Hycosan Extra Eye Drops 7.5ml are preservative-free lubricating eye drops specially formulated to provide soothing, long-lasting relief from persistent and severe dry-eye symptoms.

Containing 0.2% sodium hyaluronate (hyaluronic acid), Hycosan Extra helps retain moisture on the surface of the eye, support the natural tear film and reduce discomfort associated with dryness.

The higher concentration of sodium hyaluronate provides a more viscous lubricating solution than standard 0.1% hyaluronic acid eye drops, making Hycosan Extra particularly useful when additional moisture retention is needed.

The preservative-free multidose bottle contains approximately 225 drops and can be used for up to six months after first opening, according to the product packaging.

What Is Hycosan Extra Used For?

Hycosan Extra helps relieve symptoms associated with:

  • Persistent dry eyes: Provides lubrication when dryness is frequent or ongoing.
  • Severe dry-eye symptoms: Helps improve comfort when additional moisture retention is required.
  • Gritty eyes: Reduces the sensation of sand or grit caused by dryness.
  • Burning or irritated eyes: Soothes discomfort associated with inadequate tear lubrication.
  • Tired eyes: Helps relieve dryness-related discomfort after prolonged screen use.
  • Environmental dryness: Provides moisture when eyes are affected by heating, air conditioning, wind or dry air.
  • Contact lens-related dryness: May help improve lubrication and comfort for suitable contact lens wearers.

Key Benefits

Long-Lasting Dry-Eye Relief

Hycosan Extra contains 0.2% sodium hyaluronate, which binds water and helps maintain a lubricating moisture layer over the eye's surface.

Designed for Persistent and Severe Dry Eyes

Its higher-viscosity formulation is intended for people experiencing more pronounced or persistent dry-eye symptoms.

Preservative-Free Formula

Hycosan Extra contains no preservatives, making it suitable for people who require frequent lubrication or prefer to avoid preservative-containing eye drops.

Helps Protect the Tear Film

Sodium hyaluronate supports lubrication and helps reduce friction between the eyelid and the eye's surface during blinking.

Suitable for Contact Lens Wearers

Hycosan Extra can generally be used by contact lens wearers. Follow the product instructions and any advice from your optometrist.

Six-Month After-Opening Use

The specialised multidose dispensing system helps maintain the solution without preservatives and allows use for up to six months after opening.

Approximately 225 Drops

The 7.5ml bottle contains approximately 225 drops, depending on dispensing technique.

How Does Hycosan Extra Work?

Hycosan Extra contains sodium hyaluronate, a form of hyaluronic acid that naturally attracts and retains water.

When applied to the eye, sodium hyaluronate forms a lubricating film across the ocular surface.

This helps:

  • Retain moisture.
  • Reduce friction during blinking.
  • Improve tear-film stability.
  • Relieve dryness-related irritation.
  • Support comfort between applications.

The 0.2% concentration provides a thicker lubricating solution than lower-strength sodium hyaluronate eye drops.

Main Lubricating Ingredient

  • Sodium Hyaluronate – 0.2% (2mg/ml)
