It is a polymer with an average molecular weight of 52,350 and is made up of three sugars; glucose, galactose and xylose in the molar ratio of 3:1:2.
TSP has a branched chain made up of a cellulose polysaccharide protruding from the main chain that transports xylose and galactose,

The Soft Contact Lenses
• Sponge effect: due to eyelid pressure deforms the lens favours the release of the copolymer.
• Blinking: thanks to eyelid friction, reduces the viscosity of the copolymer, helping it to be released.
• The increased temperature of the cl when it comes into contact with the ocular surface exploits the thermo-reversible properties of the copolymer guaranteeing
Research
The characteristics of the two natural polymers, TSP and HA, provide the opportunity to create a synergy that enhances their already notable properties: hydration, wetting, protection of the ocular surface and favouring the regrowth of the epithelial microvilli.
