Introducing Hyabak®

Abak system logo Preservative free badge.
  • Hyabak contains sodium hyaluronate 0.15% in a preservative-free eye drop formulation
  • Sodium hyaluronate effectively hydrates and lubricates the surface of the eye1
  • Hyabak is a hypotonic solution, formulated to match the natural viscosity of tears
  • Hypotonic solutions have been shown to offer greater improvements than isotonic solutions2

Hyabak is a hypotonic solution which addresses the hyperosmolarity of the tear film in chronic dry eye and effectively reduces symptoms.1,2 Hyabak is clinically proven to relieve symptoms of dryness and grittiness, and provides long-lasting relief from eye discomfort and dryness. It is suitable for all dry eye patients including those with moderate to severe dry eye disease.1,2

Hyabak is delivered in uniquely designed, preservative-free bottle for easy application. Products containing preservatives can cause ocular surface toxicity, leading to inflammation and cell death. Using preservative-free eye drops supports the health of the ocular surface.
