A cataract is a clouding of the natural lens inside the eye. Located behind the iris, the natural lens helps focus light on the back of the retina, which sends the images on to the brain. When the lens is clouded, it can prevent light and images from effectively reaching the retina.
Could you have a cataract?
Symptoms of a cataract can include:
- Decreasing vision with age
- Blurred or double vision
- Seeing halos around bright lights
- Difficulty seeing at night
- Vision that worsens in sunlight
- Difficulty distinguishing colors
- Poor depth perception
- Frequent prescription changes
- Difficulty reading
These symptoms also can be a sign of other eye problems. If you have been diagnosed with cataracts or are struggling with cloudy vision in one or both eyes, you are not alone. Most cataracts are related to aging, typically beginning to form around age 55. In fact, by age 65, more than half of all Americans either have a cataract or have had cataract surgery. Like many conditions that once were accepted as part of getting older, loss of vision due to cataracts can now be corrected in most cases. Cataract surgery is one of the most common and effective operations performed today. The surgeon removes the cloudy lens and replaces it with a clear intraocular lens that becomes part of the eye. About 90 percent of patients experience improved vision from the surgery.
Cataracts, which cloud the lens of the eye, are found in more than half of all Americans over the age of 65. Cataracts begin to form around age 55 for most of us, though they have been found in much younger people. It can take many years before you notice any symptoms, but each day your vision continues to worsen. No one really knows why cataracts form. But they are extremely common and should be examined by an eye care professional.
All of these warning signs can indicate other eye problems as well and should be checked by an eye care professional.

How are cataracts treated?
Cataract surgery is the most commonly performed surgery in all of medicine. Over 18 million cataract procedures are performed worldwide each year, including thousands performed at Drs. Campbell, Cunningham, Taylor & Haun.
Cataract microsurgery is performed on an outpatient basis at Eye Surgery Center of East Tennessee.
Advancements in cataract surgery allow physicians to perform the procedure with little discomfort. During a cataract surgery, our board-certified Ophthalmologists remove the affected natural lens of the eye with a small instrument and implant a replacement lens, or Intraocular Lens (IOL). This procedure restores the eye’s ability to allow light to pass through unobstructed to the retina. The procedure itself only takes a few minutes for most cases and no stitches are required.
Cataract surgeries are performed on one eye per surgery visit. Patients typically return home the same day and can resume normal daily activity within a day or two.
In addition to the standard lenses generally covered by Medicare, premium lens options are now available for an additional out-of-pocket expense. Multifocal lenses can help improve distance, intermediate, and near vision, even reducing your need for reading glasses, while toric lenses are specifically designed to correct degrees of astigmatism.
