Precision in Surgery
Our ophthalmic viscosurgical devices are designed to support every phase of cataract and intraocular surgery. With carefully calibrated rheology and consistent molecular behavior, each formulation offers reliable chamber stability, tissue protection, and smooth handling. Manufactured using high-purity, non-animal sodium hyaluronate, our OVDs deliver trusted performance for surgeons who demand control and clarity.
Stopless and Safe
Surgery Possible
Our Ophthalmic Viscosurgical Devices (OVDs) are engineered for precision and safety throughout cataract surgery. Developed from high-purity, non-animal sodium hyaluronate via bio-fermentation, our portfolio includes both cohesive and dispersive solutions tailored for chamber stability, tissue protection, and instrument control. Each OVD is fully compatible with Alsanza IOLs, supporting smooth implantation and reliable outcomes in every procedure.
Science in Our OVDs
ALSAVISC is formulated with long, monotype HA chains for predictable viscoelastic performance. The homogeneous molecular structure ensures reversible viscosity, elastic shock absorption, and high shear-thinning for precise instrument movement. Molecular weights range from 750,000 to 3 million Daltons, with each formulation optimized for specific surgical needs—from coating and protection to space maintenance and aspiration.
