Ocular lubricant
"I have been using Restasis drops for approx 5 years, but still suffer from severe dry eyes.  My doctor gave me a sample of Fresh Kote to try.  At first the stinging alarmed me, but within a few minutes my eyes felt refreshed.  These are the first drops that I've actually felt some relief.  I haven't had to purchase them yet, but they can't be any more expensive then Restasis drops."
