Treatment Overview
Needling Revision After Trabeculectomy in Korea is a minimally invasive procedure designed to restore or improve the function of a failing or encapsulated bleb following trabeculectomy. Over time, scar tissue can obstruct the filtration pathway, leading to rising intraocular pressure (IOP). Needling revision breaks down this fibrosis using a fine needle, often combined with anti-fibrotic agents, to re-establish adequate aqueous humor outflow.
Korean glaucoma specialists achieve high success rates using OCT-guided bleb imaging, ultra-fine microneedles, MMC or 5-FU micro-dosing, and AI-based scarring prediction, ensuring safe and precise bleb rejuvenation.
Purpose & Benefits
Purpose
- Reopen a partially or fully failed trabeculectomy bleb.
- Break scar tissue that blocks aqueous outflow.
- Restore target IOP levels without needing repeat surgery.
- Delay or prevent the need for more invasive procedures such as tube shunts.
- Improve bleb morphology and long-term filtration.
Benefits
- Minimally Invasive: No incisions or major surgical trauma.
- Fast and Effective: Immediate restoration of flow in many cases.
- Quick Recovery: Typically performed in-office with minimal downtime.
- Can Be Repeated: Multiple needling sessions possible if required.
- Enhances Longevity of the Original Trabeculectomy: Preserves filtration function.
- Cost-Effective: Less expensive than full revision surgery.
Ideal Candidates
Needling Revision After Trabeculectomy in Korea is ideal for:
- Patients experiencing increasing IOP after trabeculectomy.
- Eyes with encapsulated, flat, or fibrotic blebs.
- Individuals with early bleb failure due to scar formation.
- Patients who cannot undergo more invasive surgery.
- Individuals with partial bleb obstruction at the flap or scleral site.
- Patients who wish to preserve their existing trabeculectomy rather than start over.
Possible Risks & Complications
Needling revision is generally safe, but potential risks include:
- Transient bleeding (subconjunctival hemorrhage)
- Temporary discomfort
- Shallow anterior chamber (rare)
- Short-term IOP spikes
- Micro-leaks
- Infection (rare)
Korean surgeons minimize these risks with gentle microneedle technique, anti-fibrotic control, and real-time imaging.
Types of Needling Revision in Korea
Standard Needling Revision
Basic fibrosis breakdown with a fine needle under slit-lamp guidance.
MMC-Assisted Needling
Mitomycin-C applied during needling to enhance long-term success.
5-FU-Assisted Needling
5-Fluorouracil injected to prevent fibroblast reactivation.
OCT-Guided Needling
High-resolution imaging allows precise targeting of scar tissue.
Hybrid Needling + Bleb Remodeling
Needling combined with conjunctival repositioning or flap lifting.
Laser-Guided Needling Revision
Laser used to soften dense fibrosis before mechanical needling.
Surgical Techniques
Imaging-Based Assessment
OCT or ultrasound maps scar location and bleb wall thickness.
Topical Anesthesia
Ensures comfort during the procedure.
Needle Entry and Scar Lysis
A fine needle (27–30G) breaks adhesions and reopens channels.
Flow Re-Establishment
Surgeon confirms bleb elevation and aqueous movement.
Anti-Fibrotic Injection
MMC or 5-FU injected to maintain long-term patency.
Postoperative Pressure Monitoring
Ensures stable IOP and absence of leak.
Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes slit-lamp exam, IOP measurement, bleb morphology analysis, and OCT imaging.
Step 2 – Revision Planning
Surgeon determines scar patterns and selects the appropriate needling method.
Step 3 – Needling Revision Procedure
Performed at the slit lamp or minor operating room under topical anesthesia.
Step 4 – Immediate Aftercare
Includes antibiotic drops, steroids, and possible eye patching.
Step 5 – Follow-Up Monitoring
IOP and bleb structure monitored over the following weeks.
Treatment Duration: 5–10 minutes
Setting: Outpatient clinic or minor procedure room
Recovery & After-Care
After-Care Guidelines
- Use prescribed anti-inflammatory and antibiotic drops.
- Avoid rubbing the eye or heavy physical activities.
- Attend all follow-up visits for pressure checks and bleb assessment.
- Avoid water exposure for 24–48 hours.
- Report sudden vision changes or pain immediately.
Recovery Timeline
- 24 Hours: Mild redness and small hemorrhages begin to resolve.
- 1–2 Weeks: Bleb stabilizes and IOP becomes steady.
- 1–3 Months: Long-term filtration and bleb remodeling observed.
Results & Longevity
Expected Results
- 20–40% IOP reduction depending on fibrosis severity.
- Restoration of bleb function in many cases.
- Reduced dependence on medications.
- Delay or avoidance of additional surgery.
- Improved bleb shape and filtration quality.
Longevity
- Results last months to years, depending on the patient’s healing profile.
- Repeat needling is possible if scarring recurs.
- Korean anti-fibrotic protocols significantly extend longevity.
