VISMED GEL for Persistent Symptoms


Sodium hyaluronate 0.3%, a higher concentration for sustained effect in the relief of sensations of ocular dryness

 


Relief

  • VISMED® GEL provides increased relief from subjective symptoms of ocular dryness, in terms of peak effect and duration of action, compared with both saline (0.9% NaCl) and less viscous solutions of SH in patients with symptoms of moderate intensity.1

  • VISMED® GEL also demonstrated improvements in non-invasive break-up time (NIBUT) over saline and less concentrated solutions of SH due to its prolonged residence time, ensuring tear film integrity and stability over the eye surface.

Protection

  • A low contact angle provides greater coatability. The balance of molecular weight and concentration of SH in VISMED® GEL ensures that a low angle of contact is achieved on the corneal surface. Thus, VISMED® GEL spreads effectively over the surface of the cornea to provide a protective coating.

  • SH 0.3% has been shown to increase the thickness of the tear film more efficiently than buffer solution, offering increased protection from sensations of ocular dryness.3

Balance

  • VISMED® GEL is preservative-free, avoiding potentially toxic or allergic reactions that have been associated with some preservative agents.1

  • VISMED® GEL is hypo-osmolar (150 mOsm/L) relative to natural tears, counteracting the hypertonicity associated with ocular dryness that has been implicated in ocular surface damage.4,5  Click here for more information on the hypotonicity of VISMED® eye drops.

  • VISMED® GEL’s unique patented formula combines SH with the essential ions found in natural tears that are required to maintain healthy corneal function.1,6

  • The pH of VISMED® GEL is adjusted to 7.3 – similar to that of the natural tear film.
