Intraoperative optical coherence tomography for Ab externo PreserFlo MicroShunt in glaucoma surgery

Area of Science:

• Ophthalmology
• Surgical Innovation
• Medical Imaging

Background:

• Glaucoma management requires precise surgical techniques for effective intraocular pressure (IOP) reduction.
• Accurate placement of glaucoma drainage devices like the PreserFlo MicroShunt (PMS) is crucial for surgical success and minimizing complications.

Purpose of the Study:

• To introduce and evaluate an innovative surgical technique for PreserFlo MicroShunt (PMS) implantation.
• To utilize intraoperative optical coherence tomography (iOCT) for enhanced visualization and precise positioning of the PMS during surgery.

Main Methods:

• Retrospective analysis of nine glaucoma patients undergoing PMS implantation.
• Intraoperative optical coherence tomography (iOCT) guided the determination of the transscleral route, anterior chamber entry, and device trajectory.
• Evaluation of intra- and postoperative outcomes and complications.

Main Results:

• All nine patients achieved a significant reduction in intraocular pressure (IOP) post-surgery.
• The iOCT-guided technique allowed for immediate intraoperative adjustments, ensuring precise and safe PMS implantation in all cases.
• No notable complications were reported during the study period.

Conclusions:

• The integration of iOCT refines PMS implantation by improving intraoperative visualization and positioning accuracy.
• This innovative application of iOCT has the potential to enhance surgical outcomes for both experienced and junior ophthalmic surgeons.
• iOCT-guided PMS implantation offers a precise and safe method for glaucoma management.
