When patients are diagnosed with cataracts, most doctors agree that the time to have cataract surgery is when the quality of their patient's vision begins to interfere with the things they like to do most in life. Thanks to recent advancements, cataract surgery not only allows you to "ReZoom" life, it may allow you to see young again with the latest advancements in multifocal lens implant technology.

How Age Affects Vision

As we age, beginning around the age of 40, the natural lens inside the eye begins to harden and lose its flexibility. This reduces the eye's ability to change its focus from near to intermediate, to distance, and back again. This is known as "loss of accommodation" or "presbyopia," and its earliest symptom is difficulty seeing things up close. Bifocal and even trifocal glasses become necessary for some people to see clearly at all distances.

As the natural lens of the eye continues to deteriorate, it starts to become cloudy or brown. Vision becomes blurry, and colors lose their brilliance. At first, frequent changes in glasses prescriptions can help, but left untreated, cataracts can lead to blindness. The only way to see clearly after a cataract matures is to have it removed and then replaced with an intraocular lens, or IOL.

Surgery to remove the natural lens is one of the most commonly performed procedures today, with over 14.2 million cataract and lens implant procedures performed annually. IOLs have been used for around 50 years to restore vision after lens removal.

Greater Freedom from Glasses

Until recently, patients undergoing lens implant surgery receive a monofocal, or single focus IOL. Monofocal IOLs implanted in both eyes generally provide excellent distance vision while patients often need spectacle correction for near and intermediate vision. In the late 1990s, Advanced Medical Optics (AMO) introduced its first multifocal IOLs designed to provide multiple points of focus, thereby dramatically reducing the need for bifocal or trifocal glasses after surgery.

Today, with its many optical design enhancements, AMO's second-generation ReZoomMultifocal IOL is providing patients with a full range of vision and greater independence from glasses or contact lenses than ever before. Clinical studies show that 92% of those receiving the ReZoom™ lens technology "never," or "only occasionally," need to wear glasses.

The ReZoom Implant Procedure

Surgery typically takes only 15 to 30 minutes. The procedure involves making a tiny incision on the edge of the cornea and gently breaking up and removing the natural lens. Once the lens is removed, the ReZoomMultifocal IOL is folded and inserted through the small incision. It is then positioned in the same location the natural lens occupied. The incision is then closed and remains tightly sealed due to the outward pressure inside the eye.

The ReZoomMultifocal Lens Technology

Balanced View Optics™ Technology literally provides multiple focal points so you can see well at a variety of distances. The ReZoomMultifocal lens has five uniquely proportioned visual zones designed to provide clear vision for different light and focal distances.

 

Vision After ReZoomMultifocal Lens Implantation

Most people can "ReZoom" their normal activities the next day. Everyone heals at a different rate, but in most cases, vision is improved within 24 hours and continues to improve as your eye heals and you become more accustomed to using your multifocal lens.

A visual side effect patients may experience is halos, or glare around lights, especially at night. The degree of these side effects varies from patient to patient and is most noticeable during the first few months after the procedure. For most people, these side effects diminish over time and do not impair your ability to function visually at night. Most patients report that the ability to see at multiple distances far outweighs any visual side effects they may experience.

Although you might prefer to use glasses for prolonged reading, to read small type, or to drive at night, most people report they can go to the store or conduct most of their daily activities without depending on glasses. The full benefit of having the ReZoomMultifocal IOL lens implant will be even more noticeable when both eyes have been treated.

The First Steps to Resuming Life

If you suffer from poor vision or think you might have a cataract, you should make an appointment to have a complete eye examination. Once it is determined that you are a good candidate for the ReZoomMultifocal IOL, you will be given additional information about the possible risks, complications, and costs involved with the procedure. Be sure to have all of your questions answered before giving your consent to have surgery.
