What this Trial Is About
To study the effect of Photosensitive hydrogel used for suture free anastomosis of lacrimal cyst and nasal mucoperiosteal flap in endoscopic nasal dacryocystostomy, and evaluate its adhesion to lacrimal cyst and nasal mucoperiosteal flap, promoting wound healing, forming a good anastomosis, preventing postoperative anastomosis and shortening operation time. Twenty patients with chronic dacryocystitis were randomly divided into photosensitive hydrogel group and suture group.Symptoms and nasal endoscopy were followed up 2, 6, and 12 weeks after surgery for both groups. And also adverse events were recorded at each follow-up.
