ICL Surgery in Kolkata – Safety, Benefits, Risks & Complete Guide (2025)

Hello Reader!

Welcome to the official blog page of Dr. Sagar Bhargava, one of the best ophthalmologists in Kolkata and a leading expert in cataract, refractive, and ICL surgery.

While LASIK remains popular, many patients have thin corneas, high myopia, or dry eyes — making them unsuitable for LASIK or SMILE. For these individuals, ICL (Implantable Collamer Lens) surgery is one of the safest, most effective alternatives.

This guide covers everything you need to know:

• Safety of ICL
• Benefits & risks
• Recovery timeline
• ICL vs LASIK vs SMILE
• Astigmatism correction
• Long-term expectations

What is ICL Surgery?

ICL surgery involves placing a special Collamer lens inside the eye—between the iris and the natural lens. Unlike LASIK, ICL does not cut or reshape the cornea.

ICL is ideal for patients with:

• Myopia up to –20 diopters
• Moderate to high astigmatism
• Thin corneas
• Dry eye tendency
• Unsuitability for LASIK/SMILE

The lens is invisible, painless, and biocompatible. You cannot feel it, and it stays permanently—but can be removed later if required.

Benefits of ICL Surgery

1. Treats very high power

Corrects degrees of myopia and astigmatism beyond LASIK limits.

2. Reversible procedure

ICL can be removed or exchanged if required—an advantage over LASIK.

3. Preserves corneal strength

Because no corneal tissue is removed, long-term corneal stability is excellent.

4. Excellent night vision quality

Fewer higher-order aberrations mean:

• Better night driving
• Sharper contrast
• Reduced glare & halos

5. Rapid visual improvement

Most patients notice clarity within 24 hours.

6. UV protection

The Collamer material naturally blocks UV rays.

Dr. Sagar Bhargava uses advanced diagnostics and custom vault calculations to ensure safe and precise outcomes.

Risks of ICL Surgery

Although highly safe, potential risks include:

• Infection (extremely rare)
• Increased intraocular pressure
• Early cataract development
• Halos or glare
• Endothelial cell changes
• Rotation of toric ICL (correctable)

With proper screening and follow-up, these risks remain minimal.

Is ICL Surgery Safe?

Absolutely.

ICL surgery has one of the highest global satisfaction rates among refractive procedures.

Safety at Dr. Sagar Bhargava’s Clinic Includes:

• Detailed pre-operative eye mapping
• Advanced vault prediction formulas
• Strict sterile surgical protocols
• Long-term postoperative monitoring

How Quickly Will My Vision Improve After ICL?

📅 Within 24 Hours

Significant clarity in most patients.

📅 Days 1–2

Mild irritation, dryness, or slight haziness is normal.

📅 Weeks 1–2

Vision stabilizes further.

📅 Week 4+

Most patients achieve full visual clarity.

📅 1–3 Months

Final stabilization.

Potential Side Effects

• Temporary blurry vision
• Glare or halos
• Mild dryness
• Increased IOP (rare)
• Lens displacement (very rare)

ICL vs LASIK vs SMILE

Can ICL Correct Astigmatism?

Yes.

Toric ICL is specifically designed to correct moderate to high astigmatism (1D–4D).

Benefits:

• Accurate alignment
• Sharp, stable vision
• Superior quality for high cylinders

Long-Term Issues Associated with ICL

Rare but possible:

• Increased eye pressure
• Early cataract changes
• Retinal detachment (mainly in high myopes)
• Endothelial cell reduction
• Rotation of toric ICL

Regular monitoring keeps these risks extremely low.
