Sodium hyaluronate ua raws li cov ntaub so ntswg lubricant thiab suav tias yog lub luag haujlwm tseem ceeb hauv kev tswj kev sib cuam tshuam ntawm cov ntaub so ntswg uas nyob ib sab. Nws tsim ib qho kev daws teeb meem viscoelastic hauv dej. Lub siab viscosity ntawm cov tshuaj muab kev tiv thaiv txhua yam rau cov ntaub so ntswg (iris, retina) thiab cell txheej (cornea, endothelium, thiab epithelium). Lub elasticity ntawm cov tshuaj pab nqus cov neeg kho tshuab kev nyuaj siab thiab muab kev tiv thaiv buffering rau cov ntaub so ntswg. Hauv kev txhawb kev kho qhov txhab, nws ntseeg tau tias ua raws li kev tiv thaiv kev thauj mus los, nqa peptide kev loj hlob yam tseem ceeb thiab lwm yam txheej txheem proteins mus rau qhov chaw ua haujlwm. Tom qab ntawd enzymatic degradation thiab tso tawm cov active proteins los txhawb cov ntaub so ntswg kho.
