Performing Cataract Surgery. Most cataracts are highly treatable. Cataract surgery is one of the most common surgeries performed in the United States, with approximately 98% of patients experiencing improved vision if there are no other eye conditions present.
Once the cataracts worsen, however, cataract surgery may be necessary to correct the problem. This is where top cataract surgeons come into play. Cataract surgeons perform cataract surgery - a procedure that removes the clouded lens of the eye and replaces it with an artificial lens. This surgery is typically a safe, effective treatment for progressed cataracts, and is usually performed by an ophthalmologist (eye doctor) in an outpatient procedure.
