Treatment Overview
Gonioscopic-Guided Hybrid Trabeculectomy in Korea is a modern, precision-enhanced filtration surgery that combines traditional trabeculectomy principles with real-time gonioscopic visualization and selective angle-based interventions. During this procedure, surgeons use a surgical gonioprism to directly observe the trabecular meshwork, Schlemm’s canal, and angle structures—allowing precise localization, optimized incision, and improved fluid outflow.
Korean glaucoma specialists enhance this hybrid approach with OCT-assisted planning, AI-based outflow mapping, and minimally invasive angle techniques, resulting in safer, more predictable pressure reduction and long-term stability.
Purpose & Benefits
Purpose
- Achieve controlled intraocular pressure (IOP) reduction through a combination of trabeculectomy filtration and angle-based optimization.
- Enhance the accuracy of trabecular block removal through direct visualization.
- Improve surgical outcomes in eyes with complex angle anatomy or previous scarring.
- Reduce long-term reliance on glaucoma medications.
- Provide a hybrid solution for patients requiring more advanced intervention than MIGS alone.
Benefits
- Direct Visualization of Angle Structures: Ensures precise incisions and cleaner filtration pathways.
- Enhanced Filtration Control: Hybrid angle + trabeculectomy approach produces stronger pressure reduction.
- Lower Risk of Complications: Gonioscopic guidance reduces tissue trauma.
- Ideal for Complex Anatomy: Corrects angle abnormalities that affect traditional trabeculectomy success.
- Stable Long-Term Results: Improved bleb quality and better outflow efficiency.
- Reduced Surgical Guesswork: Real-time angle inspection improves accuracy.
Ideal Candidates
Gonioscopic-Guided Hybrid Trabeculectomy in Korea is ideal for:
- Patients with moderate to severe glaucoma needing strong IOP reduction.
- Individuals with complex angle anatomy, such as synechiae, narrow angles, or meshwork irregularities.
- Patients with previous failed trabeculectomy due to angle-related blockage.
- Those with secondary glaucoma, including pigmentary, pseudoexfoliative, or traumatic types.
- Individuals who need more than MIGS but want a refined, controlled trabeculectomy.
- Patients with elevated IOP despite medications or SLT/ALT.
Possible Risks & Complications
Although hybrid and guided approaches reduce risk, possible complications include:
- Mild postoperative inflammation
- Temporary IOP spikes or drops
- Small hyphema
- Angle bleeding (usually self-resolving)
- Scarring of the filtration site
- Rare bleb leak
Korean surgeons minimize these risks using high-definition gonioprisms, micro-incision tools, and targeted anti-scarring therapy.

Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes IOP testing, OCT of the angle, UBM, visual fields, and gonioscopic assessment.
Step 2 – Hybrid Surgical Planning
Determines which angle interventions will complement trabeculectomy.
Step 3 – Gonioscopic-Guided Hybrid Trabeculectomy
Performed under local anesthesia, combining trabeculectomy with angle enhancement.
Step 4 – Immediate Postoperative Care
Includes anti-inflammatory and antibiotic drops with careful IOP monitoring.
Step 5 – Long-Term Follow-Up
Bleb morphology and angle stability monitored with OCT and gonioscopy.
Treatment Duration: 30–50 minutes
Setting: Surgical center or hospital
Recovery & After-Care
After-Care Guidelines
- Use prescribed drops consistently during healing.
- Avoid eye rubbing, bending, or heavy lifting.
- Sleep with protective eyewear during the first week.
- Keep eye dry and avoid contaminated environments.
- Attend follow-up visits for pressure checks and angle evaluation.
Recovery Timeline
- Days 1–3: Mild irritation; early pressure reduction.
- Week 1: Filtration begins stabilizing; angle healing observed.
- Weeks 2–4: Bleb matures and becomes more diffuse.
- Months 1–3: Long-term stability achieved with controlled IOP.
