Intraocular (in-truh-OCK-yoo-ler) lens implants are small eye lenses made of plastic-like material or silicon. These implants are inserted into the eye after a cataract has been removed. They are usually five millimeters in diameter, small enough to be inserted through a self-sealing, no-stitch incision. The capsular bag of the original lens permanently anchors the new lens implant, treating the new implant as a natural lens. Since the purpose of the lens is to focus incoming light rays properly, you should have much clearer vision after the surgery. Even bifocal lens implants are available to help you see things up close. Before the operation, you’ll be tested to determine the type and power of lens that’s best for you. You probably won’t be able to feel your new lens, and it never needs to be handled, adjusted, or cleaned. If cost is a factor, be aware that Medicare and many insurance plans often cover the costs of cataract surgery and lens replacement.
