Question 1

What is Implantable Contact Lens (ICL)?

Accepted Answer

ICL is a soft, biocompatible lens placed surgically inside the eye, behind the iris and in front of the natural crystalline lens. It corrects vision by focusing light correctly onto the retina without reshaping or removing corneal tissue. Unlike standard contact lenses, it requires no daily removal or maintenance and is a reversible alternative to laser vision correction.

Question 2

How is ICL different from LASIK?

Accepted Answer

LASIK permanently reshapes the cornea using a laser, removing corneal tissue. ICL places a lens inside the eye without touching the cornea. Key differences: ICL is reversible (LASIK is not), ICL suits thin corneas (LASIK requires adequate thickness), ICL corrects higher prescriptions (up to –20D vs ~–10D for LASIK), and ICL causes less dry eye as corneal nerves are not severed.

Question 3

Who is a good candidate for ICL?

Accepted Answer

ICL is suitable for adults aged 21–45 with stable myopia (–3D to –20D), adequate anterior chamber depth (≥2.8mm), healthy endothelial cell count, and no active eye diseases. It is particularly valuable for patients with thin corneas, high prescriptions outside LASIK's range, chronic dry eyes, or those who want a reversible procedure.

Question 4

Will I feel or see the lens inside my eye?

Accepted Answer

No. The ICL is positioned behind the iris and is completely invisible from the outside. Once the eye has healed (typically within 24–48 hours), patients cannot feel the lens at all. The Collamer material is biocompatible and integrates naturally with the eye's environment.

Question 5

What is Collamer material?

Accepted Answer

Collamer is a proprietary biocompatible co-polymer developed by STAAR Surgical that contains collagen — the same protein found naturally in the eye. It is soft, flexible, UV-filtering, and highly compatible with ocular tissue, making it unlikely to cause inflammation or rejection.

Question 6

What is the difference between EVO ICL and older ICL versions?

Accepted Answer

EVO ICL features a central aquaport (KS-AquaPORT) that allows natural aqueous fluid flow, eliminating the need for a pre-operative laser peripheral iridotomy. EVO+ ICL has a larger 6.1mm optic to reduce halos in patients with larger pupils. EVO ICL received FDA approval in 2022.

Question 7

How long does the surgery take?

Accepted Answer

ICL implantation typically takes 20–30 minutes per eye. It is performed as a day-care outpatient procedure under topical anaesthetic eye drops — no injections or general anaesthesia required. Most patients are discharged within a few hours.

Question 8

Is the procedure painful?

Accepted Answer

The procedure is virtually painless. Anaesthetic eye drops numb the eye surface completely. Most patients report only mild pressure during surgery. Some mild discomfort or light sensitivity may occur in the first 24–48 hours as the eye heals, but this resolves quickly.

Question 9

How soon can I return to normal activities?

Accepted Answer

Most patients see well the next day. Light daily activities resume within 24–48 hours. Driving is usually permitted after the first follow-up if vision is adequate. Swimming, contact sports, and eye rubbing should be avoided for 2–4 weeks as directed by your surgeon.

Question 10

What is the recovery timeline?

Accepted Answer

Day 1: Post-op checkup, most patients see well. Week 1: Resume most normal activities. Month 1: Comprehensive follow-up, vision fully stabilised. Full healing typically occurs within 4–6 weeks. Antibiotic and anti-inflammatory eye drops are used for 2–4 weeks post-surgery.

Question 11

What happens on the day of ICL surgery?

Accepted Answer

Dilating and anaesthetic drops are instilled on arrival. The surgeon makes a 2.8–3mm self-sealing incision, inserts the folded ICL using an injector, positions it behind the iris, then confirms vault and pressure. You rest briefly, then are discharged with a protective shield and prescription eye drops.

Question 12

Do I need to stop wearing contact lenses before surgery?

Accepted Answer

Yes. Soft contact lenses should be stopped at least 1 week before surgery (2–3 weeks for rigid/RGP lenses). Contact lenses alter corneal curvature and can affect pre-operative measurements. Your surgeon will advise the exact duration based on the type of lenses you wear.

Question 13

Is ICL surgery safe?

Accepted Answer

ICL has been performed on over 2 million patients globally with a success and satisfaction rate exceeding 99% in clinical studies. It is FDA-approved (EVO+ ICL, 2022) and CE-marked. Like any intraocular procedure, it carries small risks, but these are generally manageable when performed by an experienced ophthalmologist with proper pre-operative screening.

Question 14

What are the main risks of ICL?

Accepted Answer

Common temporary effects: glare, halos, and night vision changes (usually resolve within weeks to months). Less common risks: elevated intraocular pressure, lens sizing issues, and early cataract formation. Rare risks: infection and corneal endothelial cell loss. Regular follow-up allows early detection and management of any complications.

Question 15

Is ICL reversible?

Accepted Answer

Yes — reversibility is one of ICL's most important advantages. The lens can be surgically removed or replaced by an experienced surgeon if vision changes, if the patient develops cataracts, or if any complication arises. This is fundamentally different from LASIK, which permanently reshapes the corneal tissue.

Question 16

How long does the ICL lens last?

Accepted Answer

ICL lenses are designed to last indefinitely. The Collamer and hydrophilic acrylic materials do not degrade over time. Long-term studies at 10+ years show maintained safety and efficacy. Annual eye examinations are recommended to monitor vault, intraocular pressure, and overall ocular health.

Question 17

Can ICL cause blindness?

Accepted Answer

Blindness from ICL surgery is extremely rare. The procedure has a global success rate exceeding 99%. Serious complications are risk-managed through proper screening, sterile technique, and prompt follow-up. The reversible nature of ICL means most issues can be corrected if detected early.

Question 18

Who should not get ICL surgery?

Accepted Answer

ICL is not recommended for: patients under 21, anterior chamber depth <2.8mm, low endothelial cell count, uncontrolled glaucoma, active uveitis, significant cataracts, keratoconus, unstable prescription (changed >0.5D in the past year), or uncontrolled systemic conditions like diabetes. A full pre-operative evaluation determines final eligibility.

Question 19

What does ICL surgery cost in India?

Accepted Answer

ICL surgery in India typically costs ₹50,000–₹80,000 per eye depending on the lens brand: IPCL ≈ ₹50,000, BioTech ≈ ₹55,000, IPCL Premium ≈ ₹75,000, STAAR EVO ICL ≈ ₹80,000. Total bilateral costs range from ₹1,00,000–₹1,60,000 including surgery, anaesthesia, and post-op care. Prices vary by city and hospital.

Question 20

Is ICL covered by insurance in India?

Accepted Answer

Many health insurance policies in India cover ICL surgery as a medically necessary procedure for high myopia. Coverage depends on your specific policy terms. Some policies require pre-authorisation and a waiting period. Cashless treatment is available at many network hospitals through TPA tie-ups. Check your policy documents or ask your hospital's insurance desk for details.

Question 21

Why does ICL cost more than LASIK?

Accepted Answer

ICL costs more because the lens is a custom-manufactured medical implant ordered to your specific eye measurements — unlike the consumables used in LASIK. Surgical complexity is slightly higher, and the custom lens ordering process adds cost. Most patients consider the premium worthwhile given ICL's reversibility, broader correction range, and lower dry eye risk.

Question 22

Is EMI or financing available for ICL surgery?

Accepted Answer

Yes. Many eye hospitals in India offer ICL surgery financing through EMI schemes via healthcare financing partners such as Bajaj Finserv Health EMI or standard credit card EMI programmes. Some hospitals offer their own instalment plans. Ask your chosen hospital about zero-cost or low-interest EMI options when enquiring about the procedure.
