Crystalens studies accommodating lens
Multifocal IOLs incorporate discrete optical elements into the lens to offer both near and distance vision.
This design strategy trades off some of the benefits of seeing through a single zone in order to have a greater range of focus. While many multifocal patients can read without glasses, their distance vision may not be as sharp as it might be with a monofocal IOL.
In fact much of our time is spent looking at things in the intermediate range.
Most people who receive Crystalens implants in both eyes are thrilled with the quality and range of their vision.
The only accommodating lens currently available is Crystalens made by Bausch and Lomb.
A clear focal point for distance is usually chosen leaving intermediate and near vision out of focus and blurred requiring glasses to bring the vision back into a clear focus.
The Crystalens offers the patient the ability to reduce dependance on glasses for near vision tasks.
The latest Crystalens AO is the fourth generation of the Cystalens making it even better.
For nearly two decades, “presbyopia-correcting” intraocular lenses (IOLs) have been available to post-cataract surgery patients, but for a variety of reasons they have garnered only modest interest.
According to , presbyopia-correcting lenses only account for 2.4% of total IOLs implanted globally in 2014.
