I-sodium hyaluronate isebenza njenge-lubricant yezicubu futhi ibhekwa njengedlala indima ebalulekile ekulawuleni ukusebenzisana phakathi kwezicubu eziseduze. Yakha isisombululo se-viscoelastic emanzini. I-viscosity ephezulu yesisombululo inikeza ukuvikelwa komshini kwezicubu (iris, retina) kanye nezingqimba zamaseli (i-cornea, i-endothelium, ne-epithelium). Ukunwebeka kwesixazululo kusiza ukumunca ukucindezeleka komshini futhi kunikeze ukuvinjelwa okuvikelekile kwezicubu. Ekukhuthazeni ukuphulukiswa kwesilonda, kukholakala ukuthi kusebenza njengethuluzi lokuthutha elivikelayo, ukuletha izici zokukhula kwe-peptide namanye amaprotheni esakhiwo endaweni yokusebenza. Khona-ke ukuwohloka kwe-enzymatic nokukhululwa kwamaprotheni asebenzayo ukukhuthaza ukulungiswa kwezicubu.
