Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Surgical Techniques

Background:

  • Refractive corneal lamellar surgery modifies corneal shape using a microkeratome.
  • Traditional sutures can cause irregular astigmatism and visual deficits due to disk tearing or decentration.

Purpose of the Study:

  • To introduce and evaluate a new suture technique for refractive corneal lamellar surgery.
  • To address complications associated with traditional suturing methods.

Main Methods:

  • A novel suture technique, the BRA suture, based on the overlay concept was developed.
  • The BRA suture is anchored at four points in the corneal periphery.
  • The technique was applied in over 300 refractive corneal lamellar procedures.

Main Results:

  • Elimination of iatrogenic irregular astigmatism.
  • Significant reduction in corneal scarring.
  • Decreased surgical time, accelerated visual recovery, and increased patient comfort due to early suture removal.

Conclusions:

  • The BRA suture is effective, simple, and safe for refractive corneal lamellar surgery.
  • It is considered an ideal suture for these procedures.
  • The technique minimizes complications and improves patient outcomes.
