Novel vitreous forceps were developed to simplify membrane removal during eye surgery. These specialized forceps reduce surgical steps and improve outcomes for internal limiting membrane peeling.

Area of Science:

  • Ophthalmology
  • Surgical Instrumentation

Background:

  • Intravitreal membrane removal is crucial for surgical success.
  • Conventional forceps may require multiple insertions, increasing surgical complexity.

Purpose of the Study:

  • To introduce novel multifunction vitreous forceps.
  • To reduce the frequency of forceps insertion during vitreoretinal surgery.
  • To enhance the removal of internal limiting membrane (ILM) and other intravitreal membranes.

Main Methods:

  • Development of multifunction vitreous forceps based on conventional continuous curvelinear capsulorrhexis (CCC) forceps.
  • Incorporation of a 23G shaft with a 500-microm diameter pointed end and a platform.
  • Utilized a pen-hold grip design for reduced hand movement.

Main Results:

  • The forceps facilitate membrane holding via a movable outer sheath and fixed tip with a platform.
  • A sharp point allows for easy initial flap creation.
  • Enables firm grasping of the ILM for precise peeling.

Conclusions:

  • The novel vitreous forceps offer improved functionality for membrane dissection.
  • This instrument design can lead to better surgical outcomes by simplifying procedures.
  • Reduced hand movement and enhanced grip contribute to surgical efficiency.
