Modern corneal refractive surgery provides high efficiency, safety, predictability and stability of the different ametropia kinds correction’s clinically-functional results. However, in overwhelming percentage of cases, having spent some time after surgery patients complain about discomfort, eyes dryness, burning, feel gritty, redness, blurred and vision instability. Complaints mentioned above are caused by the appearance of transitory dry eye syndrome. Main etiology and pathogenesis factors of this disease are presented in this review. The results of dry eye syndrome classical diagnosis methods have been analyzed, as well as modern techniques, characterized by high specificity and sensitivity, which allow to increase the dry eye’s diagnostics accuracy. The study of the dry syndrome after corneal refractive surgery is devoted to a huge number of works of domestic and foreign authors. However, at present time there is no unique algorithm for assessing the damage of the ocular surface before and after corneal refractive surgery, which would include a set of high-precision and specific techniques for quickly and reliably evaluate the severity of dry eye syndrome, allowing to develop preventive measures and pathogenetically oriented treatment and, thereby, accelerate rehabilitation of patients after surgery. Research continuation is needed in this direction.
