Contact Lens User

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 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.’

Showering, bathing, swimming in pools, lakes, ponds, and oceans with your contact lenses in – and rinsing contact lenses or even cases with tap water – can put you at risk.

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

Always have your routine eye exams and use official products. 

If you suspect that you might have AK, it is important to seek medical attention right away.

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
  • Headache
  • 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!

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.
