WebbThe xlHA gel used in this study (Restylane-L™) was injected into the lower canaliculus to block the outflow of tears. The xlHA gel swells and molds to the inner surface of the canaliculus. It effectively seals the lacrimal outflow system resulting in increased retention of tears on the ocular surface.

Gelation can occur either by physical linking or by chemical crosslinking. While the physical gels involve physical bonds, chemical gelation involves covalent bonds. The first quantitative theories of chemical gelation were formulated in the 1940s by Flory and Stockmayer. Critical … Visa mer In polymer chemistry, gelation (gel transition) is the formation of a gel from a system with polymers.
