Hywini Eye Drop contains Sodium Hyaluronate 0.1% w/v, a viscoelastic agent widely used in ophthalmology for the management of dry eye syndrome and other ocular surface disorders. Sodium Hyaluronate is a naturally occurring glycosaminoglycan with excellent water-retaining properties, providing effective lubrication and moisture retention on the ocular surface. Hywini Eye Drop is indicated for symptomatic relief of dry, irritated, or fatigued eyes caused by environmental factors, prolonged screen exposure, contact lens wear, or postoperative conditions. The formulation enhances tear film stability, promotes epithelial healing, and reduces ocular discomfort by mimicking the natural tear film. It is suitable for frequent use due to its biocompatibility and low risk of adverse effects. Hywini Eye Drop is preservative-free, minimizing the potential for preservative-related toxicity and irritation, making it appropriate for patients with sensitive eyes. Administration involves instilling one or two drops into the affected eye(s) as needed, with dosage adjusted according to symptom severity. Patients are advised to avoid contamination of the dropper tip and to consult an ophthalmologist if symptoms persist or worsen. Hywini Eye Drop is a safe and effective option for maintaining ocular surface integrity and improving patient comfort in dry eye management.
