Lipidure which stabilizes tear film is useful for dry eye drops.
Ingredient for dry eye
LIPIDURE® has high hydrophilicity as well as tear film stabilizing effect and can also alleviate irritation from preservatives contained in eye drops.
The figure above shows a visual representation of BUT using TSAS (Tear stability Analysis System). If tear dries right after blinking, the color turns orange or yellow; if it takes longer to be moistened, the color turns green.
Safety of LIPIDURE® for eye drops
LIPIDURE® can protect corneal cells and is very safe.
The image is the scanning electron microscope (SEM) result of a three dimensional corneal cell model. The corneal cell remained intact after applying saline and LIPIDURE® eye drop.
The surface of the corneal cell was irritated after treatment in product A, while there was damage to the surface of the corneal cell and the cell was separated in product B.
