Summary: Allergy is a state of immunologically mediated hypersensitivity to a foreign substance. For patients with refraction errors contact lenses have become a comfortable and extremely popular alternative to glasses. Due to advances in manufacturing technologies, a comprehensive assortment of market contact lenses is now available. Although the number of contact lens wearers increases, complication rates go down. The paper presents several issues related to corneal response to contact lenses – among them the incidence of adverse reactions and complications resulting from mechanical irritation, unstable tear film, metabolic disturbances, and inflammatory as well as toxic-allergic reactions. Corneal lesions may develop in any of its layers. Allergic reaction to hypoxia and contact lenses care solutions most often results in superior limbic keratoconjunctivitis. A reaction to preservatives may cause superficial punctate keratitis. However, allergy to contact lenses most frequently presents as giant papillary conjunctivitis, which is an iatrogenic allergic-mechanical disease.
Keywords: allergy, contact lenses, keratitis, giant paplillary conjunctivitis.
