Artificial tears are lubricating eye drops used to relieve dryness and irritation of the ocular surface.[1] Dry eye syndrome (keratoconjunctivitis sicca) is a common ocular surface disorder and is characterized by disruption of the tear film and increased inflammation.[2]
The tear film coats the surface of the eye and is composed of 3 layers: an aqueous, lipid, and mucous layer.[3] The aqueous layer consists of a mixture of electrolytes, enzymes, antibodies, antimicrobial proteins, and other compounds.[3] The lipid layer consists of fatty compounds that are responsible for decreasing evaporation of the tear film.[3] The mucous layer contains mucins, gelatinous glycoproteins, which allow for an even distribution of the tear film over the corneal surface and decreased friction during blinking.[3]
Artificial tears are used to supplement a patient's naturally-produced tears and increase eye lubrication by mimicking characteristics of the tear film.[4] Artificial tears can be supplemented with other treatments to treat dry eye syndrome and are available over the counter.[5] Artificial tears are also used to moisten contact lenses and in eye examinations.
