Peri-menopause, the doctor finally declared and prescribed some drugs. Soon the upheaval toned down but my eyes gradually started stinging and having the ‘sand in my eyes’ feeling. I was sad because this forced me to put away the movies I loved watching. I soon discovered this was dry eye syndrome and eye drops would bring me relief. However, there is such a wide variety of eye drops in the market, I don’t know which one to pick. I believe this Thera tears Extra vs Systane fact-finding mission can give me some insights.

Thera tears Extra uses a vanishing preservative which turns into oxygen and water, when it mixes with the tear film. This is safer than the common preservatives used in many eye drops.
Preserved Systane uses Polyquaternium-1 as a preservative. Though preservatives inhibit bacterial growth and keep eye drops safer, some people are sensitive or even allergic to them. These eye drops may end up causing irritation, redness and more dryness in such people. In high concentrations polyquaternium-1 has been found to be harmful to eye cells.
The active ingredients in Thera tears Extra tries to replicate healthy tears in order to prevent damage that would occur to the cells of the eyes as a result of having dry eyes.
On the other hand, the HP guar in Systane forms a gel-like coating that protects the eye’s damaged cells, improving the healing process.
Osmolarity is the concentration or saltiness of the tears. Hyperosmolarity (high salt concentration) is a common feature in most forms of the dry eye syndrome. It damages eye cells. Thera tears Extra solution is hypotonic (has a lower osmotic pressure). The systane solution is not hypotonic.
Thera tears Extra comes in a 15ml multi reusable bottle whereas the preserved Sytane comes in a 30ml multi-use bottle and the non-preserved in single use vials. To avoid contamination, preservative-free eye drops need to be a single-dose unit (SDU) with a twist-off cap. After taking the one dose, the vial should be disposed.
