Cataracts Explained

by: Optometrist Noosa on

As we age, cataracts become more common.

What are Cataracts?

Cataracts are a cloudiness that can form in the lens of the eye. Poor vision results because the cloudiness interferes with light entering the eye.

Most cataracts are age related, which means the older you get, the more likely you are to develop them. Cataracts may also be present at birth or acquired as a result of disease (such as diabetes), trauma to the eye, exposure to radiation or prolonged use of steroids.

Long-term exposure to ultra-violet light is thought to contribute to the development of cataracts.  If left untreated cataracts can cause blindness.

Signs of Cataracts

Usually cataracts affect both eyes but often develop at different rates in each eye. You may experience difficulty reading, recognising faces and watching television.

If the cataract is more advanced your lens may appear brown and/or white and your vision may appear as though you are looking through a mist or a fog. Generally an eye with a cataract becomes more sensitive to bright light and glare.

Cataracts Treatment 

For many people, cataracts won't require surgery. Cataracts may become a nuisance but often they develop to a certain level and then stabilise.

If you have a cataract that impairs your vision to a degree where it interferes with your everyday activities or your safety, the cataract-affected lens can be removed surgically and replaced with a clear artificial lens.

Before recommending cataract surgery your ProVision optometrist will consider several factors:

  • The condition of the eye
  • Your general health
  • Any complicating conditions such as glaucoma or diabetes
  • The expected improvement in vision after surgery

Today the removal of a cataract is a relatively simple and minor procedure. Often it is performed under a local anesthetic, and in most instances, does not require an overnight stay in hospital. Cataract surgery improves vision in more than 95% of cases.

If you haven't had your eyes checked recently or have any concerns or queries about Cataracts or any other eye health issues, Noosa Optical can assist you with our professional advice.
