The incidence of Acanthamoeba Keratitis is increasing amongst contact lens users.

Contact lenses are medical devices and extra care is necessary to ensure you can enjoy your contact lenses and have happy, healthy eyes.

AK is caused by a free-living amoeba (parasite) that is typically found in soil, bodies of water and even tap water. For the contact lens wearer this presents a risk, as the parasite can get trapped between the eye and the contact lens, creating a viable ‘breeding site.’

Educate yourself
on what you can
and cannot do
with your
contact lenses.


All of the following can put you at risk: wearing your contacts while showering, bathing or swimming in pools, lakes or the ocean; using tap water to rinse your contact lenses or the case; gardening or taking part in other outdoor activities which might lead to soil entering your eye.

If you are a contact lens wearer experiencing any symptoms that could indicate AK, seek medical attention immediately.

It is essential to inform your doctor of your contact lens use, including any activities involving contact with water or soil. It is crucial that you ask your doctor to rule out AK before starting any medication, particularly corticoids or steroids.

You may experience several of these symptoms:

Eye pain (which can be excruciating – but may be painless in the early stages)
Red eyes
Sensation of something in the eye – foreign body sensation
Blurred, poor vision or total vision loss
Sensitivity to light from mild to extremely high
Excessive tear production
Irritation or grittiness
Inability to wear contact lenses

Here are some steps you can take:

Do not wait!
Stop wearing contact lenses.
Consult an eye doctor as soon as possible.
Let them know if you are a contact lens user and have been in contact with water.
Take the contact lenses, casing, and solution with you for possible analysis.
If available, advocate for an early confocal scan to confirm the diagnosis. Time is of the essence!

As a contact lens user make sure you are prepared for any eye problems by finding an eye clinic with a good reputation in your area in case of unexpected problems.

By following the do’s and don’ts, you can help ensure that your contact lens wearing experience is a positive one. If you ever experience discomfort or notice any changes in your vision, be sure to contact your optometrist right away.

Remember, taking care of your contact lenses and protecting your eyes from water exposure is essential for maintaining good eye health and vision.
