Early onset of cataract can be prevented

Nearly everyone knows that cataracts are the effect of the normal process of aging. However, it is an equally important fact that cataracts occur early in the Indian population. And, yes, early onset can be prevented or delayed.

P.Kanthamani of Krishna Eye and ENT Hospital, explains that a cataract occurs when the transparent lens (similar to the lens of a camera which enables vision) becomes opaque. The most common cataract is senile cataract – that occurs with age, but it is now occurring at an earlier age, she says. By blocking the source of light that enters the eye, it will cause cloudy or foggy vision and glare.

Once cataract sets in, the prevailing medical prudence is to operate immediately and not wait for it to ripen, especially when it occurs earlier in patients, she explains. The surgery, which lasts for ten minutes, is not performed on both eyes at the same time, Dr. Kanthamani says.

Some of the risk factors include excessive exposure to UV rays (from sunlight), lack of adequate nutrition and uncontrolled diabetes and hypertension, doctors point out.

The average age of the person with cataract in America is over 70 years, however, in India we are seeing people in the 50's, Amar Agarwal of Dr. Agarwal's Eye Hospital says. “One reason of course is that we have more of sunlight and the U/V rays are harmful to the eyes. Using sunglasses with adequate U/V protection will help delay onset.”

Uncontrolled blood sugar and blood pressure will also lead to early onset of cataract; and facilitates faster maturity. “If you do not control your BP or sugar, the metabolism of the eye is going to be defective, and will lead to a variety of problems, including cataract. Also, the diabetic cataract is sticky and tougher to remove,” Dr. Amar says. Taking steroids over a long period is known to cause cataracts. Do not self medicate; take steroids only under strict medical supervision, both ophthalmologists warn.

On the other hand, eating vegetables, and fruits, exercising regularly to keep obesity at bay are all good for visual health. “There is no point starting at 50 years. You cannot win the game this way. It has to be part of your lifestyle,” Dr. Amar adds.
