Treatment Overview
Ahmed Glaucoma Valve Implantation in Korea is an advanced glaucoma surgery designed to provide long-term intraocular pressure (IOP) control by regulating aqueous drainage through a unidirectional flow valve. Although traditionally categorized as filtration surgery, modern Korean ophthalmology centers utilize micro-incision, tissue-sparing implantation techniques, making the procedure compatible with the goals of Minimally Invasive Glaucoma Surgery (MIGS) when performed with enhanced precision and reduced trauma.
The Ahmed Valve is engineered to prevent early postoperative hypotony through its built-in flow-restriction mechanism. Korean clinics combine this technology with OCT-guided assessment, AI-based IOP prediction, microplate positioning systems, and improved biocompatible implants, offering safer surgical profiles, faster healing, and greater long-term stability.
Purpose & Benefits
Purpose
- Reduce intraocular pressure in moderate to severe glaucoma cases where medications or MIGS alone are insufficient.
- Provide controlled aqueous outflow using a unidirectional pressure-sensitive valve.
- Prevent optic nerve damage and preserve remaining vision.
- Offer a reliable long-term solution for patients at risk of progressive glaucoma.
Benefits
- Immediate IOP Regulation: The valve activates at a preset pressure, minimizing hypotony risk.
- Suitable for Complex Glaucoma: Effective for refractory, secondary, or congenital glaucoma cases.
- Tissue-Sparing Technique: Korean surgeons use micro-incision placement for reduced trauma.
- Long-Term Pressure Stability: Provides sustained IOP reduction for many years.
- Improved Safety Profile: The non-obstructive valve mechanism reduces postoperative fluctuations.
- Works When MIGS Alone Fails: Ideal for severe or advanced patients needing a stronger intervention.
Ideal Candidates
Ahmed Glaucoma Valve Implantation in Korea is ideal for:
- Patients with moderate to severe glaucoma unresponsive to medications or MIGS.
- Individuals with secondary glaucoma, such as neovascular or uveitic glaucoma.
- Patients who have undergone prior unsuccessful glaucoma surgeries.
- Those requiring safer outflow control with reduced risk of hypotony.
- Adults or children with congenital or developmental glaucoma.
- Individuals needing predictable, continuous IOP management.
Possible Risks & Complications
Although AGV implantation is highly reliable, potential risks may include:
- Transient hypotony or pressure spikes: Rare due to valve mechanism.
- Mild inflammation or redness: Controlled with short-term medication.
- Tube exposure or migration: Reduced significantly by Korean micro-suturing techniques.
- Corneal edema: Usually prevented with optimized tube positioning.
- Bleb fibrosis: Can be managed with postoperative modulation therapy.
Korean ophthalmologists utilize OCT-guided tube placement, anti-fibrotic modulation, and AI-calibrated surgical planning to minimize complications and ensure long-term success.
Surgical Techniques
AI-Guided Preoperative Planning
Predicts IOP outcomes, assesses angle structures, and determines valve model and tube placement.
Micro-Incision Valve Implantation
A refined technique using a 2.0–2.4 mm incision to insert the valve with minimal conjunctival disruption.
Precision Tube Placement
The tube is positioned into the anterior chamber, sulcus, or pars plana for ideal flow and corneal protection.
Biocompatible Plate Fixation
The valve plate is anchored securely to maintain stable function without excessive scarring.
OCT-Guided Real-Time Imaging
Verifies depth, angle entry, and tube centration during surgery.
Mitigation of Fibrosis
Korean clinics use anti-scarring protocols to prolong valve success and prevent bleb failure.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Comprehensive Glaucoma Evaluation
Includes OCT imaging, visual field testing, gonioscopy, and AI-based risk assessment.
Step 2 – Surgical Strategy Design
Determines valve type, tube length, implant location, and postoperative target pressure.
Step 3 – Micro-Incision Valve Placement
A valved implant is inserted under the conjunctiva, and the tube is guided into the eye through a micro-access port.
Step 4 – Tube Optimization & Fixation
Surgeons confirm tube position using OCT and secure it with micro-sutures.
Step 5 – Postoperative Monitoring
Ongoing evaluations ensure proper tube function, bleb health, and stable IOP reduction.
Treatment Duration: 20–30 minutes per eye
Setting: Outpatient or short-stay care center
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic and anti-inflammatory drops for 3–4 weeks.
- Avoid rubbing the eye or intense physical activity for at least 2 weeks.
- Sleep with an eye shield for several nights to protect the implant site.
- Maintain clean eyelids and avoid water entering the eye during early recovery.
- Attend all follow-up checks to monitor valve position and pressure stability.
Recovery Timeline
Days 1–3: Initial healing, mild redness or irritation.
Week 1: IOP begins to stabilize; tube well-positioned.
Weeks 2–4: Controlled pressure reduction with reduced inflammation.
1–3 Months: Final stabilization phase with long-term flow control.
Beyond 3 Months: Consistent, predictable IOP maintenance.
