Hyalan (Sodium Hyaluronate)

Hyalan is used to address several ocular surface conditions where additional lubrication and moisture are needed. It is commonly employed in the following situations:

• Relief of symptoms associated with dry eye disease.
• Adjunct therapy after ocular surgery to promote healing.
• Management of discomfort related to contact lens wear.
• Treatment of mild corneal epithelial defects.
• Supportive care for patients with allergic conjunctivitis.
• Use in conjunction with other eye drops to enhance overall comfort.

• Sodium hyaluronate is a high‑molecular‑weight polysaccharide that binds water molecules, increasing the viscosity of the tear film. When applied to the ocular surface, it forms a protective, hygroscopic layer that reduces evaporation, stabilizes the tear film, and creates a moist environment that facilitates corneal epithelial cell migration and wound repair, thereby supporting ocular surface health.

Adverse reactions to Hyalan are generally mild, but some users may experience more serious events. Awareness of potential side effects helps ensure prompt management.

Common

• Transient blurred vision after instillation.
• Mild eye irritation or burning sensation.
• Temporary foreign‑body feeling.
• Slight redness of the conjunctiva.
• Mild tearing or discharge.

Serious

• Allergic reaction with swelling or itching.
• Severe eye pain or photophobia.
• Sudden loss of vision.
• Development of corneal ulceration.
• Marked increase in intra‑ocular pressure.

Before using Hyalan, consider the following safety measures to minimize risk and ensure appropriate use.

• Verify that you have no known hypersensitivity to sodium hyaluronate or any excipients.
• Consult an eye‑care professional if you have active eye infection, inflammation, or recent ocular surgery.
• Discontinue use and seek medical advice if irritation, redness, or visual changes persist.
• Keep the container tightly closed when not in use to prevent contamination.
• Use only as directed; avoid sharing the product with others.
• Store at room temperature, protected from light and moisture.
• Keep out of reach of children.

Hyalan may interact with other ophthalmic agents, affecting efficacy or safety. Review the following interaction guidance.

Avoid

• Simultaneous use of multiple preservative‑containing eye drops that may increase ocular surface irritation.
• Instilling other drops immediately before Hyalan, which can dilute its lubricating effect.

Use with caution

• Co‑administration with topical corticosteroids or non‑steroidal anti‑inflammatory eye drops.
• Use while wearing contact lenses; remove lenses before instillation and wait before reinserting.
• Application in eyes undergoing recent surgical procedures.
• Concurrent use of systemic hyaluronate products, although systemic absorption is minimal.
