A cataract is a common condition that causes a clouding of the eye’s natural lens, and affects millions of people each year, including more than half of all Americans over the age of 65. Cloudiness develops as a result of a buildup of protein in the lens.
Cataracts cause a progressive, painless loss of vision. The lens clouds naturally as we age, causing people over the age of 65 to see a gradual reduction of vision. However, cataracts are not considered part of the natural aging process and are a serious condition that requires prompt medical attention. The exact cause of cataracts is unknown, although it may be a result of injury, certain medications, illnesses (such as diabetes), prolonged exposure to ultraviolet light and smoking.

Symptoms of Cataracts
Patients with cataracts often do not experience any symptoms when the condition first develops. Cataracts will continue to progress with no apparent pain, although patients may experience:
- Blurred or hazy vision
- Double vision
- Poor vision in bright light
- Seeing halos around lights
- Poor vision at night
- Yellowish tinged vision
- Frequent changes in eyeglasses or contact lens prescription
What Does Cataract Surgery Involve?
Cataract surgery is a minimally invasive procedure that involves numbing the eyes with anesthesia and then making a tiny incision into which an ultrasonic probe is inserted. The probe breaks up, or emulsifies, the cloudy lens into tiny pieces and then suctions them out of the eye. Once the cloudy lens has been removed, a new artificial lens is implanted into the eye. This lens is known as an intraocular lens (IOL), and can often be inserted through the same incision that the old lens was removed from.
How Long Is The Cataract Surgery Procedure?
Surgery usually takes only a few minutes to perform and is painless for most patients. After the procedure, a patch may be placed over the eye and you will be asked to rest for a while.
What Is The Recovery Like?
Patients can return home the very same day, but will need someone to drive them home. For the next few days, you may experience itching, mild discomfort, fluid discharge and sensitivity to light and touch.
Your doctor may prescribe eye drops to help the healing process and to reduce the risk of infection.
Ensuring the Best Results
There are several different IOLs available to help each patient achieve the best possible results from his/her cataract surgery. Multifocal IOLs allow for full vision correction at near, intermediate and far distances, completely eliminating the need for eyeglasses or contact lenses in most patients. Some IOLs can also correct astigmatism.
These choices were not always available for cataract patients. In the past, cataract surgery only involved monofocal lenses, which could only focus on objects near or far, but could not adjust to accommodate varying distances. These patients still had to rely on glasses or contact lenses after surgery in order to see clearly at all distances, especially in older patients suffering from presbyopia.
What Are Cataracts?
Cataracts are characterized by clouding of the eye’s natural lens, the transparent film that focuses the images as seen by the eye on the light-sensitive retina at the back of the eye. This condition usually occurs when proteins form abnormal clumps in the lens. When these clumps enlarge, they begin to interfere with vision by distorting the passage of light through the lens. The result is an increasing cloudiness that affects vision, especially at night.
What Are The Causes of Cataracts?
The effects of aging, combined with lifelong sun exposure (especially here in the Pacific Northwest where we spend a lot of time outdoors), cause cataracts to develop usually beginning around age 40. The cloudiness progresses slowly, not usually affecting vision until after the age of 60.
Other contributing factors to the development of cataracts are smoking, eye trauma, chronic diabetes, radiation treatments, and corticosteroid medications. Cataracts can be congenital, usually due to infection, but those cases are very rare.
How Can I Tell If I Have Cataracts?
Most people with cataracts have had them long before they know it. Once the protein clumps start to become large enough to cloud the vision is when the condition begins to make itself known. There is no pain associated with cataracts. Because the development is very gradual, patients often don’t realize they have cataracts. But when they reach a certain point of development, various symptoms will show themselves: cloudy, blurry vision; double vision; seeing halos around lights; inability to see bright color; increased sensitivity to glare; and distortion, which can be akin to looking at the world through a dirty window.
