Physical Model of a "Dry Eye" Syndrome Pathogenesis, Connected with the Soft Contact Lenses
Aim of investigation is establishment of a «dry eye» syndrome (DES) pathogenesis mechanism, connected with the soft contact lenses (SCL), on a basis of a physical model elaboration.
Materials and Methods. 102 humans (204 eyes) at the age of 18 to 38 years were examined on a presence of a ″dry eye″ syndrome (DES). 55 humans with the soft contact lenses (SCL) were included into the first group; 28 humans without a contact visual correction were included into the second one (a control group).
Results. It is established, that the DES clinical signs are statistically significantly frequently encountered in humans with the SCL compared to those who uses no contact visual correction. A physical model of a contact lens influence is counted on a precorneal lacrimal film. It is revealed, that a lens forms a pressure change dysbalance due to the resistance effects to a flow in a lacrimal film.
