Cataracts Q & A

James N. Cohn M.D. & Associates

What are cataracts?

Inside your eyes, you have natural lenses that bend light rays to help you see. Cataracts occur when these lenses cloud over and affect your vision. This clouding results from protein clumping together. Over time, cataracts grow larger and cloud more of your lens, making it harder for you to see. Some cataracts result in color distortion.

There are three types of cataracts named for their location. They are:

  • Nuclear -- located in the center of your lens and changes color from clear to yellow or brown
  • Cortical -- affect the layer of your lens surrounding the nucleus and looks like a wedge or spoke
  • Posterior capsular -- found in the back outer layer of your lens

What symptoms are associated with cataracts?

The most common symptoms of cataracts include:

  • Hazy vision
  • Gradual change in the amount of color tinting seen
  • Lighting becomes too bright
  • Halos appear around lights
  • Reduced night vision
  • Increases in the frequency of prescription changes in your eyeglasses or contact lenses

How are cataracts diagnosed?

A diagnosis of cataracts from one of the doctors at James N. Cohn M.D. & Associates comes after a review of your medical and family history, as well as your symptoms. Additionally, you will undergo several tests, including:

  • Visual acuity test: A visual acuity test requires you to read a series of letters that gradually decrease in size. Visual acuity tests each eye separately to identify signs of vision impairment.
  • Slit-lamp examination: Slit lamps magnify your eye and allow the doctors at James N. Cohn M.D. & Associates to see your cornea, iris, lens, and the space between your iris and cornea and make it easier to detect any tiny abnormalities.
  • Retinal exam: Retinal exams require pupil dilation to make it easier to examine the back of your eyes for signs of cataracts.

How are cataracts treated?

While new eyeglasses, brighter lighting, anti-glare sunglasses, and magnifying lenses are all short-term fixes for cataracts, the only long-term treatment is surgery.  Cataract surgery requires Dr. Cohn to remove your clouded lens and replace it with an artificial lens. Referred to as an intraocular lens, it gets positioned in the same place as your natural lens and becomes a permanent part of your eye.
