The probability of dry eye syndrome (DES) in the patients using the Silicone-Hydrogel Contact Lenses is examined in many researches. Therefore, adhering to clinical recommendations is an important factor for DES prevention. The urgent issue is also a comprehensive assessment of functional parameters as pathogenetic base of DES.The objective of the research was tostudy DES development depending on compliance of silicone hydrogel contact lenses users.Matherials and methods. 97 patients (194 eyes) were included into the research. They formed 2 groups: group I with incomplete compliance (36 persons) and group II with complete compliance (61 persons). All the patients underwent the Norn’s test, Schirmer’s test, Jones test, tear film stability was defined. The probability of the dry eye syndrome development due to the subjective signs was also analysed.Results. The reliable decrease in the total (р<0.05) and basale lacrimation (р<0.05) indexes, the increase in osmolarity (р<0.05) and decrease in tear film stability (р<0.05) were detected in the patients who did not follow the clinical guidance during the Silicone-Hydrogel Contact Lenses wearing. In the same group the higher risk of dry eye syndrome development was verified (р<0.05).Conclusion. Compliance disorder in the patients using Silicone-Hydrogel Contact Lenses was found to induce the reliable decrease in total and basale lacrimation, increase in osmolarity and tear stability disorder. All of this factors increase the risk of dry eye syndrome.
