Treatment Overview
Laser Trabeculoplasty in Korea is a non-invasive glaucoma treatment that uses targeted laser energy to improve aqueous humor outflow through the trabecular meshwork, thereby lowering intraocular pressure (IOP). It is commonly used for patients with primary open-angle glaucoma and ocular hypertension, offering a safe and effective alternative or supplement to eye drops.
Korean ophthalmology centers are recognized for their advanced AI-calibrated laser systems, high-resolution angle imaging, and precision gonio-targeting techniques, ensuring highly accurate and stable results. The two main types performed in Korea are Selective Laser Trabeculoplasty (SLT) and Argon Laser Trabeculoplasty (ALT).
Purpose & Benefits
Purpose
- Lower IOP by enhancing drainage through the trabecular meshwork.
- Delay or reduce the need for glaucoma medications.
- Prevent progression of optic nerve damage.
- Serve as a primary or secondary treatment option depending on disease severity.
Benefits
- Non-Invasive: No incisions or tissue removal.
- Quick Procedure: Typically completed in under 10 minutes.
- High Safety Profile: Minimal discomfort and low risk of complications.
- Medication Reduction: Many patients decrease reliance on drops.
- Repeatable (SLT): Can be safely repeated if IOP rises again.
- Effective Across Stages: Particularly beneficial for early to moderate glaucoma.
Ideal Candidates
Laser trabeculoplasty in Korea is ideal for:
- Patients with primary open-angle glaucoma (POAG).
- Individuals with ocular hypertension requiring pressure reduction.
- Those who prefer to avoid or reduce medication use.
- Patients intolerant to glaucoma drops.
- Individuals whose IOP remains uncontrolled despite therapy.
- Adults seeking minimally invasive treatment options.
Possible Risks & Complications
Laser trabeculoplasty is extremely safe but may include:
- Mild inflammation for a few days.
- Temporary IOP spike immediately after treatment.
- Light sensitivity or irritation.
- Transient blurred vision.
- Rare peripheral anterior synechiae (ALT).
Korean clinics minimize risks using OCT-based trabecular mapping, AI-guided energy calibration, and post-laser IOP stabilization protocols.
Types of Laser Trabeculoplasty in Korea
Selective Laser Trabeculoplasty (SLT)
Uses low-energy selective photothermolysis to stimulate cellular activity without damaging tissue.
Argon Laser Trabeculoplasty (ALT)
Uses thermal energy to create micro-contraction points that open drainage pathways.
360° Laser Trabeculoplasty
Full-angle treatment for maximum IOP reduction.
Segmental Laser Trabeculoplasty
Targets specific high-resistance drainage areas identified through imaging.
Surgical Techniques
Precision Gonioscopic Targeting
A goniolens allows accurate visualization of the trabecular meshwork.
AI-Calibrated Laser Settings
Ensures optimal energy and pulse duration for safe and effective treatment.
360° or Segmental Treatment Pattern
Customized based on glaucoma severity and drainage resistance.
Controlled Thermal or Selective Photostimulation
SLT uses low-energy pulses; ALT uses thermal micro-spots.
Post-Laser Management
Anti-inflammatory and IOP-lowering drops used as needed.
Treatment Process in Korea
Step 1 – Comprehensive Evaluation
Includes IOP assessment, gonioscopy, OCT imaging, and visual field testing.
Step 2 – Treatment Selection
Determines whether SLT or ALT is most appropriate for each patient.
Step 3 – Laser Trabeculoplasty
Laser energy applied to the trabecular meshwork via a goniolens.
Step 4 – Immediate Care
IOP checked shortly after procedure; medications given if needed.
Step 5 – Follow-Up Monitoring
IOP monitored after days, weeks, and months to ensure long-term success.
Treatment Duration: 5–10 minutes
Setting: Outpatient laser suite
Recovery & After-Care
After-Care Guidelines
- Use anti-inflammatory drops for several days if prescribed.
- Avoid eye rubbing and strenuous activities temporarily.
- Continue glaucoma medications until your doctor advises otherwise.
- Attend all follow-up visits for IOP monitoring.
Recovery Timeline
- Day 1: Mild discomfort or redness possible; early IOP response begins.
- Week 1: Noticeable reduction in IOP for many patients.
- Weeks 2–4: Full effect of SLT or ALT becomes stabilized.
- Months 1–6: Sustained IOP control is maintained.
Results & Longevity
Expected Results
- 20–30% average reduction in IOP.
- Reduced need for glaucoma medications.
- Improved outflow facility and long-term stability.
- Effective slowing of glaucoma progression.
Longevity
- SLT results typically last 1–5 years and can be safely repeated.
- ALT results last 1–3 years but are less repeatable.
- Korean imaging and AI-guided techniques improve durability.
