I've had them in my bottom tear ducts before and it helped a lot. My doctor put them in again last week when he lanced those cysts on my eyeball. He put in upper and lower in my right eye and lower only in my left (my right eye is a lot dryer than my left). The doctor said I would have increased tearing (for obvious reasons) but for anyone who has had them before, does the amount of tearing decrease over time? I have to wipe my eye constantly. If it doesn't lighten up I'm going to have him take out the upper plug.
