Are cataract causes always age-related?

What Causes a Cataract?

cataract causesAs your eyes age, they may become less able to process light and reflect sharp images because the lens has gradually become cloudy – this is called a cataract. The vast majority of cataract sufferers have developed this condition as they have grown older, making age one of the primary cataract causes. As a matter of fact, nearly half of all Americans over the age of 80 have cataracts (called “senile cataracts”) or have already had surgery to correct them.

In addition to advancing age, other cataract causes include:

  • Long-term exposure to ultraviolet light
  • Long-term and short-term exposure to radiation
  • Consequential effects of diseases such as diabetes and hypertension
  • Eye trauma or eye injury
  • Congenital conditions (present at birth, passed on through DNA)
  • Prolonged use of corticosteroids

Allergic or atopic conditions of the eye can also speed up the onset of cataracts, particularly in people who are predisposed to this condition. These are common cataract causes in children and young people.

A study of Icelandair pilots shows that commercial airline pilots are three times as likely to develop cataracts than other professions which do not involve flying. Excessive exposure to radiation coming from outer space may be another of the chief cataract causes.

Additionally, any jobs that expose workers to an unusually high amount of infrared radiation, such as in the glassblowing industry, are also susceptible to high levels of cataracts. This is called “exfoliation syndrome.” Exposure to microwave radiation is another example of cataract causes, so industries that involve close contact with satellite transmission equipment, radar equipment, radio wave transmitters and other similar machinery can also be more disposed to cataract development over time.
 

What Happens to the Lens When a Cataract is Present?

cataract-blurred-vision-new-yorkCataracts are the result of a change in the structure of lens protein. This change causes the lens to cloud over and become foggy in appearance. When clouding occurs on the lens, it cannot transfer clear images to the retina of the eye. The retina acts like the film in a camera, instantly developing the images that are passed through the lens. If cataracts are present, these images cannot be developed properly.

Crystalens Advantage

Crystalens Advantage

Crystalens is an increasingly popular choice in IOLs. It mimics the functioning of our natural young lens with a special design that allows the lens to flex along with your eye muscles (accommodation). This allows your eye to focus naturally for near, intermediate and distance vision. Crystalens is the only FDA-approved accommodating intraocular lens.

The ReSTOR Lens

The ReSTOR Lens

ReSTOR IOL is a very popular option that allows patients to see objects both near and far. The lens uses a special technology to distribute light. As a result, many patients do not have to wear glasses for all distances. Also, many patients who have a problem with accommodation choose to replace their natural lenses with ReSTOR for vision correction, even without having a cataract (e.g., presbyopia).

The lens distributes light over those multiple zones to produce a full range of vision correction. The ReZoom lens also offers clear vision in variable lighting conditions.
