Premium lenses will help reduce or eliminate your need for glasses after cataract surgery. Our doctors use two different types of premium intraocular lens implants - ReSTOR and Crystalens. Each lens works on different optic principles allowing it to focus both near and distant images. Your doctor will help you decide which lens will best meet your vision goals after cataract surgery.

AcrySof® ReSTOR®

What is it?

The AcrySof ReSTOR Apodized Diffractive Optic Posterior IOL (ReSTOR) is a permanent artificial lens. ReSTOR is implanted in the eye to restore vision after the natural lens is removed because of cataract with or without presbyopia (over 40 vision).

The ReSTOR lens is convex on both sides and made of a soft plastic. It is folded and inserted into the eye through a tiny incision smaller than the optic diameter of the lens. After insertion, the lens gently unfolds to restore vision. The supporting arms (haptics) of the lens maintain proper positioning within the eye.

How does it work?

The AcrySof ReSTOR IOL replaces the natural lens. It has a patented optic design using apodization, diffraction and refraction technologies. The apodized diffractive optic design gives it the ability to focus light correctly on the retina for images at various distances without mechanical movement of the lens.

• Apodization is a gradual reduction or blending of the diffractive step heights.
• This unique technology optimally manages light energy delivered to the retina because it distributes the appropriate amount of light to near and distant focal points, regardless of the lighting situation.
• Apodized diffractive optics are designed to improve image quality while minimizing visual disturbances. The result is an increased range of quality vision that delivers a high level of spectacle freedom.

When is it used?

The AcrySof ReSTOR IOL is used in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased independence from glasses following cataract surgery.

What will it accomplish?

The AcrySof ReSTOR IOL has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses in patients who have undergone cataract surgery.

Crystalens®

What is Crystalens?

Crystalens is an accommodating intraocular lens that, unlike a standard IOL, can treat both a person's cataracts and presbyopia-loss of near and intermediate vision. You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses. Crystalens not only treats your cataracts (a clouding or hardening of your lens), but can also reduce or eliminate your dependence on glasses. It does so by recreating accommodation similar to your eye's natural lens. The unique Crystalens can reduce or eliminate glasses for most activities, including: reading a book, working on the computer, and driving a car.

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. Crystalens dynamically adjusts to your visual needs.

Crystalens is designed to allow the optic, or the central circular part of the lens that you see through, to move back and forth as you constantly change focus on images around you. Crystalens flexes as you focus your vision.

Crystalens is:

• The first and only FDA-approved accommodating intraocular lens
• The only FDA-approved intraocular lens that uses the natural focusing ability of the eye
• The only FDA-approved presbyopia correcting IOL for cataract patients that provides a single focal point throughout a continuous range of vision

Few patients with Crystalens have experienced problems with glare, halos and night vision. Crystalens focuses only one image to the back of the eye, unlike a multifocal lens that projects multiple images, requiring your brain to "adjust" to the differences.

The effectiveness of Crystalens was proven in clinical trials:

• Significantly more patients implanted with a Crystalens (88.4%) could see better at all distances than patients implanted with a standard IOL (35.9%).
• Most patients have continued to report excellent vision 7 years after implantation with Crystalens. More than 100,000 Crystalens implants have been implanted worldwide, and that number is growing daily.

Crystalens accommodates like the natural lens. After implantation of Crystalens, most patients will see brighter and clearer from distance, intermediate to near like they did when they were younger.

ONLY FDA-Approved accommodating IOL

Crystalens was the first presbyopia correcting IOL introduced into the United States market and is currently the only FDA-approved accommodating IOL. Crystalens addresses the limitations of standard monofocal IOLs and multifocal IOLs by providing the following advantages to patients:

• Provides a Broad Range of Vision: Crystalens moves and changes shape using the eye's natural focusing mechanism, instead of remaining fixed and stationary within the eye. This movement, or accommodation, allows the eye to focus on objects across a broad range of distances to reduce or eliminate dependence on glasses. In particular, this accommodation provides significant advantages in addressing intermediate vision.
• Maintains Clarity of Vision: Unlike multifocal lenses, Crystalens directs all available light received by the eye to a single focal point, comparable to that of a healthy natural lens.
• Patient Adjustment Not Required: Crystalens produces a single image consistent with normal vision, meaning patients do not need to neuroadapt to viewing multiple images. Patients also do not need to tolerate or adjust to high levels of halos and glare often associated with multifocal IOLs.
