AcrySof^® IQ IOL Designated as a New Technology Intraocular Lens

FORT WORTH, Texas – May 21, 2006 – Alcon, Inc. (NYSE:ACL) announced today that the Centers for Medicare and Medicaid Services (CMS) recognized the AcrySof^® IQ intraocular lens (IOL) as belonging to the New Technology Intraocular Lens (NTIOL) classification of Reduced Spherical Aberration. This NTIOL designation is effective on May 19, 2006 and will increase the Medicare payment to ambulatory surgery centers (ASC) for cataract surgery by $50 when surgery is performed with an AcrySof IQ^® IOL. This NTIOL subset and adjusted payment for the AcrySof^® IQ IOL will remain in effect until February 27, 2011.

The AcrySof^® IQ IOL is an aspheric lens that is designed to reduce spherical aberration and has been shown to improve night driving performance versus a conventional spherical IOL. In order to gain inclusion in the NTIOL category, AcrySof^® IQ demonstrated the same or greater clinical benefit as the lens that established the NTIOL subset.

“We are pleased that CMS has recognized the clinical advantages that patients gain from this advanced lens technology versus conventional IOL implants,” said Kevin Buehler, senior vice president, United States and chief marketing officer. “Studies have shown that by reducing spherical aberration, the AcrySof^® IQ IOL enhances image quality and improves contrast sensitivity.”
