| Lens Implants — Crystalens, ReZoom and ReSTOR |
Aging diminishes the eye’s ability to vary the focus for near objects, called presbyopia. New generation lens implants replace the eye’s natural lens, offering superior vision, both near and far—giving patients freedom from spectacles for most activities including reading and distance vision for driving.
Three new lens implants have recently been FDA-approved for correction of both distance and reading vision — Crystalens, ReZoom and ReSTOR. Each type works differently, and should be fit according to your individual needs. Our surgeon has extensive experience and takes pride in helping each patient make an unbiased, informed decision on an implant that will provide a lifetime of clear vision. Please call or email us to schedule a free consultation and find out which lens implant is right for you. |
| Lens Implants |
The standard lens implants are generally chosen to give good distance vision, but then patients are dependent on glasses for all their near activities. In the recent couple of years, new lens implants can now provide both reading and distance vision without glasses for people undergoing cataract or refractive lens implant surgery.
Three new lens implants have been FDA-approved recently for correction of both distance and reading vision. Each of these implants works slightly differently, and not all implants are right for all patients. This page is designed to help people interested in these new-technology lens implants to understand the similarities and differences between them. Our surgeon has extensive experience takes pride in helping each patient make an unbiased, informed decision on an implant that will provide a lifetime of clear vision.

| Crystalens® - 'Auto-focusing' for Far, Near, and Everything In-Between |
| The Crystalens implant (made by Eyeonics, Inc.) can give reading vision (within 1-2 feet), arm's length (2-3 feet), and distance vision without glasses because this implant actually adjusts its position within the eye as the eye looks from far to near subjects, much like an 'auto focus' mechanism on a camera. The Crystalens is powered by the same ciliary body muscles that move and focus the eye's own natural lens. Its unique, hinged shape allows for this lens movement and gives a seamless transition from far to arm's length to near vision. Most people with the Crystalens have clear far vision (driving, television) and intermediate vision (arm's length, computer screen) without any glasses. About 95% of people can also read newsprint without glasses. Some people do need glasses for fine print, especially in dim light. Of the three lenses, the Crystalens is most likely to provide the best vision for driving at night. |
| ReZoom® - Progressive Lens Inside the Eye |
| The ReZoom lens (made by Advanced Medical Optics, Inc.) is a non-moving lens implant. It gives near (1-2 feet), arm's length (2-3 feet), and distance vision simultaneously because it has three focusing zones. Light entering the eye passes through all three of these zones simultaneously. This means there is no 'learning curve' for reading with this lens. Distance and reading vision are available almost immediately. However, some patients may have difficulty with driving at night because of glare from oncoming lights. This can occur with any lens implant but is more likely with implants that focus light in two or more places at once. Just as progressive spectacle lenses can cause distortion under certain conditions, the ReZoom lens may not give perfect vision in dim light situations. The ReZoom lens gives generally satisfactory arm's length (computer screen, arm's length) vision but may not yield perfect vision for reading very small print up-close. |
| ReSTOR® Lens - The Space-Age Bifocal |
| Like ReZoom, the ReSTOR lens is a non-moving lens implant. It also can give distance and near vision simultaneously. Rather than having three separate focusing zones like ReZoom, however, the ReSTOR lens focuses vision using an 'apodized' surface. This high-tech manufacturing process gives the lens a gradual blending of focusing power throughout the entire lens surface. With the ReSTOR lens, 97% of people can see both distance objects (road signs) and near objects (reading material within 1-2 feet) without difficulty, especially in good light. Arm's length vision (the computer screen, for example) at 2-3 feet is less clear, and some people may need glasses for these kinds of tasks. In dim light, the lens is designed to give better distance vision. However, 5% of people with ReSTOR do notice significant haloes or glare around lights at night. For people who do a great deal of night driving, both ReZoom and ReSTOR may not be ideal choices. |
