Things to Know Before, During, and After Phakic ICL Surgery

Preparing a sterile Phakic ICL lens before implantation – ensuring safety and optimal visual results
Phakic ICL (Implantable Collamer® Lens) surgery is a modern solution for correcting myopia and astigmatism, especially suitable for patients who cannot undergo LASIK or SMILE due to thin corneas, high myopia, or dry eyes. To achieve optimal results, you need thorough preparation before surgery, understand the procedure on the surgery day, and follow post-operative care instructions.
Before Phakic ICL Surgery
1/ Comprehensive Eye Examination
Your doctor will perform detailed assessments:
- Refraction test to measure myopia and astigmatism
- Measure anterior chamber depth (≥ 3.0 mm)
- Corneal topography to assess curvature and thickness
- Check endothelial cell density
- General eye examination to rule out any ocular diseases
Ideal Candidate Criteria:
| Criteria | Requirement |
|---|---|
| Myopia | -3.0D to -20.0D |
| Astigmatism | 1.0D – 4.0D |
| Age | 21 – 45 |
| Stable Refraction | ≥ 1 year |
| Eye Health | No severe eye diseases |
2/ Health and Lifestyle Preparation
- Stop wearing soft contact lenses at least 1 week before surgery, hard lenses 2 weeks before
- No eye makeup or eye creams on surgery day
- Inform your doctor if you are taking any systemic or topical medications
On the Day of Phakic ICL Surgery

Applying anesthetic and antiseptic eye drops before Phakic ICL implantation
1/ Surgical Procedure
- Apply pupil-dilating and anesthetic eye drops
- Create a small incision at the corneal edge
- Insert and unfold the Phakic ICL lens between the iris and the natural lens
- Adjust and complete – You will not feel or see the lens after placement
Time: 20–30 minutes for both eyes
Painless – No corneal damage – Fast recovery
2/ Surgery Day Precautions
- No eye makeup or cosmetics to prevent infection
- Avoid strong-scented perfumes, hairspray, or creams as they may affect the sterile environment
- Eat a light meal before surgery – avoid greasy or hard-to-digest food
- Wear comfortable clothing, preferably with buttons or zippers to avoid contact with the eyes after surgery
- Do not drive to the hospital – arrange for someone to accompany you, as vision will be unstable right after surgery
- Bring sunglasses or protective glasses to wear immediately after leaving the operating room
- Follow the surgeon’s instructions at every step to ensure accuracy and safety
3/ Immediate Post-Surgery Sensations
- Mild foreign body sensation, watery eyes
- Vision improves almost immediately and continues to sharpen over 24–48 hours
After Phakic ICL Surgery
1/ Post-Operative Eye Care
Regular follow-up visits after surgery help doctors monitor the stability of the Phakic ICL lens and vision, ensuring proper healing progress.
Medication Regimen
- Antibiotic eye drops: Prevent infection (4–6 times/day during the first week)
- Anti-inflammatory drops: Reduce swelling and redness (2–4 weeks)
- Lubricating drops: Keep eyes moist, reduce discomfort

Tip: Wash your hands before instilling drops and avoid touching the dropper tip to your eye.
Eye Hygiene & Protection
