摘要

Cataract surgery with IOL implantation is performed on millions of patients every year. Despite 25 years of technological innovation, post-surgical refractive errors have remained a problem. Now these errors can be corrected using Calhoun Vision, Inc's light adjustable lens (LAL). The correction is accomplished by implanting a light-sensitive lens, then illuminating it with a spatially varying irradiance profile during a postoperative treatment. This irradiance profile is provided by a Light Delivery Device (LDD), which projects an image of a Texas Instruments DMD onto the implanted lens. Commercial sales of this system began in the summer of 2008 in Europe; US clinical trials began in January 2009.
