    Abstract:
    AIM: To present our experience with single-stage adjustable strabismus surgery (SSASS) under topical anesthesia and propofol. MATERIALS AND METHODS: Sixteen patients who either had diplopia before the surgery or were at risk of developing diplopia after the surgery were selected for this operation after evaluating their tolerance for an eyelid speculum. Recession of the lateral recti, recession, resection and advancement of the medial recti, anteriorization of the inferior oblique and marginal myotomy to the superior rectus were the procedures done under topical anesthesia and propofol. The operations were done in two phases; in the first phase, the patients were sedated for 10 minutes with intravenous propofol (2 mg/kg) and the operation was done under topical anesthesia with 2% lidocaine. In the second phase, the patients were conscious and the adjustments were made. RESULTS: None of the patients complained of significant pain during the surgery. No complications occurred during and after the procedure and no patients had diplopia during the postoperative follow-up. CONCLUSIONS: Single-stage adjustable surgery is practical and avoids the risks of regional and general anesthesia. The only disadvantage is the pain that some patients experience. We found that it is feasible to use propofol for this surgery; it provides deep sedation and prevents pain from being felt during the operation, and its short elimination half-life provides rapid awakening for the adjustment phase.
