Low Temperature Plasma Ablation Combined Lacrimal Duct Catheterization in the Treatment of Lacrimal Duct Obstructive

The operation used a tear point dilator to expand the patient's upper and lower tear points, YAG laser/low-temperature plasma knife was used to clear the obstructed site of the patient, and normal saline was used to rinse to ensure the patency of the lacrimal passage. The silicone lacrimal duct drainage tube was selected to put the lacrimal duct drainage tube in the upper and lower lacrimal dots of the patient, and the metal probe was removed after using a crochet, and the drainage tube was moderately pulled upward from the center of the upper and lower lacrimal dots to facilitate the smooth passage of the drainage tube through the whole lacrimal duct and achieve the purpose of dredging the blocked site again. Adjust the length of the drainage tube in the nasal vestibule and leave it in the nasal cavity.
