AI Technical Summary
Existing polyvinyl alcohol eye drops have a single function and cannot effectively alleviate the problems of ocular surface cell metabolic disorders and decreased antioxidant capacity caused by eye fatigue, dry eye syndrome and other conditions in modern life. Furthermore, there are no reports of compound eye drops combining polyvinyl alcohol and taurine.
A compound eye drop containing 0.8%-1.2% taurine and 1.2%-1.6% polyvinyl alcohol was prepared. By combining it with conventional pharmaceutical excipients such as isotonic agents, pH adjusters and thickeners, a synergistic effect was achieved through a specific ratio and preparation method to enhance moisturizing properties and corneal epithelial damage repair capabilities.
It achieves longer-lasting hydration and faster corneal epithelial damage repair, significantly relieving symptoms of visual fatigue syndrome such as dryness, stinging, and photophobia. It is superior to single-component eye drops and enhances the recovery effect of visual function.
