The use of tear substitutes when wearing contact lenses (literature review)

Topicality. In recent years, dry eye syndrome has become increasingly important in clinical practice. Disturbance of the wettability of the eye surface occurs due to external factors influence, one of which are contact lenses. The review presents the literature data analysis covering possible impact of contact lenses made of different materials (hydrogel, silicone hydrogel, soft and rigid gas permeable) on the development of dry eye symptoms, as well as the role of tear substitutes use when wearing contact lenses. Due to a great variety of different studies on this topic, the literature review on the tear substitutes instillation when wearing contact lenses in patients with dry eye syndrome is relevant and crucial for doctors in outpatient departments.

Conclusion. The research has shown that, it is possible to identify unmodifiable and modifiable risk factors for dry eye syndrome with reliable and probable factors. In addition, the therapeutic use of HYLO-COMOD and PARIN-POS is accompanied by minimum possible negative side effects and their use can increase the amount of tear film, as well as reduce the severity of eye discomfort.
