Polyvinyl alcohol (PVA) eye drops are synthetic ophthalmic lubricants produced via hydrolysis of polyvinyl acetate. The chemical structure is defined by the formula (C₂H₄O)ₙ, with CAS No. 9002-89-5. These solutions function as artificial tears to restore ocular surface moisture.
Avoid use if hypersensitivity occurs; discontinue immediately upon signs of severe inflammation. Store in a cool, dry place below 25°C and protect from direct sunlight to maintain viscosity and sterility. Do not use if solution becomes discolored.
