I have been trying the blood serum drops since Thanksgiving and they seem to work better than any drops I have tried in the past 30 years. The problem I have is that I also had my upper tear duct plugged at the same time. This has relieved my dry eye before I left the Doctors office. So I can't tell if it's the drops or duct plug.
I now have too much tearing in my eye and making my vision blurry, never thought it possible. Normally I just wipe it dry and it's good for a little while, but when working there is way to much tearing. Going to see a local eye Doctor and see if they can replace the lower duct plug with a Flow control tear duct plug. Something my eyelid Doctor suggested I might need if this didn't work out. I think this would be better because when I put the serum drop in my eye it normally runs out of my eye.
And those drops aren't cheap, After $65 to take blood and spin the plasma out the compounding pharmacy charged $200 to make the drops. I got 15 bottles with less than 6 ml/bottle, that works out to about 3 ounces total eye drops. The drops have to be stored in the freezer and used up in seven days after you thaw one out. So I have 15 weeks of drops to try. I hope I have the new tear duct plug in before they are gone. And if I what to stay on the drops I have to drive 3 1/2 hours to have them made again, I have checked there is know where else closer.
Hope this helps anybody thinking about trying the drops or both tear ducts plugs.
