The use of artificial tears is related with dry eye problems or ocular irritations. It exist different types of artificial tears. One type of them is the lipid artificial tears which tray to repair or improve the lipid layer present in the outermostpart of the tear film. Several lipid artificial tears are present in the market and commercialised by several companies. In the composition of some of these lipid tears occurs as a principal item a phospholipid component that is lecithin of soya, which is composed mainly by phospholipids as phosphocholine or also named phosphatidylcholine (PC). The film formation on the water/air interface (Langmuir film technique) has been applied to study the behaviour of Meibomian lipids. The Langmuir technique has been applied previously by the author to study the behaviour of lipid and phospholipid films. In this work Langmuir films have been performed from lipid artificial tears and the corresponding surface pressure-area isotherms registered. Three commercial lipid artificial tears, and presented in dispensers for spray applications, have been used, INNOXA, OPTICALM and OPTREX.
