Faq about cataract


Cataracts are a normal part of life, and will happen to almost everyone at some stage. In fact, by the time people reach 65 years of age, 90% will have developed cataracts. By the age 75, their cataracts can really affect their vision.

A cataract is a cloudy area that appears within the lens of the eye that affects vision, and occurs as a natural part of aging.

A healthy lens is clear, but as a cataract develops, the lens of the eye gradually becomes hard and cloudy, allowing less light to pass through and making it more difficult to see.

As the body ages, the lens of the eye, which consists of water and protein, can become cloudy due to protein clumping together, scattering the light landing on the retina and causing visual impairment. When the cataract blocks light, vision is disrupted.

A cataract can develop in one or both eyes, but is independent and cannot spread from one eye to another.

Currently, there is no medical treatment to reverse or prevent the development of cataracts. Once they form, there is only one way to achieve clear vision again, and that is to physically remove the cataract or cloudy lens inside the eye and replace it with an artificial intraocular lens (IOL).


Patients undergoing cataract surgery often have questions about the procedure and what will happen afterwards. Below are a few commonly asked question about what to expect

There’s no real way to prevent cataracts, as they are simply a part of aging and are caused by a natural buildup of protein in your eye’s lens. Fortunately, they can be treated with a common and generally safe surgery.

Mature or advanced cataracts means that your cataracts have developed to the point that your lens appears to be mostly opaque and makes things difficult to see. When you have mature or advanced cataracts you will usually require surgery.

People start to develop cataracts as early in their 40s, but generally don’t start to notice symptoms of their cataracts until their 60s.

No, but you can manage some of the early symptoms of cataracts with new prescription glasses or contact lenses, and by wearing sunglasses to counteract light sensitivity until it’s time to have surgery.

Usually, you only need to have cataract surgery when your cataracts start to affect your everyday vision. If you’re having trouble reading, watching TV, or driving, it’s time to talk to your eye care provider about next steps.

Modern cataract surgery is performed as day case surgery and takes 20-25 minutes.

Your eye may feel a little sore after surgery. Some patients feel no discomfort at all. Cataract surgery is not a painful operation and most patients will not experience any major discomfort.

The day after your cataract surgery most patients will be able to return to all normal activities except swimming.

In a minority of cases (perhaps 20 to 30 percent), months or years after cataract surgery, the posterior portion of the lens capsule that is left inside the eye during surgery for safety reasons becomes hazy, causing vision to again become blurred.

This „secondary cataract” (also called posterior capsular opacification) usually can be easily treated with a less invasive follow-up procedure called a YAG laser capsulotomy. In most cases, this 15-minute procedure effectively restores clear vision.

Mascara and makeup around the eyes should be avoided for a 10 days after cataract surgery. It may be advisable use disposable mascara brushes or even start with a new bottle of mascara to avoid risk of infection.
