Overview
A cataract is a clouding of the lens of the eye, which is ordinarily clear. Seeing through hazy lenses is similar to looking through a frosty or fogged-up window for persons with cataracts. Cataracts can makes it hard to read, drive a car (especially at night), or notice the expression on a friend’s face due to clouded vision.
The majority of cataracts form slowly and do not affect your vision at first. Cataracts, on the other hand, will obstruct your vision over time.
Cataracts can cause the following signs and symptoms:
- Vision that is clouded, hazy, or dull
- Night vision becomes more difficult
- Sensitivity to light and brightness
- For reading and other tasks, a brighter light is required.
- Changes in eyeglass or contact lens prescriptions on a regular basis
- Color fading or yellowing
The most common cause of cataracts is a change in the tissue that makes up the lens of the eye due to ageing or injury. The lens’ proteins and fibres begin to break down, giving blurry or unclear vision.
Cataracts can be exacerbated by inherited genetic abnormalities that cause other health issues. Other eye diseases, previous eye surgery, or other conditions such as diabetes can all induce cataracts. Long-term usage of steroid medicines can also lead to cataracts.
Cataract surgery is fundamentally surgical, and the timing is determined by the patient’s visual requirements. Only if a cataract is obstructing one’s eyesight to the point where it is interfering with daily activities should it be removed. That decision is made by the patient himself. If you have cataracts in both eyes, the operations should be done one month apart (unless there is any emergency).
Make an appointment with your neurosurgeon, if you have persistent signs and symptoms that concern you.

FAQ’S
The lens, in conjunction with the cornea, helps focus light onto the retina. The retina is the light-sensitive layer of the eye that transmits visual information to the brain. The lens is positioned right behind the iris, which is the colored component of the eye (brown, blue, or green). The lens changes shape during focusing (accommodation). When you gaze at nearby objects, it gets more convex (curved), and when you look at distant objects, it becomes flatter.
Cataract surgery is now one of the most popular procedures performed in India. It’s also one of the most effective and safe. More than 90% of persons who have cataract surgery report improved eyesight as a result of the procedure.
The most recommended form of cataract surgery, phacoemulsification with a foldable intraocular lens implantation through a 3 mm incision, provides excellent results all around the world. Other procedures are only carried out in exceptional conditions.
- Congenital cataract
- Secondary cataract
- Traumatic cataract
It is a day care procedure so the patient need not to stay in hospital, once the surgery and medications is done. The patient can leave on the same day itself.
