Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear. But if you have cataracts, the lens will cloud. It is similar to looking through a fogged or dusty windshield.
With cataracts, things can look fuzzy, cloudy or less colorful.
Most age-related cataracts develop gradually. As a result, you may not notice signs or changes in your vision right away when cataracts first develop.
Here are some vision changes you may notice if you have a cataract:
Having blurry vision
Seeing double (when you see two images instead of one)
Being extra sensitive to light
Having trouble seeing well at night, or needing more light when you read
Seeing bright colors as faded or yellow instead
Cataracts can be removed only with surgery.
If your cataract symptoms are not bothering you very much, you don’t have to remove a cataract. You might just need a new eyeglass prescription to help you see better. You should consider surgery when cataracts keep you from doing things you want or need to do.
The procedure to extract the opacified cristalline (cataract) using ultrasonic energy is called phacoemulsification. This is done through a minimum opening. In this way the patient's recovery is immediate. It is what we call minimally invasive surgery.
During cataract surgery, your cloudy natural lens is removed and replaced with a clear artificial lens. That lens is called an intraocular lens (IOL). Your ophthalmologist will talk with you about IOLs and how they work.
