<p>Disclosed are sterile hydrogel compositions comprising polyvinyl alcohol ('PVA'), polyvinyl pyrrolidone ('PVP'), and a polysaccharide, wherein the combined amount of PVA and PVP present in the hydrogel compositions is from about 2% to about 12% weight by volume, based on the total volume of the composition, and wherein the hydrogel compositions has a gel fraction greater than or equal to 97%. Sterile hydrogel products including such sterile hydrogel compositions, and methods of making such sterile hydrogel compositions and sterile hydrogel products.</p> |
