What is cataract?

Cataract is clouding of the eye’s natural lens. It is a natural process of ageing. Every individual gets it sooner or later. Cataract impairs focusing of light on the retina and hence blurs vision.

What are the causes of cataract?

Old age is the most common cause of cataract. It also sometimes occurs relatively early in life due to factors such as injury, excessive sunlight. Toxic chemicals, changes in the body's metabolism, drugs or other eye diseases, such as glaucoma and inflammation. There can also be hereditary predisposition to earlier occurance of cataracts.

What are the types of cataract?

1. Senile Cataract (Due to old age)

2. Congenital Cataract (occurs by birth)

3. Traumatic Cataract (Due to eye injuries)

​4. Steroid Induced Cataract (side effects of drug)

What are the symptoms of cataract?

People with cataract. even when wearing glasses, typically have:

1. Glare at night

2. Difficulty in recognising colours

3. Foggy / smoky vision

4. Frequent changes in their glass prescription

What is the treatment for cataract?

There are no medicines with proven efficacy to prevent or to treat cataract. The only effective treatment is surgical removal of cataract. Diabetes, hypertension and other general health problems are not a contraindication for cataract surgery. The cataract need not 'mature' for surgery.


When is treatment advised?


The decision to treat a cataract is made together by the eye care practitioner and the patient. It is based on the degree to which the cataract is impairing vision and the effect of the impairment on the patient's quality of life.
