Treatment Overview
Nanopulse Laser Trabeculoplasty (NLT) in Korea is an advanced, non-invasive glaucoma laser treatment that uses ultra-short, low-energy nanosecond pulses to stimulate the trabecular meshwork without causing thermal or structural damage. Unlike argon or selective laser trabeculoplasty, NLT relies on mechanical photostimulation, allowing for cellular rejuvenation and improved aqueous humor outflow with minimal inflammation.
Korea is at the forefront of next-generation trabeculoplasty technology, using AI-guided energy modulation, OCT-assisted targeting, and microsecond-level thermal control to ensure accurate, safe, and long-lasting IOP reduction.
Purpose & Benefits
Purpose
- Improve aqueous humor drainage by stimulating trabecular meshwork cells.
- Lower intraocular pressure (IOP) in patients with open-angle glaucoma.
- Provide a gentler alternative to SLT and ALT.
- Delay the need for medications or surgical intervention.
- Enhance physiological trabecular function without tissue disruption.
Benefits
- Non-Thermal Laser: Eliminates risk of burns or thermal damage.
- High Safety Profile: Minimal inflammation and rapid recovery.
- Repeatable: Tissue integrity preserved for multiple treatment sessions.
- Effective for Early and Moderate Glaucoma: Excellent first-line option.
- Fast Procedure: Usually completed within minutes.
- Little to No Discomfort: Gentle, low-impact laser delivery.
Ideal Candidates
Nanopulse Laser Trabeculoplasty in Korea is ideal for:
- Patients with mild to moderate primary open-angle glaucoma (POAG).
- Individuals with ocular hypertension needing non-invasive IOP control.
- Patients intolerant to or seeking alternatives to glaucoma medications.
- Those who did not fully respond to SLT or ALT.
- Individuals preferring low-risk, repeatable options before surgery.
- Younger patients who need long-term safety without structural damage.
Possible Risks & Complications
NLT is exceptionally safe, but mild, temporary effects may include:
- Trace inflammation
- Mild redness
- Subtle IOP fluctuation
- Temporary blurred vision
- Minor light sensitivity
Korean specialists minimize risks using high-resolution angle imaging, precise laser calibration, and post-laser anti-inflammatory protocols when necessary.
Types of Nanopulse Trabeculoplasty in Korea
Standard Nanopulse Trabeculoplasty (NLT)
Full 360° or segmental trabecular stimulation with nanosecond pulses.
Imaging-Guided NLT
Uses OCT or UBM to target areas of greatest outflow resistance.
Hybrid NLT + SLT
Combines non-thermal stimulation with selective laser effects for enhanced IOP control.
Repeat-Session NLT
Multiple treatments spaced over months for ongoing pressure control.
Surgical Techniques
Goniolens-Assisted Angle Visualization
Ensures clear visualization of trabecular meshwork during treatment.
Nanosecond Pulse Delivery
Laser emits ultra-short pulses to stimulate cellular repair without heating tissue.
AI-Calibrated Energy Adjustment
Matches pulse strength to trabecular resistance patterns.
Segmental or 360° Application
Depends on patient anatomy and glaucoma severity.
Post-Laser Optimization
Anti-inflammatory drops used only if needed.
Treatment Process in Korea
Step 1 – Comprehensive Glaucoma Evaluation
Includes IOP testing, gonioscopy, OCT imaging, and visual field analysis.
Step 2 – Personalized Treatment Planning
Determines pulse count, treatment arc, and energy settings.
Step 3 – Nanopulse Laser Trabeculoplasty
Laser applied to trabecular meshwork via goniolens with high precision.
Step 4 – Immediate Post-Treatment Care
Patient monitored briefly; drops given if necessary.
Step 5 – Follow-Up Monitoring
Regular IOP checks to confirm long-term effectiveness.
Treatment Duration: 5–8 minutes
Setting: Outpatient laser suite
Recovery & After-Care
After-Care Guidelines
- Use lubricating or anti-inflammatory drops if prescribed.
- Avoid rubbing the eyes for 24 hours.
- Resume daily activities almost immediately.
- Continue glaucoma medications unless otherwise directed.
- Attend follow-up appointments for IOP surveillance.
Recovery Timeline
- Day 1: Slight redness or irritation possible.
- Week 1: IOP reduction typically begins.
- Weeks 2–4: Full IOP-lowering effect becomes apparent.
- Months 1–6: Sustained reduction with stable results.
Results & Longevity
Expected Results
- 20–30% reduction in intraocular pressure.
