Crystalens

 Accommodating Monofocal IOLs are used in situations where both good distance and good near vision are desired without the use of spectacles. These IOLs have a single focal piont, however, the focal point can shift position in space so that objects at distance are clear when the eye focuses on them, but when the eye looks at a near object the IOL will shift its focal point to bring the near object into focus. Accommodating Monofocal IOLs achieve this by physically moving inside the eye in response to the focusing action of the muscles of the eye. The only FDA approved IOL of this type is called the Crystalens. Patients implanted with the Crystalens IOL generally enjoy near vision without glasses that is much better than those implanted iwth Fixed Focus monofocal IOLs. Vision at the intermediate (computer screen) distance is super with the Crystalens, making this an excellend IOL for those who spend a great deal of time on a computer.
