Phakic IOL Surgery in Northern Ireland

Vision correction for high-prescriptions that keeps your natural lens in place

Phakic IOL Surgery may be suitable for people with higher prescriptions or thinner corneas. It may also be considered if laser eye surgery has been deemed unsuitable for your eyes.

It uses a clear lens implanted inside the eye while keeping your natural lens in place. At Optilase, we assess your eyes and prescription to determine whether a Phakic IOL is appropriate for you.

What is a Phakic IOL?

The word “phakic” means that your natural lens remains inside the eye. A Phakic intraocular lens is an additional artificial lens implanted inside the eye to correct your prescription without removing the natural lens. Depending on the lens design, it may sit in front of or behind the iris, the coloured part of the eye.

A simple way to think about it is as a contact lens placed inside the eye rather than worn on its surface. Once positioned, it does not need to be removed, replaced or cleaned each day.

Phakic IOLs can correct a wide range of prescriptions, including significant myopia (short-sightedness) and, depending on the lens selected, hyperopia (long-sightedness) and astigmatism. This can make them particularly useful when the prescription falls outside the appropriate range for corneal laser treatment. Unlike laser eye surgery, Phakic IOL Surgery does not correct your prescription by permanently reshaping or thinning the cornea.

The lens can be removed if clinically necessary. However, removable does not mean risk-free, and removing an implant cannot guarantee that every complication or change associated with surgery will be reversed.

When laser eye surgery is not an option

A removable lens option for suitable patients who may not be suited to laser vision correction.

Being unsuitable for laser eye surgery does not mean you have no surgical options. A Phakic IOL adds a corrective lens inside the eye while preserving your natural lens and avoiding permanent corneal reshaping. It does require careful selection and ongoing eye-health monitoring, both of which we explain before you decide.

What happens during Phakic IOL Surgery?

Phakic IOL Surgery is generally carried out using local anaesthetic. The lens is inserted through a very small opening at the edge of the cornea and positioned inside the eye while your natural lens remains untouched.

  • 01

    Anaesthetic drops are applied

    Your eye is numbed before surgery using local anaesthetic. You remain awake during the procedure, and your clinical team will explain what is happening and help keep you comfortable throughout.

  • 02

    A small opening is created

    Your surgeon creates a small, precise opening at the edge of the cornea to allow the implant to enter the eye. Some Phakic IOLs need additional preparation beforehand, such as a small laser-created opening in the iris to help fluid circulate normally. This is not required for every lens design, and your surgeon will explain whether it applies to you.

  • 03

    The lens is inserted and positioned

    The Phakic IOL is folded and passed through the small opening using a specialised delivery system. Once inside the eye it unfolds and is carefully positioned in front of or behind the iris, depending on the lens. Your natural lens remains in place.

  • 04

    The opening seals and recovery begins

    The small opening is designed to seal naturally, so stitches are not normally required. Your eye is checked after treatment and you go home the same day with personalised instructions for the early recovery period.

Your Phakic IOL consultation

Phakic IOL Surgery is an intraocular procedure, so detailed measurements and careful suitability screening are particularly important. Your consultation determines whether there is enough space inside your eye to position the implant safely, and whether the treatment suits your prescription and overall eye health. Your assessment may include:

  • A discussion of your current and previous prescriptions
  • Detailed vision testing
  • Examination of your overall eye health
  • Corneal measurements
  • Measurement of the anterior chamber depth
  • Assessment of your natural lens
  • Eye pressure checks
  • Pupil measurements
  • Retinal assessment, particularly where high myopia is present
  • Measurements to determine the appropriate lens size and power
  • Discussion of your work, lifestyle and visual priorities
  • Explanation of the expected recovery period
  • Discussion of short- and long-term risks
  • Explanation of the follow-up and ongoing monitoring recommended after surgery
  • Time to ask questions before deciding whether to proceed

We will confirm your consultation fee when you book. If Phakic IOL Surgery is not compatible with your eyes, our clinical team will explain whether another form of vision correction may be more suitable.

Who is suitable for Phakic IOL Surgery?

Phakic IOLs are often considered for younger adults whose natural lens is still clear and flexible, particularly when their prescription or eye measurements make laser vision correction less appropriate. Preserving the natural lens allows its existing near-focusing ability to remain. You may be considered for treatment if you:

  • Have a stable prescription
  • Have a higher prescription
  • Have thin corneas, which make laser treatment less suitable
  • Have sufficient space inside the eye for the lens implant
  • Have a healthy natural lens without significant cataract
  • Have suitable eye pressure and overall eye health
  • Understand the need for continued eye-health monitoring after treatment
  • Have realistic expectations about the level of vision surgery can provide

You must be over 21 to be considered for treatment. A strong prescription alone does not determine suitability: your individual eye measurements and health determine whether treatment is appropriate.

Benefits of Phakic IOLs

The implant can be removed or exchanged

If clinically necessary, a Phakic IOL can be removed at a later date. It may also be exchanged, for example if a different lens size is required or if another eye procedure becomes necessary in future.

This flexibility is a genuine advantage, although removing the lens does not guarantee that every effect of surgery can be undone.

Phakic IOL recovery and risks

Phakic IOL Surgery is an established form of vision correction, but it is still surgery inside the eye. Understanding the early recovery, possible side effects and need for longer-term monitoring is an important part of deciding whether treatment is right for you.

Recovery and aftercare

Vision often improves within the first few days, although recovery varies. You may temporarily notice blurred or fluctuating vision, light sensitivity, glare or halos.

Our team will give you personalised aftercare instructions, including guidance on eye drops, driving, exercise and returning to normal activities. Follow-up appointments allow us to check how your eyes are healing and monitor the implant.

Long-term eye-health monitoring

Regular eye examinations remain important after Phakic IOL Surgery. These may include checks of your eye pressure, corneal health, implant position, natural lens and retina. The recommended monitoring depends on the type of lens implanted and your individual eye health.

Ongoing checks do not mean a problem is expected. They allow changes to be identified early and managed appropriately if they develop.

Phakic IOL side effects and risks

Possible side effects and risks include:

  • Raised eye pressure
  • Infection or inflammation
  • Glare or halos
  • Under- or over-correction
  • The need to reposition or exchange the implant
  • Earlier cataract development

Different Phakic IOL designs have different risk profiles, so your surgeon will explain the risks relevant to the specific lens recommended for you.

Phakic IOL technology and treatment planning

A Phakic IOL is a small, carefully manufactured artificial lens designed to add the focusing power needed to correct your prescription. Different designs sit in different parts of the eye: some behind the iris and in front of the natural lens, others in front of the iris.

Some Phakic IOLs are available in toric designs, which incorporate correction for astigmatism as well as the main glasses prescription. The most appropriate lens should be selected based on your eye measurements rather than preference alone.

How Phakic IOLs compare

A Phakic IOL is one of several ways to correct a prescription. Which suits you depends on your measurements, not on which procedure sounds most advanced.

    Laser eye surgery reshapes the cornea to correct common vision problems, which can free you from glasses and contact lenses. It takes minutes per eye, and most people see more clearly within days.

    Lens Replacement Surgery

    Lens Replacement and Phakic IOLs work within the eye rather than on its surface. Lens Replacement typically suits ages 40–65 experiencing presbyopia, while Phakic IOLs suit higher prescriptions or thinner corneas not suited to laser.

Phakic IOL questions answered

Quick answers to the questions we hear most often about Phakic IOL Surgery at Optilase.

  • A Phakic IOL is an artificial corrective lens implanted inside the eye without removing your natural lens. It works alongside your natural lens to correct how light focuses and reduce dependence on glasses or contact lenses.

  • Phakic IOL implantation is an established vision correction procedure, but no surgery inside the eye is completely without risk.

    Potential complications include infection, raised eye pressure, inflammation, cataract formation, problems with the implant's position or size and, rarely, significant vision loss. Careful suitability screening and ongoing eye-health checks are therefore important, and your surgeon will explain the risks associated with the specific lens recommended for you.

  • Yes. One benefit of Phakic IOL Surgery is that the implant can be removed if clinically necessary, because your natural lens has not been removed. It can also be removed as part of future cataract surgery if needed later in life.

    Removal should not, however, be described as a guarantee that every complication associated with the original surgery can be reversed.

  • No. With a Phakic IOL, your natural lens remains inside the eye, and an additional corrective lens is implanted alongside it. Lens Replacement Surgery removes the natural lens permanently and replaces it with an artificial lens.

    The two treatments are therefore generally suited to different patient profiles.

  • Laser eye surgery corrects your prescription by reshaping the cornea. Phakic IOL Surgery instead places an additional corrective lens inside the eye and does not permanently reshape or thin the cornea.

    With Phakic IOL Surgery, surgeons can treat higher prescriptions and thinner corneas, in many cases beyond what laser eye surgery can achieve.

  • Potentially, yes. A large pupil does not automatically determine whether you can or cannot have Phakic IOL Surgery.

    Pupil size is one of the measurements considered during your assessment, particularly when discussing the possibility of night-time visual effects such as glare or halos. The decision also depends on your prescription, internal eye dimensions, lens design and overall eye health.

  • Vision often improves considerably during the first few days, but it can initially fluctuate as your eyes recover. You may temporarily notice blur, glare, halos or greater sensitivity to bright lights, particularly at night.

    These effects generally improve over time. Your final result depends on your original prescription, eye health, lens choice and individual response to surgery.

  • Substantial visual recovery often occurs within a few days, although everybody heals at a different rate. Some visual effects, particularly glare or halos, may take longer to settle.

    Your follow-up appointments allow the team to monitor your healing and advise when you can safely return to activities such as driving.
