If the blockage is mild, a tear duct dilator can be used to dilate the tear duct, and a tear duct probe can be used after the dilation. If the blockage is mild, it can basically be kept open. If the lacrimal punctum is partially blocked and the length of the lacrimal duct is relatively long, simple probing is not feasible and surgery should be considered. A triangular incision of the lacrimal dots or a lacrimal laser can be used to cauterize the lacrimal ducts and completely open the blocked lacrimal dots and ducts with the laser. After opening, viscosupplementation or ophthalmic ointment can be injected regularly into the channel, and in some cases, a lacrimal duct stent may need to be placed to keep the lacrimal duct open for future blockage.
