Treatment Overview
The Light Adjustable Lens implantation in Korea is a cutting-edge cataract or lens-exchange procedure that uses a special photosensitive intraocular lens (IOL) whose refractive power can be customised post-implantation via ultraviolet (UV) light treatments.
In Korea, ophthalmologists combine this technology with advanced diagnostics (AI-biometry, wavefront aberrometry), precision micro-incision surgery and premium IOL-selection workflows to deliver highly tailored visual outcomes.
This approach is ideal for patients seeking the ultimate precision in refractive correction and minimal need for glasses after surgery.
Purpose & Benefits
Purpose
- Implant a premium IOL to replace the natural cloudy lens (cataract) or perform refractive lens exchange.
- After healing, adjust the IOL’s power to optimise visual outcome based on the patient’s actual postoperative vision.
- Address residual refractive errors (sphere and cylinder) that arise after standard IOL implantation.
- Provide a customised visual result — e.g., preference for distance, intermediate or near focus — after experiencing early vision.
Benefits
- Post-operative adjustability: Unlike standard IOLs, the power can be changed after surgery to better match real-world vision.
- Reduced refractive surprise: Especially useful for patients with prior refractive surgery, irregular corneas or those with higher expectations.
- Potential for higher satisfaction: By tailoring vision after surgery, the chance of needing glasses or enhancement may be lowered.
- Flexibility: Allows patient + surgeon to “fine tune” the outcome after the IOL is already in the eye.
Ideal Candidates
This procedure in Korea is ideal for:
- Patients undergoing cataract surgery or refractive lens exchange who want premium visual outcomes and are willing to engage in additional follow-up visits.
- Individuals with complex eyes (previous LASIK/PRK, irregular cornea, strong cylinder) where standard predictions may be less reliable.
- Those who desire minimal dependence on glasses and are comfortable with a premium-technology investment.
- Patients who are motivated, able to comply with the post-operative adjustment process (wear UV-protective glasses, attend visits).
- Patients whose lifestyle demands high visual precision (e.g., pilots, precision workers, those with high visual optical demands).
Possible Risks & Complications
While the Light Adjustable Lens is safe and effective, potential risks and considerations include:
- Need for strict compliance with wearing UV-protective glasses until the “lock-in” stage; inadvertent UV exposure may affect lens power.
- Multiple post-operative visits for light treatments (1-3 adjustments + 2 lock-in treatments) are required.
- The lens and process are more expensive compared to standard IOLs.
- Not all patients are suitable: e.g., those on medications that increase UV sensitivity, history of ocular herpes, nystagmus, or heavy UV-exposure professions.
- Risks inherent to any cataract/IOL surgery: infection, inflammation, IOL decentration, posterior capsular opacification, residual refractive error.
- Some learning curve for surgeons and clinics in adjustment workflows.
Techniques & Technology Used
Core Techniques
- AI-guided biometry and wavefront analysis to determine initial IOL power and visual target.
- Standard cataract extraction or refractive lens exchange with micro-incision phacoemulsification.
- Implantation of the Light Adjustable Lens.
- Post-operative adjustment sessions: Using a dedicated Light Delivery Device (LDD) that exposes the lens to controlled UV light to change its curvature/power.
- Lock-in treatment: Once desired vision is achieved, the entire lens is exposed to UV to polymerise remaining macromers and “lock” the power.
Korean clinics integrate these steps with high-end diagnostic equipment and experienced premium IOL surgeons, offering refined workflows for international patients.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Evaluation: Full eye exam including biometry, topography, ocular surface assessment, lifestyle/vision goals consultation; determine if Light Adjustable Lens is appropriate.
Step 2 – Surgical Implantation: Cataract or lens-exchange surgery with insertion of the LAL.
Step 3 – Healing & Initial Vision Check: Wait several weeks for eye to settle (typically around 3-4 weeks) before first light-adjustment.
Step 4 – Adjustment Sessions: 1-3 light treatments spaced days apart; patient trials vision, communicates preferences (distance vs intermediate vs near).
Step 5 – Lock-In Treatments: After final adjustment, 2 treatments to permanently fix lens power.
Step 6 – Post-operative Monitoring & Final Vision Check: Confirm visual outcome, final refraction, lens centration, ocular health.
Treatment Duration: Surgery ~15-30 minutes per eye; adjustment sessions ~< 90 seconds each (plus exam time) over a few weeks.
Setting: Out-patient; multiple visits required for adjustment period.
Recovery & After-Care
After-Care Guidelines
- Use of antibiotic and anti-inflammatory drops as per standard cataract surgery.
- Strict UV-protection: Wear prescribed UV-protective glasses during waking hours until lock-in complete.
- Avoid eye-rubbing, heavy exertion, swimming, contact sports until surgeon permits.
- Maintain ocular surface health (lubricants, treat dry eye) for optimal vision outcome.
- Attend scheduled follow-up visits for refraction and adjustment sessions.
- Lifestyle discussion on vision goals: distance only, blended vision, monovision etc.
Recovery Timeline
- Day 1-3: Initial healing, vision may be somewhat cloudy or fluctuating.
- Week 1-2: Visual improvement; still waiting for stabilisation before adjustments.
- Weeks 3-5 (approx.): First light-adjustment session possible; vision begins to be fine-tuned.
- Weeks 5-8: Final adjustments and lock-in; vision stabilises.
- 3-6 months: Final outcome; patient fully adapted; long-term follow-up ongoing.
Results & Longevity
Expected Results
- Highly accurate refractive outcomes; many patients achieve 20/20 or better unaided vision depending on target and eye health.
- Reduced need for glasses for distance or other targets based on patient preference.
- Greater satisfaction due to ability to fine-tune vision post-implantation.
Longevity
Once the lens is locked-in, the refractive outcome is permanent (analogous to standard IOL). The adjustable feature allows customisation, but after lock-in the lens behaves like a fixed IOL.
Long-term data show stable performance; as the technology is relatively new, patients should continue regular ophthalmic follow-up.
