punctal valgus correction

The punctal valgus correction procedure is suitable for mild valgus of the lower punctum, and the lower punctum valgus caused by severe lower scar valgus should be corrected for valgus valgus. Treating diseases: valgus Indication The punctal valgus correction procedure is suitable for mild valgus of the lower punctum, and the lower punctum valgus caused by severe lower scar valgus should be corrected for valgus valgus. Contraindications 1. There is inflammation in the gingival margin. 2. The conjunctiva has acute inflammation. Preoperative preparation Rinse the conjunctival sac with saline. Surgical procedure 1. Electric cauterization method (Electtrocautery) (1) Flip the lower jaw and expose the conjunctiva. (2) Using a thick electrode needle of an electric heat permeable device, a row of cauterization is performed about 25 mm behind the puncture point. The depth of the electrode acupuncture reaches a shallow layer of the tarsal plate. The distance between the burning points is 2 mm, which is a radial half-circle puncture. The number of burning points depends on the degree of eversion. Apply antibiotic eye ointment to the conjunctival sac and cover the eye pad. 2. Conjunctiviplasty surgery is best performed under a surgical microscope. (1) Flip the lower jaw, expose the sacral conjunctiva, and pull the lower jaw with a small hook. (2) At the conjunctiva of about 25mm after the puncture, use a knife to make a fusiform shape, a width of about 2mm, a length of about 5mm, and a depth of the incision. The widest part of the fusiform is just at the punctum. One side, the other side is cut, and finally the fusiform conjunctiva is removed simultaneously with the tarsal tissue, and the horizontal suture of the incision is made. 3. If the valgus is heavier, the length and width of the resected tissue can be appropriately increased, or a ulnar cut can be made under the lower punctum, and then the ends of the puncture can be made into a long triangular conjunctiva and tarsal tissue resection. . 4. The incision is intermittently sutured. Apply antibiotic eye ointment and cover the eye pad.
