What causes a cataract?
Though cataracts can occur at any age, most cataracts develop when aging or trauma cause proteins within the lens to break down and become cloudy or opaque. Less often, cataracts develop before birth, by use of corticosteroids, or by an inherited disorder. Prolonged exposure to sunlight and smoking may contribute to cataracts.
Can cataracts be prevented?
Though there is no certain prevention known, there are possible steps that a person could take in attempts to help prevent them. Wearing protective eyewear, when active, can aid against trauma. Wearing 100% UV protective sunglasses can aid against sun exposure. Avoiding smoking can aid in avoiding cellular oxidization.
Is anesthesia used for cataract surgery?
The eye is thoroughly numbed using a topical eye drop anesthetic and patients receive mild IV sedation, to ensure a comfortable surgical experience. General anesthesia is not necessary. Most patients are able to sleep during the entire procedure.
Do cataracts come back after surgery?
No, and the new lens stays clear. There is a normal clear membrane which is behind the lens called the posterior capsule. In some patients, the membrane may become cloudy in time. In this case, a simple laser procedure treats the cloudy membrane.
