Rohto® Dry Aid™ advanced clinically proven eye drop designed to work on both Aqueous Deficient and Evaporative Dry Eye.

As an intensive Dry Eye relief drop which breaks the cycle of Dry Eye effectively. Its unique lipid enhancing formulation Tearshield Technology® target all layers of the tear film, aiming to end the vicious cycle of dry eye.

The unique lipid-enhancing formulation is particularly effective for evaporative dry eye as it enhances the thickness of the lipid layer and the spread, stabilising the tear film and restoring its natural function – breaking the cycle of dry eye effectively.

Rohto® Dry Aid™ works on all layers of the tear film.

Ingredients for restoring the lipid layer

Seasame Oil*

Sesame oil has a very similar physical property to meibum. It thickens the lipid layer and helps create a lipid shield over Dry Eye spots repairing the lipid layer – preventing evaporation from the aqueous area. Rohto’s scientific research demonstrated that the sesame oil in Rohto® Dry Aid™ drops mixes and spreads homogeneously with lipid layer compounds, proving it is effective for the treatment of EDE.* It also shows sesame oil provides a significantly greater and more uniform coating than mineral oils used in other eye drops.

Polyoxyl Stearate

Polyoxyl Stearate helps the Lipid film become more uniform.

Menthol

Rohto’s scientific research demonstrated that Menthol in the Rohto® Dry Aid™ formulation helps mimic the lipid layer structure, increase the lipid layer’s stability and it enhances the upward spread of the tear film – which enhances tear film stability.

Polyoxyethylene  Castor Oil

Polyoxy-ethylene Castor Oil

Polyoxyethylene Castor Oil helps make meibum a more homogeneous lipid film. Studies have shown that it helps stabilise and thicken the lipid layer and, it helps reduce corneal drying. Trials have confirmed that overall, the Rohto® Dry Aid™ formulation reduces tear evaporation and extends Dry Eye symptom relief by increasing Tear Film Break Up Time (TFBUT).

Polyhexamethylene biguanide (PHMB)

Ingredients for restoring the muco-aqueous layer

Propylene glycol

Propylene glycol is well-tolerated liquid which attracts water. It is clinically proven to help hydrate the tear film, particularly the mucin area.

Electrolytes

Electrolytes (magnesium and calcium): Rohto® Dry Aid™ contributes to the maintenance of tear film homeostasis by replenishing the magnesium and calcium found in tears.

Poloxamer

Poloxamer is thermo-responsive, and when dispersed in water, turns into hydrogel. It works in two distinct modes in Rohto® Dry Aid™: its lipid-friendly lipophilic blocks protect the ocular surface by binding to membrane lipids on the corneal epithelium cells or lipid area, while its hydrophilic blocks are water-retentive, contributing to tear film stability, all helping the surface of the eye.

Povidone

Povidone is a polymer which has the ability to hold water and coats the surface of the cells to prevent friction. It holds other ingredients in the tear film and makes them long lasting. By bolstering the tear film, it also reduces water loss and protects the cornea.

Polyoxy-ethylene Castor Oil

Polyoxyethylene  Castor Oil

PHMB is a mild, gentle, eye-friendly preservative used in some contact lens solutions and eye drops. Its antiviral and antibacterial properties mean Rohto® Dry Aid™ drops can be used safely for up to 3 months after opening. PHMB has been shown to have an extremely low level of irritation in comparison to other preservatives including BAK.
