透明质酸钠广泛存在于动物和人体的生理活性物质，在人皮肤、关节滑膜液、脐

Sodium hyaluronate is widely present in animal and human physiologically active substance, are distributed in human skin, synovial fluid, umbilical cord, in vitreous and aqueous humor. A molecular weight of 500,000 to 730,000 daltons, which solution has a high viscosity and elasticity of the profiling, the auxiliary agent is an ophthalmic surgery, the anterior chamber after the liquid is injected to maintain a certain depth of the anterior chamber, to facilitate surgical procedure and protect corneal endothelial cells and eye tissue, reduce surgical complications, and promote wound healing.

Sodium hyaluronic acid is widely found in animals and human body physiologically active substances, in human skin, joint sliding membrane fluid, umbilical cord, room water and eye glass are distributed. The molecular weight is 500000 to 73000, its solution has high mucosal elasticity and proform, for the ophthalmic surgery of the auxiliary agent, the liquid injection of the front room to maintain a certain depth of the front room, easy to operate, and protect the cornea endothelial cells and intra-eye tissue, reduce surgical complications, promote the role of wound healing.

Sodium hyaluronate widely exists in animals and human physiological active substances, and it is distributed in human skin, synovial fluid of joints, umbilical cord, aqueous humor and vitreous body. With a molecular weight of 500000-730000 Dalton, the solution has high viscoelasticity and profiling. It is an auxiliary agent for ophthalmic surgery. After the solution is injected into the anterior chamber, it can maintain a certain depth of the anterior chamber, facilitate the operation, protect the corneal endothelial cells and intraocular tissues, reduce the complications of the operation, and promote wound healing.
