Treatment Overview
Advanced Trabeculectomy Revision in Korea is a specialized surgical approach designed to restore or enhance the function of a previously performed trabeculectomy that has failed or begun to fail due to scarring, fibrosis, or structural complications. Revision procedures may involve bleb needling, flap repair, anti-scarring therapy, or complete surgical reconstruction.
Korean glaucoma specialists are internationally recognized for their advanced revision expertise, using high-resolution OCT imaging, AI-based fibrosis prediction, precision bleb remodeling, and anti-scarring pharmacologic protocols to salvage filtration and securely restore long-term intraocular pressure (IOP) control.
Purpose & Benefits
Purpose
- Restore or improve the function of a compromised trabeculectomy.
- Remove or reduce scar tissue that restricts aqueous drainage.
- Reconstruct or modify the bleb for optimal fluid filtration.
- Prevent the need for more aggressive surgeries such as tube shunts.
- Reestablish long-term IOP reduction.
Benefits
- Preserves Original Surgery: Salvages the existing trabeculectomy rather than replacing it.
- Minimally Invasive Options: Needling and anti-scarring injections often performed in the clinic.
- Avoids Major Surgery: Reduces need for shunts or repeat full trabeculectomy.
- Highly Effective: Korean precision techniques often restore stable IOP for years.
- Targeted Treatment: Custom-tailored based on bleb morphology and scarring severity.
- Improved Long-Term Safety: Controlled flow reduces hypotony and infection risk.
Ideal Candidates
Advanced Trabeculectomy Revision in Korea is ideal for:
- Patients whose trabeculectomy bleb has failed or is failing due to fibrosis.
- Individuals with elevated IOP after trabeculectomy.
- Patients with encapsulated blebs, flat blebs, or poor filtration drainage.
- Those experiencing bleb leaks, flap problems, or scarring around the filtration site.
- Patients wanting to avoid tube shunts or more invasive revisions.
- Individuals with progressive optic nerve damage needing restored pressure control.
Possible Risks & Complications
Although safer than performing a repeat trabeculectomy, revision procedures may include:
- Mild inflammation
- Transient IOP spikes or drops
- Small hyphema
- Conjunctival irritation
- Bleb leakage (rare)
- Scarring recurrence
- Risk of infection (low with Korean protocols)
Korean surgeons minimize risks using OCT-guided bleb diagnosis, anti-fibrotic medications, controlled flap modulation, and intraoperative visualization systems.
Types of Trabeculectomy Revision in Korea
Bleb Needling Revision
Uses a fine needle to break scar tissue and reopen the filtration site.
Anti-Scarring Injection Revision
Mitomycin-C (MMC) or 5-FU injections used to modulate fibroblast activity.
Scleral Flap Re-formation
Reconstruction or tightening/loosening of the flap to regulate flow.
Conjunctival Revision
Repairs thin, leaking, or damaged conjunctiva around the bleb.
Trabeculectomy Re-Do Surgery
A complete repeat trabeculectomy, used only when necessary.
Hybrid Revision (Needling + MMC + Flap Repair)
Combines techniques for complex or heavily scarred blebs.
Surgical Techniques
OCT-Based Bleb Analysis
High-resolution imaging maps bleb thickness, fibrosis depth, and flow pathways.
AI-Guided Scarring Assessment
Predicts areas of failure for precision targeting.
Fine-Needle Bleb Needling
Breaks sub-conjunctival scar tissue to restore outflow.
MMC or 5-FU Modulation
Controls healing and prevents future fibrosis.
Scleral Flap Adjustment
Restores optimal aqueous flow through the original flap.
Conjunctival Repair or Advancement
Improves sealing and prevents leaks.
Postoperative Wound Healing Control
Customized drop regimens to preserve bleb function.
Treatment Process in Korea
Step 1 – Comprehensive Trabeculectomy Evaluation
Includes IOP testing, bleb grading, OCT imaging, and fibrosis assessment.
Step 2 – Custom Revision Planning
Surgeon selects the least invasive method that will achieve stable filtration.
Step 3 – Revision Procedure
Performed in-office (needling) or in a surgical suite (complex revisions).
Step 4 – Immediate Care
Anti-inflammatory and anti-scarring medications applied; IOP monitored closely.
Step 5 – Long-Term Follow-Up
Regular monitoring to maintain bleb stability and avoid re-scarring.
Treatment Duration:
- Needling: 5–10 minutes
- Surgical revision: 20–40 minutes
Setting: Outpatient clinic or surgical center
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotics, steroids, and anti-scarring drops.
- Avoid eye rubbing and strenuous physical activity.
- Keep water and contaminants away from the eye.
- Report sudden pain, vision changes, or excessive redness immediately.
- Attend all follow-up visits to ensure bleb remains functional.
Recovery Timeline
- Days 1–3: Mild discomfort; early filtration returns.
- Week 1: Bleb morphology improves; IOP lowering becomes significant.
- Weeks 2–4: Vision stabilizes; scarring control is monitored.
- Months 1–3: Long-term bleb function established.
Results & Longevity
Expected Results
- Improved aqueous filtration and sustained IOP reduction.
- Preservation of the original trabeculectomy.
