What is a Cataract?

A cataract is a clouding of the natural lens inside of the eye.  Some level of cataract will develop in all of us as we grow older.  At first, a developing cataract may have little or no impact on one’s daily activities.

As a cataract progresses, patients may begin to notice some of the following:

  • Blurred Vision

  • Rings or halos around point sources of light

  • Difficulty seeing in dim light

  • Glare from oncoming headlights while driving at night

  • Decreased perception of color

Initial cataract treatment may include close observation or even simply changing glasses.

Doctors recommend cataract surgery for patients who feel that their vision has decreased to a level where they are unable to comfortably perform normal daily activities.  Examples may include:

  • Diminished ability to read, sew, or knit

  • Inability to see television clearly

  • More difficulty reading signs while driving

  • Patients may limit or stop driving at night due to glare from oncoming traffic

Cary, Chapel Hill Cataracts and Cataract Surgeons

Cataract surgery is one of the most commonly performed procedures in the United States.  It is a quick, painless procedure that involves the use of specialized equipment to remove the patient’s cloudy lens and replace it with a new clear lens made of synthetic material.

The goal of cataract surgery is to provide clear vision.  Most patients see more clearly one day after surgery and are back to their normal daily activities within three to four days.Advances in technology provide doctors with the capability to customize cataract surgery to meet the needs of each individual patient. Some patients choose advanced technology lenses which can eliminate the need for glasses after surgery.

Potential lens options include:

Standard Monofocal Lens
  • This type of lens will yield clear vision

  • Patients still require glasses (either for reading or bifocal)

Toric Lens

  • This is a special lens which neutralizes astigmatism and offers clear distance vision.

Presbyopia Correcting Lenses

  • Multifocal or accommodative lenses that provide distance and near vision without glasses

  • May be suitable for patients with astigmatism

While cataracts are the most common cause of decreased vision in our aging population, there are other eye disorders which can cause visual dysfunction.  If you are experiencing decreased vision, schedule a comprehensive eye examination to rule out other treatable causes.
