Cataracts are the leading cause of visual impairment in the world today.

Aging is the most common cause. A cataract is a progressive, painless clouding of the lens inside the eye. Cataracts block light, making it difficult to see clearly. Over an extended period of time, cataracts can cause blindness. They are often related to growing older, but sometimes they can develop in younger people.

The exact cause of cataracts is unknown. While the risk grows as you get older, these factors may also contribute:

  • Genetics: having parents, brothers, sisters, or other family members who have cataracts
  • Certain medical problems, such as diabetes
  • Smoking
  • Excess alcohol use
  • An eye injury, eye surgery, or radiation treatments on your upper body
  • Having spent a lot of time in the sun, especially while not wearing sunglasses with ultraviolet (UV) protection.
  • Some medications such as corticosteroids and insulin may cause the early formation of cataracts.

Most age-related cataracts develop gradually. Other cataracts can develop more quickly, such as those that occur in younger people or in people with diabetes. Doctors cannot predict how quickly a person’s cataract will develop.

What is the solution if you get cataracts?

If you have vision loss caused by cataracts, that cannot be corrected with glasses, you may need surgery to remove the cataract.

Cataract surgery in Lansing is done on an outpatient basis. The cloudy lens is removed and replaced with an artificial lens (IOL). The surgeon extracts the cataract by making an opening (incision) in the outer layer of the lens. S/he then uses high-frequency sound waves to break up and remove the cataract, leaving behind the posterior capsular bag into which they insert the new, clear IOL.

While complications from cataract surgery are rare, the most common are bleeding, infection, and changes in eye pressure, which are all treatable when caught early. Cataract surgery may also slightly raise the risk of retinal detachment.

Can Cataracts come back after surgery?

Sometimes, a side effect of cataract surgery triggers the return of cataract symptoms. This side effect is called posterior capsule opacification. Otherwise known as a “Secondary Cataract”. “Secondary cataracts affect about a third of people who have cataract surgery”. says Dr. David Bosak, “It is one of the reasons we have people return for follow-ups.”

Sometimes a few cells (too small to be seen during surgery) remain attached to the capsular bag. “In some people, the cells then cause scar-like tissue to develop on the capsular bag, behind the new artificial lens (IOL),” Dr. Bosak explains. “As the cells grow, they create a very thin cloudy film, which then affects your vision.”

Why does the film on the capsular bag make it hard to see clearly? Just like the cloudy lens did before surgery, a secondary cataract blocks some light from reaching the retina.

The good news is there is a simple, painless fix for secondary cataracts. It is an in-office procedure called a YAG laser capsulotomy. It requires no anesthetic — just some drops to numb your eye and dilate your pupil. The procedure is quick — just a couple of minutes — and recovery is fast, as well. “Typically, your vision improves in a day or two.” Dr. Bosak adds.

Antioxidants key to lowering risk of age-related cataracts

A $5.7 billion global medical bill to restore sight for the estimated 45 million people with cataracts could be slashed in half by a diet rich in colorful fruits and vegetables, according to an international study.

Researchers from China and the University of South Australia have published the first study of its kind to verify the link between foods high in antioxidants and a lower risk of age-related cataracts (ARC).

UniSA Senior Research Fellow Dr. Ming Li and colleagues from Xi’an Jiaotong University analyzed 20 studies from around the world looking at the impact of vitamins and carotenoids on cataract risk.

Despite some inconsistencies, the findings overwhelmingly support the benefits of eating citrus fruits, capsicum, carrots, tomatoes and dark green vegetables such as spinach, broccoli and kale to delay the onset of ARC.

Their paper has been published in the American Journal of Clinical Nutrition ahead of World Optometry Week (March 26-30).

“Age-related cataracts are the leading cause of visual impairment among the elderly throughout the world, with unoperated cataracts contributing to 35 percent of all blindness,” Dr. Li says. “Although cataract extraction surgery is an effective method to restore vision, it will have cost society more than $5.7 billion by 2020.”

With the population aging dramatically and an increasing number of people needing surgery, urgent action is needed, the researchers say.

“If we could delay the onset of ARC by 10 years it could halve the number of people requiring surgery.”

Improvements would rely on global changes to most of the world’s diet, however, with current consumption of antioxidants well below the recommended level to prevent age-related cataracts.
