A year ago a local doctor helped me by putting some silicone threads in the drainage ducts of my eyes. After a year, it was finally time to take them out. The doctor did so and for a day and a half my eye was super irritated and puffy. One morning I got back from playing racquetball and the pain in my eye was going to drive me insane. Upon close examination of my eye in the mirror I saw the little sharp end of a silicone thread. After many attempts (it isn't easy to poke yourself in the eye with tweezers) I finally grabbed the thread and here is the fruit of my labors.
