Treatment Overview
Intraoperative Bleb Modulation Trabeculectomy in Korea is an advanced form of trabeculectomy that focuses on sculpting, shaping, and optimizing the filtration bleb during surgery rather than relying solely on postoperative interventions. Korean surgeons use high-resolution imaging, controlled tissue dissection, and targeted anti-scarring therapy to design a diffuse, stable, and long-lasting bleb while the eye is still under the microscope.
This technique significantly improves long-term filtration outcomes, reduces the risk of bleb failure, and minimizes postoperative complications. Korean glaucoma centers enhance this method using OCT-guided bleb visualization, AI-assisted flow prediction, and customized MMC micro-dosing, allowing precise control over outflow dynamics from the moment the bleb is created.
Purpose & Benefits
Purpose
- Create an ideal bleb form during surgery for maximum long-term filtration success.
- Reduce the risk of postoperative bleb fibrosis, scarring, and flattening.
- Achieve more predictable and stable intraocular pressure (IOP) reduction.
- Improve outcomes in patients at high risk for trabeculectomy failure.
- Minimize the need for postoperative bleb revisions or needling.
Benefits
- Immediate Bleb Quality Optimization: Surgeons shape the bleb intraoperatively for ideal height and diffusion.
- Reduced Postoperative Complications: Less risk of bleb leaks, flat blebs, or overfiltration.
- Long-Term Stability: Produces stable, diffuse blebs with excellent durability.
- Better Flow Control: Enhanced titration of flap resistance and aqueous flow.
- Improved Success in High-Risk Eyes: Especially beneficial for young patients or secondary glaucoma.
- Fewer Postoperative Adjustments: Less need for needling, suturing, or anti-scarring injections after surgery.
Ideal Candidates
Intraoperative Bleb Modulation Trabeculectomy in Korea is ideal for:
- Patients with moderate to severe glaucoma requiring long-term filtration control.
- Individuals with aggressive wound healing or high scarring risk, such as younger patients or those with uveitic or secondary glaucoma.
- Patients with previous failed trabeculectomy due to bleb fibrosis or collapse.
- Eyes with thin or vascular conjunctiva that require careful bleb shaping.
- Individuals seeking higher success rates and fewer postoperative interventions.
Possible Risks & Complications
Although this technique reduces many risks, possible complications include:
- Mild postoperative inflammation
- Temporary IOP fluctuation
- Small hyphema
- Bleb micro-leaks (rare)
- Scar tissue formation over time
- Conjunctival edema
Korean surgeons minimize risks through precise flap titration, customized MMC placement, and intraoperative OCT visualization.
Types of Intraoperative Bleb Modulation Techniques in Korea
Diffuse Bleb Sculpting
Creates a wide, evenly distributed bleb to prevent localized overfiltration.

Flap Resistance Titration
Adjusts flap sutures and tension during surgery to fine-tune outflow.
OCT-Guided Bleb Visualization
Real-time imaging allows surgeons to sculpt the bleb with micrometer precision.
Hybrid Bleb Modulation + Implant Support
Gel or collagen implants support bleb space and prevent collapse.

OCT imaging evaluates bleb structure, stability, and filtration performance.
Treatment Duration: 30–50 minutes
Setting: Hospital or surgical center
Recovery & After-Care
After-Care Guidelines
- Use prescribed eye drops consistently.
- Avoid rubbing the eye and strenuous activities.
- Protect the eye during sleep for the first week.
- Avoid contaminated environments and water exposure.
- Attend follow-up visits for IOP checks and bleb evaluation.
Recovery Timeline
- Days 1–3: Mild discomfort; early bleb stabilization.
- Week 1: Bleb shape becomes more defined; IOP decreases significantly.
- Weeks 2–4: Bleb stabilizes with uniform distribution.
- Months 1–3: Long-term filtration structure fully established.
