Everything you need to know

Lens implantation - see clearly with artificial lenses

Lens implantation is a lesser well-known but effective treatment that enables clients to see without aids. It's the perfect solution when your eyes are not suitable for laser eye surgery, but you want to stop using glasses or contact lenses or stop having difficulty reading.
An advanced artificial lens in your eye corrects your visual defects: whether near vision, distance vision or poor vision. An implanted lens can even remove cataracts. The results are highly predictable. Wonderfully clear vision.

Essential first step

The preliminary examination

The first, essential step to identify what condition your eyes are in. Treatment will not be possible without a preliminary examination. The preliminary examination is always free of charge and without obligation. It includes eye tests, your consultation with the eye specialist who will also perform the treatment on you and a tailor-made treatment recommendation. Even if you decide not to have any treatment. Or if your eyes can't be treated because of contraindications.

Is a particular treatment right for you?
This will depend on:

  • the size of your pupil
  • the thickness of your cornea
  • how you use your eyes in your day-to-day life

What is lens implantation?

Lens implantation literally involves the implantation of an artificial lens in your eye. Two types of treatment are possible. Implantation in front of your natural eye lens or the replacement of your own eye lens. To give you visual freedom for the rest of your life.

Clear vision
Back in the Second World War, a famous eye specialist developed the first artificial lenses. His discovery led to the development of refractive lens implantation. Besides laser eye surgery, in which the shape of the cornea is changed, implanted lenses are an alternative way of restoring clear vision.

Side effects and complications

The risks of lens implantation

No operation is risk-free. Not even lens implantation surgery. Although the risks are very small, complications can happen.

Possible complications of lens implantation


  • Wound leakage
  • Infection


  • Increased eye pressure
  • An increased risk of developing cataracts


  • Stimulation of the retina
  • Retinal detachment
  • Ruptured lens capsule

Possible side effects of lens implantation


  • Residual strength


  • Spots or opacities
  • Perceiving blue-tinged colours
  • Auras and haloes
  • Secondary cataracts

Can a lens implantation treatment make you go blind?

There is just a very small risk of going blind after a treatment. It’s never happened at FYEO yet.

Like any other medical intervention, the treatments provided by FYEO involve some degree of risk. In theory, a complication (which often happens if someone doesn’t follow medical advice or is careless with instructions and medication) can lead to blindness. The chance of this happening is extremely small if you carefully follow all the instructions provided. Also, the complications described above are often easy to treat.

Types of lens implantation
2 methods

Types of lens implantation

There are different types of implanted lenses. Each lens corrects a different vision imperfection. Your age and eye health determine which lens implantation is right for you. An implanted lens can be implanted as an intraocular lens  in front of your natural eye lens or replace your natural eye lens.

Additional lens

A lens that is implanted in front of your natural eye lens

You keep your natural eye lens. The implanted lens does not change your eye structure. You gain another lens. Implanted right in front of your own eye lens. Additional lenses are transparent, high-quality and will stay firmly implanted in your eye for the rest of your life. Unless you need another eye treatment.

Replacement lens

A replacement for your natural eye lens

Freedom and happiness are both guaranteed. A permanent lens that replaces your natural eye lens. This is an excellent treatment, because these lenses give you razor-sharp vision for the rest of your life. The total solution for your eyes.


A versatile alternative to laser eye surgery. A type of contact lens that’s implanted in your eye, not on your eye. ExtraLenses are suitable for clients between the ages of 18 and 50.


ReplaceLenses are customised implanted lenses that replace your natural eye lens. They’re ideal if you're under 45 and don’t want to wear glasses or contact lenses.

Low Vision Lens

A special lens developed to correct low vision. The Low Vision Lens is implanted in 1 eye. See it as a magnifying glass in your eye that enables you to see clearly at short distances again.

Readon ReplaceLens

The Readon ReplaceLens replaces the natural eye lens in 1 eye. The lens corrects your near- and farsightedness vision for the rest of your life. You won’t ever develop cataracts in the treated eye either.

Recovery after lens implantation

Very fast recovery. Replacing the lens is a minimal procedure. The biggest challenge is getting used to your new vision. How quickly you recover after a lens implant treatment will depend on the artificial lens used. The recovery period for ExtraLenses is very short. You will regain razor-sharp vision without any after-effects. It takes slightly longer for the brain to adjust to ReplaceLenses and the Low Vision Lens.
In general, time, rest, instructions and eye medication are the best healers. The aftercare will last as long as you continue to have check-ups. This will be a minimum of 3 months after your treatment.

Your responsibility

Instructions to follow after lens implantation

It’s important to follow your eye specialist’s instructions at all times. This will help prevent complications and promote your recovery. Several general tips:

  • If you are up to it, you can resume your normal daily activities the day after the treatment. Avoid exerting yourself too much for a week after the treatment;
  • Be careful if playing contact and ball sports. Our advice is to avoid contact and ball sports for up to 4 weeks;
  • The golden rule is to keep water out of your eyes for up to 2 weeks after your treatment;
  • Touch your eyes as little as possible for the first month. Don’t rub your eyes in the first 4 weeks;
  • You can start wearing eye make-up again 2 weeks after the treatment.

The full range of artificial lenses and their specifications follow below. It doesn’t get any more convenient than that.
Having all the information you need will help you to make the right choice. You'll finalize your decision on which lens implant is right for you with your eye specialist.

Customised artificial lenses

Would implanted lenses be right for me?

We have all the lenses necessary to resolve clients’ eye conditions. The most important question will always be which type of artificial lens is right for you?
You need the treatment that's personally appropriate for you. Lens implantations resolve many eye problems. Even more than laser eye surgery does. Implanted lenses are ideal if you have difficulty reading, low vision, high deviations in strength or an eye condition like cataracts.

Your age will sometimes be the only reason for you to have to put off having a treatment for a while. But when you’ve reached the minimum age specified, you’ll be able to go ahead and have the appropriate lenses implanted.
