As we age, changes occur in our vision that may lead to a number of conditions, such as cataracts and presbyopia.
A cataract is an opaque or cloudy area that forms within the eye's lens, making vision difficult. Cataracts occur with aging or trauma. The treatment for cataracts is to remove the lens and implant an artificial lens, called an intraocular lens (IOL).
