Breakthroughs in the design of multifocal lenses have led to the development of two new lenses the ReSTOR® and the ReZoom™. The monofocal lenses used routinely in cataract surgery are excellent, but only allow for focus of distance or near objects, not both. These two new intraocular lenses are able to focus light at various distances therefore reducing the need for glasses for both seeing far objects(street signs) and for near vision tasks (reading your watch). This represents a great advantage over the traditional monofocal intraocular lens.
How Do Multifocal Lenses Work?
The ReSTOR lens possesses a blend of different focusing powers within the lens design, known as “apodization”. This lens has a powerful reading prescription built right into the lens body. It allows patients to see at the distance via the distance focus and at near using this blended reading prescription. For more information on the ReSTOR lens please visit: www.acrysofrestor.com.
The ReZoom lens uses a combination of different near and far zones within the lens body. Each ringed zone is able to focus at a different distance, some near and some far. This allows for a variety of focusing power all within the same lens. As such, patients may get far, near, and intermediate vision without using glasses for a majority of their activities.

Is Cataract Surgery Different with These Multifocal Lenses?
No. The cataract surgery is performed in the same thirty minute procedure. The only difference is that your surgeon implants a multifocal lens instead of a monofocal lens. This results in the same comfort and short recovery time that patients experience with cataract surgery.
Am I a candidate?
Multifocal lenses are well suited for patients over the age of 50 who have reduced vision due to cataracts and wish to achieve more independence from glasses for distance and near vision that traditional monofocal lenses allow. Prior eye disease and medical history will be carefully considered. Based on each patient’s activities and goals your eye doctor will determine which of these new lenses matches your needs. A careful review of your medical history and eye symptoms will also be completed. Not all patients may be candidates for this new technology. The information provided above may not apply to all patients who receive this new technology and results may vary. Some patients who receive these new lenses may still require glasses after surgery for some activities. Please ask your eye surgeon if you would beneﬁt from cataract surgery using these new multifocal or accommodative lens technologies.
