Treatment Overview
Laser Peripheral Iridoplasty (LPIr) in Korea is a highly refined Minimally Invasive Glaucoma Surgery (MIGS) technique designed to widen the anterior chamber angle by applying targeted laser spots to the peripheral iris. These laser applications contract the iris tissue, pulling it away from the trabecular meshwork and improving aqueous humor outflow.
Often used for narrow-angle glaucoma, plateau iris syndrome, and angle-closure risk, iridoplasty is a safe, quick, and highly effective way to open the angle when laser iridotomy alone is insufficient. Korean ophthalmology centers enhance this procedure using infrared-guided laser targeting, AI-based angle analysis, high-resolution anterior segment OCT, and precision micro-pulse delivery systems to ensure minimal tissue damage, rapid angle widening, and strong pressure control.
Iridoplasty may be performed as a standalone MIGS treatment or combined with other angle-opening procedures such as Goniosynechialysis (GSL), cataract surgery, or canaloplasty.
Purpose & Benefits
Purpose
- Widen the drainage angle by contracting peripheral iris tissue.
- Prevent or treat angle-closure glaucoma and plateau iris configuration.
- Reduce intraocular pressure by improving access to the trabecular meshwork.
- Complement laser iridotomy or other MIGS procedures when the angle remains narrow.
Benefits
- Non-Incisional MIGS: No cuts, no implants, minimal trauma.
- Immediate Angle Opening: Quickly pulls iris tissue away from the drainage system.
- Highly Effective for Narrow Angles: Ideal for plateau iris and persistent angle closure.
- Quick Procedure: Usually completed within minutes.
- Very Low Complication Rate: Minimal inflammation or discomfort.
- Prevents Acute Angle Closure: Decreases long-term risk of emergencies.
- Enhances Success of Other MIGS: Creates better access for trabecular and canal-based MIGS.
Ideal Candidates
Laser Peripheral Iridoplasty in Korea is ideal for:
- Patients with narrow angles or plateau iris configuration.
- Individuals with angle-closure glaucoma or high risk of closure.
- Patients whose angles remain narrow despite laser iridotomy.
- Individuals with poor access to the trabecular meshwork.
- Those preparing for further MIGS procedures (e.g., KDB, canaloplasty, ELT).
- Patients desiring a safe, fast, and minimally invasive angle-widening treatment.
Possible Risks & Complications
The procedure has an excellent safety profile. Mild, temporary effects may include:
- Mild inflammation
- Transient discomfort or light sensitivity
- Slight redness
- Temporary IOP rise (rare and easily managed)
- Peripheral iris pigment release (usually harmless)
Korean surgeons minimize risks through:
- AI-based energy calibration
- OCT-guided angle visualization
- Ultra-precise laser targeting
- Postoperative anti-inflammatory regimens
Surgical Techniques
AI-Based Angle Configuration Analysis
Determines the degree of angle narrowing and optimal laser locations.
Infrared or Argon Laser Application
Laser spots contract the iris stroma, pulling it backward.
Circular Treatment Pattern
A uniform ring of laser burns widens the entire angle circumference.
Anterior Segment OCT Verification
Ensures successful separation of iris tissue from the trabecular meshwork.
Combination Strategy (Optional)
Can be used before GSL, cataract surgery, canaloplasty, or other MIGS.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Angle Imaging & Evaluation
Includes gonioscopy, anterior segment OCT, IOP measurement, and plateau iris assessment.
Step 2 – Laser Planning
AI systems determine laser power, spot size, spacing, and treatment zones.
Step 3 – Laser Peripheral Iridoplasty
Laser is applied to the peripheral iris to contract and reposition tissue.
Step 4 – Postoperative Evaluation
Angle opening and IOP are checked shortly after the procedure.
Step 5 – Follow-Up Monitoring
Follow-up visits ensure angle stability and proper healing.
Treatment Duration: 3–5 minutes
Setting: Outpatient, same-day
Recovery & After-Care
After-Care Guidelines
- Use anti-inflammatory drops for several days.
- Avoid rubbing the eye for 24–48 hours.
- Wear sunglasses outdoors to reduce light sensitivity.
- Monitor IOP as instructed by your surgeon.
- Continue glaucoma medications unless told to taper.
Recovery Timeline
Day 1: Mild irritation possible; angle already widened.
Days 2–4: Vision stabilizes; inflammation subsides.
Week 1: Clear improvement in angle structure.
1 Month: Stable angle configuration with long-term benefit.
Results & Longevity
Expected Results
- Immediate widening of the drainage angle.
- Improved access to the trabecular meshwork.
- Reduced risk of angle-closure episodes.
- Lower IOP through better natural drainage.
