Treatment Overview
Light Adjustable Lens Implantation in Korea is one of the most advanced forms of cataract and refractive lens surgery, offering patients the unique ability to fine-tune their vision after surgery using precise, non-invasive UV light adjustments. Unlike traditional intraocular lenses (IOLs) with fixed power, the LAL allows ophthalmologists to modify the lens’ optical properties post-implantation, ensuring highly customized vision correction that perfectly matches each patient’s visual needs.
Korean eye centers are among the first in Asia to integrate AI-guided biometry, femtosecond laser-assisted cataract surgery (FLACS), and digital centration systems with the Light Adjustable Lens technology to deliver unmatched visual precision, adaptability, and satisfaction.
Purpose & Benefits
Purpose
- Replace the natural or cataractous lens with a photosensitive intraocular lens that can be adjusted after surgery to refine vision.
- Provide personalized correction for myopia, hyperopia, presbyopia, and astigmatism.
- Enable patients to experience their vision and fine-tune it to perfection through controlled light treatments.
- Achieve outcomes beyond what static, pre-calculated IOLs can deliver.
Benefits
- Postoperative Customization: Vision is adjusted after healing to achieve optimal results tailored to each patient.
- High Precision: Allows correction of small residual refractive errors after surgery that would otherwise require glasses or laser enhancement.
- Versatile Vision Options: Patients can test and choose their preferred visual setup — distance, near, or blended focus.
- Enhanced Visual Quality: Fine-tuning improves contrast sensitivity and reduces visual distortions.
- Non-Invasive Adjustments: All modifications are performed via targeted UV light sessions, without additional surgery.
- Stable Long-Term Clarity: Once locked in, the final vision correction remains permanent and stable.
Ideal Candidates
Light Adjustable Lens implantation in Korea is ideal for:
- Cataract patients desiring the most precise, customizable visual outcomes.
- Individuals with high expectations for accuracy and spectacle independence.
- Post-refractive surgery patients (LASIK, PRK, RK) whose corneal irregularities make standard IOL calculations less predictable.
- Those with residual astigmatism or complex refractive profiles seeking an adjustable solution.
- Patients who prefer flexibility to “preview and adjust” their vision after surgery for the best results.
Possible Risks & Complications
While extremely safe, a few considerations apply:
- Multiple visits required: Light adjustment sessions occur after healing (typically 2–4 sessions).
- UV Protection: Patients must wear special UV-blocking glasses until vision is finalized to prevent unintended lens adjustments.
- Temporary light sensitivity: Mild photophobia may occur during adjustment period.
- Standard surgical risks: Minor inflammation, dry eye, or residual refractive error prior to adjustment, all easily managed.
Korean ophthalmic surgeons minimize these risks using AI-calibrated treatment plans, high-precision imaging, and strict post-operative protocols.
Techniques & Technology Used in Korea
- AI-Guided Biometry: Uses advanced optical coherence interferometry and ray-tracing software to calculate baseline IOL power.
- Femtosecond Laser-Assisted Cataract Surgery (FLACS): Creates precise capsulotomy and lens segmentation for perfect LAL positioning.
- Digital Centration & Tracking Systems: Ensures accurate lens alignment for post-op adjustments.
- Postoperative Light Treatment Unit: Delivers UV light to the lens in controlled, low-dose sessions to modify its refractive power.
- OCT-Based Monitoring: Confirms corneal stability and lens centration before each adjustment.
- UV Lock-In Process: Once the ideal visual target is achieved, a final “lock-in” exposure stabilizes the lens permanently.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Evaluation:
Comprehensive diagnostics including corneal topography, axial length measurement, and macular OCT. AI simulation helps determine initial lens power and visual goals.
Step 2 – Surgery (Lens Implantation):
Performed via femtosecond laser-assisted or micro-incision phacoemulsification. The Light Adjustable Lens is implanted precisely in the capsular bag.
Step 3 – Healing Period:
A short period (typically 2–3 weeks) allows the eye to stabilize before adjustments. During this time, patients wear UV-blocking glasses.
Step 4 – Light Adjustment Sessions:
Custom UV light treatments reshape the lens’ refractive profile, typically over 2–4 sessions spaced several days apart.
Step 5 – Final Lock-In:
Once the ideal visual outcome is achieved, a final UV treatment locks the lens permanently in its adjusted state.
Treatment Duration: 15–25 minutes per eye (surgery)
Adjustment Sessions: Each lasting ~2–3 minutes
Setting: Outpatient (same-day discharge)
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic and anti-inflammatory eye drops for 2–4 weeks.
- Always wear UV-blocking glasses until final lock-in.
- Avoid heavy exertion, eye rubbing, or direct sunlight during the adjustment phase.
- Attend all scheduled adjustment sessions for optimal precision.
- Follow up at Day 1, Week 1, Week 3, and post-final lock-in to monitor stability.
Recovery Timeline
- Days 1–3: Clearer vision; mild sensitivity possible.
- Weeks 1–3: Vision stabilises, ready for first adjustment.
- Weeks 3–5: Multiple light adjustments fine-tune clarity and sharpness.
- 1–2 Months: Lock-in completed; final visual stability achieved with permanent correction.
