Cataracts are the leading cause of blindness worldwide. Estimates attributing blindness due to cataracts range from 50% cause of all-blindness in middle-low income countries to 90% cause of all-blindness in developed countries. Beyond the age of 60 years old, the average person is more likely to suffer from cataracts than not. This combination of a high incidence rate among the population and highly effective treatment available makes cataract surgery the most common surgical procedure performed in the NHS. This article explores and establishes the benefits of cataract surgery from multiple perspectives.
