Gylan® Dex is a sterile 0.18% aqueous sodium hyaluronate solution with 2% dexpanthenol, free of preservatives.
The active substance, highly purified sodium hyaluronate, is produced by bacterial fermentation. Sodium hyaluronate is a physiological polysaccharide compound found both in eye tissues and in other human tissues and fluids.
A specific physicochemical property of sodium hyaluronate molecules is their strong ability to bind water molecules. Its aqueous solution (GYLAN) has the necessary viscosity and strong adhesive properties, effectively moisturizing the eye surface.
The solution also contains provitamin B5 (dexpanthenol), which has high water-binding capacity, further moisturizing the eyes and enhancing the hydration effect of sodium hyaluronate. Dexpanthenol also has anti-inflammatory and wound-healing properties, supporting faster regeneration of the eyes after trauma and surgery.
When applied, Gylan® Dex forms a thin, even film on the corneal epithelium, protecting the eyes from dryness, irritation, and inflammation of the anterior eye surface. The protective film acts instantly and provides long-term protection from dryness, burning, foreign body sensation, and irritation caused by computer work, air conditioning, or environmental factors. The precorneal tear film formed after instillation remains stable for a long time, is not washed away by blinking, and does not impair visual acuity.
Adequate eye surface hydration with Gylan® Dex helps normalize physiological processes and accelerates healing after trauma and surgery.
Gylan® Dex effectively and rapidly relieves symptoms of dry eye syndrome of varying severity: eliminates foreign body sensation, burning, and stinging, reduces fatigue from intense visual strain, relieves discomfort, and helps maintain healthy eyes.
In cases of regular contact lens wear, Gylan® Dex is recommended as it provides long-lasting eye hydration, similar to natural tears. Viscosity: 3.5–15.0 mPa·s. It makes both soft and rigid contact lenses more comfortable to wear without depositing on their surfaces.
The solution contains no preservatives, thus avoiding toxic effects on eye tissues and being well tolerated even with prolonged use.
Thanks to the special dropper bottle, the solution remains sterile throughout its shelf life after opening. Sterility is ensured by the design of the dropper: a spring mechanism prevents backflow into the bottle, and a sterilizing multilayer membrane filter in the air channel maintains sterility.
