Hi-Tech Medical Sodium Hyaluronate Gel is transparent viscous, cohesive, viscoelastic solution made by dissolving highly pure, high molecular weight Sodium Hyaluronate in physiological saline. It is sterile, nonpyrogenic, non-irritative and noninflammatory. Sodium Hyaluronate maintains an optimal intraocular space in anterior chamber and protects corneal endothelium from mechanical damage during ophthalmic surgeries. Sodium Hyaluronate, which is a polymer polysaccharides of biological materials formed by N-acetyl glucosamine and glucuronic acid through iterative connected, has a high degree of viscoelasticity, plasticity, permeability and good biocompatibility. This product is manufactured with raw material of bio-fermentated Hyaluronic Acd based on the process of fine biochemical technology, separation, purification and refining. This product, which is a colorless, odorless, sterile, pyrogen free transparent viscous liquid, adopts the aseptic processing technology to filter sterilization.
