Hyane Eye Drop contains Sodium Hyaluronate 0.18% w/v, a viscoelastic agent used to provide effective lubrication and hydration of the ocular surface. It is indicated for the relief of symptoms associated with dry eye syndrome, including irritation, burning, and foreign body sensation. Sodium Hyaluronate is a naturally occurring glycosaminoglycan with high water retention capacity, which helps to maintain tear film stability, promote corneal epithelial healing, and protect against desiccation. Hyane Eye Drop is particularly beneficial in cases of aqueous tear deficiency and evaporative dry eye, as well as following ocular surgery or exposure to environmental irritants. The formulation is preservative-free, minimizing the risk of ocular surface toxicity and ensuring suitability for frequent use. Administration involves instilling one or two drops into the affected eye(s) as needed, with dosage adjusted according to symptom severity. Hyane Eye Drop is well-tolerated, with minimal adverse effects reported, primarily limited to transient mild discomfort upon instillation. It is contraindicated in patients with known hypersensitivity to any component of the formulation. Overall, Hyane Eye Drop offers a safe and effective option for managing dry eye symptoms and maintaining ocular surface integrity.
