Treatment Overview
Deep Scleral Trabeculectomy in Korea is a refined, partially penetrating glaucoma surgery designed to enhance aqueous outflow while reducing the risks associated with traditional full-thickness trabeculectomy. This technique involves creating a deep scleral flap and a controlled filtration space without fully entering the anterior chamber, leading to safer pressure reduction with fewer complications.
Korean glaucoma surgeons are highly skilled in deep scleral procedures, using OCT-guided scleral depth mapping, AI-assisted flow prediction, and precision micro-dissection techniques to create a stable, controlled filtration system that lowers intraocular pressure (IOP) while preserving ocular integrity.
Purpose & Benefits
Purpose
- Lower intraocular pressure by enhancing controlled filtration through a deep scleral space.
- Provide an alternative to traditional trabeculectomy with fewer complications.
- Reduce reliance on long-term glaucoma medications.
- Preserve ocular tissue integrity and maintain safer drainage pathways.
Benefits
- Lower Risk of Hypotony: Controlled flow prevents excessively low IOP.
- Fewer Complications: Reduced chance of leaks, infections, and over-filtration.
- Smoother Recovery: Less inflammation and irritation.
- Stable IOP Reduction: Effective long-term drainage with minimal disturbance.
- Enhanced Safety: No full-thickness entry into the anterior chamber.
- Ideal for Patients at Higher Risk: Especially beneficial for those prone to scarring or complications.
Ideal Candidates
Deep Scleral Trabeculectomy in Korea is ideal for:
- Patients with primary open-angle glaucoma (POAG).
- Individuals with mild to moderate glaucoma requiring a safer surgical option.
- Patients who may not tolerate traditional trabeculectomy risks.
- Individuals with high scarring risk or conjunctival limitations.
- Patients seeking long-term pressure control without more invasive surgery.
- Those who did not respond fully to medications or laser therapy.
Possible Risks & Complications
Although safer than full-thickness trabeculectomy, potential risks include:
- Transient elevation or drop in IOP
- Mild postoperative inflammation
- Micro-hyphema
- Scarring of the deep scleral space
- Rare fluid misdirection
- Potential need for adjunctive procedures (e.g., needling)
Korean centers minimize risks with precise depth mapping, anti-scarring therapy, and postoperative monitoring using high-resolution imaging.
Types of Deep Scleral Trabeculectomy Techniques in Korea
Standard Deep Scleral Trabeculectomy
Creates a deep scleral pocket and thin trabeculo-Descemet membrane for filtration.
Implant-Assisted Deep Scleral Surgery
Inserts a collagen or hyaluronic implant to stabilize the filtration space.
Deep Scleral Tunnel Technique
Enhances drainage through a deep scleral tunnel without bleb over-elevation.
Hybrid Deep Scleral + Canaloplasty
Combines internal drainage with Schlemm’s canal dilation for enhanced flow.
Deep Scleral Revision Surgery
Used to restore filtration in previously failed deep scleral procedures.
Surgical Techniques
OCT-Guided Scleral Mapping
Precisely identifies scleral thickness and optimal dissection depth.
Deep Scleral Flap Dissection
Carefully removes deep scleral layers while preserving a thin membrane for filtration.
Trabeculo-Descemet Membrane Exposure
Allows controlled aqueous percolation without full penetration.
Implant or Spacer Placement (Optional)
Prevents collapse of the scleral pocket and maintains long-term filtration.
Canal Expansion (If Combined with Canaloplasty)
Viscoelastic used to dilate Schlemm’s canal and increase outflow.
Anti-Scarring Modulation
Mitomycin-C or 5-FU applied safely to prevent fibrosis.
Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes OCT, visual fields, IOP testing, and scleral thickness analysis.
Step 2 – Surgical Planning
Surgeon selects technique based on anatomy, scarring risk, and glaucoma severity.
Step 3 – Deep Scleral Trabeculectomy
Performed under local anesthesia with precise microsurgical dissection.
Step 4 – Immediate Postoperative Care
Anti-inflammatory drops and IOP monitoring.
Step 5 – Long-Term Filtration Assessment
OCT and clinical follow-ups ensure drainage stability and membrane patency.
Treatment Duration: 25–40 minutes
Setting: Surgical center or hospital
Recovery & After-Care
After-Care Guidelines
- Use prescribed anti-inflammatory and antibiotic drops.
- Avoid eye rubbing and strenuous activity for 1–2 weeks.
- Continue glaucoma medications only if instructed.
- Attend follow-up visits for IOP and filtration monitoring.
Recovery Timeline
- Days 1–3: Mild irritation or redness.
- Week 1: Improved comfort; filtration begins to stabilize.
- Weeks 2–4: IOP reduction becomes consistent.
- Months 1–3: Long-term drainage space fully develops.
Results & Longevity
Expected Results
- Significant IOP reduction comparable to safer forms of trabeculectomy.
- Fewer complications than full-thickness filtration surgery.
- Reduced need for long-term medications.
- Stable, natural filtration through a preserved membrane.
Longevity
- Results often last 5–10 years or longer, depending on scarring tendency.
- Implant-assisted techniques further enhance durability.
- Can be revised or enhanced if needed.
