A novel adjustable suture technique for trabeculectomy offers improved intraocular pressure (IOP) control post-surgery. This method safely manages IOP without irreversible changes, reducing risks like overfiltration.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Surgery

Background:

  • Current trabeculectomy methods for intraocular pressure (IOP) control often involve irreversible suture alterations.
  • These irreversible methods increase the risk of postoperative overfiltration, a complication impacting surgical success.
  • Effective early postoperative IOP management is crucial for successful glaucoma treatment outcomes.

Purpose of the Study:

  • To describe a new surgical technique utilizing a fully adjustable suture for trabeculectomy.
  • To evaluate the safety and efficacy of this adjustable suture in controlling early postoperative IOP.
  • To assess the potential of this technique to avoid irreversible flap alterations and overfiltration.

Main Methods:

  • Trabeculectomy was performed on eighteen eyes using a novel, fully adjustable suturing technique.

  • Suture tension was incrementally adjusted post-surgery based on IOP measurements and bleb morphology.
  • Digital massage was employed as needed to aid in IOP modulation alongside suture adjustments.

    • Main Results:

    • The adjustable suture technique allowed for precise IOP management in the early postoperative period.
    • Sixteen out of eighteen treated eyes achieved target IOP levels without requiring additional medical or laser therapy.
    • The technique proved safe, demonstrating excellent IOP control without the risks associated with irreversible suture methods.

    Conclusions:

    • The fully adjustable suturing technique offers a safe and effective method for managing early postoperative IOP after trabeculectomy.
    • This innovative approach provides superior IOP control compared to traditional methods, minimizing the risk of overfiltration.
    • Adjustable sutures represent a significant advancement in glaucoma surgery, enhancing patient outcomes and surgical predictability.
