Zusammenfassung:A triple natural polymer viscoelastic composition is disclosed. By combining glucosamine sulfate (''GS''), sodium hyaluronate (''HA'') and chondroitin sulfate (''CS''), the triple natural polymer viscoelastic compositions of this invention can provide a viscoelastic agent at a surgical site that not only serves as a protective agent to ocular tissues, but that can also act as an agent to alleviate pain and inflammation associated with ocular surgery. Embodiments of this invention can comprise GS combined with existing HA/CS viscoelastic agents. Embodiments of this invention can also comprise GS and CS in combination with an irrigation solution. Further, to enhance retention time at the site of an intra-articulate application of an embodiment of this invention, the following biodegradable polymers may also be included in an embodiment of the compositions of the present invention: cellulose derivatives (e.g., hydroxypropylmethylcellulose, ethylcellulose, caboxymethylcellulose, etc.), carbopol, citosan, and collagen.
