How SYSTANE^® Works

SYSTANE^® Lubricant Eye Drops contain a unique gelling and lubricating
polymer system formulated to adjust to each patient's individual
tear film pH. This ensures optimum properties for each user
and provides enhanced relief on a patient-to-patient basis.

The polymerizing protection of SYSTANE^® is achieved through
the interaction of the demulcents (polyethylene glycol 400 and
propylene glycol), HP-Guar and the patient's natural tears.
When HP-Guar combines with natural tears, a chemical
reaction occurs. HP-Guar binds to the hydrophobic (water
repellant) surface, forming a network with a gel-like
consistency. HP-Guar helps keep the demulcent
system on the surface of the eye longer.

SYSTANE^® creates an ocular shield, allowing epithelial repair in a healthy environment. The lasting protection of SYSTANE^® provides relief and comfort that lasts and lasts!
