Impaired vision - as light passes though the cataractous lens, it is diffused or scatters. The result is blurred defocused vision
Introducing a breakthrough in vision surgery. Now there's a revolutionary new way to potentially leave your glasses behind – introducing the AcrySof® ReSTOR® intraocular lens (IOL), a breakthrough in vision surgery. AcrySof® ReSTOR® has been uniquely designed to improve vision at all distances – up close, far away and everything in-between – giving cataract patients their best chance to live free of glasses.
As we grow older, our bodies mature and change naturally. Within the aging eye, these changes often develop into conditions that impact the quality of your vision. But if you're experiencing age-related visual problems, don't give up – with successful treatment, it may be possible to have clearer, brighter and sharper vision than you've had for a long, long time.

Cataracts – A cataract is a change in the clarity, or a "clouding," of the lens in your eye. Your crystalline lens, which is made mostly of protein and water, can become clouded enough to prevent light and images from reaching the retina. A cataract can be the reason sharp images become blurred and seeing things at night becomes more difficult. More than half of all Americans age 65 and older have a cataract, and cataracts are the leading cause of treatable blindness. For more on cataract treatment, read about cataract surgery.
Cataract-aged patients may also have a condition known as presbyopia.
Presbyopia – As people enter their 40s, they may experience blurred vision when performing everyday "close-up" tasks such as reading, sewing or working at the computer. This condition, called presbyopia, occurs as the lens in the eye becomes less flexible, and the muscles controlling the lens weaken. This is why some people need reading glasses or need to hold objects farther away to see them.
Lens is a single-piece lens. The arms that keep the lens centered and secure are made of the same soft acrylic material as the lens body.
Cataract surgery is an outpatient procedure that will only take a few hours. When you arrive, your eyes may be treated with eye drops and anesthetic to minimize any discomfort during the operation.
During this routine operation, a small incision is made in the eye. Your surgeon will use a tiny instrument (about the size of a pen tip) to remove your clouded lens. This can be done with either an AquaLase®* device, which uses gentle pulses of fluid to wash away your cloudy lens, or an ultrasonic instrument that breaks up and gently removes your cloudy lens (called phacoemulsification). Once this is accomplished, your surgeon will insert an artificial intraocular lens (IOL) into your eye.
After the procedure, you'll be given a short time to rest. Then, the very same day, you can go home. Within the next 24 hours, your doctor will probably want to see you for an evaluation. Drops will be prescribed to guard against infection and to help your eyes heal. For a few days, you may need to wear a clear shield, especially at night, to prevent you from rubbing your eye
Until recently, life without reading glasses or bifocals was not an option for most cataract patients. You now have an option. The AcrySof® ReSTOR® IOL is a unique technological innovation that can provide you with quality vision throughout the entire visual spectrum – near through distance – with increased potential independence from reading glasses or bifocals!

As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and everything in-between. The ability to quickly change focus throughout this range of vision is called accommodation. Unfortunately, this ability diminishes as we grow older¹, causing us to become dependent on bifocals or reading glasses. However, the AcrySof® ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized diffractive and refractive technologies. Similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.
Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near through distance vision.
Refraction involves the redirection of light passing through the lens, to focus on the retina. The refractive region of the AcrySof® ReSTOR® IOL bends light as it passes through the lens to a focal point on the retina. This outer ring of the AcrySof® ReSTOR® IOL surrounds the apodized diffractive region and is dedicated to focusing light for distance vision.
For most patients, the AcrySof® ReSTOR® IOL delivers excellent near and distance vision, and good intermediate vision without reading glasses or bifocals. In fact, with this increase in vision quality, AcrySof® ReSTOR® IOL patients would be able to pass the visual acuity portion of the driver's license exam in most states.
Finally, quality vision and true freedom from glasses for 80% of patients
During the AcrySof® ReSTOR® IOL clinical studies, patients experienced lifestyle enhancement through quality vision, and greater freedom from reading glasses and bifocals. In fact, according to the AcrySof® ReSTOR® clinical studies, four out of five patients with the AcrySof® ReSTOR® IOL reported never wearing glasses following cataract surgery in both eyes, compared to only 1 out of 10 patients with monofocal lenses. This is the highest level of freedom from glasses ever demonstrated in an IOL clinical trial.
Additionally, the AcrySof® ReSTOR® clinical studies indicated that nearly 94% of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® ReSTOR® IOL implanted again.
