HyaloRx PF HS Eye Drop contains Sodium Hyaluronate 0.18% w/v, a viscoelastic agent used to provide effective lubrication and hydration to the ocular surface. This preservative-free formulation is specifically designed for the management of dry eye syndrome and other conditions characterized by ocular surface dryness and irritation. Sodium Hyaluronate, a naturally occurring glycosaminoglycan, exhibits excellent water-retention properties, promoting prolonged moisture retention and enhancing tear film stability. HyaloRx PF HS Eye Drop helps to alleviate symptoms such as burning, stinging, foreign body sensation, and redness associated with dry eyes. Its high molecular weight formulation ensures optimal viscosity, providing a protective coating that facilitates corneal epithelial healing and reduces friction during blinking. The preservative-free nature of this preparation minimizes the risk of ocular surface toxicity and irritation, making it suitable for frequent and long-term use, including in patients with sensitive eyes or those wearing contact lenses. HyaloRx PF HS Eye Drop is indicated for patients experiencing mild to moderate dry eye symptoms, postoperative ocular surface dryness, or exposure keratopathy. It is recommended to instill one or two drops into the affected eye(s) as needed or as directed by a healthcare professional.
