Can an intraocular lens be removed and replaced?

Yes, in most cases, an intraocular lens (IOL) can be removed and replaced. But it’s not something that’s done often—and there’s a good reason why.

Let’s explain why someone might need to have a lens exchanged, how the procedure works, and what to expect if this happens.

First, what is an intraocular lens?

An intraocular lens (IOL) is the clear, artificial lens that’s implanted in your eye during cataract surgery or lens replacement surgery. It sits inside the eye, where your natural lens used to be.

IOLs are made from medical-grade materials like acrylic or silicone. They are designed to last a lifetime. In the vast majority of cases, they do.

Why would someone want to replace their lens?

Although it’s uncommon, there are situations where a lens may need to be replaced:

• The lens power isn’t quite right: In rare cases, the lens doesn’t correct your vision as expected. This could be due to healing differences or an unusual eye shape.
• Visual side effects: Some people experience glare, haloes, or night vision disturbances with certain types of lenses, like multifocal IOLs.
• Lens dislocation: Very rarely, the lens may move out of place inside the eye and need to be repositioned or replaced.
• Change in vision needs: A person’s vision needs may change with age, and they may want a different lens type later.

How common is this?

At Mitry Vision, lens exchange is extremely rare. We use detailed pre-operative scans and thorough consultations to plan your surgery precisely. This greatly reduces the chance of dissatisfaction after surgery.

What is the lens exchange procedure like?

Lens exchange is similar to the original lens surgery. Your surgeon will make a small incision in the eye and gently remove the existing IOL. A new one is then placed into the same position.

It’s more complex than the first procedure, especially if it’s been a long time since the original surgery. Scar tissue may have developed. That’s why this surgery should only be done by a highly experienced eye surgeon.

What should I do if I’m not happy with my vision?

If you've had lens surgery elsewhere and something doesn’t feel right—don’t panic. It may be something simple, like dry eyes or a cloudy lens capsule. Or you may just need more time to adapt.

Our advice: come in for a consultation. We’ll take a close look, explain your options, and help you decide what’s best for your eyes and your goals.
