Descriptive trade name for the STAAR Myopic Visian Implantable Collamer Lens (ICL) indicated for the correction of high refractive error and is intended for placement behind the iris in the posterior chamber of the phakic eye. Also known as a Phakic Intraocular Lens (P-IOL), the design of the ICL is very similar to that of standard intraocular lenses used for cataract surgery. However, the ICL has been designed with forward vault to minimise contact with the central anterior capsule of the crystalline lens. The lens material is a hydrophilic biocompatible polymer known as Collamer and has a history of safe use in approved standard posterior chamber intraocular lenses. Outside the United States the ICL is known as the Implantable Contact Lens. The US Food and Drug Administration rightfully determined this descriptive name would misinform the public of the nature of the P-IOL.
