4 Essential Cataract Facts Every Patient Should Know, from Park Ophthalmology

Many Triangle residents diagnosed with cataracts turn for guidance to Dr. Beth R. Friedland and Park Ophthalmology. Unfortunately, cataracts are a leading cause of vision loss among adults older than 40, and one of the main causes of blindness in the world. The good news is that most people diagnosed with cataracts can be treated successfully with surgery. Dr. Friedland has a specialized interest in ocular gerontology (treatment of the elderly) and she has decades of experience in eye surgery. Here are some basic facts that every cataract patient should know about the condition and its treatment.

Park Ophthalmology presents four fundamentals to help patients understand cataracts: 

  • Causes: A cataract is a clouding of the eye’s lens, caused by the breakdown of proteins. Aging is the primary cause, with 60 to 90 percent of those older than 65 affected. Circumstances that increase the risk for cataracts include smoking, heavy drinking, obesity, high blood pressure, previous eye injuries, family history, too much UV light (sun) exposure, diabetes and exposure to radiation from x-rays and cancer treatments.
  • Symptoms: Typical signs of cataracts include a fuzziness or cloudiness in vision, sensitivity to light or glare, seeing colors as washed out or faded and seeing halos around lights. A frequent need to change lens prescriptions could also be a sign of cataracts. An ophthalmologist will be able to diagnose cataracts during an exam while the eyes are dilated.
  • Treatments: Cataract surgery involves the removal of the clouded lens and replacement with an artificial lens. The surgery is an outpatient procedure during which the eye is numbed and the surgeon makes small incisions near the edge of the cornea to reach the lens. The patient will be awake during the procedure but will only notice light and movement, not the specifics of the surgery itself. The patient goes home the same day.
  • Outcomes: With a new artificial lens in place, patients experience much improved vision. Some patients notice improvement the day after surgery; others might have to wait two weeks to a month for clear vision to return. Occasionally, cloudy vision returns after a few months, but this is easily remedied with a laser procedure.

When a patient is affected by cataracts, don’t delay diagnosis and treatment. The sooner help is found, the quickly normal vision can return.
