Intraoperative Adjustable Suture Strabismus Surgery Under Topical and Subconjunctival Anesthesia

Abstract

BACKGROUND AND OBJECTIVE: To assess the postoperative surgical results of intraoperative adjustable suture strabismus surgery under topical and subconjunctival anesthesia. PATIENTS AND METHODS: For 44 patients who had undergone intraoperative adjustable suture technique under topical anesthesia, the deviations were measured preoperatively, at 1 day, 1 month, and 3 months postoperatively, and at the last postoperative follow-up visit. The mean follow-up period was 7.8 months. RESULTS: Thirty-three patients had exotropia and 11 had esotropia. Mean age was 28.8 years. The success rates for exotropia and esotropia at the last follow-up visit were 81.8%. CONCLUSION: Intraoperative adjustable suture strabismus surgery under topical and subconjunctival anesthesia is the recommended surgical technique due to the successful results and various advantages compared with non-adjustable surgery, including the decreased rates of overcorrection or undercorrection that appear immediately after surgery and reoperation. Postoperative "drift" toward the original deviation was observed under longer follow-up periods than other studies.
