Intraoperative Adjustable Suture Strabismus Surgery Under Topical and Subconjunctival Anesthesia

Abstract

To assess the postoperative surgical results of intraoperative adjustable suture strabismus surgery under topical and subconjunctival anesthesia. 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. 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%. 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.
