The Visian ICL is a phakic intraocular lens (IOL) used during refractive surgery for correcting myopia. Unlike IOLs that are used during cataract surgery, the Visian ICL does not replace the eye’s natural lens. Instead, the ICL is placed between the iris and the natural lens. Because the phakic IOL does not replace the lens, but supplements it like a prescription contact lens, it is sometimes referred to as an implantable contact lens.
Now, patients who are seeking the latest approved procedures for vision correction or who want to avoid the permanence of laser vision correction have another choice for correction of nearsightedness. If a patient decides to get laser surgery later, or opts for a still undiscovered procedure at some point in the future, the ICL may be removed.
What is Visian ICL?
What Makes the Visian ICL Different?
Although the Visian ICL is often informally defined as an ” implantable contact lens,” in the United States, the “ICL” in the Visian ICL stands for “implantable Collamer lens.” This designation acknowledges the unique material that comprises the lens.
Unique Lens Composition
Unlike other phakic IOLs the Visian ICL is made from Collamer, a unique, organic lens material, designed especially for the Visian lens. This proprietary lens material has greater biocompatibility than acrylic and silicone lenses. Collamer does not cause a reaction inside the eye and contains an ultraviolet filter that provides protection to the eye.
Safe, Proven Procedure
The safety and effectiveness of the Visian ICL implantation procedure has been proven with over 55,000 implants worldwide as well as recent U.S. FDA approval. Unlike corneal refractive surgery, the Visian ICL does not permanently alter the structure of the eye. Instead, the phakic IOL is placed in the eye’s posterior chamber, where it works with the natural lens to correct vision.
Unlike other phakic IOLs, the Visian ICL is foldable. This feature allows physicians to implant the lens using a smaller incision. The small incision procedure is a technique that is familiar to eye surgeons. The Visian ICL requires a 2.8mm to 3.0mm incision as opposed to the 6.0mm incision required by other FDA-approved phakic IOLs. This smaller incision is seen as less invasive, does not require sutures, and is astigmatically neutral.
Removable, if Necessary
The Visian ICL is meant to stay in the eye indefinitely. However, if overcorrection or undercorrection occurs, a complication develops, or a patient’s vision changes, the Visian ICL can be removed or exchanged by a trained ophthalmic surgeon.
