Cataract surgery provides a path to clear vision for those suffering from cataracts. Cataracts develop as protein builds up in the lens, blocking full light transmission and causing blurred or cloudy vision. They are very common, affecting over 22 million Americans and nearly all people over age 90. While age is a main risk factor, other risks include diabetes, eye injuries, medications, radiation, pollution, smoking, and alcohol. Regular eye exams can help reduce risks. Cataract surgery is a quick outpatient procedure that typically improves vision within a week, with full healing within 8 weeks and sometimes requiring glasses thereafter.
