Cataracts

The lens of the eye is essential for clear vision. Located behind the pupil and iris, the natural lens which is normally clear can become cloudy and dense. This is known as a cataract. Cataracts are the most common cause of vision changes in people over forty. Cataract surgery is one of the safest and most effective surgeries performed today.

When cataracts have begun to seriously affect your vision and quality of life, it may be time to consider cataract surgery.

What causes cataracts?

Certain risk factors make a person more likely to develop a cataract. These include:

  • Advanced age
  • Smoking
  • Certain steroid medications
  • Family history
  • High blood pressure
  • Radiation exposure
  • High sunlight exposure
  • Diabetes
  • Eye injury
  • Frequent eye infections
  • Obesity

What are the symptoms of cataracts?

In general, those who suffer from a cataract report vision that is:

  • Lacking in color
  • Blurry
  • Unfocused
  • Sensitive to light
  • Dimmed
  • Yellowed

Cataract surgery

The surgery is generally a simple outpatient procedure. The surgeon will make a tiny incision in the eye, remove your eye's clouded lens, and replace it with an implant known as an IOL or intraocular lens. The results are permanent and the actual surgery takes only minutes. Most of our patients are back to normal activities the very next day.

Implant Options and Surgery

AcrySof ReSTOR Multifocal

All of the surgeons at the Midwest Center for Sight are certified to provide AcrySof ReSTOR, a breakthrough intraocular lens implant (IOL) that is designed to replace cataracts and correct presbyopia at the same time. Presbyopia is the primary reason many patients need reading glasses as their eyes age. The goal of these lenses is to provide clear vision near, far, and everywhere in between. In fact, a large number of our ReSTOR patients report never wearing glasses after receiving these IOLs.

How does the AcrySof ReSTOR lens differ from other IOLs?

The AcrySof ReSTOR lens is a multifocal IOL. Traditional IOLs are monofocal. As the name implies, monofocal lenses can only give you clear distance vision, which means reading glasses are still needed.. With the ReSTOR multifocal implant you will be independent of any glasses or contact lenses.

AcrySof Toric

The AcrySof Toric intraocular lens implant (IOL) is designed to correct the astigmatism that may be distorting your vision. If you need cataract surgery and also have astigmatism, you may be an AcrySof Toric IOL candidate, as these IOLs can help you correct both problems.

The result is typically improved distance vision and less dependence on glasses. However, most patients still need corrective lenses for near and intermediate tasks.

AcrySof IQ Monofocal

Our Surgeons at the Midwest Center for Sight are experts at implanting the AcrySof IQ Monofocal intraocular lens (IOL), which is designed to improve image quality after the removal of a cataract. A monofocal IOL is intended to provide clear distance vision, but most monofocal IOL patients will likely need corrective lenses for some tasks, such as reading, sewing or computer work.

Most eyes contain slight imperfections that are referred to as aberrations. A common aberration for cataract patients is called a spherical aberration. This causes a gradual reduction in image quality and visual function. The AcrySof IQ Monofocal lens is designed to reduce spherical aberration, increase contrast sensitivity, and improve functional vision.

AcrySof IOLs are the most commonly used brand worldwide and unique in their ability to filter high-energy blue light.

Visiogen Synchrony Multifocal

Dr. James Katz, a leading cataract and LASIK surgeon, is the first ophthalmic surgeon in the Chicago area to participate in the FDA clinical trial for an investigational dual-optic accommodating intraocular lens, Synchrony by Visiogen Inc.

Selected in 2006, Dr. James Katz is one of only ten doctors in the nation to participate in the trial. The objective of the trial is to evaluate the safety and effectiveness of the lens in patients undergoing cataract surgery as well as its potential for functional near vision without glasses. During the trial, Dr. Katz will carefully observe his Chicago Visiogen Synchrony patients to learn about the benefits of these IOLs.

To learn more about receiving Visiogen Synchrony IOLs in Chicago and to see a demonstration on how they work, contact us at 847-824-3127.

Crystalens

As an experienced Chicago Crystalens specialist, Dr. James Katz implants these lenses as part of cataract surgery and as part of the refractive lens exchange procedure. In fact, Dr. James Katz is one of the few refractive surgeons in the Chicago area who is certified to use such a wide variety of breakthrough intraocular lens implants (IOLs).

How does crystalens accommodating lens differ from other IOLs?

The first and only lens of its kind that is FDA-approved, the crystalens accommodating lens takes its design cues from nature. The lens's flexible hinge enables movement much like your natural lens when you need to focus on something far away, close-up or at an intermediate distance. It works in concert with the eye's muscles to flex or "accommodate" for near, distant or intermediate focus.

No lens comes closer to mirroring the function of your natural lens. More than twice the number of patients implanted with a Crystalens IOL could see at all distances compared to a standard intraocular lens implant. Most of our Crystalens Chicago patients are able to read a newspaper, see their computers, and read the clock across the room without glasses.

Safe and Effective

Cataract surgery is one of the safest and most effective procedures performed today.

Is cataract surgery painful?

Cataract surgery is an outpatient procedure done with very little discomfort. Most of our patients are back to their normal activities the very next day. Typically the procedure is performed on one eye at a time approximately one month apart.

Cassini

Cassini's unsurpassed accuracy and precision makes it indispensable for your cataract surgery. The Midwest Center for Sight is one of the only offices in the country to have this technology available for all of our surgical patients.

Cassini technology employs red, green and yellow LEDs that are each positioned in a unique relationship to four of its neighbors, giving each one a 'gps-like' coordinate. Cassini uses the ray-tracing principle to measure the relative position of each point, using the three different colors as 'triangulation' points. An elevation increases the distance between points (x) and a depression decreases the distance between points (y). This is displayed in the figure.

Because Cassini does not use edge detection in its measurement algorithms, smeared or double reflected LEDs cannot skew the results in any direction. This allows the Cassini to effectively image all corneas from regular to highly irregular, and dry eyes.
