Cataract
A cataract is the clouding of the transparent lens, which is located inside the eye. Cataract causes blindness, which is treatable.
What are the symptoms associated with Cataract?
- The vision usually becomes reduced or blurred.
- There is worsening of the vision or eyesight.
- There are frequent changes in the number for spectacles.
- The pupil appears whitish.
What causes Cataract?
Cataract is usually caused by the aging process. It can also develop in young people due to injury or illness. Sometimes it may be present at birth. Toxic drugs, acute diarrhea, diabetes, infection, injury and dietary deficiencies can also cause cataract.
What is the treatment available for this condition?
The only treatment for cataract is surgery, where the clouded lens is removed and replaced by an artificial lens. Spectacles may also be prescribed. An intraocular lens (IOL) is the best choice.
Should I take any preventive measures?
- In children cataract formation can be minimized by awareness of risks and taking precautions for safety of the eyes.
- Industrial workers should use protective goggles.
- Protect eyes from excessive exposure to sunrays, X-rays and intense heat.
- Quit smoking.
- Prompt medical and surgical treatment of eye injuries can prevent secondary cataract.
- Eat foods rich in proteins and vitamins, such as liver, eggs, milk products, carrots, cabbage and yeast.
Outcome
A cataract operation done by inserting an intraocular lens offers good chances of visual recovery. After surgery glasses may be prescribed for better vision.
If a cataract is not operated upon the vision will continue to deteriorate gradually. There is a misconception that the cataract should mature before it can be operated upon. This could be dangerous because a mature cataract may burst within the eye. An excessively ripe cataract can lead to complications such as glaucoma.
Cataract can lead to blindness. Do not wait. Have an operation as early as possible.
