Abstract

Insights

Sutureless 25-gauge vitrectomy (TSV) offers a safer, faster, and more comfortable alternative for epiretinal membrane (ERM) surgery compared to traditional 20-gauge systems. This advanced technique leads to quicker visual recovery and potentially fewer complications like cataracts.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Retinal Surgery

Background:

  • Idiopathic epiretinal membranes (ERM) affect vision and require surgical intervention.
  • Traditional 20-gauge vitrectomy is a standard treatment for ERM.
  • Evaluating novel surgical approaches is crucial for improving patient outcomes.

Purpose of the Study:

  • To compare the safety and functional outcomes of sutureless 25-gauge vitrectomy (TSV) with standard 20-gauge vitrectomy for ERM treatment.
  • To assess differences in surgical time, complications, and patient recovery between the two techniques.

Main Methods:

  • Prospective evaluation of 46 patients with idiopathic ERM.
  • Group 1: 26 patients underwent transconjunctival sutureless 25-gauge vitrectomy (TSV).
  • Group 2: 20 patients underwent standard 20-gauge vitrectomy. Both groups involved ERM removal and internal limiting membrane (ILM) peeling.

Main Results:

  • No surgery-related complications in either group.
  • TSV group had significantly shorter operating times (15.6 min vs 29.6 min) and less BSS consumption.
  • TSV group showed reduced postoperative discomfort, inflammation, and faster visual acuity improvement.
  • Cataract formation occurred in two eyes in the 20-gauge group.

Conclusions:

  • Transconjunctival sutureless vitrectomy (TSV) is a safe and effective technique for ERM surgery.
  • TSV reduces operating time, minimizes trauma, and lowers postoperative inflammation and discomfort.
  • TSV may lead to a lower incidence of cataract formation and accelerates postoperative recovery.
