Lens Replacement Surgery featuring Premium Intraocular Lenses (IOLs).
Artificial lenses (IOLs) are implanted in the eye to replace natural lenses that have been damaged by cloudy cataracts or presbyopia. Until recently, IOLs were only available to correct distance vision. These monofocal lenses helped improve distance vision after cataract surgery, but patients still needed glasses or contact lenses for near vision activities like reading and playing cards. Now, advancements in technology have produced lenses that allow patients to see clearly at all distances -- near, far and many distances in between. Premium IOLs such as Crystalens® and ReZoom™ preserve distance vision and correct presbyopia so cataract surgery patients -- and patients seeking treatment for presbyopia alone -- can enjoy clear sight without relying on glasses.
The procedure to replace a patient's natural lens with a multifocal IOL is the same as that used in cataract surgery.
What is the Crystalens®?
The Crystalens® is an FDA-approved intraocular lens for the visual correction of adults with cataracts (clouded lenses) with or without presbyopia, or lenses that have aged or become more rigid.
The Crystalens® was modeled after the human eye. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. The Crystalens® dynamically adjusts to your visual needs.
The Crystalens® accommodating intraocular lens is made with hinges on each side that are designed to allow the optic, or the part of the lens that you see through, to move back and forth as you constantly change focus on images around you. The crystalens is a small lens enabling it to flex or bend as you focus your vision.
Crystalens® is:
- The first and only FDA-approved accommodating intraocular lens
- The only lens that uses the natural focusing ability of the eye
- The only lens that provides a single focal point throughout a continuous range of vision from far to near, and everything in between
Few patients with Crystalens® have experienced glare, halos and night vision problems. Crystalens® focuses only one image to the back of the eye, unlike a multifocal lens that projects multiple images that are not entirely in focus, requiring your brain to "adjust" to the differences. In addition, Crystalens® vision is sharp and crisp because 100% of the light rays are available and distributed – when you need it.
The effectiveness of the Crystalens® was proven in clinical trials:
- 98.4% of patients implanted with Crystalens® in both eyes could pass a driver's test without glasses
- 100% could see intermediate (24" to 30") without glasses, the distance for most of life's activities
- 98.4% could see well enough to read the newspaper and the phone book without glasses
- 74% of patients never or almost never wore eyeglasses
Significantly more patients implanted with a Crystalens® (88.4%) could see better at all distances than patients implanted with a standard IOL (35.9%).
Long-term experience means a safe and effective procedure – some patients have continued excellent vision 5 years after implantation with the Crystalens®. More than 40,000 Crystalenses® have been implanted worldwide.

The ReZoom® multifocal IOL helps patients focus clearly on objects at a range of distances and in varied light conditions. Featuring a patented lens design called Balanced View Optics™ Technology, the ReZoom lens has five spherical segments with smooth transitions in between so the eyes focus seamlessly from one distance to the next. The center of the lens is optimized for bright light and distance vision, while the fourth zone supports near-vision in a variety of light conditions, and the outermost zone accommodates for low-light distance vision (such as when driving at night). The ReZoom is also specially designed to reduce internal reflections and minimize glare.
If you have been diagnosed as having cataracts and are experiencing one or more of the following vision problems, you may be a candidate for the ReZoom multifocal IOL:
- Difficulty reading
- Difficulty seeing close objects
- Difficulty driving, especially at night
- Frequent changes in glasses prescription
- Need for bifocals
