Most patients undergoing cataract surgery with sub-Tenon's block anesthesia reported seeing light and colors during the procedure. While generally acceptable, some found the visual experience frightening, necessitating preoperative warnings.

Area of Science:

  • Ophthalmology
  • Anesthesia

Background:

  • Phacoemulsification cataract surgery is a common procedure.
  • Sub-Tenon's block is a frequently used local anesthesia technique for eye surgery.

Purpose of the Study:

  • To investigate the visual experiences of patients during phacoemulsification cataract surgery performed under sub-Tenon's block anesthesia.
  • To assess patient acceptance and emotional responses to intraoperative visual sensations.

Main Methods:

  • A prospective survey was conducted with 121 patients post-surgery.
  • Patients were interviewed on the same day regarding their visual perceptions during the procedure.

Main Results:

  • 81% of patients reported seeing light, 56% saw colors, and 40% perceived movements.
