Hydrogels are generally characterized by their hydrophilicity. It is the most important aspect being the absorbed amount of water, often defined as the equilibrium water content (EWC). In biomedical fields, high water content is an attractive attribution related to higher oxygen permeability, low cell adhesion and protein absorption. Resently, many researchers have noted the myriad possible applications of sugar-containing polymeric meterials, which can synthesize from sugar esters. Sugars constitute an attractive group of multifunctional compounds, since they are biologically relevant and they harbor multiple hydroxyl groups. Sugar esters, which contain sugar molecules, have been receiving increased amount of interest, and are already being utilized in a variety of applications as contact lens materials. In this study, the properties of poly-sorbitan methacrylate hydrogel as soft-lens material were investigated. The tested properties are moisture content, oxygen permeability, and light transmittance.
