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.

Many gels display thixotropy – they become fluid when agitated, but resolidify when resting. In general, gels are apparently solid, jelly-like materials. It is a type of non-Newtonian fluid. By replacing the liquid with gas it is possible to prepare aerogels, materials with exceptional properties including very low density, high specific surface areas, and excellent thermal insulation properties.
