Dry eye is a common eye disease. Many patients have mild symptoms of dry eyes and do not require medication; however, a significant number of patients have persistent dry eye symptoms and abnormal tear tests that require treatment. Because the causes of dry eye vary, individualized treatment is needed for different patients. The main eye medications used to treat dry eyes include artificial tears and anti-immune inflammatory response drugs. The main types of artificial tears include, glucose anhydride eye drops (e.g. Beyran), polyethylene glycol eye drops (e.g. Siren), sodium carboxymethylcellulose eye drops (Xiaolaiwei, Bright Vision), vitamin A palmitate eye drops (Lepe gel), carbomer sorbate eye drops (Vadisil gel), sodium hyaluronate eye drops (Ally), polyvinyl alcohol eye drops (Liquefin, Rizum), etc. After more than ten years of research, it was found that immune inflammatory factors play a very important role in the pathogenesis of dry eye, so anti-immune inflammatory response ophthalmic drugs have been used to achieve clinical results in the treatment of dry eye disease, and such drugs include corticosteroid ophthalmic solutions, cyclosporine eye drops, and non-steroidal anti-inflammatory ophthalmic solutions (such as pralofene). The ocular surface toxicity caused by the preservatives contained in artificial tears is becoming a concern in the treatment of dry eye disease.
