Nondissolving punctal plugs and punctal occlusion by cautery (application of heat to tear exit duct). If temporary plugs work well, your doctor may move to longer-lasting ones. Or he could choose a procedure called cautery. He'll give you a drug that relaxes you, then use a special tool to burn the opening shut. The scar that forms makes a permanent plug. These measures increase your tear level by blocking the “drainpipe” through which tears usually go from your eye to your nose. Tear plugs are easy to remove, but sometimes they come out on their own or fall down the tear drain. They can make your eyes feel better and lower your need for artificial tears.
