The effect of sub-Tenon versus topical anesthesia on pupil responses in the early postoperative period after cataract surgery

Puntos clave

• This research aims to evaluate the effects of sub-Tenon's versus topical anesthesia on pupil responses after cataract surgery.
• Compared sub-Tenon's and topical anesthesia in cataract surgery
• Measured pupillary dynamics one week postoperatively
• Evaluated autonomic pupillary response after both types of anesthesia
• No clinically significant changes in pupillary dynamics observed with sub-Tenon's anesthesia
• Sub-Tenon's anesthesia is suggested as a safe alternative to topical anesthesia regarding pupil response
