Treatment Overview
The Inverted Flap Technique for Retinal Detachment is an advanced vitreoretinal procedure used to repair macular or complex retinal tears, especially those associated with macular holes, giant retinal tears, or proliferative vitreoretinopathy (PVR). This technique involves creating and inverting a flap of retinal tissue or internal limiting membrane (ILM) over the tear or macular hole to facilitate retinal closure, improve adhesion, and reduce the risk of recurrent detachment.
In Korea, this technique is performed using cutting-edge surgical technology and highly specialized retinal surgeons:
- 25–27G microincision pars plana vitrectomy (PPV) for minimally invasive surgery
- Intraoperative OCT (iOCT) for real-time monitoring of flap positioning and retinal reattachment
- Widefield visualization systems to map retinal tears and detachment
- Endolaser photocoagulation or diathermy for peripheral retinal break sealing
- Silicone oil or gas tamponade to stabilize the retina post-surgery
- AI-assisted surgical planning for flap size, orientation, and placement
This method allows surgeons to promote retinal healing, prevent flap displacement, and optimize visual outcomes, particularly in challenging detachments.
Purpose & Benefits
Purpose
- Repair macular and complex retinal detachments
- Promote closure of macular holes or large retinal tears
- Reduce recurrence of retinal detachment
- Provide structural support to retinal tissue using inverted flap
- Complement adjunctive tamponade procedures (gas or silicone oil)
- Preserve central and peripheral vision
Benefits
- Effective for complex macular detachments and giant tears
- Minimally invasive with microincision vitrectomy
- Improves retinal adhesion and reduces recurrence risk
- Real-time intraoperative OCT ensures accurate flap placement
- Can be combined with endolaser, diathermy, or cryopexy for optimal outcomes
- Supports rapid visual recovery with high anatomical success
- AI-assisted planning enhances precision and safety
Ideal Candidates
The Inverted Flap Technique in Korea is ideal for:
- Patients with macular holes associated with retinal detachment
- Eyes with giant retinal tears or large macular tears
- Detachments complicated by proliferative vitreoretinopathy (PVR)
- Patients requiring pars plana vitrectomy with precise retinal flap management
- Trauma-induced or recurrent retinal detachments
- High myopia patients with macula-involving detachments
- Individuals requiring adjunctive laser, diathermy, or cryopexy
Possible Risks & Complications
While highly effective, this technique carries potential risks:
Minor/Transient Issues
- Temporary blurred or distorted vision
- Mild eye irritation or discomfort
- Floaters due to residual vitreous
Rare/Serious Risks
- Recurrent retinal detachment
- Retinal or choroidal hemorrhage
- Flap displacement or incomplete closure
- Cataract progression (in phakic eyes)
- Endophthalmitis (very rare)
- Tamponade-related complications (e.g., elevated IOP, gas migration)
Korean clinics minimize risks through:
- Intraoperative OCT for real-time flap monitoring
- Microincision vitrectomy for minimal retinal trauma
- Experienced retinal surgeons specializing in complex macular detachments
- AI-assisted preoperative and intraoperative planning
- Careful selection and placement of tamponade agents
- Structured postoperative monitoring and follow-up

Treatment Process in Korea
Step 1 – Preoperative Assessment
- Comprehensive eye exam including visual acuity, IOP, and fundus evaluation
- OCT and widefield imaging to assess macular involvement and retinal tears
- AI-assisted analysis to plan flap size, orientation, and tamponade strategy
Step 2 – Surgical Procedure
- Local or general anesthesia
- 25–27G microincision vitrectomy performed
- Careful removal of vitreous traction and hemorrhage
- Creation and inversion of retinal or ILM flap over tear or macular hole
- Retinal edges sealed with endolaser, diathermy, or cryopexy
- Fluid–air or fluid–gas exchange performed
- Silicone oil or gas tamponade applied to stabilize flap and retina
Step 3 – Postoperative Follow-Up
- Immediate postoperative exam within 24 hours
- Follow-ups at 1 week, 1 month, and 3 months
- OCT and fundus imaging to confirm flap closure and retinal reattachment
Duration: 90–150 minutes
Setting: Advanced retinal surgery operating room
Recovery & After-Care
After-Care Guidelines
- Maintain head positioning as instructed (usually face-down or specific angle)
- Use prescribed antibiotic and anti-inflammatory eye drops
- Avoid heavy lifting, bending, or strenuous activity
- Protect the eye from trauma and contaminants
- Attend all scheduled postoperative follow-ups
Recovery Timeline
- Immediate: Blurred or distorted vision due to tamponade or flap
- 1–2 Weeks: Retina stabilizes; initial visual improvement
- 1–3 Months: Visual recovery continues as flap integrates and retinal adhesion consolidates
- 3–6 Months: Long-term retinal stability and macular closure confirmed
