Acanthamoeba spp. are ubiquitous free-living amoebae that are commonly found in environment. It may cause keratitis in individual using contaminated contact lens or having history of ocular trauma. Seventy-four samples of corneal scrapings from keratitis patients, from 4 hospitals in Klang Valley were cultured for the isolation of Acanthamoeba. Acanthamoeba spp. were successfully isolated from 14.87% of corneal scraping samples from keratitis patients. This study showed that all of the Acanthamoeba keratitis patients were contact lens wearers majority of whom were women (90.9%). Soft contact lens were implicated in 90.9% of cases while the rigid gas permeable type in only one case (9.1%). All 11 Acanthamoeba isolates were from the polyphagids group which were known to be pathogenic to human. Failure of contact lens users to practice good hygienic care of their lenses attributed to the risk factor for the occurrence of Acanthamoeba keratitis in Malaysia.
