Randomized Controlled Trial Clinical Trial
Comparison of sub-Tenon's anaesthesia by different delivery techniques in cataract surgery.
To compare the analgesic effects of three different delivery techniques of sub-Tenon's anaesthesia in cataract surgery by assessing patients' response to the visceral stimulus. ⋯ The three anaesthetic delivery methods of sub-Tenon's anaesthesia possess similar and reasonable analgesic effects in cataract surgery, but may not block visceral stimuli completely.
