Cataract is not a problem as it once was. For most people with poor vision from cataract, the prospects of regaining good vision and resuming normal daily activities are excellent. Our facility is oriented towards providing low-stress patient-friendly care.
A cataract is a clouding of the normally clear lens of your eye. Looking through a cloudy lens is like trying to see through a frosty or fogged-up window. Clouded vision can make it more difficult to read, drive a car — especially at night — or see the expression on a friend's face. Cataracts commonly affect distance vision and cause problems with glare. They generally don't cause irritation or pain.
A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and producing clear, sharp images. The lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, the cells accumulate causing the lens to cloud, making images look blurred or fuzzy. For most people, cataracts are a natural result of aging.
Causes
Cataracts are degenerative changes in the structure of the eye that form when protein in the lens begins to clump together, clouding a small area of the eye. This cloud will continue to grow and interfere with vision. They can occur in one or both eyes. While the most common cause of cataracts is age, they can also be caused by eye trauma, certain medications, and various environmental and lifestyle factors. Additionally, some cataracts are congenital. Learn more about the cataracts and what causes them.
As people grow older, there can be changes to the protein that makes up the lens in the eye. Some experts think that this may be linked to how fluids and nutrients reach the eye. These changes in the lens protein can lead to cloudy areas developing. It is not known how, or why, getting older causes these changes to happen.
Symptoms
Having cataracts is often compared to looking through a foggy windshield of a car or through the dirty lens of a camera. Cataracts may cause a variety of complaints and visual changes, including blurred vision, difficulty with glare (often with bright sun or automobile headlights while driving at night), dulled color vision, increased nearsightedness accompanied by frequent changes in eyeglass prescription, and occasionally double vision in one eye.
Treatment
During the diagnostic examination, an ophthalmologist will carefully measure the shape, size and general health of the eye to determine whether a lens implant will be effective. In the relatively small number of cases where it won't be, eye-glasses or contact lenses will improve vision after traditional cataract surgery. Glasses, while used for years, have drawbacks. Their extreme thickness makes them unattractive and heavy. Magnification and distortion of the visual image causes objects to appear closer and 25 percent larger than they are. Peripheral vision may be reduced. Contact lenses provide fairly good vision, but many elderly people have trouble inserting, removing and cleaning them.
If you have cataracts, you may find that your vision is still good enough for you to get along fine with glasses or contact lenses and that surgery isn't required. The time to consider treatment is if your vision has become noticeably worse, can't be corrected with a change in your prescription lenses and this is interfering with your everyday activities such as work and hobbies.
