This study introduces a new 20-gauge transconjunctival vitrectomy technique, showing it is beneficial for most eye conditions and versatile with instruments. Method 2, however, showed increased conjunctival edema.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Transconjunctival vitrectomy offers advantages in ocular surgery.
  • Minimally invasive techniques are crucial for patient recovery.

Purpose of the Study:

  • To describe a novel 20-gauge transconjunctival vitrectomy procedure.
  • To evaluate its clinical utility and compare two surgical variations.

Main Methods:

  • Retrospective analysis of 431 patients (433 eyes) undergoing 20-gauge transconjunctival vitrectomy.
  • Comparison of two surgical methods: conjunctiva/sclera combined wounds versus posterior conjunctival openings.
  • Suturing of scleral and conjunctival openings in both methods.

Main Results:

  • The 20-gauge transconjunctival vitrectomy is broadly applicable to various ocular diseases.

  • This technique is not restricted by the choice of intraocular instruments.
  • Surgical method 2 resulted in more conjunctival edema due to perfusion fluid leakage, as cannulas were not used in all ports.

    • Conclusions:

    • The new 20-gauge transconjunctival vitrectomy procedure offers significant benefits for treating a wide range of ocular conditions.
    • Its versatility with intraocular instruments makes it a valuable surgical option.
