Cataract Surgery

A cataract is a clouding of the normally clear, transparent lens of the eye.  A cataract is not a tumor or growth of new tissue over or in the eye, rather a fogging and loss of clarity of the lens itself. When a cataract forms, the lens is no longer able to focus the light clearly and your vision becomes cloudy. An early cataract may cause few problems with vision. If the cataract gets worse, sight may be partially or completely lost until the cataract is removed.

Although cataracts result from many conditions, the most frequent cause is the natural aging process. Other causes may include eye trauma, chronic eye disease, and other medical conditions such as diabetes.

Cataracts can take from a few months to several years to develop. Certain medications can accelerate the development of cataracts. Sometimes, the cataract stops developing in its early stages and vision is only slightly decreased. But if it continues to develop, vision is impaired, and surgical treatment is required.

Pepose Vision is a worldwide leader in the research of cataract treatment and removal. We utilize the latest technology and provide the convenience of a surgery center in our building. Our surgeons are involved in your entire surgical process, including pre-op, and are recognized each and every year among the very best.

How do I know if I have cataracts?

You may not notice any symptoms with early cataracts. As a cataract becomes more advanced, decrease in clarity of vision, not fully correctable with glasses, is noticed. There is a loss of contrast sensitivity, so that shadows and color vision are less vivid. Disturbing glare may be noted as light into the eye is scattered by the cataract. Halos may be observed around lights. Night vision will be diminished. In certain types of cataracts, double vision may be noted in the affected eye. Some patients note that they require frequent changes in their eyeglass or contact lens prescriptions and may be aware that their near vision is improving as their distance vision declines.

A cataract does not routinely cause discomfort or pain in the eye or alter the external appearance of the eye.

The only way to determine if your vision issue results from a cataract is to visit an eye care professional for a complete examination. At Pepose Vision Institute, we use state-of-the-art diagnostics to evaluate your eyes. Our wavefront diagnostic technology generates thousands of data points about your eyes in a matter of minutes. We are the only cataract surgeons in the Bi-State area to provide this level of thoroughness during your exam.

How do you treat cataracts?

The only effective treatment for a cataract is surgery to remove the diseased, cloudy lens. Neither diet nor medications have been shown to stop cataract formation.

In a cataract operation, the eye’s natural lens is removed. Vision can then be obtained by implanting a permanent intraocular lens (IOL), which replaces the natural lens. This artificial lens is made of plastic and is usually inserted at the same time the cataract is removed. Depending on the individual case, the lens is placed directly behind or, less frequently, in front of the iris, the “colored” part of the eye.

There have been remarkable advances in the treatment of cataracts, namely in the use of premium lenses (IOLs) that not only help make vision clearer but can also help improve near and far vision.  Often patients that select these lenses do not need to use their glasses anymore.
