What Is ICL Eye Surgery?

Introduction

ICL (Implantable Collamer Lens) eye surgery is a vision correction procedure designed for individuals with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism. Unlike LASIK, which reshapes the cornea, ICL involves implanting a biocompatible lens inside the eye to enhance vision.

This procedure is a suitable option for those who may not be eligible for LASIK due to thin corneas or severe refractive errors. By understanding what ICL eye surgery is, how it works, and what to expect, patients can make an informed decision about their vision correction options.

What Is ICL?

ICL stands for Implantable Collamer Lens, a soft, flexible lens inserted inside the eye to correct vision. This lens is made from a biocompatible material called Collamer, which is designed to work harmoniously with the eye’s natural structures.

Unlike contact lenses, which sit on the eye’s surface, the ICL is implanted between the iris and the natural lens. This placement allows the ICL to provide a clear vision without altering the cornea’s shape. ICL lenses can remain in the eye indefinitely, but they can also be removed or replaced if necessary.

How ICL Surgery Works

Understanding the ICL surgery process can help reduce concerns and provide clarity about the procedure. Here’s a step-by-step breakdown:

Pre-Surgery Evaluation

Before undergoing ICL surgery, a comprehensive eye examination is conducted to determine eligibility. The evaluation includes:

• Measuring the eye’s shape, size, and thickness.
• Checking for underlying eye conditions such as cataracts or glaucoma.
• Assessing the severity of the refractive error to ensure ICL is a suitable option.
• Discussing expectations, risks, and benefits with an eye specialist.

Anaesthetic Application

On the day of surgery, numbing eye drops are applied to prevent discomfort. In some cases, mild sedation may be provided to help patients relax. Since the procedure does not involve cutting or reshaping the cornea, discomfort is usually minimal.

Lens Implantation

A small incision is made near the cornea, and the folded ICL is inserted through this opening. Once inside, the lens unfolds and is positioned between the iris and the natural lens. This step requires precision to ensure the lens aligns correctly for optimal vision correction.

Recovery and Healing

Since no corneal tissue is removed, recovery from ICL surgery is generally quick. Most patients experience improved vision within a few hours. Full recovery can take a few weeks, during which patients are advised to avoid strenuous activities and follow post-operative care instructions.

Benefits of ICL Surgery

ICL eye surgery offers several advantages compared to other vision correction methods:

Biocompatible Material

The implantable collamer lens is made from a biocompatible material that integrates seamlessly with the eye, reducing the risk of irritation or rejection.

Reversibility

Unlike LASIK, which permanently alters the cornea, ICL surgery is reversible. The lens can be removed or replaced if needed, providing flexibility for future eye treatments.

UV Protection

ICL lenses offer built-in UV protection, which helps shield the eyes from harmful ultraviolet rays. This feature is beneficial for individuals who spend significant time outdoors.

Suitable for Thin Corneas

Patients with thin corneas who are not eligible for LASIK may still qualify for ICL surgery. Since the procedure does not involve corneal reshaping, it is a viable alternative for those with limited corneal thickness.

Types of ICL Lenses

There are different types of ICL lenses available, depending on the patient’s refractive error and eye anatomy.

Spherical ICL

Designed for individuals with myopia, spherical ICL lenses correct nearsightedness without affecting astigmatism.

Toric ICL

Toric ICL lenses are used for patients with both myopia and astigmatism. These lenses have additional cylindrical correction to address irregular corneal curvature.

Multifocal ICL

Some advanced ICL lenses provide multifocal vision correction, reducing dependency on reading glasses for individuals with presbyopia.

Risks and Considerations

As with any medical procedure, ICL surgery carries potential risks and considerations.

Increased Eye Pressure

In some cases, the implanted lens may cause increased intraocular pressure, requiring monitoring and potential treatment.

Cataract Development

While rare, some patients may develop cataracts earlier than expected after ICL implantation. Regular eye exams help detect any changes early.

Infection or Inflammation

Proper post-operative care is essential to prevent infections or inflammation. Patients should follow hygiene guidelines and use prescribed eye drops.

What Is the Cost of ICL Surgery in India?

The Implantable Collamer Lens cost in India varies depending on several factors:

• The type of ICL lens used (spherical, toric, or multifocal).
• The expertise of the ophthalmologist performing the procedure.
• The facility where the surgery is conducted.
• Additional pre- and post-operative care requirements.

On average, ICL surgery in India can range from ₹70,000 to ₹1,00,000 per eye. It is advisable to consult with a trusted eye care provider for an accurate cost estimate.

Conclusion

ICL eye surgery is an effective vision correction method for those seeking an alternative to LASIK or traditional contact lenses. By understanding what ICL eye surgery is, its benefits, and potential risks, individuals can make an informed decision about their vision care. Consulting an ophthalmologist is essential for determining eligibility and exploring available options.
