HOW THE EYE WORKS
To have normal vision, the light must be focused precisely onto the retina in the back of the eye. This requires that both the cornea and the lens of the eye are clear and functioning correctly. When the lens becomes cloudy, it is called a cataract. This will reduce the amount of light and the clarity of the image entering the eye.
When do cataracts need to be removed?
A cataract is simply a clouding of the eyes natural lens. Cataracts do not harm the eye and in most cases, there is no such thing as leaving cataracts in too long. Very simply, cataracts need to be removed when they become bothersome. If the blurring of your vision is simply annoying, and you are still able to do the things you enjoy doing, you may wait a while for cataract surgery.
NOTE: If your doctor tells you that your cataract MUST be removed and you are not having noticeable problems with your vision it may be wise to get a second opinion.
How do we fix cataracts?
In cataract surgery, the cloudy lens is replaced with a synthetic clear lens implant. There are lens implants to correct nearsightedness, farsightedness and astigmatism. We also have multifocal lenses which can give some patients clear distance and up close vision without glasses.
