The VISMED Product Line

The VISMED® range, including the specific products you mentioned, is a line of sterile, preservative-free lubricant eye drops designed to relieve symptoms of dry eye and/or ocular surface damage.

Active Ingredient:
The primary active ingredient is sodium hyaluronate (hyaluronic acid), a natural polymer known for its excellent water-retaining and visco-elastic properties.

Formulation:
The products are formulated as a hypotonic solution that contains essential ions like potassium, magnesium, and calcium, closely mimicking natural human tears. This helps to counteract tear hyperosmolarity and stabilize the tear film.

Specific Products Mentioned:

VISMED® Lubricante Ocular (EAN 4028694000133):
This is the standard solution containing 0.18% sodium hyaluronate in single-dose vials for regular symptoms of dryness, burning, or eye fatigue.

VISMED® Gel Ocular (EAN 4028694000188):
This product has a higher concentration of 0.30% sodium hyaluronate for more sustained lubrication and relief from persistent or severe dry eye symptoms.

Usage:
All VISMED products are compatible with all types of contact lenses (rigid or soft) during wear. The single-dose containers should be discarded within 12 hours of opening as they lack preservatives.
