Catract

What is catract?

A cataract is a clouding of the lens inside the eye which leads to a decrease in vision. It is the most common cause of blindness and is conventionally treated with surgery. Visual loss occurs because opacification of the lens obstructs light from passing and being focused on to the retina at the back of the eye.

It is most commonly due to aging, but there are many other causes. Over time, yellow-brown pigment is deposited in the lens and this, together with disruption of the lens fibers, reduces the transmission of light and leads to visual problems.

Those with cataracts often experience difficulty in appreciating colors and changes in contrast, driving, reading, recognizing faces, and coping with glare from bright lights.

Symptoms of catract

  • Cloudy vision.
  • Progressive nearsightedness in older people often called "second sight" because they may no longer need reading glasses.
  • Changes in the way you see color because the discolored lens acts as a filter.
  • Problems driving at night such as glare from oncoming headlights.
  • Problems with glare during the day.
  • Double vision
  • Sudden changes in glasses prescription.

How is a cataract detected?

If you notice any of the symptoms described previously, go to have an eye exam. By performing it, the Ophthalmologist will know if you have a cataract. Your eye doctor will perform a thorough examination of your eyes. Glare testing and contrast sensitivity tests are sometimes used. There is no single objective test to determine a need for cataract surgery. The final decision for cataract surgery is made by the patient and depends on how much the decreased vision from the cataract is bothersome.

How can a Cataract be treated?

At first, a change in your eyeglass change of glasses may be all that is needed. This may improve your vision temporarily. There are no medications or eye drops that will cause cataracts to disappear. When you are unable to do the things you like doing, or you are unable to pass your drivers license exam, cataract surgery should be considered.

In other words, think about surgery when your cataracts have progressed enough to affect your lifestyle. Whenever you feel your visual disturbance because of cataract is not allowing you to carry about your professional & personal work to your satisfaction it is at that stage when surgery should be considered.

Cataract surgery is very successful in restoring vision. Nine out of 10 people who have cataract surgery regain very good vision, somewhere between 20/20 and 20/40. Cataracts can only be removed with surgery
