Cataract
Common symptoms are
- Blurry vision
- Colors that seem faded
- Glare
- Not being able to see well at night
- Double vision
- Frequent prescription changes in your eyewear
Cataracts usually develop slowly. New glasses, brighter lighting, anti-glare sunglasses or magnifying lenses can help at first. Surgery is also an option. It involves removing the cloudy lens and replacing it with an artificial lens. Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataracts.[2]
Cataract removal can be performed at any stage in the progression of the disease and no longer requires ripening of the lens. Surgery is usually performed without a hospital stay using local anesthesia. About 9 of 10 patients can achieve a corrected vision of 20/40 or better after surgery.[3] While cataracts do not cause astigmatism, custom designed lenses can be implanted to both replace the cataract and correct the patient's astigmatism.
