Contact Lens Wearers at Risk of Eye-eating Amoeba

Contact lenses have always raised ENT experts' eyebrows. Here is yet another discovery that has caused them to question the integrity of soft, rigid or hybrid lenses.

University of Aberdeen professors issued a warning to contact lens wearers, of an eye-eating amoeba that can infect ones who do not clean their lenses on a regular basis. Acanthamoeba takes a week to penetrate within cornea to cause scarring and further leading to cloudy vision.

It is a potent concern for over 125 million contact lens wearers worldwide, though its incidence is rare. It could be treated if diagnosed early with disinfecting eye drops. If eye drops dosage fails to work, patient may require a corneal transplant. In cases where organism gets embedded deep in eye tissues, blindness may be a consequence.

The safest option to rule out the risk from acanthamoeba is single use daily contact lenses. An infection can manifest when contact lenses are rinsed out with tap water, while some users may pick up microorganism unknowingly during swimming or showering.

Health experts recommended lens wearers to clean their lens cases once in 5 days for ensuring eye health and keeping the bug away.
