Area of Science:

  • Ophthalmology
  • Anesthesiology

Background:

  • Patients undergoing vitreoretinal surgery sometimes experience pain despite local anesthesia.
  • Identifying optimal local anesthesia techniques is crucial for patient comfort.

Purpose of the Study:

  • To determine the most comfortable local anesthesia technique for patients undergoing vitreoretinal surgery.
  • To evaluate the efficacy of different local anesthesia methods in managing surgical pain.

Main Methods:

  • A quasi-experimental design was employed.
  • A convenience sample of 41 patients undergoing vitreoretinal surgery was recruited.
  • A 0-10 visual analog pain scale was used to assess patient comfort levels.

Main Results:

  • The study supported the hypothesis that one local anesthesia technique offered superior comfort.

  • Crucially, sufficient conjunctival anesthesia using 2% lidocaine jelly was found to prevent pain entirely.
  • This suggests a highly effective method for intraoperative pain management.

    • Conclusions:

    • The choice of local anesthesia technique significantly impacts patient comfort during vitreoretinal surgery.
    • Pre-anesthetizing the conjunctiva with 2% lidocaine jelly is a highly effective strategy to ensure a pain-free experience.
    • This finding has direct implications for improving patient care protocols in ophthalmic surgery.
