Systane UD Lubricant Eye Drops

Systane UD offers a dual-lubricant system that combines hyaluronic acid with HP-Guar to provide extended moisture retention. It is well suited for patients requiring more sustained relief than standard eye drops, particularly those with sensitive or compromised ocular surfaces.

• Moderate or persistent dry eye  
• Sensitive eyes requiring preservative-free drops  
• Patients needing longer-lasting lubrication  
• Contact lens wearers  
• Post-surgical eye care (e.g. LASIK, cataract)

• Dual-action hydration system (HA + HP-Guar)  
• Provides longer-lasting lubrication and protection  
• Preservative-free unit dose format  
• Supports corneal surface healing  
• Suitable for frequent use and sensitive eyes  

Systane UD is a preservative-free lubricating eye drop formulated to provide sustained relief from moderate dry eye symptoms, including irritation, burning, and ocular fatigue. Its advanced dual-action system combines sodium hyaluronate with HP-Guar, creating a protective, gel-like layer over the ocular surface that enhances moisture retention. 

Dry eye disease often involves instability of the tear film and damage to the ocular surface. Systane UD helps restore hydration while supporting surface protection, making it particularly useful for patients requiring longer-lasting relief or those with increased sensitivity. 

The unit dose format ensures preservative-free delivery, which is important for frequent use and for patients with compromised ocular surfaces, such as those recovering from surgery. Within the range of eye drops available in Australia, Systane UD sits between standard lubricants and more intensive gel formulations, offering a balance of comfort and duration. 

The combination of hyaluronic acid and HP-Guar forms a viscoelastic protective layer on the eye. Thisstabilisesthe tear film, reduces evaporation, and supports healing of the ocular surface.

Choose this product if you require preservative-free, longer-lasting lubrication for moderate dry eye, particularly in a convenient unit dose format for sensitive eyes. 

You may prefer Hylo-Fresh if you have mild dry eye and are looking for a lighter, multi-dose drop for frequent daily use. 

You may prefer Hylo-Forte if you require more intensive, longer-lasting lubrication for moderate to severe dry eye with a higher concentration of sodium hyaluronate. 

Compared with TheraTears Drops (Unit Dose), this option is better suited for patients requiring longer-lasting hydration and enhanced tear film retention, rather than a lighter drop primarily focused on electrolyte balance and tear film support.
