Eye-Drop Application of Hyaluronic Acid (HA)
Hyaluronic Acid (HA) is an innovative new visco-enhancer for use in topical eye drops. HA naturally exist in human body tissues. It forms viscous moisture cushion that is renewed with each blink and helps eyes stay comfortable. HA is one of the most efficient molecules found in nature in absorbing moisture from the air. Hydrated HA can contain up to 1000 times more water than its weight, which makes it lock in moisture, lubricate and coat the surface of the eye providing a long lasting protection to the eye surface. Studies show that HA can relieve various dry eye symptoms by prolonging the stability of the pre-corneal tear film. HA can also promote wound healing thus reducing the healing time of the eye surface.
