| Resumo: | The tear flm has an important role on the quality of the vision process and is of importance in the felds of ophthalmology and optometry. The lipid layer, the outermost part of the tear flm, can be investigated with the Langmuir technique, as well as the interaction of components of the aqueous part of the tear flm with those of the lipid layer. Dysfunctions in the stability and composition of the tear flm are the causes of eye diseases, as the dry eye syndrome. For the treatment of this disease, the artifcial tears are used, and one type of them are the lipid tears, which can be investigated with the Langmuir technique. This technique can also be used to investigate the infuence on the lipid layer of other artifcial tear components or medicines instilled in the eye. This review presents investigations where the Langmuir technique has been used in relation with the tear flm. In particular, the surface properties of natural tears and of four commercial lipid-containing artifcial tears have been reported and discussed in connection with their composition. |
