Implantable Contact Lens Types

Named by Time Magazine as one of the "coolest inventions of 2004," the implantable contact lens (ICL) is an alternative to the LASIK procedure for correcting myopia (nearsightedness). Also referred to as a phakic intraocular lens, an ICL is implanted during eye surgery. For more information on implantable contact lens types and options, read the sections below.

Implantable Contact Lens Types

The main difference between implantable contact lenses is the types of material used to make each ICL. The two main components used in ICL construction are acrylic and Collamer®.

Acrylic ICL

The Verisyse™ implantable contact lens was the first phakic implantable contact lens approved by the FDA. An acrylic ICL, the Verisyse™ lens is made of polymethylmethacrylate (PMMA), the material used in many intraocular lens implants. PMMA has been used in the eyes for over 50 years and proven biocompatible.

The Verisyse™ ICL, also called the Verisyse™ phakic ICL, is placed on top of the iris, just behind the cornea. In this location it is invisible to others and works with the eye’s natural lens to correct vision for those with moderate to extreme myopia (nearsightedness). The Verisyse™ ICL is placed in the eye through an incision in the cornea. This small incision is closed with sutures that dissolve over time. Improved vision is typically experienced the day following ICL surgery, however, your doctor can provide more detailed information on implantable contact lens results based on your individual vision correction needs.

Collamer® ICL

The STAAR® Visian ICL™ is made from a unique combination of copolymer and collagen called Collamer®. This Collamer® implantable contact lens transmits light, reduces reflections and glare, and the collagen makes it extremely biocompatible.

Unlike the PMMA implantable contact lens, the Visian ICL™ is foldable, requiring a very small incision during ICL eye surgery. The folded lens is inserted through the incision and unfolds in the eye between the iris and the eye’s natural lens where it aids in focusing ability. Because the incision is self-healing and does not require sutures, recovery time is extremely short. The Visian ICL™ works with the eye’s natural lens to improve vision for those with moderate to severe nearsightedness and is completely invisible to others.

Speak to a Doctor in Your Area for More Information

Gaining information on the implantable contact lens (ICL) is the first step in your journey to better vision. The next step involves an eye exam from a qualified ophthalmologist. Find an eye doctor in your area and schedule a consultation to find out if ICL eye surgery is the right choice for you.
