Having had the one experience with the one plug in the one lower duct in my right eye, I would not recommend the procedure. Wanted to mention that those ducts are important in providing proper drainage for the tears and in preventing infections. Also, if your eyes are not as dry as mine, there is also the annoying potential risk of tear overflow because you are depending on natural evaporation to dry out your eye. As I said earlier, I was surprised to hear that this is still being done.
