"People with dry eye should try to minimise their time in environments that can cause or worsen their symptoms, such as air-conditioned offices without natural ventilation and motor vehicles. However, understandably, this is not always possible. Hot compresses and eyelid massages are good techniques to improve symptoms of dry eye. These techniques can be combined with supplemental artificial tears and, in some instances, Omega-3 supplements. Using a solution that contains a preservative, which is a chemical used to prolong the shelf-life of the solution, can sometimes cause inflammation and irritation and worsen the dry eye, so it is better to choose one that is preservative-free."

Hydration is important

In addition to lifestyle changes, dry eye can usually be managed with hydrating eye drops or artificial tears. In general, mild cases are treated using eye drops that help to retain moisture, eye drops containing moisturising ingredients, and other formulations to replenish the quantity and quality of tears.

It is very important to improve the quality and quantity of tears in the treatment, and eye drops can often help. However, if dry eye cannot be managed with eye drops, treatments may be given to suppress the outflow of tears.

Gels and ointments are also available and are thicker than eye drops. They usually last longer in the eye and need to be put in less frequently, but can blur the vision.

For those who wear contact lenses, finding an effective dry eye treatment means they can continue to use contact lenses rather than revert back to glasses. Please note that some treatments for dry eye may not be compatible for use with contact lenses.

Find the right long-term solution for you

Some eye drops contain a preservative to kill bacteria and fungi that may contaminate the fluid in the bottle. For years, dry eye drops have contained preservatives specifically designed to keep the medication sterile for the time it’s being used. However, these preservatives contain harsh chemicals that can cause irritation to the eye’s surface.

In recent years, manufacturers have begun introducing preservative-free eye drops. If you use eye drops often that contain preservatives, it might be worth seeing if a preservative-free option is available.

Early treatment prevents long-term damage

Although usually not serious, treating and managing dry eye early can prevent permanent damage to the surface of the eye and therefore help to stop future vision loss.

If symptoms do not improve over time, it is important to consult an ophthalmologist, pharmacist, optician or GP, who will assess the severity of your dry eye and recommend the best treatment for you.

Cationorm® is a unique solution for holding onto hydration

Artificial tears are eye drops used as a replacement for watery tears. Drops that act like real tears and stay in the eye can be the most useful. It is important to find a solution that protects and hydrates the eye and that also supports healing by holding moisture in place.

Cationorm®, by Santen, provides all three and works by restoring moisture and preventing further fluid loss through evaporation. Cationorm® protects and hydrates the eye’s surface, holding hydration into place with its positively-charged cationic emulsion to provide long-lasting symptom relief. With its advanced mechanism, it has shown to support corneal healing in more patients after one week than hyaluronate sodium eye drops achieve in 12 weeks.

A preservative-free option, Cationorm® restores the three layers of the tear film on the eyes (lipid, aqueous and mucin), which are each essential for maintaining eye health and function, and offers relief from eye irritation and discomfort, even for everyday use contact lens wearers.
