Key Benefits
1. Ophthalmic-Grade High Safety Standards
Sodium hyaluronate is produced using pharmaceutical-grade processes with strict control over endotoxins, heavy metals, and microbial limits, meeting the requirements for direct ophthalmic use.
2. Excellent Moisturizing and Lubricating Properties
With strong hydrophilicity, sodium hyaluronate forms a moisturizing film on the ocular surface and contact lenses, reducing dryness and friction.
3. Good Biocompatibility
Highly similar to natural tear components, sodium hyaluronate is gentle and non-irritating to ocular tissues, making it suitable for sensitive eyes.
4. Superior Film-Forming and Long-Lasting Lubrication
Sodium hyaluronate forms a stable lubricating layer on the lens surface, alleviating discomfort and dryness associated with contact lens wear.
5. Good Formulation Compatibility
Sodium hyaluronate is compatible with a wide range of common ophthalmic excipients (e.g., electrolytes, buffer systems, preservative systems), making it suitable for various dosage form developments.
Mechanism of Action
1. Forms a Stable Hydrated Protective Layer
Sodium hyaluronate molecules bind strongly with water molecules, rapidly forming a uniform hydration film on the ocular surface and contact lenses. This hydrated layer effectively maintains a local moist environment, reducing dryness and water loss.
2. Enhances Tear Film Stability
By increasing the viscoelasticity and water-holding capacity of tears, sodium hyaluronate delays tear film breakup time and promotes more even tear distribution across the corneal surface, thereby enhancing overall tear film stability.
3. Reduces Friction and Mechanical Irritation
During blinking, sodium hyaluronate creates a lubricating interface between the contact lens and the cornea, reducing frictional resistance and alleviating foreign body sensation, dryness, and mild irritation caused by mechanical friction.
4. Delays Tear Evaporation and Prolongs Moisturizing Duration
The high-molecular-weight structure of sodium hyaluronate provides excellent water-locking capability, slowing down tear evaporation, extending the duration of ocular surface hydration, and enhancing sustained comfort.
5. Improves Contact Lens Wearing Experience
By optimizing lens surface lubrication and biocompatibility, sodium hyaluronate helps reduce dryness and discomfort during lens wear, improving tolerance and comfort for long-term wear.
