The reverse 4-throw (RFT) pupilloplasty is a feasible technique for endothelial keratoplasty. This method effectively apposes iris tissue without leaving sutures in the anterior chamber, ensuring successful outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Endothelial keratoplasty requires precise surgical techniques.
  • Pupilloplasty is often necessary during these procedures.

Purpose of the Study:

  • To evaluate the feasibility and applicability of the reverse 4-throw (RFT) pupilloplasty technique.
  • To assess RFT pupilloplasty in the context of endothelial keratoplasty.

Main Methods:

  • The reverse 4-throw (RFT) technique involves using polypropylene and 26-gauge needles to appose iris tissue.
  • Sutures are manipulated to create a knot on the posterior surface of the iris.

Main Results:

  • The RFT pupilloplasty was performed on 11 eyes undergoing endothelial keratoplasty.
  • Anterior segment OCT confirmed no sutures were present in the anterior chamber.

  • No primary graft failure or rejection occurred during follow-up.

    • Conclusions:

    • The reverse 4-throw (RFT) technique is effective for pupilloplasty in endothelial keratoplasty.
    • This method avoids anterior chamber suture or knot presence.
