Few common FAQs’ about Cataract
What is Cataract?
It is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night.
How a cataract forms?
- The lens, where cataracts form, is positioned behind the colored part of your eye (iris). The lens focuses light that passes into your eye, producing clear, sharp images on the retina — the light-sensitive membrane in the eye that functions like the film in a camera.
- As you age, the lenses in your eyes become less flexible, less transparent and thicker. Age-related and other medical conditions cause tissues within the lens to break down and clump together, clouding small areas within the lens.
- As the cataract continues to develop, the clouding becomes denser and involves a bigger part of the lens. A cataract scatters and blocks the light as it passes through the lens, preventing a sharply defined image from reaching your retina. As a result, your vision becomes blurred.
- Cataracts generally develop in both eyes, but not evenly. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.
What are the symptoms of a developing 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.
When a patient can undergo a cataract surgery?
Cataract surgery can be performed as soon as the patient feels handicapped in performing routine activities at work and leisure. It is not advisable to wait for the cataract to mature as unnecessary delay can make surgery difficult and prone to complications. Modern cataract surgery can be performed successfully in any season.
- There is no need for bed rest after surgery.
- One can walk, eat normally, watch TV and be normal around home on the day of the surgery.
- One needs some protective glasses only when outdoors.

Benefits for cataract surgery
Benefits of cataract surgery has many in numbers which is cannot be measured statistically. These include: –
- Improved colour vision – colours are brighter and more vivid
- Greater clarity of vision – vision is crisper and sharper
- Improved quality of life – studies have repeatedly shown that people enjoy an improved quality of life after successful cataract surgery. Many people can resume driving, reading, writing, watching television, sewing, household work and using a computer immediately after. Even when retinal diseases or other problems prevent a total restoration of vision, the remaining vision is usually improved by cataract surgery.
