Treatment Overview
Endoscopic Trabeculectomy Revision in Korea is a specialized, minimally invasive procedure used to repair, restore, or enhance a failing trabeculectomy by using an endoscope to visualize internal structures that are otherwise difficult to access. This technique allows surgeons to precisely assess and treat scarring, flap obstruction, or internal bleb dysfunction without large incisions.
Korean glaucoma centers leverage state-of-the-art micro-endoscopic cameras, OCT-assisted planning, AI-based fibrosis modeling, and precision microsurgical tools to safely rejuvenate filtration, reduce intraocular pressure (IOP), and extend the lifespan of the original trabeculectomy.
Purpose & Benefits
Purpose
- Restore filtration in a trabeculectomy that is failing due to scarring or blockage.
- Address internal drainage pathway issues using direct visualization.
- Avoid the need for a full surgical redo or more invasive glaucoma interventions.
- Improve long-term IOP control and prevent vision loss.
- Correct bleb dysfunction in a highly targeted manner.
Benefits
- Direct Internal Visualization: Endoscope provides real-time imaging of flap, scleral tunnel, and filtration tissue.
- Minimally Invasive: Small incisions reduce trauma and recovery time.
- Precise Scarring Removal: Scar tissue is addressed with accuracy not possible with external-only methods.
- Restores Original Trabeculectomy Function: Salvages the first surgery and preserves future options.
- Reduced Complication Rates: More controlled than open revision.
- Fast Recovery: Less inflammation and shorter healing period.
Ideal Candidates
Endoscopic Trabeculectomy Revision in Korea is ideal for:
- Patients with a failing or partially failed trabeculectomy.
- Individuals with internal scarring, flap obstruction, or collapsed filtration pathways.
- Patients experiencing elevated IOP due to bleb dysfunction.
- Those who previously had needling but require more precise correction.
- Individuals who want to avoid more invasive surgeries like tube shunt implantation.
- Patients with encapsulated, fibrosed, or flat blebs unresponsive to medical treatment.
Possible Risks & Complications
While safer than open revision or repeat trabeculectomy, risks may include:
- Mild postoperative inflammation
- Temporary IOP fluctuations
- Small hyphema
- Minor conjunctival swelling
- Scar tissue recurrence (rare)
- Risk of bleb leak in advanced cases
Korean surgeons minimize risks using high-definition endoscopy, microdissection tools, and anti-scarring adjuvants.
Types of Endoscopic Trabeculectomy Revision in Korea
Endoscopic Scar Tissue Removal
Precise removal of fibrotic tissue blocking the trabeculectomy flap or ostium.
Endoscopic Flap Reconditioning
Re-shaping or freeing a stuck scleral flap under direct visualization.
Endoscopic Sclerostomy Enlargement
Opening or widening the internal drainage channel for improved outflow.
Endoscopic Membrane Excision
Removal of membranes that form beneath the filtration site.
Endoscopic Bleb Rejuvenation
Restores filtration by treating internal adhesions and reestablishing flow.
Combined Endoscopic Revision + MMC/5-FU
For difficult cases with severe scarring or previous surgical failure.
Surgical Techniques
High-Resolution Micro-Endoscope
Inserted through a micro-incision to visualize internal filtration structures.
AI-Guided Planning
Identifies likely zones of failure and predicts surgical outcomes.
Micro-Incisional Access
Allows controlled access to the filtration site with minimal tissue disruption.
Precision Scar Removal
Laser or micro-tools used to break adhesions and reopen the drainage channel.
Scleral Flap Optimization
Internal contour adjustments improve outflow without external dissection.
Anti-Scarring Modulation
Application of MMC or 5-FU to prevent re-fibrosis.
Treatment Process in Korea
Step 1 – Detailed Evaluation
OCT, ultrasound biomicroscopy (UBM), IOP measurement, and bleb morphology assessment.
Step 2 – Surgical Planning
Endoscopic pathway and scarring targets are identified.
Step 3 – Endoscopic Trabeculectomy Revision
Performed under local anesthesia using micro-endoscopic visualization.
Step 4 – Immediate Postoperative Care
Anti-inflammatory and anti-scarring drops are used; IOP monitored.
Step 5 – Long-Term Follow-Up
Regular appointments ensure stable filtration and prevent re-scarring.
Treatment Duration: 20–40 minutes
Setting: Outpatient surgical center
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic and anti-inflammatory drops consistently.
- Avoid eye rubbing and heavy activities for 1–2 weeks.
- Protect the eye from contamination and water during early healing.
- Attend follow-up visits for IOP and bleb evaluation.
- Report sudden pain or decreased vision immediately.
Recovery Timeline
- Days 1–3: Mild discomfort and temporary blurred vision.
- Week 1: Filtration pathway stabilizes; pressure decreases.
- Weeks 2–4: Maturation of revised bleb; scar control assessed.
- Months 1–3: Stable long-term filtration restored.
Results & Longevity
Expected Results
- Significant improvement in aqueous outflow.
- Restored trabeculectomy function without major reoperation.
- Reduced IOP with minimal complications.
- Lower dependence on medications.
- Improved long-term vision preservation.
Longevity
- Results typically last many years, depending on tissue response.
- Endoscopic precision reduces recurrence risk.
- Revision can be repeated or upgraded if needed later.
