Treatment of dry eye

Diagnosis of dry eye is particularly challenging. No single diagnostic test can be performed in a clinic to reliably distinguish individuals with or without dry eye. Furthermore although a variety of diagnostic tests are available, there is no consensus on which combination of tests should be used to define the disease.
There is no known ‘cure’ for Dry Eye.  However dry eye can be treated with artificial tears or in severe cases blocking the punctum with plugs.  The purpose of treatment is to replace and/or enhance the natural tears that your eyes are producing.
Many people who present with dry eye are given with a variety of drops to try.
No one treatment is perfect for everyone. Many people are trying sodium hyaluronate based drops which are quickly establishing themselves as the “gold standard” treatment. There is a lot of evidence to suggest that sodium hyaluronate can have a restorative effect on the anatomy of the eye as well as offer relief from dry eye symptoms.  
Most artificial tears will need to be used as often as necessary to keep the eyes comfortable. The drops can be as frequent as every hour or as little as a few times a day, depending on your needs. Your artificial tear should rehydrate the tear film and lower the elevated tear osmolarity. Oxyal™ contains beneficial electrolytes and is slightly hypotonic which means it has a positive effect on osmolarity.
Some artificial tears have ingredients that create a protective barrier that stays on the eyes’ surface for longer. This may reduce the number of daily applications and replenish moisture so that you feel relief of your symptoms almost immediately. Oxyal™ contains Protector™ that enhances the viscosity of the lubricant whilst helping to keep the existing tears on the eye for longer.
