Topical anesthesia for 25-gauge vitrectomy is safe and effective in selected cases, with minimal pain reported during the procedure. Further studies are needed to confirm these findings in a larger patient cohort.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Traditional vitrectomy often uses local or general anesthesia.
  • Minimally invasive ophthalmic surgery seeks to reduce patient discomfort and recovery time.

Purpose of the Study:

  • To assess the safety and efficacy of transconjunctival 25-gauge vitrectomy performed solely under topical anesthesia.
  • To evaluate patient-reported pain and procedural outcomes.

Main Methods:

  • A pilot study involving 7 patients undergoing 25-gauge vitrectomy for conditions including vitreous hemorrhage, retained cortex, and endophthalmitis.
  • Anesthesia was administered via an anesthetic-soaked pledget; pain was graded on a 0-4 scale.
  • Patients were assessed immediately post-surgery, at day one, and one week.

Main Results:

  • All patients experienced no pain during the vitrectomy itself, with mild pain (grade 2) reported by some during sclerotomy placement.
  • No sedation was required, and no inadvertent eye movements occurred.
  • Five out of seven eyes had favorable outcomes, with no procedure-related complications observed.

Conclusions:

  • Topical anesthesia presents a safe and effective alternative to infiltrative anesthesia for carefully selected 25-gauge vitrectomy patients.
  • Larger studies with extended follow-up are warranted to validate these preliminary results.
