What is the First Line of Defense Against Dry Eyes?
Preservative-free artificial tears are the first line of defense, as preservatives are a contributing factor of dry eyes. Artificial tears may provide a temporary symptomatic relief, but many patients will require a medication called Restasis. Restasis is a prescription medication that increases the production of your own tears and can significantly decrease the symptoms of dry eyes. You will benefit from increased tear production as long as you are using Restasis. Restasis requires 90 days to reach its full potential, and you will notice an improvement in your symptoms of dry eyes in a few weeks after starting Restasis, with the full in about 90 days. The most common side effect of Restasis is a burning sensation that one out of five patients experience. This burning dissipates with time in the majority of patients.
