The Serious Threat of Acanthamoeba Keratitis: Key Takeaways and Safety Tips
Understanding Acanthamoeba Keratitis
Acanthamoeba keratitis is a life-altering eye infection caused by a microscopic parasite found in water, including tap water. When contact lenses are worn during water activities or left overnight, the risk of infection increases dramatically. This infection can lead to agonizing eye problems and even blindness if not treated promptly.
The Risks of Swimming or Showering with Contacts
Many people mistakenly believe that showering or swimming with contact lenses won’t harm them. However, this is far from the truth. The tiny tears created by the contact lenses on the cornea allow Acanthamoeba to enter, multiply, and cause severe symptoms such as:
- Eye pain
- Redness
- Blurred vision
- Sensitivity to light
- Watery eyes
Swimming or showering with contact lenses can significantly increase the risk of infection, as seen in the cases of Nina Wang and Emily Kelleher.
The Real Stories: From Bali to Massachusetts
-
Nina Wang: A businesswoman from London contracted the parasite while on holiday in Bali. She initially brushed off her symptoms as mild conjunctivitis and continued wearing her contacts, which led to a severe infection. Nina eventually underwent laser eye surgery to regain most of her vision.
-
Emily Kelleher: A high school English teacher from Massachusetts experienced pain when the parasites entered her eye while showering with contacts. Her case highlights the importance of recognizing symptoms early and seeking immediate medical help.
- Brooklyn McCasland: A Texas barista lost all vision in her right eye due to Acanthamoeba keratitis. She was initially misdiagnosed and treated for sand in her eye, but the parasitic infection progressed and caused permanent damage.
Safe Contact Lens Practices: Prevention is Key
To avoid Acanthamoeba keratitis, follow these essential guidelines:
- Never swim, shower, or bathe with contact lenses.
- Always remove your lenses before sleeping.
- Maintain a strict lens care routine, including appropriate cleaning and storage.
- Use new lens cases every 2 to 3 months.
- Never reuse solution in contact lens cases or containers.
Expert Advice: The Risks of Soft and Extended-Wear Lenses
Opticians and ophthalmologists emphasize that soft contact lenses, due to their high water content, are the most prone to Acanthamoeba keratitis. Extended-wear lenses, often worn overnight, can create an environment where microorganisms such as Acanthamoeba can thrive and cause infections.
Professional Treatment and Recovery
If you suspect you have Acanthamoeba keratitis, seek medical help immediately. Early treatment with eyedrops can often clear the infection. However, in more severe cases, patients may need laser surgery or corneal transplants, as seen in Nina Wang’s story.
Call-to-Action
Remember, contact lenses are a convenience but come with significant risks. Ensure you understand these risks and follow proper guidelines to protect your eye health. Always consult your optician or ophthalmologist if you experience unusual symptoms or have concerns about your eye health.
