Cataract Surgery

A cataract is a painless, cloudy area in the lens of the eye that blocks the passage of light to the retina, which causes vision impairment. Cataracts sometimes may remain small and may not be noticeable. They may not seriously affect vision, and some cataracts do not need to be removed. However, many cataracts grow larger or more dense over time, often causing severe vision changes.

Globally cataracts are the leading cause of blindness, affecting 18 million people. Cataracts are even more significant as a cause of low vision affecting 62 million worldwide.

What Are the Symptoms of Cataracts?
Not all cataracts impair vision or affect daily living. But when they do, common symptoms include:
  • Cloudy, fuzzy, foggy or filmy vision.
  • Glare from lamps or the sun, which may be severe.
  • Difficulty driving at night due to glare from headlights.
  • Frequent changes in eyeglass prescription.
  • Double vision.
  • Second sight – temporary improvement in near vision (such as that needed for reading) in farsighted people.
  • Difficulty performing daily activities because of vision problems.
Who Do Cataracts Affect?
Aging and exposure to ultraviolet radiation can cause cataracts. People may also experience cataracts after an eye injury, as a result of eye disease, after the use of certain medications, or as a result of medical conditions such as diabetes.

Genetics may be another risk factor for developing cataracts. People with a family history are more likely to develop them. The color of your eye may also contribute to the development of cataracts. People with darker-colored irises appear to have an increased risk of developing them.

How Are Cataracts Treated?
Cataracts are usually treated with surgery if vision problems are interfering with the person's quality of life. Cataract surgery is very common and currently has the highest success rate of any surgical procedure. It involves removing the natural lens of the eye, which contains the cataract. The lens is then usually replaced with an artificial lens called an intraocular lens (IOL) implant.

"I have worn glasses since I was 5 years old and I could never wear contact lenses because I have an astigmatism and I just couldn't see properly if I wore contact lenses. Since Dr. Baker did my cataract surgery I don't have to wear glasses anymore, I've got perfect vision!" - Gayle
