Implantable Collamer Lens (ICL) Surgery

What is a ICL?

Implantable Collamer Lenses are also known as phakic IOLs (intraocular lenses). These lenses are made from Collamer, a biocompatible material that works in harmony with your body’s natural chemistry.

Unlike traditional contact lenses that go on the surface of your eye, ICLs are placed between your iris and your natural lens to provide long term clear and sharp vision.

This is the best option for young patients who have myopia and astigmatism who are not candidates for laser.

Who Can Benefit from Implantable Collamer Lens (ICL) Surgery?

ICL is an excellent option for patients who:

• Are between the ages of 21 and 45.
• Have moderate to severe nearsightedness (myopia).
• Astigmatism less than 6 diopters.
Are not good candidates for LASIK or PRK due to thin corneas or other corneal issues.

The ICL Procedure:

  1. Consultation and Measurement: A thorough eye examination and precise measurements of the eye are conducted to tailor the ICL to your specific prescription.
  2. Surgery: The procedure is minimally invasive and takes approximately 20-30 minutes. The ICL is inserted through a small incision and placed behind the iris and in front of the natural lens.
  3. Recovery: Patients typically experience a quick visual recovery, with many noticing improved vision almost immediately.

Advantages of Implantable Collamer Lens (ICL)

Clear vision: ICL can provide sharp, clear vision, almost immediately after the surgery.

• Reversibility: Unlike LASIK, the ICL procedure is reversible. The lens can be removed or replaced if necessary.

• An important point to note is that the implantable intraocular lens (IOL), known as ICL, can remain in the eye indefinitely. It is common that starting around the age of 50, the crystalline lens—which is the eye’s natural transparent lens—gradually becomes cloudy and develops cataracts. If this occurs and the patient requires cataract surgery, the ICL lens is removed and a new intraocular lens without cataracts is implanted.

Potential risk of the surgery

• Halos and Glare: Some patients may experience halos around lights or glare, especially at night, following the surgery.

• Infection: As with any surgery, there is a small risk of infection which could potentially be serious.

Cataract Formation: The ICL can cause cataracts to develop sooner in some patients, particularly if the lens inadvertently touches the crystalline lens.

• Increased Intraocular Pressure (IOP): The ICL could lead to an increase in intraocular pressure, which can be a risk factor for glaucoma.

• Endothelial Cell Loss: The cornea’s inner layer may lose cells over time, which could affect corneal health.
