CATARACT
What is a Cataract?
The human eye contains a lens, much like the lens of a camera. Its function is to focus light rays onto the retina, the sensitive membrane at the back of the eye, which transmits this image to the brain. This lens must remain clear for the light to pass through and reach the retina. When the lens becomes cloudy, it is called a cataract. In other words, the cataract is not a growth or a film over the eye. It is the natural lens of the eye that has become cloudy.
What are the Signs of a Cataract?
In the early stages of cataract development, vision is blurry with occasional fluctuations. Some patients become nearsighted or even experience an improvement in their farsightedness. This is due to changes within the lens that make it bend light slightly more than it used to do before. Dimming of vision increases with time.
What is the Treatment of a Cataract?
The treatment of a cataract is the surgical removal of the cloudy lens and replacing it with a clear plastic lens.
When Should a Cataract be Removed?
The time for a cataract surgery can vary with the degrees of impaired vision and how it handicaps the individual patient's lifestyle. Someone who leads an active life and relies a great deal on the eyes for reading or driving will need cataract removal at a much earlier stage than someone with less critical visual needs. The decision for surgery is made by the ophthalmologist in consultation with the patient. When cataracts are left in the eye long past the stage of blindness, they cause inflammation and some cases glaucoma. With our present methods of cataract removal, the operation can be performed at any stage of development with a high rate of success.
