Implantable Contact Lens (ICL)

The Implantable Collamer Lens (ICL) is also known as a phakic IOL. “Phakic” means that the natural lens of the eye has not yet been removed (e.g. by cataract surgery); “IOL” stands for intraocular lens (i.e. a lens inside the eye).

The ICL is considered an alternative to such procedures as LASIK and PRK or Refractive Lens Exchange. The best candidates for the ICL are between the ages of 21 and 50, with moderate to severe nearsightedness.

The ICL is a small, injectable lens made of a material called collamer. This is a collagen compound that is very biocompatible (doesn’t cause a reaction inside the eye) and is stable. It also contains an ultraviolet light filter.

The ICL is inserted through a tiny, 3-mm incision that does not usually require sutures. The procedure is performed on an outpatient basis, which means that the patient has surgery and goes home the same day. A light, topical or local anesthetic is administered, and there is very little discomfort or pain associated with the procedure.

The ICL provides predictable outcomes and excellent quality of vision. If there are major changes in one’s vision, the ICL may be able to be removed or replaced. It is designed to remain in place within the eye without maintenance. Because the lens is positioned behind the iris, neither you nor an observer will be able to see it.
