Instatear Eye Drop contains Sodium Hyaluronate 0.1% w/v, a viscoelastic agent used to provide effective lubrication and hydration of the ocular surface. This ophthalmic solution is indicated for the relief of dry eye symptoms, including irritation, burning, and foreign body sensation caused by environmental factors, contact lens wear, or reduced tear production. Sodium Hyaluronate acts by retaining moisture on the corneal and conjunctival epithelium, promoting epithelial healing and enhancing tear film stability. The formulation is isotonic and preservative-free, minimizing the risk of ocular irritation and allergic reactions, making it suitable for frequent and long-term use. Instatear Eye Drop is typically administered as one to two drops in the affected eye(s) as needed, with dosage adjusted based on symptom severity. It is contraindicated in patients with known hypersensitivity to any component of the formulation. Caution is advised in cases of ocular infections or injuries, where medical evaluation is recommended before use. Instatear Eye Drop offers a safe and effective option for managing dry eye syndrome, improving patient comfort and visual clarity by restoring optimal ocular surface moisture.
