  • Concentration: Bio-Hyalur DUO pack contains two pre-filled OVD (Ophthalmic Viscoelastic Device) syringes. Each syringe contains a specific concentration of sodium hyaluronate: 1.0% and 2.4% w/v.
  • Viscosity: Bio-Hyalur DUO exhibits different viscosities at zero shear rate for each concentration: 300,000 mPas for the 1.0% concentration and 1,000,000 mPas for the 2.4% concentration. These rheological properties are tailored to provide distinct profiles and reliability for various types of intraocular surgeries.
  • Packaging: Bio-Hyalur DUO syringes are supplied in pre-filled syringe format along with 27G sterile cannula, ensuring ease of use and precise application during surgical procedures.


The primary active ingredient in Bio-Hyalur DUO is sodium hyaluronate, a naturally occurring polysaccharide that is highly biocompatible and biodegradable. Sodium hyaluronate is known for its viscoelastic properties, making it an ideal choice for ophthalmic surgeries where maintaining space and protecting delicate structures are paramount.


Bio-Hyalur DUO is specifically formulated for use during surgeries in the anterior segment of the human eye. It is utilized in a variety of ophthalmic procedures where maintaining anterior chamber depth and visibility is essential, including but not limited to:


  • Maintains Anterior Chamber Depth and Visibility: Bio-Hyalur DUO effectively creates and Optimal Surgical Performance: Bio-Hyalur DUO’s dual concentration system offers surgeons the flexibility to customize the viscosity and rheological properties of the viscoelastic solution according to the specific requirements of each surgical procedure. This customization enhances surgical precision, efficiency, and overall performance.
  • Tissue Protection: By creating and maintaining a deep anterior chamber and minimizing tissue interaction during surgical manipulation, Bio-Hyalur DUO helps protect delicate intraocular tissues, including the corneal endothelium, from trauma and damage. This protective effect is critical for achieving optimal surgical outcomes and preserving long-term ocular health.
  • Enhanced Visibility: The viscoelastic properties of Bio-Hyalur DUO improve surgical visibility by stabilizing the anterior chamber and reducing intraocular turbulence. This enhanced visibility enables surgeons to perform delicate maneuvers with greater accuracy and confidence, ultimately contributing to improved patient outcomes and safety.
  • Convenient Packaging: Bio-Hyalur DUO is supplied in pre-filled syringes with sterile cannulae, offering convenient and hassle-free delivery during surgical procedures. The medical-grade blister packaging ensures sterility and minimizes the risk of contamination, further enhancing patient safety and procedural efficiency.
  • Versatile Applications: Bio-Hyalur DUO is suitable for a wide range of anterior segment surgeries, including cataract surgery, glaucoma procedures, and corneal transplantation. Its versatile applications make it a valuable tool for ophthalmic surgeons seeking optimal surgical outcomes across various clinical scenarios.
