Randomized Controlled Trial Comparative Study Clinical TrialEfficacy of lidocaine 2% gel in pterygium surgery.
Anaesthesia during pterygium surgery is usually achieved with local injection of anaesthetic medications. The aim of this study was to determine whether lidocaine 2% gel is an effective topical anaesthetic agent for pterygium surgery. ⋯ In light of these results, we conclude that topical administration of lidocaine 2% gel can be used as an alternative method of anaesthesia in pterygium surgery, especially for patients with needle phobia.
