During cataract surgery the natural lens is removed and it is most often replaced by an artificial lens, called an intraocular lens (IOL). An IOL is a clear, plastic lens that requires no care and becomes a permanent part of your eye. Light is focused clearly by the IOL onto the retina, improving your vision. You will not feel or see the new lens.
Once healing is complete, an eye with an implant lens usually provides adequate vision for the patient to perform most daily tasks without the aid of additional correction. However, glasses are often necessary for distance vision and for reading small print. (Some patients prefer bifocals, which eliminate the need for the repeated removal of their glasses.)
For more information on IOL, please contact the Center for Devices and Radiological Health (CDRH) at the U.S. Food and Drug Administration (FDA). The FDA sponsors clinical studies on medical devices, such as accommodative IOL’s, and regulates their development and marketing.
