Presbyopia Lens Implants (Crystalens, ReSTOR, ReZoom)
While monovision is a good option for many lens implant patients, more elaborate lens designs have made it possible for us to correct patients’ eyes so that both eyes can see far and near without glasses or contact lenses.
Accommodating Lens Implants (Crystalens)
Accommodating lenses are single focus implants that attempt to change their focus when a patient makes an effort to view objects at varying distances. The concept is to reproduce the natural mechanism of accommodation that begins to deteriorate in all of us around the age of 40. The Crystalens is the prototype accommodating lens implant, and the only one that has been FDA approved. The revolutionary design element of the Crystalens is "hinges" which allow the lens to move, or accommodate, to seamlessly focus on objects at a full spectrum of distances.
Multifocal Lens Implants (ReStor, ReZoom)
Similar in concept to bifocal contact lenses, multifocal lens implants are designed with both near and distance viewing zones. Unlike bifocal or “progressive” spectacles, these Presbyopia lens implants do not require the patient to gaze in different directions (ie: up for distance, down for near) in order to utilize each zone of the lens implant. The first lens FDA approved for this purpose was the Array lens. The biggest problem with this lens was the incidence of night vision disturbances in some patients. Refinements in lens designs have improved upon this initial model such that newer multifocal lenses are better tolerated. The most popular multifocal lens implants are the ReStor and ReZoom implants.
Lens Implant Conclusions
While there are advantages and disadvantages to any lens implant style, the vast majority of patients who receive presbyopia surgery lens implants are able to function without glasses or contact lenses for all, or nearly all, of their daily tasks. No matter which style of lens implant is selected, it is important that the power (strength) of the implant is appropriate for your eye. A sequence of sophisticated preoperative tests and calculations are done in order to maximize the accuracy. If the lens implant power is significantly off target, laser vision correction can be performed once the eye heals in order to fine tune the focus (Bioptics).

Most patients undergoing cataract or Clear Lens Exchange surgery are candidates for lens implants that can provide them with both driving and reading vision without the need for glasses or contact lenses. Dr. Davidorf presented his results to the American Society of Cataract and Refractive Surgery in March, 2006; his findings are detailed in this Los Angeles Daily News article.
