What are implantable contact lens?

Implantable contact lenses (ICL) are soft, flexible implants which are similar to traditional contact lenses. They are implanted within the eye between the natural lens and the iris. It’s a bit like having permanent contact lenses that you never have to take out, clean or think about. The implantable contact lens surgery uses Phakic Intraocular Lenses (pIOLs). At Moorfields Private Eye Hospital, we utilise two types of Phakic IOL. These include;

  • Visian Implantable Collamer lens (ICL), which is a soft and flexible implant that sits between the natural lens and iris
  • Artisan intraocular lens (IOL), which sits just in front of the iris

Your consultant will be able to advise you on which option is best for you.”

The benefits of ICL surgery

Implantable contact lenses can be used to treat a wide prescription range to deliver clearer, improved vision without permanent modification of the cornea such as with LASIK,. There is no thinning of the corneal and no risk of laser-induced dry eye.

You cannot see or feel ICLs after implantation, and they do not need to be cleaned. The artificial lens also contains UV protection, which prevents UV rays from affecting the eye and contributing to eye disorders. Another benefit of ICL is that the surgery is reversible and the lens can be removed at any stage, for instance, if cataract surgery is required later in life.

ICL are preferred to refractive lens exchange (cataract surgery) in younger patients because the natural lens is still flexible enough to allow you to read without glasses after correction of your distance vision. It can also help patients who may not be suitable for other types of vision correction treatment.

What does ICL eye surgery involve?

Your eyes will be assessed during the initial consultation and your prescription checked by an optometrist. A full medical history will also be taken to ensure the consultant is aware of any medical conditions that may affect your ability to undergo surgery. Your consultant will then be able to advise you on the most suitable procedure for you, as well as discussing the possible alternatives with you.

At Moorfields Private, your chosen consultant will supervise every stage of your care from start to finish for complete continuity and peace of mind.

During ICL surgery, either both eyes are treated on the same day, or the second operation typically a week after the first. Anaesthetic and sedatives are administered prior to treatment to ensure you experience minimal discomfort. A small keyhole incision (2-3mm) is then made in the edge of the cornea and the ICL is folded and inserted into the eye through this. Using a special delivery device, the lens implant is correctly positioned behind the iris and unfolds into place.

You may experience some side effects after the procedure, such as blurry vision, sensitivity to light, discomfort of the eyes and glare from lights in the dark, but these are only temporary.

If you are driving to your surgery appointment, you will need to arrange someone to drive you home on the day of your procedure. Everyone heals at different speeds and you should not drive until you feel completely comfortable doing so. Recovery time for ICL is fairly short and most patients can see well enough to return to work the day after surgery. You will return for a check-up at Moorfields a few weeks after your surgery.

Why choose Moorfields Private?

Moorfields Private Eye Hospital is renowned for its world-class quality of care. All our surgeons work at the top of their profession and hold accredited consultant positions at Moorfields Eye Hospital NHS Foundation Trust. All consultants who perform ICL surgery are Visian ICL accredited.

When you undergo a vision correction procedure with us your consultant surgeon will supervise you throughout all your visits from start to finish, overseeing every aspect of your care. This ensures you receive a service with complete continuity and feel completely comfortable at each stage.

Your vision is so important and at Moorfields Private, we pride ourselves on delivering an exceptional experience with the best results.

Am I suitable for implantable contact lenses?

ICL is one of the vision correction solutions available at Moorfields Private and is suitable for patients with a very wide range of prescriptions, from low to severe myopia and hyperopia, with or without astigmatism, as well as those who are either not suitable for or reaching the borderlines of laser vision correction suitability. ICL is also considered to be a safer choice than laser eye surgery for anyone with pre-existing cornea or eye surface problems.

It can be a great option for those with high prescriptions, thin corneas, and existing dry eye risk factors or concerns. To give you a guide of the prescriptions that can be treated successfully, we would recommend up to -18.00D for short sightedness, +10.00D for long sightedness and up to + or -4.50D of astigmatism. If your prescription is beyond this, ICL surgery can be followed a few months later with laser treatment to correct any residual focusing issues.

Even though younger patients can be particularly suitable for ICL, you need to be over 21 years old to have the treatment and you also need to have a stable glasses prescription.

If you have other eye problems, such as cataracts, glaucoma or recurrent inflammation, then ICL may not be a suitable option. You will also need an eye scan at your first consultation to check that you have enough room in the front of your eye to fit the ICL safely.

How much does ICL surgery cost?

The initial consultation fee is £195. The full cost of your onward treatment will be confirmed once you have agreed your personalised plan with your consultant.

The price for ICL surgery is £4,079 for one eye or £7,497 for both eyes. This price is inclusive of your consultant’s professional fees, as well as your personalised care plan, detailed diagnostic tests and checks, and two follow up appointments for your aftercare.

There may be circumstances where additional scans/tests are required that are outside the package price. This is rare and your consultant will discuss this with you if any additional tests are required.

What are the ICL risks?

There is a small risk with all forms of eye surgery, and these will be discussed with you in detail at your consultation. However, your chances of having problems are significantly reduced when you put yourself in expert hands and an approved clinical environment. You can rest assured that Moorfields Private Eye Hospital has a well-established safety track record with ICL treatment.

Next steps

The only way to know which vision correction treatment is the right option for you is by booking an appointment with one of our specialist consultant eye surgeons. Here are the next steps to take towards better vision:

  1. Book an appointment with one of our consultants.
  2. After you’ve met with the consultant and are happy to proceed after your “cooling off period”, book a date for surgery.
  3. After your surgery, you can usually return home on the same day.
  4. You can shower from day one, but most surgeons recommend no swimming for a week and no contact sports for a month after the treatment.
  5. Come back for post-surgery check ups and an annual review with your consultant or high-street optometrist
