Preservative vs No Preservative
Not all artificial tears are created equal. The preservative is only one component of the artificial tears. While using preservatives too often may be damaging to the ocular surface, some of the modern preservatives are relatively mild. Ultimately, your doctor should have a recommendation of which artificial tears would be best for you. They can titrate their recommendation based on their findings of your ocular surface.
