What is a cataract?

A cataract is an eye disease in which the clear lens of the eye becomes cloudy or opaque, causing a decrease in vision. Although the word cataract to describe this condition has been part of the English language only since the middle of the 16th century, the eye disease has been recognized and surgically treated since ancient times.

What are the symptoms of cataracts?

Cataracts often affect both eyes, but rarely equally. People with cataracts may have the following symptoms:

  • Blurry, cloudy, or misty vision.
  • Some describe it as similar to looking through frosted glass.
  • Vision may be affected by small spots or dots.
  • The patient sees small patches which blur parts of his/her field of vision.
  • Vision gets worse when lights are dim.
  • Vision is sometimes worse when light is very bright (glare).
  • Some people with cataracts also comment that colors appear less clear and faded.
  • Reading becomes very difficult, and eventually impossible.
  • Glasses need to be changed more frequently.
  • Eventually wearing glasses becomes less effective.
  • In some rare cases patients can see a halo around bright objects, such as car headlights or street lights.
  • Double vision in one eye (rare).

What are the treatment options available for Cataract?

If the patient is found to be only mildly affected surgical treatment may not be needed. During its early stages, stronger glasses and brighter lights may help improve vision. The following simple approaches may assist people who are not ready yet to have surgery:

  • Make sure your glasses are the most accurate prescription possible.
  • Use a magnifying glass for reading.
  • Get brighter lamps for your house. Halogen lights may help a lot.
  • Wear sunglasses to reduce glare on sunny days.
  • Try to refrain from driving at night.

Cataract Surgery is amongst the most commonly performed surgeries all over the world. Billions of patients have been operated till date. In the traditional methods, cataract surgery required a cut in the eye 10-12mm wide which required stitches. Now a day 1.8 to 2.2mm incision made in cataract surgery so does not required stitches. At Karnavati Eye Hospital have specialists for below treatments :


  • In most cases this surgery can be performed without giving any painful injections around the eye. Anesthesia is achieved by using eye drops only.
  • Very small incision of 1.8 to 2.8mm which is suture-less
  • This surgery also minimizes the need for spectacles after surgery due to lesser induced cylindrical power.
  • The procedure is safe and is ideal for diabetic patients. It can be performed in any season.
  • The visual recovery often starts within a few minutes and is complete in a day or two as compared to traditional surgery where the total visual recovery is achieved in 6-8 weeks.
  • This is called a “WALK IN WALK OUT” surgery. The patient can go back home on the same day of surgery and can resume most of the daily activities like watching TV, bathing driving, cooking etc. without any significant restrictions. The patient can start work from the third post-operative day.

Which lens option is right for you?

  • Before surgery your eyes are measured to determine your IOL prescription, and you and your Eye M.D. will compare options to decide which IOL type is best for you, depending in part on how you feel about wearing glasses for reading and near vision.
  • The type of IOL implanted will affect how you see when not wearing eyeglasses. Glasses may still be needed by some people for some activities.
  • If you have astigmatism, your Eye Specialist / Doctor will discuss toric IOLs and related treatment options with you.
  • In certain cases, cost may be a deciding factor for you if you have the option of selecting special premium lOLs that may reduce your need for glasses.
