[Comparative study of treatment of the dry eye syndrome due to disturbances of the tear film lipid layer with lipid-containing tear substitutes].

Background: A deficiency in the tear film lipid layer is aetiological in about 80 % of the patients suffering from dry eye, which results in excessive evaporation (so-called hyperevaporative dry eye). The treatment with conventional artificial tears did not prove to be successful here. In this study the treatment with two tear substitutes containing lipids were set in contrast with each other.
