Q. What Is a Cataract?

My father has cataract in his eye, which interferes a lot with his vision. What is cataract?
A1A senile cataract (or clouding of the eye), occurring in the aged, is characterized by an initial opacity in the lens, subsequent swelling of the lens and final shrinkage with complete loss of transparency. This condition as an effect on ones vision, and it is important to treat it early, as it becomes harder to treat as time goes by, and may eventually lead to blindness in that eye.
A2A cataract is a clouding that develops in the lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. Early in the development of age-related cataract the power of the lens may be increased, causing near-sightedness (myopia), and the gradual yellowing and opacification of the lens may reduce the perception of blue colors. Cataracts typically progress slowly to cause vision loss and are potentially blinding if untreated, therefore it is important to see an Ophthalmologist as soon as possible. This situation is easily treated when done early.
A3A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye's focus, letting us see things clearly both up close and far away.

Q. What vitamin through diet shall I take to prevent cataract and how can I help my dad?

My father recently had a cataract surgery. This was his second cataract surgery. After this surgery I got scared as what’s going wrong with my dad and he had the cataract the second time. As per the doctor, my dad must be short in vitamins in his diet. He has been given some vitamin tablets. I know that cataract is genetic. I guess I may also have cataract in my old age. What vitamin through diet shall I take to prevent cataract and how can I help my dad?
AYes, vitamins if not taken in required amount through diet may lead to vitamin deficiency. As deficiency in vitamin E -an antioxidant and vitamin B1 and B2 can lead to cataract. You must take them in required amount. Foods which have vitamin E are all vegetable oil, green leafy vegetables and egg. Cereals and fish are good source for vitamin B1 and vitamin B2 is surplus in milk and dairy products; eggs, cereals and green leafy vegetables.

Q. I had cataract surgery with iol implant, and ever since I have awful light sensitivity. Any ideas?

I can't go into a "super store" without my sunglasses. My eyes ache at the end of the day. My doctor says "I don't know!"
AMay sound a bit silly question, but have you tried to consult your ophthalmologist (eye doctor, e.g. the one that performed the operation) about it? Cataract surgery, although considered very successful, isn't problem-free. Primary physician may not have the necessary specialization to deal with these subjects.
