Medical applications of PVA

PVA hydrogel has the characteristics of water content, elastic modulus, low friction coefficient, high mechanical strength, rich pore leakage network structure, and good biocompatibility similar to the natural tissues of the human body. Wide range of applications. It can be used to manufacture artificial cartilage, artificial cornea, artificial vitreous, etc. Polyvinyl alcohol hydrogel is widely used in ophthalmology and can be used to make soft contact glasses. Because of its water solubility, it can be made into sustained-release drug capsules. A new type of medical non-fiber sponge made by introducing sodium polyacrylate side chains into PVA macromolecules is called ionized polyvinyl alcohol sponge (i-PVA spong). It has good biocompatibility and stable chemical properties, and has excellent properties. The hydrophilic, liquid and blood-sucking properties. i-PVA sponge can be effectively used in medical operations such as microsurgery and eye surgery that strictly require no fiber shedding, especially in cataract and intraocular lens replacement surgery.
