Calhoun Vision, Inc. is a privately held company dedicated to enhancing people's quality of vision through advanced technology in materials science and optics. We have a separate website dedicated to patients at www.lalvision.com.

After years of extensive laboratory work, as well as clinical studies of hundreds of patients, Calhoun Vision's Light Adjustable Lens was introduced commercially into countries of the European Union. Today the technology is available to patients in Germany, the UK, France, Italy, Spain, Mexico, the Czech Republic, and Canada, where it is the subject of clinical trials.

In the United States, the Food and Drug Administration (FDA) must first approve the lens before it can be marketed commercially. Calhoun Vision has completed Phases I and II of the required clinical investigation; the third and final phase of study has commenced.
