Treatment Overview
Drainage-Enhanced Trabeculectomy in Korea is an advanced, upgraded form of traditional trabeculectomy that incorporates specialized techniques, implants, or modifications to improve aqueous outflow and enhance long-term filtration success. This approach focuses on strengthening the drainage channel, stabilizing bleb formation, and minimizing fibrosis— the most common cause of trabeculectomy failure.
Korean glaucoma surgeons excel in these enhanced procedures by using OCT-guided filtration planning, AI-based scarring prediction, micro-precision scleral flap design, and innovative drainage implants to achieve safer, more predictable pressure reduction.
Purpose & Benefits
Purpose
- Improve long-term intraocular pressure (IOP) control through optimized drainage.
- Reduce the risk of trabeculectomy failure due to scarring or bleb collapse.
- Create a more stable, durable filtration pathway.
- Offer enhanced safety and predictability for patients with moderate to severe glaucoma.
- Lower dependency on glaucoma medications.
Benefits
- Superior Filtration Stability: Enhanced outflow prevents early bleb collapse.
- Reduced Fibrosis Risk: Anti-scarring strategies improve longevity.
- Lower IOP Levels: Often more effective than standard trabeculectomy.
- Minimized Hypotony: Controlled flow reduces risk of pressure dropping too low.
- Improved Bleb Quality: Natural-looking, functional blebless or low-lying blebs.
- Better Long-Term Success: Ideal for patients with scarring tendencies.
Ideal Candidates
Drainage-Enhanced Trabeculectomy in Korea is ideal for:
- Patients with moderate to advanced glaucoma requiring strong IOP reduction.
- Individuals with high scarring risk, such as younger patients or those with secondary glaucoma.
- Patients with failed previous trabeculectomy needing a more advanced approach.
- Individuals needing filtration support due to thick Tenon’s capsule or conjunctival fibrosis.
- Patients who require long-term stability and want to avoid repeat surgeries.
Possible Risks & Complications
Although optimized for safety, potential risks include:
- Temporary IOP fluctuation
- Mild irritation or inflammation
- Small hyphema
- Fibrosis or scarring affecting flow
- Rare bleb leak
- Transient blurred vision
Korean surgeons minimize these risks using imaging-guided flap positioning, customized anti-scarring regimens, and precise drainage implant insertion.
Types of Drainage-Enhanced Trabeculectomy in Korea
Implant-Assisted Trabeculectomy
Insertion of collagen, hyaluronic, or gel implants to maintain filtration space.
Scleral Spacer–Enhanced Trabeculectomy
Small sponges or polymers prevent collapse of the drainage tunnel.
Canal-Supported Trabeculectomy
Combines trabeculectomy with Schlemm’s canal expansion.
Hybrid Drainage-Enhanced Trabeculectomy
Incorporates visco-canaloplasty, implants, and advanced flap design.
Drainage Ring–Supported Filtration
A circular mini-implant supports uniform bleb distribution.
Anti-Fibrotic–Augmented Drainage Surgery
Uses Mitomycin-C (MMC) or 5-FU in a microdosed, targeted manner.
Surgical Techniques
High-Resolution OCT Planning
Maps scleral depth, conjunctival thickness, and outflow resistance points.
AI-Assisted Scarring Prediction
Determines ideal location and technique to avoid fibrosis.
Precision Scleral Flap Construction
A partial-thickness flap provides controlled aqueous flow.
Implant or Spacer Insertion
Placed beneath the scleral flap to prevent collapse and maintain flow.
Trabecular Block Removal
Creates a new drainage pathway for aqueous humor.
Peripheral Iridectomy (When Needed)
Prevents iris blockage of the filtration site.
Targeted Anti-Scarring Therapy
MMC/5-FU applied in controlled doses for long-term success.
Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes IOP measurement, OCT imaging, visual fields, and conjunctival assessment.
Step 2 – Surgical Planning
Surgeon selects the optimal drainage-enhancing method based on anatomy and risk factors.
Step 3 – Drainage-Enhanced Trabeculectomy
Performed under local anesthesia using implants or modified flap techniques.
Step 4 – Immediate Postoperative Care
Anti-inflammatory drops used; IOP monitored closely.
Step 5 – Long-Term Follow-Up
Regular visits ensure filtration stability and implant positioning.
Treatment Duration: 30–45 minutes
Setting: Surgical center or hospital
Recovery & After-Care
After-Care Guidelines
- Use prescribed drops for several weeks.
- Avoid rubbing the eye or exposing it to unclean water.
- Limit strenuous activity during early healing.
- Continue medications only if instructed.
- Attend all follow-up visits for IOP and bleb monitoring.
Recovery Timeline
- Days 1–3: Mild swelling and discomfort.
- Week 1: Implant or enhanced space stabilizes; filtration begins.
- Weeks 2–4: IOP becomes more consistent; bleb shape improves.
- Months 1–3: Long-term drainage channel fully established.
Results & Longevity
Expected Results
- 30–60% reduction in intraocular pressure.
- More predictable and stable filtration compared with standard trabeculectomy.
- Reduced dependence on glaucoma medications.
- Strong bleb formation with lower complication risks.
Longevity
- Results commonly last 10–20 years or more, depending on patient tissue response.
- Korean implant-assisted techniques significantly extend durability.
- Future revisions, if needed, are easier due to preserved tissue architecture.
