How is Acanthamoeba keratitis spread?
Acanthamoeba is a microorganism discovered in water, soil, sewage systems, cooling towers, and heating/ventilation/air conditioning (HVAC) systems. Acanthamoeba keratitis (AK) is a rare, but serious, infection of the cornea. AK is most commonly suffered by individuals who improperly store/handle/disinfect their lenses (e.g., use tap water or homemade solutions for cleaning), swim/use hot tubs/shower while wearing lenses, come in contact with contaminated water, have minor damage to their corneas, or have previous corneal trauma.
