The blood serum drops work great for me. Here is a reply I recently posted about my experience.
I had my AN in 85 and a recurrence in 93. My eye seems to be getting worst with age. I have had the lower lid lift, 5-6 gold weights in and out of my upper lid and now have two with a total of 3 g. I can't wear the Sclera lens for some reason.
But two things that have helped me over the past year. First was having both my tear ducts plugged. I have had the upper one plugged for some time now but the lower one was plugged a year ago. Now my eye waters sometime. Second best thing I did was have the blood serum eye drops made. It is just amazing how much they help. When I don't have them I am using the Natural Tears on the average 1-2 times an hour. With the Blood drops it's 4-5 times a day. Even when my eye waters, like it does now with the tear duct plugs the quality of the tears that is produced isn't as good as the blood drops, according to my DR.
I can't stop doing what I do because of my severe dry eye (I work outside and ride Motorcycle) so over the past 31 years I am always looking for something better to help with my eye.
It's sometimes hard to find someone to make the blood serum drops and they are not cheap, but what a difference. I have to drive3 1/2 hours one way to get mine at a price of $200 for a 15 week supply and I don't get there as regularly as I should. Good luck finding help with your dry eye, I feel your pain. Jim
