Area of Science:

  • Ophthalmology
  • Surgical Anesthesia

Background:

  • Cataract surgery under local anesthesia can induce visual sensations.
  • These sensations have been under-investigated until recently.
  • This review examines recent studies, clinical significance, and mitigation strategies.

Discussion:

  • Patients report diverse visual phenomena, including light perception, movements, colors, and surgical elements.
  • A significant percentage (7.1-15.4%) find these experiences frightening.
  • Fear and anxiety can lead to patient uncooperativeness and physiological stress responses.

Key Insights:

  • Intraoperative visual experiences during cataract surgery are common.
  • A notable portion of patients find these experiences distressing, leading to anxiety.

  • Patient distress can negatively impact surgical outcomes and patient safety.

    • Outlook:

    • Ophthalmologists must address patient visual experiences during informed consent.
    • Preoperative counseling on potential intraoperative visuals is crucial.
    • Further research into methods to reduce intraoperative vision is warranted.
