The article offers insights on the prevention, diagnosis and treatment of Acanthamoeba keratitis (AK) infections from contact lenses. The signs and symptoms of AK include a raised branching pattern and a white spot that looks like a bull's eye lesion in the epithelium. Clinicians are advised to suspect AK infection if a patient has a nonspecific keratitis that does not respond well to therapy. Patients should be treated with topical polyhexamethylene biguanide (PHMB) 0.02% for 2 days every hour, alternating on the half hour with propamidine isethionate.
