Imagine you make up your mind to get LASIK done. You talk to your friends and family, and they support your decision. Then, you finally head to get a screening, and it turns out that you’re not eligible for LASIK! It will be unbelievably disappointing, right? Well, don’t worry! There’s another equally effective solution to be specs-free. It’s called the Implantable Collamer Lens, commonly known as ICL eye surgery.

What Is the ICL (Implantable Collamer Lens) Procedure?

ICL eye surgery is a vision correction procedure in which an artificial lens is permanently implanted in the eye. It is used to treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. As the name suggests, the ICL is made out of Collamer, which is a type of collagen. It is a biocompatible material that has been used in the treatment of cataracts for many years.

Unlike LASIK and PRK, ICL procedure doesn’t have a minimum requirement for corneal thickness. Thus, you are eligible for the procedure even if your cornea is too thin. ICL operation is also ideal for people with dry eyes. The Implantable Contact Lens supports the existing eye’s lens to refract the light on the retina and produce clear vision. It is a type of phakic intraocular lens which means that it can be implanted in the eye without the need to take out the natural lens.

Why Choose ICL Surgery Over Glasses and Contacts?

Choosing ICL (Implantable Collamer Lens) surgery over glasses and contacts is a personal decision that depends on various factors, medical considerations, individual preferences, and lifestyle. Here are some reasons why someone might opt for ICL eye surgery instead of relying on glasses or contacts:


  1. Permanent Correction: ICL procedure offers a more permanent vision correction solution compared to glasses and contacts. Once the ICL is implanted, it provides consistent vision correction.
  2. Visual Quality: ICLs can provide high-quality vision which means better visual acuity compared to glasses and contacts. 
  3. Active Lifestyle: For individuals with an active lifestyle or those involved in sports and outdoor activities, ICL surgery may be preferable as it does not bring discomfort during those activities.
  4. Peripheral Vision: ICLs provide a natural field of vision, as they are placed inside the eye. This can be an advantage over glasses, which can have frames that obstruct peripheral vision.
  5. No Maintenance: Unlike glasses and contacts, ICLs require minimal maintenance. There is no need to clean or replace it.
  6. No Dry Eyes: Some people experience dry eyes or discomfort with contact lenses. ICL eye surgery eliminates this side effect.

It’s essential to note that while ICL procedure has its advantages, it also involves a surgical procedure and potential risks. It is crucial to consult with an eye specialist to determine if you are a suitable candidate for ICL surgery. 

ICL Procedure: Toric Lens for Astigmatism

There’s another form of the ICL procedure, which is used to treat cases of myopic astigmatism. It is a customized lens designed to take care of the spherical as well as the cylindrical power of the patient’s eye.  Hence, toric ICL can correct myopia and astigmatism at the same time.
