Below is a list of Frequently Asked Questions for Cataracts:
What is a cataract?
A cataract is a clouding of the eye’s lens, which can lead to vision problems. The most common type of cataract is related to aging. More than half of all Americans over the age of 65 will have a cataract.
What are the symptoms?
The most common symptoms of a cataract are:
- Cloudy or blurry vision.
- Problems with light, such as headlights that seem too bright, glare from lamps or very bright sunlight.
- Colors that seem faded.
- Poor night vision.
- Double or multiple vision.
- Frequent changes in glasses or contact lenses.
How is a cataract detected?
Cataracts are detected during a comprehensive annual eye examination. The exam includes: a visual acuity test, to measure the ability to see at various distances; pupil dilation, to allow the eye care professional to examine the lens and retina; and, tonometry, a test to measure fluid pressure in the eye.
How is a cataract treated?
In the early stages of a cataract, vision may be improved with glasses, magnifying lenses or stronger lighting. If these measures do not help, surgery is recommended.
What happens during the surgery?
Cataract surgery is a same-day procedure which takes only about ten to twenty minutes. The patient is given an intravenous sedative and a topical anesthetic. The surgical procedure involves removing the natural lens, which has become cloudy, and replacing it with an intraocular lens (IOL) implant.
What about follow-up care?
Patients are seen in clinic one day following cataract surgery. The next post-operative visit usually occurs two to four weeks after the post-operative visit.
When will vision return after surgery?
Most patients can resume daily activities almost immediately; however, vision may be blurry. The eye needs time to heal and adjust so that it can focus properly with the other eye. Follow-up visits to the clinic are scheduled to evaluate progress.
Is cataract surgery effective?
Cataract surgery is one of the most common, safest and effective surgical procedures performed in the U.S. today. In over 90 percent of cases, patients who have cataract surgery experience better vision.
