Relief
-
VISMED® has demonstrated better relief than saline in both intensity and frequency of symptoms in patients with moderate sensations of ocular dryness.1
-
A single drop of VISMED® increases break-up time (TBUT) of the prelens tear film for up to 4 hours in patients with sensations of ocular dryness due to contact lens wear.1 VISMED® demonstrated effectiveness in stabilizing the prelens tear film leading to improved comfort.

Protection
-
VISMED® accelerates the healing of corneal abrasions. A study showed that VISMED® decreased lissamine green staining in patients with moderate symptoms of ocular dryness, demonstrating improved corneal and conjunctival protection compared with saline.1
-
VISMED® has been specially formulated to provide a low contact angle on the corneal surface, thus ensuring an effective coating of the cornea.

Balance
-
VISMED® does not contain preservatives that have been demonstrated to cause toxic or allergic reactions in some patients.2,3
-
Tear osmolarity in healthy eyes is ~300 mOsm/L. In patients with sensations of ocular dryness, tear osmolarity is typically as high as 340 mOsm/L and has been associated with damage to the corneal epithelium.4,5 VISMED® is formulated to be hypotonic (150 mOsm/L) and, therefore, rapidly counteracts tear hypertonicity experienced with sensations of ocular dryness.

-
VISMED® contains similar concentrations of essential ions to those found in natural tears – calcium and magnesium are important in cell adhesion, cell junctions and cellular transport, and potassium contributes to the maintenance of corneal thickness.2,6
-
VISMED® patented formulations contain sufficient sodium citrate to maintain the phosphate and calcium ions in solution and therefore prevent corneal calcification due to precipitation of calcium phosphate.7
-
VISMED® is adjusted to a physiological pH of 7.3.
