Mild dry eyes require only the application of artificial tears, while moderate to severe dry eye treatment often requires a combination of treatments and dialectic therapy. One of these treatments is tear suppository therapy. However, tear suppository treatment must be done carefully and not hastily. In particular, permanent embolization should be done. Unless individual patients with particularly severe dry eye, our hospital generally use sequential therapy: first apply temporary plugs to understand the efficacy and any side effects, but this plugs generally dissolve in a week or so; the second step to use half a year to dissolve the plugs, half a year after the dissolution of symptoms, such as the resurgence of permanent plugs; some heavier patients can also be on the two tear dots in each eye, respectively, a half-year plugs, a permanent plugs, and so half a year after the dissolution of the plugs and then decide This is not only safe but also reduces the cost. Therefore, patients should not be too eager to permanently embolize the tear duct at one time, without a process of observing the efficacy and side effects, which will not be easy to remove when they want to do so.
