Summary
Topical anesthesia with benoxinate hydrochloride 0.4% offers effective pain control for pterygium surgery. Most patients experienced mild discomfort, with only a few requiring additional anesthetic injections during the procedure.
Area of Science:
- Ophthalmology
- Surgical Anesthesia
Background:
- Pterygium surgery traditionally relies on injected anesthetic agents.
- Evaluating alternative anesthesia methods is crucial for patient comfort and procedural efficiency.
Purpose of the Study:
- To assess the efficacy of topical benoxinate hydrochloride 0.4% as a sole anesthetic for pterygium excision.
- To determine the rate of additional anesthetic requirements during the procedure.
Main Methods:
- 150 patients with pterygium underwent surgical excision.
- Topical benoxinate hydrochloride 0.4% was administered every minute for 10 minutes prior to surgery.
- Anesthetic drops were reapplied every 5 minutes intraoperatively as needed.
Main Results:
- The average pterygium excision time was 25 minutes.
- Only 3 out of 150 patients required intraoperative anesthetic injections.
- 115 patients reported mild discomfort, with some requesting supplemental anesthesia.
Conclusions:
- Topical benoxinate hydrochloride 0.4% provides adequate anesthesia for pterygium surgery.
- This method reduces the need for invasive anesthetic injections.
- Effective pain management was achieved in the majority of patients.
