A novel conjunctival retractor enhances surgical exposure of the scleral bed during filtering procedures. This instrument minimizes tissue damage and allows for smaller incisions, improving surgical outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Instrumentation

Background:

  • Filtering surgery for glaucoma requires adequate exposure of the scleral bed.
  • Current instruments like non-toothed forceps or Weck cell sponges may cause crush injury or require larger incisions.

Purpose of the Study:

  • To introduce and evaluate a new conjunctival retractor designed for improved scleral bed exposure during filtering surgery.

Main Methods:

  • A novel conjunctival retractor was utilized during filtering surgery.
  • The retractor's ability to elevate conjunctiva and expose the scleral bed was assessed.
  • Comparison of incision size with conventional instruments was noted.

Main Results:

  • The new retractor provides desired exposure of the scleral bed.

  • It elevates conjunctiva without causing crush injury.
  • Excellent scleral bed exposure is achieved with smaller incisions compared to traditional methods.

    • Conclusions:

    • The new conjunctival retractor offers a superior method for achieving scleral bed exposure in filtering surgery.
    • It facilitates better visualization and potentially reduces surgical trauma.
    • The instrument's maneuverability allows for adaptable surgical site exposure.
