Lifestyle IOL'S

Presbyopia is a condition that most people over the age of 40 experiences that result in difficulty seeing up close without the aid of bifocals, trifocals, or reading glasses. This age-related condition is believed to be caused by a hardening of the lens inside the eye, making it difficult for the eye’s muscles to change its focus.

Over time, the lens becomes cloudy and develops into a cataract. It is said that, if we live long enough, we will all develop cataracts. The only way to treat cataracts is to remove and replace them with an Intraocular Lens (IOL).

Until recently, the primary option was to receive a fixed “fixed focus” IOL. Patients who received this type of IOL typically had both eyes corrected for distance vision but usually still required glasses for intermediate and near vision.

If you are experiencing presbyopia or cataracts, you may be a candidate for one of the new technologically advanced IOLs that can provide a full range of vision. This means that you can read and see clearly in the distance and everything in-between, with little or no dependence on bifocals, trifocals, or contact lenses. It’s almost like having a bifocal or progressive lens inside your eye.

Depending on the technological features of these IOLs, they may be described as “Accommodating IOLs,” “Apodized-diffractive IOLs,” or “multifocal IOLs.” Each of these lenses has some advantages and disadvantages. Which one is best for you depends on the unique characteristics of your eye as well as your lifestyle needs. You and your doctor will decide together which lens is more advantageous for you.

Tecnis® IOL

Cataract surgery, which replaces the eye's cloudy lens with an artificial clear lens (called an intraocular lens, or IOL), is the most common operation in the U.S. More than half of adults over age 65 have some degree of cataract development, which causes painless, progressive vision loss. People 65 and older are also more likely to be involved in car crashes than people in their 30s, 40s and 50s. Fortunately, new technology has allowed for the development of an innovative night vision-enhancing IOL that can help elderly drivers with cataracts avoid accidents.

Tecnis® IOL was designed to provide cataract surgery patients with high-quality vision comparable to that of young people. Its main concern is improving safety with vision correction. It is meant to improve functional vision - the ability to see objects in varying light conditions - especially at night and twilight and in rain, snow and fog. This means improved night vision and reduction of spherical aberrations, an undesirable scattering of light that is a common side effect of cataract surgery.

The Tecnis lens was approved as an IOL by the FDA in 2002. In April 2004 it was approved again as a driving aid. Since then, countless cataract patients have been able to achieve clear vision that allows them to maintain their active and healthy life.

ReStor® IOL

AcrySof® IQ ReSTOR® IOL is an intraocular lens that provides a full range of vision for patients after cataract surgery, significantly decreasing their dependence on glasses or contact lenses. The ReSTOR IOL replaces the natural lens of the eye which has been removed during surgery. Its optic design enables it to bend light to a focal point of the retina, facilitating distance vision. By distributing light on the retina in such a way that images at various distances are clearly perceived, it provides multifocal visual clarity.

The ReStor IOL has been shaped using a special process called apodized diffraction to provide increased depth of focus. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. Apodization is a process through which such light is gradually tapered to create a smooth transition which allows accurate focus at various distances.

The lens of the ReSTOR IOL is convex on both sides, or biconvex, and is made of soft plastic so that it can be folded prior to insertion. This allows the surgeon to make an incision smaller than the diameter of the lens itself. After the IOL has been surgically inserted into the eye, it gently unfolds to restore vision. The IOL is constructed with supporting arms which provide for proper positioning in the eye.

ReZoom™ IOL

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

Toric IOL

Intraocular lenses are used to correct vision problems during cataract surgery by replacing the old, damaged lens with an artificial lens that clears up and corrects vision, often leaving patients with little to no dependence on glasses. While cataract surgery corrects cloudy lenses, it still leaves patients with astigmatism with distorted vision. Toric IOLs are specially designed to correct astigmatism along with overall vision during cataract surgery, offering complete vision correction.

Before Toric IOLs, people with astigmatism would need to undergo corneal refractive surgery after their lenses were implanted, or would remain dependent on glasses or contact lenses. The advanced Toric IOLs correct the imbalance caused by an irregular cornea shape in patients with astigmatism. There are several different types of FDA approved Toric IOLs, including AcrySof® Toric Lenses, which can correct up to 3 diopters of astigmatism.

The risks of a Toric IOL include poor vision as a result of the lens rotating out of position, although this risk exists with any type of intraocular lens. Toric IOLs are considered safe for most patients with astigmatism and are the only solution to correct both cataract and astigmatism vision problems. Talk to your doctor to learn more about these lenses and find out if you can enjoy the benefits of Toric IOLs.
