Treatment Overview
Deep Sclerectomy in Korea is an advanced form of non-penetrating Minimally Invasive Glaucoma Surgery (MIGS) designed to lower intraocular pressure (IOP) by enhancing the natural outflow of aqueous humor without fully entering the anterior chamber. Unlike traditional trabeculectomy, deep sclerectomy gently removes part of the scleral tissue to expose the Trabeculo-Descemet’s Membrane (TDM)—a thin, permeable layer that regulates aqueous drainage—resulting in smoother, safer, and more controlled IOP reduction.
Korean ophthalmology centers use micro-scleral dissection, collagen implants, viscodilation, OCT-guided thickness mapping, and AI-based flow prediction to optimize precision and safety. This makes Deep Sclerectomy in Korea significantly less invasive, faster to recover from, and safer than full-penetrating glaucoma surgeries, while still providing strong long-term IOP control.
Purpose & Benefits
Purpose
- Lower intraocular pressure by enhancing natural trabecular and suprachoroidal outflow pathways.
- Create a controlled filtration zone without penetrating the anterior chamber.
- Provide a safer and less traumatic option compared to trabeculectomy.
- Reduce dependency on long-term IOP-lowering medications.
Benefits
- Controlled Outflow: Reduces IOP without sudden pressure drops.
- Non-Penetrating: Lowers risk of hypotony and infection.
- Stable Long-Term IOP Reduction: Excellent outcomes for open-angle glaucoma.
- Improved Safety Profile: Lower complication rates than trabeculectomy.
- Fast Recovery: Minimal inflammation and smoother postoperative healing.
- Reduced Medication Burden: Many patients reduce or discontinue glaucoma drops.
Ideal Candidates
Deep Sclerectomy in Korea is ideal for:
- Patients with mild to moderate open-angle glaucoma.
- Individuals seeking a safer alternative to trabeculectomy.
- Patients intolerant to medications or needing improved IOP control.
- Those with healthy conjunctiva and no extensive scarring.
- Patients undergoing combined cataract + MIGS surgery.
- Individuals looking for long-term, low-risk IOP management.
Possible Risks & Complications
Although deep sclerectomy is far safer than penetrating surgeries, mild risks include:
- Transient IOP spikes or dips: Common during early healing.
- Micro-perforation of the membrane: Rare and usually manageable.
- Mild inflammation: Easily treated with drops.
- Scleral thinning sensitivity: Minimized through Korean imaging-guided precision.
- Subconjunctival fibrosis: Controlled with anti-scarring agents and implants.
Korean surgeons rely on OCT-guided scleral mapping, AI planning, and biocompatible implants to reduce complications and ensure stable, predictable outcomes.
Surgical Techniques
AI-Assisted Preoperative Planning
Determines ideal scleral flap dimensions, thickness, and outflow characteristics.
Non-Penetrating Scleral Dissection
Microsurgical tools create a deep scleral flap without entering the anterior chamber.
Trabeculo-Descemet’s Membrane Exposure
A thin filtration membrane is revealed, allowing gentle aqueous percolation.
Use of Implants (Optional)
Collagen or hyaluronic implants maintain space and prevent scarring.
Viscodilation & Flow Optimization
Viscoelastic material is used to enhance flow through Schlemm’s canal.
OCT-Guided Thickness Verification
Ensures safe membrane preservation and accurate flap depth.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Comprehensive Evaluation
Includes OCT imaging, visual field testing, IOP assessment, and AI-based flow modeling.
Step 2 – Surgical Planning
Determines flap size, implant use, and membrane exposure strategy.
Step 3 – Scleral Flap Creation
A superficial scleral flap is made, followed by a deeper flap to expose the TDM.
Step 4 – Membrane Exposure & Implant Placement
A controlled filtration zone is created; implants may be placed to prevent collapse.
Step 5 – Postoperative Care
Regular IOP checks and imaging ensure stable filtration and healing.
Treatment Duration: 20–30 minutes per eye
Setting: Outpatient or short-stay center
Recovery & After-Care
After-Care Guidelines
- Use antibiotic and anti-inflammatory drops for 2–4 weeks.
- Avoid intense exercise, eye-rubbing, and water exposure for 1–2 weeks.
- Wear UV-protective sunglasses outdoors.
- Monitor IOP regularly in scheduled follow-up visits.
- Continue medications only if recommended post-surgery.
Recovery Timeline
Days 1–3: Mild discomfort; filtration begins functioning.
Week 1: IOP stabilizes; inflammation decreases significantly.
Weeks 2–4: Further stabilization and improvement of visual comfort.
1–3 Months: Full healing with long-term, predictable IOP control.
