The available eye medications for dry eyes include artificial tears, lubricating creams, topical anti-inflammatory or immunosuppressive agents. Depending on the classification of dry eyes and the severity of the condition, different eye medications can be selected or used in conjunction. 1.Artificial tears: Artificial tears are the first line of treatment for dry eye. Lubricating the eye surface is the main function of artificial tears, and it can supplement the missing tears, dilute the soluble inflammatory mediators on the eye surface, reduce the osmotic pressure of tears and reduce the eye surface reaction caused by high osmotic pressure. The choice of artificial tears: mild dry eyes can choose artificial tears with low viscosity; for moderate to severe dry eyes, with evaporation too strong to choose artificial tears with high viscosity; for patients with heavy inflammation on the eye surface and abnormal tear dynamics prefer artificial tears without preservatives or preservatives with less toxicity. 2.Lubricating creams: ophthalmic gels and creams are kept on the eye surface for a longer time, but some of them can blur vision and are mainly used in patients with severe dry eyes or applied at night. 3.Topical anti-inflammatory and immunosuppressive agents: dry eye can cause a non-infectious inflammatory response in the epithelium of the eye surface. The heavier the degree of infection the heavier the inflammatory response. Anti-inflammatory and immunosuppressive treatment is applied to dry eye patients with inflammatory response on the ocular surface, and commonly used drugs are glucocorticoids, non-steroidal anti-inflammatory drugs and immunosuppressive drugs. In summary, artificial tears can be used for mild dry eyes, topical anti-inflammatory and immunosuppressive agents can be added if combined with inflammatory reactions, and ophthalmic gels can be added for severe dry eyes.
