Sodium hyaluronate, also known as sodium hyaluronate, is a physiologically active substance widely present in the human body. , its molecular weight is 1 million.
It forms a thick viscoelastic solution in water with physiological pH and ionic strength. Its molecular shape is variable, so it can also be passed through with a thinner injection needle.
The non-inflammatory substance in sodium hyaluronate is extracted and called Healon. When 10mg of this product is dissolved in 1ml of normal saline, its viscosity can be 200,000 times higher than that of aqueous humor or normal saline. Healon contains less than 0.5% protein and is a sterile, high-purity solution.
Sodium hyaluronate has the effect of promoting wound healing.
Sodium hyaluronate can form a macromolecular network barrier on the surface of the eye tissue, prevent inflammatory substances from entering the wound and the lesion area, and can significantly improve the viscosity and adhesion of the drug solution, so that the drug can be stored on the corneal surface for a long time and concentratedly. To achieve long-term, strong effect.
Sodium hyaluronate stabilizes the tear film, prolongs the tear film breakup time, and relieves symptoms of dry eyes. For corneal burns caused by keratitis, corneal ulcers, corneal injury or other chemical and physical factors.
For intraocular lens, cataract, glaucoma, corneal transplantation and retinal detachment surgery.
Also widely used in high-end cosmetics industry.
