ICL Implantation (Implantable Collamer Lens)
A reversible refractive surgery that implants a specially designed lens behind the iris to correct high myopia and astigmatism.
ICL (Implantable Collamer Lens) surgery involves implanting an ultra-thin, flexible artificial lens made of Collamer material through a micro-incision into the posterior chamber (between the iris and natural lens). The procedure does not remove corneal tissue, preserving corneal structural integrity, making it especially suitable for high myopia (>-8.00D) or patients with thin corneas unsuitable for laser surgery. The procedure is reversible—the lens can be removed if needed. ICL is widely performed in China's first-tier cities with annual volumes among the highest globally. The latest V4c/V5 generation features a central port design, eliminating the need for laser iridotomy.

Who Is This For
Is ICL Implantation (Implantable Collamer Lens) Right for You?
Good Candidates
- High myopia (-6.00D to -18.00D)
- Thin corneas unsuitable for laser surgery
- Concurrent astigmatism requiring correction
- Those prioritizing high visual quality and reversibility
- Dry eye patients (ICL does not worsen dry eye)
May Not Be Suitable
- Anterior chamber depth <2.8mm
- Insufficient corneal endothelial cell count (<2000/mm²)
- Uncontrolled glaucoma or iritis
- Cataract patients
- Under 18 years old or unstable refraction
Step-by-Step Process
How ICL Implantation (Implantable Collamer Lens) Works
Preoperative preparation
Miotic treatment, topical and peribulbar anesthesia, sterile draping.
Corneal incision
A micro-incision of approximately 3mm is made at the corneal limbus.
Viscoelastic injection
Viscoelastic material injected to maintain anterior chamber space and protect corneal endothelium.
ICL implantation
The folded ICL is injected into the anterior chamber through an injector and unfolds behind the iris.
Lens positioning
The four ICL haptics are placed in the ciliary sulcus, ensuring centration.
Irrigation and closure
Anterior chamber viscoelastic is irrigated, wound seal is confirmed, no sutures required.
Completed in a single procedure. Both eyes are typically done on separate days or the same day, approximately 15-20 minutes per eye.
Cost Information
Cost Estimate for ICL Implantation (Implantable Collamer Lens)
Estimated Price Range
¥4,682.02 – ¥9,510.34
What's Included
Public tier-3A International Medical Department: approximately ¥32,000-42,000 (both eyes, including lens); premium private eye centers: approximately ¥40,000-65,000 (both eyes, including custom V4c Toric astigmatism-correcting lens). The ICL lens is custom-imported from Switzerland and accounts for 60-70% of the total cost.
Before Your Visit
What to Prepare
Required Tests & Examinations
If you already have recent valid test results, bring the reports. If not, these assessments can usually be completed in China before the procedure.
Cycloplegic refraction
Anterior chamber depth measurement (UBM or Pentacam)
Corneal endothelial cell count
Corneal topography
Axial length measurement
Pupil diameter assessment
Documents & Materials to Bring
Required to Bring
Passport and valid visa
Refraction records from past 2 years
Preoperative examination reports
Proof of contact lens discontinuation (soft 1 week, RGP 1 month)
Companion & Support
Accompaniment needed on surgery day; vision may be temporarily blurred.
After Treatment
Recovery & Follow-Up
Rest with eyes closed on surgery day; avoid rubbing eyes
Normal eye use possible from the next day
Avoid water contact with eyes for 1 week
Avoid swimming and strenuous exercise for 1 month
Use prescribed anti-inflammatory and antibiotic eye drops
Regular follow-up to monitor IOP and lens position
Follow-Up Schedule
Follow-up at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year post-surgery. Annual check-ups thereafter.
