Lipidure® is useful for contact lens solution ingredient preventing deformation, staining and bacterial adhesion on contact lenses.
LIPIDURE®, bio-compatible material, is useful for raw material of soft contact lenses The U.S. Food and Drug Administration (FDA) approved the lenses made from LIPIDURE® for those who feel discomfort from dryness using conventional contact lenses. LIPIDURE® is also used for contact lens solution (packing solution) and provides excellent dry out resistance, anti staining property, and prevention of bacterial adhesion.
Dry out resistance of soft contact lenses packed in LIPIDURE® solution
LIPIDURE® packing solution suppresses the deformation of soft contact lenses due to dehydration.
The top figure above shows the deformation of a soft contact lens placed on a circular ring. There was no significant difference in the lenses after 0 and 5 minutes, but the lens without LIPIDURE® solution was largely deformed after 15 minutes. The lens with LIPIDURE® solution started to deform after 15 minutes and was deformed after 20 minutes.
Anti staining property (lipid staining) of soft contact lenses packed in LIPIDURE® solution
LIPIDURE® packing solution suppresses lipid stains on soft contact lenses.
Anti staining property of LIPIDURE
LIPIDURE® packing solution suppresses bacterial adhesion to soft contact lenses.
