Lacrimal Duct Obstruction Clinical Trial

Official title: Multi-center Clinical Study of Low Temperature Plasma Ablation Combined With Lacrimal Duct Catheterization in the Treatment of Lacrimal Duct Obstructive Diseases

Status Recruiting

Clinical Trial Summary

To compare the clinical effects of low temperature plasma ablation combined with lacrimal duct catheterization and YAG lacrimal duct laser combined with lacrimal duct catheterization in the treatment of lacrimal duct obstruction

Clinical Trial Description

Low-temperature plasma technology has developed rapidly in recent decades and is now widely used in ophthalmology, otolaryngology, orthopedics, urology and other fields .The low-temperature plasma surgery system relies on a 100kHz radio frequency electric field to excite normal saline (0.9% NaCl) to generate plasma energy, and relies on a 50-100 μm plasma layer generated at the front of the plasma knife to perform precise cutting, ablation and hemostaxy. But the application of this technique in the field of lacrimal duct still needs the accumulation of clinical experience.This study was aimed to compare the clinical effects of low temperature plasma ablation combined with lacrimal duct catheterization and YAG lacrimal duct laser combined with lacrimal duct catheterization in the treatment of lacrimal duct obstruction ;
