses also tend to be better suited to higher prescriptions and may provide more predictable outcomes in these cases.
The most appropriate option depends on your eyes, prescription and lifestyle, which is why expert guidance is essential.

The Implantable Contact Lens Procedure

Implantable contact lens surgery is performed as a day case procedure using local anaesthetic eye drops. Patients remain awake but comfortable throughout. The surgeon creates a very small opening at the edge of the cornea and gently inserts the folded lens into the eye. Once inside, the lens unfolds and is positioned behind the iris.
 
The procedure typically takes around twenty to thirty minutes for both eyes. Because the incision is extremely small, stitches are rarely required. Most patients describe the experience as straightforward, with little discomfort.
Recovery and Healing After Surgery
Recovery following implantable contact lens surgery is usually rapid. Many patients notice improved vision within a few hours, although vision may fluctuate slightly during the first few days. Mild light sensitivity, dryness or a gritty sensation are common in the early stages and usually settle quickly.
You will be prescribed eye drops to prevent infection and reduce inflammation. Follow up appointments allow your surgeon to monitor healing and ensure the lens is positioned correctly. Most people return to work within a few days, depending on their occupation.
Implantable contact lenses are known for delivering excellent quality of vision. The majority of patients achieve significant reduction in dependence on glasses or contact lenses, and many no longer need them for everyday activities.
The lenses are designed to last a lifetime and do not degrade. If cataracts develop later in life, the implantable contact lens can be removed during cataract surgery and replaced with an appropriate intraocular lens.
Implantable contact lens surgery has a strong safety record when performed by experienced surgeons. However, as with any surgical procedure, there are potential risks. These may include infection, inflammation, raised eye pressure, glare or halos, and in rare cases cataract formation.
Careful patient selection, modern diagnostic technology and thorough aftercare significantly reduce these risks. Your surgeon will explain all potential complications in detail during consultation.

Lifestyle Benefits of Implantable Contact Lenses

For many people, the greatest benefit of implantable contact lenses is freedom from glasses and daily contact lenses. Activities such as sport, swimming, travel and driving become simpler and more convenient.
 
Because the cornea remains untouched, the optical quality achieved with ICLs is often described as crisp and natural, which can be particularly valuable for those who rely on high quality vision for work or hobbies.

Absolutely life changing! I was only 20 when I got this done but having had a stable prescription I knew the time was right. Everyone is so welcoming from the moment you step in. I had a few options but Mr Daya directed me in the right way on which procedure suited me. Me being me I was nervous and they reassured me by giving me a lady’s number who had had the same procedure so I got to have a chat with her about all my worry’s. On the day it’s so straight forward and quick and within hours I could see better. Fast forward over a year I have better than 20:20 vision after previously being -8 my whole life, it is hands down the best thing I have ever done I wouldn’t second think getting it done, thank you so so much.
