The cost of lacrimal duct exploration surgery is basically around$50-$100, which is very inexpensive. The costs required for lacrimal duct probing are anesthesia, which is now surface anesthesia, and the cost of surface anesthesia is$5. The other is tear dilation, the cost of tear dilation is 5-10 dollars, and tear duct probing, the cost of tear duct probing is about 30 dollars. If you need to put a stent in after the lacrimal duct exploration, the cost of the stent is more expensive, and the cost of the lacrimal duct stent is more than$1000. In addition, the lacrimal ducts need to be flushed once a week after the lacrimal duct probing procedure to ensure that the effect of the lacrimal duct probing is long lasting. If the tear duct becomes blocked again after 3-4 flushes, you may need to undergo the appropriate surgical treatment.
