An eye can be compared to a camera. The light rays entering the eye are focused by the lens onto the retina. For light to pass through the eye and form an image on the retina, the lens must be clear. Cataract is the clouding of the eye’s normally transparent lens, preventing light from going through to the retina leading to hazy vision. Since the light rays no longer pass through the lens easily, the patient cannot see clearly and this condition is called CATARACT.

Symptoms of Cataract include:

  • Difficulty in performing simple day to day activities.
  • Painless, gradual, progressive blurring of vision.
  • Discomfort or inability to see in bright light.
  • Double or multiple images.
  • Colors appear dull.
  • Change in color of pupil of the eye to grey or white.
  • Poor night vision and
  • Need for frequent changes in spectacles.


Reasons of Cataract include:

Cataracts usually develop due to ageing; they can also form following any severe injury to the eye, or due to other problems like eye inflammation, eye tumors, glaucoma, iritis or general body disorders like diabetes and some times in young children and newborns. Some of the reasons thought to cause early cataracts are smoking, diabetes, excessive exposure to sunlight and excessive or indiscriminate use of certain drugs like corticosteroids.

Cataract cannot be prevented, delayed or stopped with medication. Surgery is the only cure. Cataracts are treated easily and inexpensively by surgery.

  • The surgery involves removing the cloudy lens and replacing it with a clear artificial lens called intraocular lens (IOL.) An IOL is a tiny transparent lens, inserted in the eye during surgery. Unlike contact lenses, an IOL stays permanently in the eye and does not cause irritation
  • Surgery is normally carried out under local anesthesia, except in the case of children.
  • It is a relatively bloodless operation and takes approximately 25-30 minutes.
  • It is in most cases, a day care surgery.
  • Surgery is stitchless with no requirement of sutures.
  • The success rate is an overwhelming 98%. The Cataract surgery is probably one of the most successful surgical interventions in the world today. However there are situations and circumstances that can change the outcome.
  • Glasses are usually required for perfect sight after surgery.
  • Lasers are used to clear the after cataract membrane which grows in about 35% of cases after cataract surgery. The development of the membrane depends on the quality of the IOL.

Phacoemulsification (Commonly called as Laser)

Recent techniques, such as phacoemulsification, enable the cloudy lens to be emulsified, (broken into small pieces) by means of ultrasound energy within the eye and removed by suction through a small incision of about 3mm. A foldable substitute lens is inserted through this small incision and usually no stitch is required. Post operative recovery is faster than conventional surgery by 3-4 weeks.

It is the ophthalmic surgeon who makes the final decision on whether the patient can undergo phaco or not.

Advantages of Phaco:

  • Early surgery can be done, so the patient need not wait for the Cataract to mature.
  • Small incision of only about 3mm. As the incision is small, it heals faster.
  • Wound heals without sutures. (No sutures so no suture-related problems like irritation and watering and no need for suture removal.)
  • Images are clear and of the same dimension without distortion.
  • Full vision returns very early.
  • Normal field of vision.
  • Early return to work
  • No need to continue eye drops for a long period of time.
  • No need for overnight stay, the patient is admitted in the hospital for a few hours only.
  • Only one post-operative visit is necessary.
  • Stable refraction after one month.

Our consultants are highly experienced in this procedure and the latest microscopes and phacoemulsification machines are available in the well-equipped operation theatre exclusively used for eye surgery.

Your counselor will advice you about cataract, pre-operative precautions, various types of lenses available in the market. You will be given a total estimate of the surgery for the various options available. Please bring to the notice of your counselor if you can avail of mediclaim at the onset of discussion.
