Treatment Overview
Kahook Dual Blade Goniotomy in Korea is a minimally invasive glaucoma surgery (MIGS) that removes diseased trabecular meshwork to improve aqueous humor outflow and effectively lower intraocular pressure (IOP). The Kahook Dual Blade is a precision-engineered, single-use microsurgical blade designed to excise a clean strip of trabecular tissue without damaging surrounding structures.
Korean ophthalmology centers are global leaders in angle-based MIGS procedures, using OCT-guided planning, AI-enhanced incision mapping, and high-definition goniovisualization to ensure precise and safe KDB goniotomy for patients with open-angle glaucoma.
Purpose & Benefits
Purpose
- Increase aqueous outflow through Schlemm’s canal by removing obstructive trabecular meshwork.
- Reduce IOP in patients with mild to moderate open-angle glaucoma.
- Decrease reliance on glaucoma medications.
- Serve as a safe alternative or complement to laser trabeculoplasty and other MIGS.
Benefits
- Precise TM Removal: Dual-edged blade removes meshwork cleanly and efficiently.
- Minimally Invasive: No external incisions or bleb formation.
- Fast Recovery: Patients typically resume activities quickly.
- Medication Reduction: Many patients significantly reduce eye drop use.
- Compatible With Cataract Surgery: Enhances outcomes when performed during phacoemulsification.
- Low Risk Profile: Minimal inflammation and fewer complications than traditional surgery.
Ideal Candidates
KDB goniotomy in Korea is ideal for:
- Patients with mild to moderate primary open-angle glaucoma (POAG).
- Individuals who are undergoing cataract surgery and want improved IOP control.
- Patients who need early surgical intervention before severe disease.
- Individuals with pseudoexfoliative or pigmentary glaucoma.
- Those who did not respond fully to SLT or medications.
- Patients preferring a safe, angle-based procedure with natural outflow preservation.
Possible Risks & Complications
KDB goniotomy is very safe, but may involve:
- Mild hyphema (small blood presence)—usually resolves quickly.
- Transient IOP fluctuations
- Temporary blurred vision
- Mild inflammation
- Rare scarring of Schlemm’s canal
Korean ophthalmologists minimize complications through AI-calibrated incision arc planning, ultra-precise visualization, and postoperative anti-inflammatory care.
Types of KDB Procedures in Korea
Standalone KDB Goniotomy
Performed via micro-incision for pure trabecular meshwork removal.
KDB With Cataract Surgery
Common combined procedure offering improved long-term IOP reduction.
Extended KDB Goniotomy
Larger arc of TM removal for enhanced drainage.
Hybrid KDB + Canaloplasty / GATT
Combines mechanisms for deeper and more sustained pressure lowering.
Surgical Techniques
High-Definition Goniovisualization
Angle imaging and a gonioprism allow precise identification of trabecular meshwork.
Micro-Incision Access
A tiny corneal incision provides access to the anterior chamber.
Dual Blade TM Excision
KDB removes a strip of trabecular meshwork cleanly, preserving Schlemm’s canal.
Controlled Incision Arc
Surgeon excises 90–180° of TM based on glaucoma severity.
AI-Enhanced Targeting
Assists in selecting the optimal outflow segments for excision.
Post-Procedure Canal Assessment
OCT imaging ensures adequate canal patency and flow.
Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes IOP measurement, OCT imaging, visual fields, and angle assessment.
Step 2 – Surgical Planning
Determines arc length, combination procedure options, and energy-free approach.
Step 3 – KDB Goniotomy
Performed through micro-incision; precise TM removal restores outflow.
Step 4 – Immediate Postoperative Care
Anti-inflammatory drops started; IOP monitored closely.
Step 5 – Follow-Up Monitoring
IOP response and canal stability assessed over weeks and months.
Treatment Duration: 10–20 minutes
Setting: Outpatient MIGS surgical suite
Recovery & After-Care
After-Care Guidelines
- Use anti-inflammatory drops for 2–4 weeks.
- Avoid strenuous activity and eye rubbing.
- Continue glaucoma drops only if recommended by your doctor.
- Attend scheduled follow-ups for IOP and angle evaluation.
Recovery Timeline
- Days 1–3: Mild redness or blood layering (hyphema), but improving quickly.
- Week 1: Vision stabilizes; significant IOP reduction begins.
- Weeks 2–4: Outflow pathways remain open; results stabilize.
- Months 1–3: Maximum IOP-lowering effect achieved.
Results & Longevity
Expected Results
- 20–40% reduction in intraocular pressure.
- Significant reduction in or elimination of glaucoma medications.
- Improved aqueous outflow with natural drainage restored.
- Enhanced long-term control when combined with cataract surgery.
Longevity
- Results typically last years, depending on healing and glaucoma severity.
- Repeat MIGS or additional procedures can be performed as needed.
- Korea’s imaging-guided techniques optimize long-term outcomes.
