bridge conjunctival flap occlusion

Bridge conjunctival flap occlusion is a bridge-like conjunctival flap that covers the wound or tissue defect through the cornea or sclera, as well as refractory corneal ulcers and corneal cramps to prevent infection and promote healing. At present, due to the extensive development of ocular surgery under the microscope, this operation has not been clinically applied. Treating diseases: corneal ulcers Indication Bridge conjunctival flap occlusion is suitable for: Corneal ulcer perforation and corneal penetrating injury combined with corneal tissue defects, and no corneal transplantation conditions. Surgical procedure 1. Cut the bulbar conjunctiva from 12 to 6 o'clock along the limbus. According to the size of the corneal wound, it should be 2 mm wider than the lesion area. Make a second incision on the outside of the first incision. The two incisions are parallel to each other. 2. Peel the subconjunctival tissue and make a bridge-like conjunctival flap. Treat the corneal lesion area and fix it on the surface of the sclera near the limbus with silk thread.
