Clear lens exchange (also known as the clear lens replacement) is a procedure analogous to cataract surgery. Clear lens exchange has a few factors in common with modern cataract surgery, such as the following:
The only difference between CLR and cataract extraction is that during cataract surgery, the cloudy lens is replaced, whereas in CLR the lens is replaced before it has a chance to turn into a cataract. With the use of the latest generation of presbyopia correcting lenses, patients are able to achieve vision freedom at all distances, far and near.
Modern lens replacement surgery provides the ophthalmologist with a great arsenal of lens implants that allows for restoration of multifocality. We are born with an intrinsic ability to change focus from far to near. As we age, the mechanism responsible for this process loses its effectiveness. This loss of accommodating ability is termed presbyopia, and eventually it progresses to the point where the use of bifocal or progressive lenses is necessary. Lens replacement procedures provide an excellent opportunity to regain the ability to focus at distance and near without the aid of glasses or contacts.
