Treatment Overview
Nanex Crystal IOL implantation in Korea refers to the use of a premium-grade hydrophobic acrylic intraocular lens from the Nanex brand (by HOYA Surgical Optics) that features advanced optical and material technology for high-quality vision. The lens is designed for micro-incision implantation and premium visual outcomes, often used in conjunction with premium surgical techniques and premium IOL workflows in top-Korea eye centres.
Purpose & Benefits
Purpose
- Replace the cataract-clouded natural lens with a premium Nanex Crystal hydrophobic acrylic IOL designed for superior clarity.
- Correct refractive errors (myopia, hyperopia) and potentially mild astigmatism depending on version.
- Provide enhanced vision quality, contrast sensitivity, and long-term durability compared to standard monofocal lenses.
- Leverage micro-incision surgery techniques to reduce surgical trauma and accelerate recovery.
Benefits
- High optical clarity thanks to hydrophobic acrylic material with active-surface treatment to resist posterior capsular opacification (PCO).
- Micro-incision capability: The Nanex multiSert+ injector system allows incision sizes as low as ~1.8 mm, reducing wound stretch and surgically induced astigmatism.
- Aspheric design and sharp optic edge: Improves image quality, reduces aberrations, and enhances contrast.
- Excellent material stability: Over 10 million units implanted worldwide, long history of performance.
- Enhanced surgical workflow: Preloaded injector design (multiSert+ system) for smooth insertion and reduced surgical variability.
Ideal Candidates
Nanex Crystal IOL implantation in Korea is suitable for:
- Patients with cataracts who wish to invest in premium lens technology and expect excellent visual clarity.
- Individuals with healthy ocular anatomy (clear cornea, stable retina, adequate tear film) seeking high-quality vision.
- Those who prefer excellent distance (and possibly intermediate) vision with minimal compromise, and perhaps are less focused on multifocal zones (if this is more of a premium monofocal design).
- Candidates for micro-incision cataract surgery, who want faster healing, less induced astigmatism, and premium outcome.
Possible Risks & Complications
Although the procedure is very safe when performed by experienced surgeons, minor side-effects or risks include:
- Residual refractive error: Even premium lenses may require glasses for very fine tasks or minor correction.
- Posterior capsular opacification (PCO): Although the Nanex lens has design features to reduce PCO, it still may occur and can be treated with a YAG laser.
- Standard cataract surgery risks: infection, inflammation, dry eye, temporary vision fluctuations.
- Near vision limitation: If this lens is more monofocal-premium rather than multifocal, the near reading might still require glasses or magnification.
- Expectations management: Premium lens does not guarantee complete glasses-freedom in all tasks, so counselling is essential.
Surgical Techniques
- AI-Guided Biometry: Precision measurement of corneal curvature, axial length, anterior chamber depth, and simulation of optimal lens power.
- Femtosecond Laser-Assisted Cataract Surgery (FLACS): Many Korean premium centres use femtosecond laser for capsulotomy, lens fragmentation, and corneal incisions to enhance accuracy.
- Micro-Incision Phacoemulsification: Using small (< 2.0 mm) incisions and advanced phaco systems to remove cataract with minimal tissue disturbance. The Nanex lens supports these small incisions via its multiSert+ injector allowing incisions as low as 1.8 mm.
- Preloaded Injector System (multiSert+): The Nanex IOL is delivered via the multiSert+ preloaded system, reducing variability, handling time, and ensuring smooth delivery into the capsular bag.
- Digital Centration & Alignment: Ensuring the lens is well-centred within the capsular bag and optical axis, enhancing the premium optical effect.
- Intraoperative Verification: Some centres use intraoperative aberrometry or optical imaging to confirm lens alignment and refractive target, to maximise premium results.
Treatment Process in Korea
Step-by-Step Workflow
Step 1 – Preoperative Assessment:
Full diagnostics including visual acuity testing, corneal topography/tomography, axial length measurement, macular OCT, tear-film evaluation, and lifestyle visual goals discussion.
Step 2 – Surgical Planning:
Select Nanex Crystal IOL model, calculate lens power and mark surgical plan (incision site, astigmatism correction if applicable), and schedule premium micro-incision procedure.
Step 3 – Cataract Extraction & Lens Removal:
Performed by micro-incision phacoemulsification (<2.0 mm) or femtosecond laser-assisted technique. The cataract is fragmented and removed with minimal ultrasound energy and minimal corneal disruption.
Step 4 – IOL Implantation:
The Nanex Crystal IOL is inserted via the multiSert+ preloaded injector through a ~1.8–2.0 mm incision, centred within the capsular bag, ensuring optimal placement for premium optics.
Step 5 – Postoperative Monitoring:
Follow-up visits to track visual acuity, lens stability/centration, refractive outcome, check for any posterior capsular changes, and ensure healing and adaptation.
Treatment Duration: ~15-25 minutes per eye in a premium Korean centre
Setting: Outpatient, same-day discharge in most cases
Recovery & After-Care
After-Care Guidelines
- Use prescribed antibiotic and anti-inflammatory eye drops for typically 2–4 weeks (as per surgeon’s protocol).
- Avoid rubbing eyes, swimming, heavy exercise, or dusty/windy environments for about one week.
- Wear UV-protective sunglasses while outdoors.
- Use lubricating drops for any dryness or mild irritation.
- Attend follow-up visits at Day 1, Week 1, and Month 1 (and further as per premium clinic protocol) to ensure visual clarity, lens centration and healing.
Recovery Timeline
- Days 1-3: Vision usually becomes noticeably clearer, with minimal discomfort.
- Week 1: Distance vision stabilises, contrast improves, incision healing advances.
- Weeks 2-4: Visual quality improves further; if intermediate tasks are involved, the patient begins full visual function.
- 1–3 Months: Final visual outcome achieved; adaptation complete; long-term clarity and stability expected.
Results & Longevity
Expected Results
- Excellent high-definition distance vision and enhanced clarity/contrast compared to standard monofocal IOLs.
- Improved surgical outcomes owing to micro-incision technique and premium IOL material/design.
- Reduced chance of posterior capsular opacification (PCO) thanks to Nanex’s surface treatment technology.
- High satisfaction in patients who selected premium optics and micro-incision surgery workflows.
Longevity
- The Nanex Crystal IOL is a permanent implant, designed to maintain optical clarity and material stability for decades.
- Hydrophobic acrylic material with proven track record (10+ million implants) demonstrates long-term biocompatibility and resistance to glistening.
- Provided the ocular health remains good (cornea, retina, capsule), visual outcomes and optical performance remain stable long term.
