IMPROVE YOUR QUALITY OF VISION
A cataract is a clouding of the lens of the eye; cataract surgery is performed to improve vision by replacing the clouded lens with an artificial one. Cataracts affect millions of people in the United States each year. Most cataracts are the result of aging, though some form as a result of genetic factors, disease or injury. Cataract surgery is common and considered safe and effective.
BENEFITS OF CATARACT SURGERY
Cataract surgery’s benefits are many, greatly enhancing the quality of life. They include the following:
- Improved quality of vision (sharper images, brighter colors)
- Less difficulty with routine tasks (particularly night driving)
- Decreased dependency on eyeglasses
- Greater independence, regardless of age or disability
- Greater safety
Research indicates that the improved vision provided by cataract surgery reduces the risk of falls, making exercise, sports, and hobbies safer. This, combined with the improved ability to read, recognize faces, and perform everyday activities with greater ease, results in improved physical health, increased sociability, and longer life expectancy.
THE CATARACT SURGERY PROCEDURE
After the pupil is dilated, and the area in and around the eye is numbed with anesthesia, a tiny incision is made to insert an ultrasonic probe. The probe emulsifies (breaks up) the cloudy lens into tiny pieces that are then suctioned out of the eye. Once the cloudy lens has been removed, an artificial lens is implanted.
The new lens, known as an intraocular lens (IOL), is often inserted through the original incision. Some varieties of IOLs serve multiple purposes, such as blocking ultraviolet light or working as bifocals. Depending on the type of IOL used, sutures may or may not be needed.
Surgery is usually performed on an outpatient basis in a doctor’s office, takes only 20 to 30 minutes, and is relatively painless. A very high percentage of patients demonstrates improved vision after the procedure.
CANDIDATES FOR CATARACT SURGERY
Cataracts caused by aging develop gradually, and patients may not notice the early vision changes they cause. It is only when their cataracts start interfering with a vision that patients may become aware of them. An ophthalmologic examination will detect cataracts, and rule out other causes for vision issues, such as glaucoma or macular degeneration. Patients who become aware of visual difficulties related to cataracts usually experience, especially at night, clouded, blurred or dim vision.
