What is Crystalens, and how is it different from other lens implants?
Crystalens is what is known as a multifocal intraocular lens. Such lenses are designed to focus on near, mid-range, and distant objects. While lens implants have been around for decades, earlier IOLs did not have the range of focus capabilities that today’s implants have. Older lens designs allowed you to focus only in near-range, for example, requiring that you wear glasses for mid-range focus or distant focus.
