Cataract

What is Cataract?

  • A cataract is a clouding of the normally clear lens of your eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend’s face.
  • Most cataracts develop slowly and don’t disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision.
  • At first, stronger lighting and eyeglasses can help you deal with cataracts. But if impaired vision interferes with your usual activities, you might need cataract surgery. Fortunately, cataract surgery is generally a safe, effective procedure.

How is Cataract Caused?

  • Most cataracts develop when aging or injury changes the tissue that makes up your eye’s lens.
  • Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes. Long-term use of steroid medications, too, can cause cataracts to develop.

Who is at Risk Cataract?

Factors that increase your risk of cataracts include:

  • Increasing age
  • Diabetes
  • Excessive exposure to sunlight
  • Smoking
  • Obesity
  • High blood pressure
  • Previous eye injury or inflammation
  • Previous eye surgery
  • Prolonged use of corticosteroid medications
  • Drinking excessive amounts of alcohol

What are the signs and symptoms of Cataract?

Signs and symptoms of cataracts include:

  • Clouded, blurred or dim vision
  • Increasing difficulty with vision at night
  • Sensitivity to light and glare
  • Need for brighter light for reading and other activities
  • Seeing “halos” around lights
  • Frequent changes in eyeglass or contact lens prescription
  • Fading or yellowing of colours
  • Double vision in a single eye

At first, the cloudiness in your vision caused by a cataract may affect only a small part of the eye’s lens and you may be unaware of any vision loss. As the cataract grows larger, it clouds more of your lens and distorts the light passing through the lens. This may lead to more noticeable symptoms.

Why do I need a Lens Implant after Cataract Surgery?

Without lens being implanted back into your eye, you would not be able to see clearly. This is because our natural crystalline lens possess its own refractive power which helps us to see clear. So after removing the lens diagnosed with cataract, we have to replace it with a new artificial lens in order to help you to see clear.

What kind of the treatment & benefit for Cataract

Only treatment is surgery. With the current technology, these days surgical technique has a very high recovery rate, provided if you apply eye drops regularly in the given time and follow our postoperative guidance.
