Probing to Open Blocked Tear Ducts

To open a child’s block tear duct an eye
surgeon may probe the tear duct. The surgeon will dilate or widen the
puncta with an instrument then he or she will gently pass a very thin probe
through the puncta into the tear drainage system, then into the back of the nose
this may clear the blocked duct allowing tears to drain again the surgeon will
remove the probe and check to see that the duct is open.
